Server Virtualization

Server Virtualization is Virtualmin account, which consists of a website, email, and FTP access are associated with all domain names. Virtual Server has the administrator account called Virtual Server Owner. Virtual Server Owner can create additional email addresses, ftp accounts, and websites, with limits set by Reseller or Master Administrator who has made Virtual Server.

Sub-Server - generally made ??by the Sub-Server Virtual Server Owner, Sub-Server is a secondary domain name in the Virtual Server. Virtual Server can have as many Sub-Server that have been determined by the Reseller or Master Administrator.
 

Is a way to make the right domain name to another. Suppose we choose a domain conto.com and conto.net, and we want both of them have the same website, you can assign an alias conto.net be conto.com

Account Basics in Virtualmin

Master Administrator - a root user of the system that can manage all aspects of the server.

Resellers - is a user created by the Master Administrator. Resellers can set up your Virtual Server to another user. However, the features to create an account just for Virtualmin Reseller Pro.

Virtual Server Owner - an administrative user of Virtual Server and all of its sub-Server Aliases. This user is created by the Master Administrator or Reseller.

Mail / FTP Users - are part of a particular Virtual Server, and made ??to have access to email, ftp or both. In general, the user is created by Virtual Server Owner, although they can also be made ??by the Reseller or Master Administrator.

Server Hosting

Hosting is a place or internet service to create web pages that you created online and can be accessed by others. While Hosting Is It Alone: ??internet services that provide resources to rent servers to enable organizations or individuals to put information on the internet such as HTTP, FTP, EMAIL or DNS.

Server hosting consists of a combination of server-server or a server that is connected with high-speed internet network.

Type - Hosting Types There are:
There are several types of hosting services are shared hosting, VPS or Virtual Dedicated Server, dedicated servers, server colocation.

1. Shared Hosting is using shared hosting server with other users of the server is used by more than one domain name. This means that a single server there are some accounts that distinguish between one and another account with a username and password.
2. VPS, Virtual Private Server, also known as Virtual Dedicated Server virtualization is the process of the operating system software used by the server. Because this environment is a virtual environment, it is possible to install an operating system that can run on other operating systems.
3. Dedicated Server is the use of a dedicated server for greater application and can not be operated in a shared hosting or virtual dedicated server. In this case, the provision covered by the company hosting the server which usually works together with the vendor.
4. Colocation Server is a rental service where to put the server used for hosting. Servers supplied by customers who typically work with vendors.

Why Bloggers Need Hosting?

Yep, as a blogger you must be aware of or do not definitely need a place to publish your writing to the world of the internet. For example if you have a blog on WordPress.com, Blogger.com, Multiply.com, DagDigDug.com, and other blog services, you automatically have used hosting services they provide. But if you choose to self-hosted Bloggingly like this, then of course you have to have your own hosting rental.

Choosing a Good Web Hosting Service
When you decide to have a blog or website hosting sebdiri, then you should be able to pick and choose a good web hosting service. What should you look for when choosing hosting for your blog or website is:

1. Your need for space and bandwidth. The more your writing, the more space will be needed. The more visitors your blog, the greater the bandwidth required to prevent server full load
2. Note the services and features of the points you will hosting blog or website. It could include what software is on the hosting and support of their hosting services.
3. Target readers. If you choose to target readers of the country it is better to use a local server just to better conserve bandwidth. But if you choose glogal targets, it would not hurt you to choose a server abroad as in the United States. But this situation is not absolute.

Understanding what is a dedicated server

What is a dedicated server? Dedicated servers can be defined as a server that is rented separately and independent. Services dedicated server makes it possible to run demanding applications with high workloads that can not be operated on a shared hosting and VPS. Usually the dedicated web server provides a set of physical servers complete with its operating system. To log in to the web server you will gain root access so you yourself can perform server maintenance through access available.

Lack service what it is dedicated server

Although the service is what it has the advantage of a dedicated server, but what is a dedicated server service also has some shortcomings, such as:
- The high cost of renting a dedicated server.
Currently dedicated server rental fees ranging from Rp 500,000 per month up to $ 2,000,000 per month depending on the specifications of the computer that you rent a dedicated server.
- Operation of a dedicated server requires mastery of high technology.
Not just anyone capable of running dedicated servers. Some of the knowledge that needs to be mastered include: hardware and software servers, networks and the Internet, databases, and more. Besides the experience of the world internet network server is also required.

Conclusions about what is dedicated server

From the description of what a dedicated server above it can be concluded that a dedicated server is recommended especially for those who require high computing services with full access control. But to operate a dedicated server seems to need people who are experienced in managing internet network server. Besides the expensive monthly rental fee also makes the service less desirable dedicated servers internet users

Hopefully this article about what it's dedicated servers above can be beneficial to you and can be an inspiration for us to further develop the business spirit again in the future.

Mail Server

This time I will discuss how to create a mail server on Windows 2003 Server Operating System. As I will discuss later on the Create Mail Server by using the features, facilities and functions that are available in Windows 2003 Server, Mail Server installation, Configuration E-mail server and client configuration E-Mail using Outlook Express, and for the implementation I'm using Windows 2003 Server Enterprise Edition.

The discussion begins with the workings of e-mail, the components involved (MUA, MTA, MDA), common protocols (SMTP, POP3, IMAP4), and a variety of mail servers in a Windows environment (ranging from actual Groupware Server with Proprietary Protocol to the Internet Mail Server is an RFC-compliant); until the reasons for selecting a specific product (in this case MDaemon). Here the discussion a bit wide to sample propietary Protocol and why it is not good (eg the "Recall Sent Mail", "For Your Eyes Only", and the case winmail.dat :-()

Next we discuss two examples of topology mail server, which is behind a Firewall Mail Server and Mail Server that deal directly with the Internet cloud: what the pros and cons of each of these topologies. Also about the design of the installation, where should we separate storage location for the Operating System, MDaemon, Mailbox, and log on separate drives (and if budget allows, use a SCSI disk).

We begin the installation and initial configuration, ranging from domain and DNS (here the workings of DNS also reviews more specific), delivery method (direct delivery or relay to a specific host or a combination of both, and what are the advantages / disadvantages of each way) , setting a timer, the number of session / thread (what is meant by SMTP Inbound / Outbound and POP Inbound / Outbound; following the determination of the number of sessions with relevance CPU utilization and bandwidth), Preprocessing, Archival (and a similar but alternative archival via Content Filter), Auto -pruning, and the Unknown Mail Delivery. Here we also discuss the concept of DomainPOP and MultiPOP in MDaemon.

Next we concentrate in the areas of security, ranging from what is the Open Relay and how to shut it down, DNS Blacklist, use spamfilter (following the example of the calculation of scores and learning Spam Assassin Spam / Ham), SMTP Authentication, tarpit, AntiVirus (Inline SMTP-time Virus Scanning In, different from ordinary AntiVirus AntiVirus for E-mail, normal risk for using AntiVirus on-access scanner on MDaemon folders, virus definition updates to the frequency and size of files that are not great). Here I also discuss the SPF and DKIM, as well as things that must be considered when implementation.

Because time is tight, I began to explain to the exclusion of the structure that had been prepared before the presentation. Finally, we discuss the implementation of the Content Filter, for example, to block the delivery of mailing lists (eg yahoogroups) and downstream bandwidth savings by receiving only one post yet spread to our internal server. Also about blocking a certain attachment to certain groups of people as well (eg Powerpoint attachment is only allowed to persons only). In addition, Bandwidth Throttling also discussed.

Unfortunately due to time constraints (already delayed one hour because so many things were discussed and fun discussion), eventually have to end at 10 pm. Though there are many things that have not been discussed, ranging from how to read / search logs, User Accounts, Mailing List, Gateway, WebAdmin, WorldClient, etc.. Finally we agreed to discuss further on the mailing list CEC-Smg@yahoogroups.com. My hope that this discussion brings positive benefits for colleagues who followed him.

Online server

Automate the entire backup, storage and recovery lifecycle of business servers.
Real-time protection of apps, databases and file data

Prevent data loss with our automatic protection of key business systems such as Exchange and SQL. Create multiple policies for applications, system information and files.
Cloud storage in multiple bullet-proof data centres

Having data mirrored in two geographically independent facilities ensures that it is always recoverable – more so than in your own premises.
Simple web portal for central management, reporting & alerting

Manage machines and policies from one easy-to-use web portal. Diagnose and understand issues before they occur – and receive automatic alerts of unplanned events.
Certified end-to-end security systems and processes

Ultra secure Tier-4 EU data centres, combined with ISO27001 certification, ensure compliance with legal and industrial regulations.

Data is continuously protected

No longer lose 24 or even 48 hours' worth of data. Instead retrieve an individual file or an entire system from as little as 15 minutes ago. Simply browse to the data required, choose the date and time, and click to begin a restore. You'll even be alerted when the job is complete.
Automatic protection of Applications and System State

Key applications such as Email, Financials or CRM are no longer complex to protect. Complete protection of Microsoft Exchange is simply a matter of ticking a box. As is protecting the system state of an entire server ready for a disaster recovery scenario.
Multiple backup policies; multiple-year archives

Not all data is equal. So create multiple backup policies with differing rules. Protect email and applications in compliance mode with real-time changes and a seven-year archive; or just ensure basic file data uses a simple overnight backup, stored for 30 days. The choice is yours.
Time-of-day and day-of-week bandwidth control

Squeezing a lot of data up a congested internet connection is a challenge. That's why you can now easily select how much of your bandwidth that backup can use. Trickle-feed incremental changes during the working day at just 25% of the bandwidth – and enable 100% during the evenings or weekends.
Incremental backup – incremental restore

Not only can you backup incrementally, but you can perform incremental restores too. A large database can be recovered from our cloud storage in a fraction of the time normally required by other online services. The system will compare the current onsite version and only recover the changes required.
On-site Storage and Turbo Restore Appliance

Get the best of both on-site disk backup and cloud-based storage. Our Turbo Restore Appliances range in size from 1Tb to 16Tb – they seamlessly slot into the backup process and store multiple versions of your system for super-fast recovery.
Cloud-based control of multiple server locations

A secure web portal provides complete management of all protected devices. From any location at any time you can create policies, run reports and kick-off restores – including redirected restores from one server to another. No more needing log on to the network to manage backup and disaster recovery.
Automatic alerts of key events

The power of cloud backup is in the reliable fit-and-forget nature of the solution. But when things do not go as planned, automatic alerts to named personnel help ensure that remedial actions can be taken before it’s too late.
27001 audited security standards

Data is encrypted on protected servers before it leaves your facilities – it is sent down secured connections to our tier-4 vaults, where it is held in an encrypted state. Data is instantly replicated to a second geographically separate vault for ultra-high availability. And ISO 27001 security processes ensure high standards surround all operations.

Linux Web Server

How To Create an Apache based Linux website server

Create a web server with Linux, Apache, FTP and bind DNS: This tutorial covers the Linux server configuration required to host a website. The Apache web server, FTP server and DNS configuration are covered. The Apache web server is required to serve the web pages, the FTP server is required for users to upload content and the DNS server is required to resolve the domain names so that a URL entered into a web browser will point to your web server and properly serve the correct pages. The configurations presented will include virtual hosting which will allow a single Linux server to support multiple web site domains.

Web Site Prerequisites:

This tutorial assumes that a computer has Linux installed and running. See RedHat Installation for the basics. A connection to the internet is also assumed. A connection of 128 Mbits/sec or greater will yield the best results. ISDN, DSL, cable modem or better are all suitable. A 56k modem will work but the results will be mediocre at best. The tasks must also be performed with the root user login and password.

No single distribution seems to have an advantage. A Ubuntu, SuSe, Fedora, Red Hat or CentOS distribution will include all of the software you will need to configure a web server. If using Red Hat Enterprise Linux, both the Workstation or the Server edition will support your needs except that the Workstation edition will not include the vsFTP package. It will have to be compiled from source or use sftp.

Software Prerequisites: The Apache web server (httpd), FTP (requires xinetd or inetd) and Bind (named) software packages with their dependencies are all required. One can use the rpm command to verify installation:

    Fedora Core 1+, Red Hat Enterprise 4/5, CentOS 4/5:

       rpm -q httpd bind bind-chroot bind-utils system-config-bind xinetd vsftpd
       

    RPMs added FC2+: system-config-httpd
    RPMs added FC3+: httpd-suexec

    Red Hat 9.0

       rpm -q httpd bind xinetd vsftpd

    A Red Hat 8.0 wu-ftpd RPM may be installed (Newer version 2.6.2 or later with security fix wu-ftpd-2.6.2-11) or install from source.

    Red Hat 8.0

       rpm -q httpd bind xinetd wu-ftpd

    Red Hat 7.x:

       rpm -q apache bind inetd wu-ftpd

    Use wu-ftpd version 2.6.2 or later to avoid security problems.

    SuSE 9.3:

       rpm -ivh apache2 apache2-prefork bind bind-chrootenv bind-utils vsftpd

    Note: The apache2-MPM is a generic term for Apache installation options for "Multi-Processing Modules (MPM)s "prefork" or "worker". If you try and only install apache2 you will get the following error:

       apache2-MPM is needed by apache2-2.0.53-9

    Also see Apache.org: MPMs

    Ubuntu (natty 11.04) / Debian:

       apt-get install apache2
            
       apt-get install bind9
            
       apt-get install vsftpd

    Ubuntu (dapper 6.06/hardy 8.04) / Debian:

       apt-get install apache2 apache2-common apache2-mpm-prefork apache2-utils
            
       apt-get install bind9
            
       apt-get install vsftpd

One should also have a working knowledge of the Linux init process so that these services are initiated upon system boot. See the YoLinux init process tutorial for more info.

FAX Server

A fax server (or faxserver) is a system installed in a local area network (LAN) server that allows computer users who are attached to the LAN to send and receive fax messages. Fax messages can be stored as printable word processing, graphics, database, or spreadsheet files. Scanned documents can be sent as fax messages, allowing a computer and scanner to effectively emulate a dedicated fax machine.

Definition Fax Server
Fax Server is a software that has key functions such as fax machines. In umumnyamekanisme fax machine is an electronic machine that can receive and send fax fax.Mekanisme Fax Server itself walking / running with the help of software modem emulator software modememulator where it will receive data digital fax / send data through a digital faxmenjadi T.38 protocol.

Advantages of Fax Server

•Less Paper; while receiving fax data from telephone transmission line, we can melakukanconfigure at will, whether directly to the media-print paper or on-pooling to digital data files.

•More Flexible User Friendly: Without having to leave the desk, we can send a fax / receive faxes from your computer to our work.

•Reduce malfunction on Fax Engine; obstacles often faced from the fax machine is receiving fax data ketikasedang, suddenly fax machine damage / hang / paper jam.Dengan use Fax Server, we can reduce the risk of failure and risk untukmeminta others to resend the fax, because the data is already stored faxes automatic digital robin.

•Centralized Data documents

Requirement of Fax Server
1.Computer / Notebook
2.Windows XP Professional Original CD, because we need the dll file that existed at folderi386
3.Modem External / internal
4.Line telephone [direct line]

Linux Servers

This article discusses the understanding of linux. understanding of linux is a free open source operating system which is free for distributed under the GNU license. so you are allowed to install on your computer or copy and distribute it without having to pay. Linux is a derivative of Unix and can work on a variety of hardware ranging from inter koputer x86 to RISC. With the GNU (Gnu Not Unix) you can get the program, complete with source code (source code). Not only that, you are granted the right to copy as much as you want, or even change the code sumbernya.Dan was all legal under license. Although free, GNU license allows those who want to attract fee for copying and sending program.
The most important freedom of Linux, especially for programmers and network administrators, is the freedom to obtain the source code (source code) and the freedom to change it. This implies a few important things. Safety first, the second dynamics.
If commercial software does not allow you to know sumbenya code then you'll never know if the program you buy from them it is safe or not (often called security by obscurity). Your life in the hands of the vendors. And if there is a notice about the bugs of the commercial software, it is often too late. With Linux, you can examine the source code directly, along with other Linux users. The development of Linux users as an open community, making bugs will quickly known, and as soon as it did the programmer will fix the program. You yourself also determines the appropriate code in accordance with the basic hardware and other software to be implemented. Like a car, you can modify at will, even though the machine, in order to obtain the desired shape.
Disclosure of the source code also allows the operating system is growing rapidly. If a program with a closed system and is only developed by a particular vendor, at most about one thousand to five thousand people. As for Linux, with open source code, developed by volunteers around the world. Known bugs faster and penambalnya program (patch) more quickly available. Approach to the development of this operating system called Bazaar. Conversely Chatedraal very closed system and only focus on one or two developers only.
linux has now evolved into many distros (distributions), for example, is a distro Redhat, Debian, Suse. is currently a very popular linux distro in use in Indonesia is distro Ubuntu is derived from Debian.

Linux Virtual Server

1.Understanding the Linux Virtual Server

Linux virtual server (LVS) is a major open-source alternatives that provide solutions to make the system load balancing. As noted in the home site virtual linux server Project, Linux virtual server (LVS) is "a highly scalable and highly available server built on a cluster of realservers, with the load balancer running on the Linux operating system" The point of the real servers are machines computer that actually serve the existing request. Real servers can be connected using a LAN or WAN speeds. And machine spearhead server cluster is a director, in the form of a single server that connects real server with the client from the intranet or internet (outside the cluster system).

 2. Linux virtual servers with OSI Layer Preview.

The basic concept of the network is never separated from OSI Layer, including virtual linux server system that works by balancing network loads. OSI is divided into seven layers, each of which contains a communication protocol for exchanging information between two or more computers, among others:

    Physical layer (layer 1), a bottom layer that serves to mengubat data bits into electrical signals that will pass through a transmission medium.
    Data Link layer (layer 2), this layer provides a data format, frame creation, control and data flow errors.
    Network layer (layer 3), the main task of this layer is to address the provision of setting and managing network equipment network traffic.
    The Transport layer (layer 4), the transport layer is responsible for the integrity of the data in the transmission process.
    Session layer (layer 5), the layer is responsible for building, maintaining, and terminating sessions between applications.
    Presentation layer (layer 6), serves to resolve differences of data formats, compression and data encryption.
    Application layer (layer 7), is the uppermost layer of the OSI kelingkungan user interface.

Linux Server Software

Your operating system Linux users? If you use the OS, maybe you should know the proper usage to run on the server that you use in your office or place of business. Some views may be a consideration for choosing the right Linux, as described below:

Corporate Business

Say you have a company with several hundred to several tens of thousands of employees. What do you need? The answer is quite simple. The first choice you have Red Hat Enterprise Linux.

Why? Since Red Hat is powerful enough these days.

Red Hat has the support of big business and it's easy to get certified technicians, administrators, and engineers are competent on RHEL (Red Hat Enterprise Linux). It is supported on a variety of hardware support. Are you using x86 rack servers, blade servers, IBM POWER systems, or mainframe, there RHEL for you. In short, Red Hat is the best standard of Linux business.

Is RHEL is too expensive for you? Here, you get what you pay for. But there are two others who enter the business category of Linux distributions to note that Oracle Linux and SUSE Linux Enterprise Server (SLES).

Oracle Linux is basically a copycat version of the Community Sector RHEL.Tetapi most prefer RHEL. SLES, on the other hand, features the admin setup, YaST, which is very useful to make the size of the branch office and the addition of another branch.

Let's say you already have a team of staff who do not embrace Linux RHEL, Oracle, or SLES. In this case, you may want to consider Debian. This is the Linux community, but, for those who understand its ins and outs, Debian works very well. Debian, however, reserved for the non-expert Linux

Small Business

Let's say you only have a few hundred people in your company or even just a few dozen. What do you do now? Well, all the above options are still valid. Here you can estimate the budget you need. RHEL servers are easier to manage when you are dispersed office locations, but more SLES intended for small offices. Please you use both options and the decision is in your hands.

At this point, if you've had a tough few Linux administrator and want financial efficiency, you can use Red Hat, SUSE and Fedora and openSUSE (http://www.opensuse.org / en /). Unfortunately you can not be supported from Linux companies because you choose to downsize. But, if your IT staff understand Linux well, you probably do not need support from the company Linuz above. For example, there are twenty-four office PCs and servers - using open SUSE OS and works well.

What about Ubuntu, the most popular brand for the Linux desktop. There is also Ubuntu Linux Server. You can use Ubuntu Server for large companies. However, for large-sized enterprises should be the choice fell to Oracle, Red Hat, or SUSE, which has a lot of experience in handling large data-center installations. For a server rack or two (at most), Ubuntu may be an option.

Dedicated Server

Lately a lot of hosting providers competing to offer dedicated server hosting packages. With the increasing cheapness of the price of the computer, dedicated server rental prices also fell. For the layman may be a dedicated server is less familiar to them. But for people who are experienced in managing internet network server, then what's the term dedicated server is certainly not foreign to their ears. The following article will explain clearly about the ins and outs of what a dedicated server.

Understanding what is a dedicated server

What is a dedicated server? Dedicated servers can be defined as a server that is rented separately and independent. Services dedicated server makes it possible to run demanding applications with high workloads that can not be operated on a shared hosting and VPS. Usually the dedicated web server provides a set of physical servers complete with its operating system. To log in to the web server you will gain root access so you yourself can perform server maintenance through access available.

With a dedicated server anyway, you have complete control of your server. You are free to configure the server according to the specification of your requirements. This condition is of course different from shared hosting service where you do not have control of the server. You are limited only to configure your website in cPanel menu only.

On a dedicated server, you can use these servers to perform full testing web applications, hosting services, databases, and other Internet services. To use a dedicated server, you can simply set everything out of your desk. While dedicated server hosting services laid on, you manage Dedicate server remotely from your desk.

What service excellence is a dedicated server

As mentioned above, any service that a dedicated server has the advantage of full control of all the activities that occur on a server. So all resource / server resources such as processor cores, RAM, hard drives can be set according to your needs. With full control rights will certainly provide comfort and security of your website becomes more secure.

Services dedicated server suitable for large business events and handle high data traffic. Dedicated servers also have the ability to make more than one domain name, can build a better email service, has the support of databases and software are endless.

Lack service what it is dedicated server

Although the service is what it has the advantage of a dedicated server, but what is a dedicated server service also has some shortcomings, such as:

- The high cost of renting a dedicated server.

Currently dedicated server rental fees ranging from Rp 500,000 per month up to $ 2,000,000 per month depending on the specifications of the computer that you rent a dedicated server.

- Operation of a dedicated server requires mastery of high technology.

Not just anyone capable of running dedicated servers. Some of the knowledge that needs to be mastered include: hardware and software servers, networks and the Internet, databases, and more. Besides the experience of the world internet network server is also required.

Conclusions about what is dedicated server

From the description of what a dedicated server above it can be concluded that a dedicated server is recommended especially for those who require high computing services with full access control. But to operate a dedicated server seems to need people who are experienced in managing internet network server. Besides the expensive monthly rental fee also makes the service less desirable dedicated servers internet users

Hopefully this article about what it's dedicated servers above can be beneficial to you and can be an inspiration for us to further develop the business spirit again in the future.

Cloud Server

Some time ago I read an ad in a few offering cloud server hosting / hosting at a very cheap price, but after I read the details was not a cloud server. They apparently offer VPS and Cloud Linux. What exactly is cloud server?

Cloud Linux and VPS cloud server is not

Cloud Servers must have these components:

•      Consisting of more than 1 serverly one server means no cloud
•      Failover: automatically when server 1 down then taken over by another server
•      Load Balancing: automatically load distributed to members of the cloud server
•      Session Maintenance: automatic session id in-maintenance at cloud level, so that in the event of transfer of the session server service is maintained.

Unfortunately some ads promoting Linux as VPS and Cloud Server.

What is Cloud Linux?

Cloud Linux is an operating system RHEL derivatives such as CentOS, but added the ability to limit the use of PER USER resources. So it's similar to Cloud Linux Dedicated Servers are divided into a number of VPS. So that each user in the Cloud Linux will not overload limits given suit. For example:

Definition of Cloud Computing

If the mean cloud computing is cloud computer. Like the one on Wikipedia that cloud computing is a combination of the use of technology (computing) and the development of Internet-based (cloud). Cloud computing is a method of computing where IT capabilities are provided as an internet-based services.

Let more understand more about cloud computing itself, I love simple picture. We can imagine cloud computing is like an electricity grid. If we need power, we do not have to have power. We just need to contact your electric service, ie PLN to connect our homes with electricity and we are enjoying it. And we do the payment in accordance with the amount of use.

If electricity could aja, why computing services can not? For example, if a company requires the application of CRM (Costumer Relationship Management). Why do companies have to buy the app, buy hardware for the server and have to hire dedicated IT experts to maintain the server and the application?

Well, this is where cloud computing plays. In the example above, the company has been providing Microsoft CRM application that can be directly used by companies that require earlier. Companies that need it to stay contact the company Microsoft to connect the company (in this case via the internet) with CRM applications and live use. And the payment is made per month, per quarter, per semester, per year or as a contract made. Thus, companies need a CRM application, did not need to make an initial investment to purchase server hardware and IT experts. That's one of the benefits of cloud computing can save the budget of a company.
