Shared hosting is known as a cheap and affordable web hosting option for small and medium sized businesses. But, when a sudden growth is noticed in the business, the features and resources that comes with a shared hosting package are not enough to run the online business effectively.

Also, compared to the VPS and Dedicated Servers, Shared hosting delivers very less protection in order to defend a website from intruders. VPS is known as a well secured hosting solution for any type of business compare to the shared web hosting. With shared hosting, the physical server space is split and allotted to every individual customer having an account on that server. If anyone client want to install an SSL certificate, he will have to use a shared SSL which is really not a secured way to accept the transactions.

In VPS, a physical server is divided into few small servers, where every virtual server acts as an independent server and offers same security, control and features that you get with Dedicated Server Hosting. As Dedicated hosting solution is not affordable by every small business, hence VPS Hosting can be a right solution and delivers same performance as dedicated server.

You can choose a VPS in two different forms: Windows VPS Hosting and Linux VPS Hosting. A deep research has shown that most of the corporate people have chosen Windows VPS Hosting as their primary hosting solution. There are number of reasons to choose windows as hosting platform.

Windows is much secure, stable and compatible with every products developed by Microsoft Technologies. Windows hosting offers various kinds of programming languages and provides support for multimedia and high graphics websites.

Going for a VPS provides you a dedicated RAM, disk space and a dedicated IP address to install your own SSL certificate. Windows VPS hosting is a very profitable and much secure option to run your online business effectively.

Active Directory first introduced with Windows 2000 server. Active Directory allows administrators to create a more flexibility Network structure. Active Directory is a Directory services. Active Directory services are based approach to Network design it allows for large distributed network environment that have a common centralized authority for network security.

2> Active Directory provides a single point of management for Windows- based user account clients and application.

Domain tree: – In Windows 2000, a domain can be a child of another domain (e.g., child.domain.com is a child of domain.com). A child domain name always includes the complete parent domain name. A child domain and its parent share a two-way transitive trust. A domain tree exists when one domain is the child of another domain. A domain tree must have a contiguous namespace

Domain forest: – A forest is a collection of trees that don’t necessarily

form a contiguous namespace (although each tree must be contiguous). This arrangement might be useful if your company has multiple root DNS addresses.Each forest has admin Group. Members of the group have authority over all the Domain trees in the forest .Each domain has a Domain admin. Group and administrator in a parent Domain automatically transitive trust relationship .This type of structure is known as a hierarchical structured.

Storage technology

There are 2 types of storage technology we can offer on our Exchange server but the choice will depend on the Exchange server organization. We offer two types of external storage.

NAS (Network Address Storage)
1>Almost any machine that can connect to the LAN (or is interconnected to the LAN through a WAN) can use NFS, CIFS or HTTP protocol to connect to a NAS and share files.
2>A NAS identifies data by file name and byte offsets, transfers file data or file meta-data (file’s owner, permissions, creation data, etc.), and handles security, user authentication, file locking.
3>A NAS allows greater sharing of information especially between disparate operating systems such as Unix and NT.
4>File System managed by NAS head unit.
5>Backups and mirrors (utilizing features like NetApp’s Snapshots) are done on files, not blocks, for a savings in bandwidth and time. A Snapshot can be tiny compared to its source volume.

SAN (Storage Area Network)

A storage area network (SAN) is a type of local area network (LAN) designed to handle large data transfers. A SAN typically supports data storage, retrieval and replication on business networks using high-end servers, multiple disk arrays and Fibre Channel interconnection technology.

1>Only server class devices with SCSI Fibre Channel can connect to the SAN. The Fibre Channel of the SAN has a limit of around 10km at best.
2>A SAN addresses data by disk block number and transfers raw disk block.
3>File Sharing is operating system dependent and does not exist in many operating systems.
4>File System managed by servers

If you are looking to setup Exchange Server for your organization the you should know the major differences between Exchange Server 2003 and Exchange Server 2007. Here I have mentioned all the major differences between Exchange Server 2003 and Exchange Server 2007.

Exchange Server 2003

Exchange Server 2003 can be run on windows 2000 SP4.Exchange Server 2003 comes in 32 bit and 64 bit applications.There is a new disaster recovery feature that is even better than before. It allows the server to experience less downtime. The Exchange Server 2003 received some features form Microsoft Mobile Information server as well. These include Outlook Mobile Access as well as ActiveSync. Improved versions of anti-spam and anti-virus were also included. Management tools for mailboxes and messages have been improved and Instant Messaging and Exchange Conferencing Server are now separate products. There are two versions available of Exchange Server 2003. These include the Enterprise edition and the Standard edition. There are many other features that are available on Exchange Server 2003.

Exchange Server 2007

When Exchange Server 2003 was released there were no immediate plans as to what would happen to the product. A 2005 edition was dropped and it was not until the end of 2006 that the new version was released. Some of the new features included integration of voicemail, improved filtering, Web service support, and Outlook Web Access interface. The new edition was run on a 64 bit x 64 version of Windows Server. This increases the performance significantly. There are quite a few improvements to Exchange Server 2007. These include better calendaring, improved web access, unified messages, and better mobility. From a system protection standpoint there is more clustering, antivirus, anti spam, and compliance included. The IT experience is improved overall with a 64-bit performance. Deployment is better; routing is simplified as well as the command line shell and GUI.

There have been many changes and improvements to the Exchange Server 2007 and it is better than ever. There are no definite plans as to what Microsoft has in store for Exchange Server but the next version will certainly be better than ever.
