Web Edition is mainly for building and hosting Web applications, Web pages, and XML web services. It is designed to be used primarily as an IIS 6.0 Web server and provides a platform for rapidly developing and deploying XML Web services and applications that use ASP.NET technology, a key part of the .NET Framework. This edition does not require Client Access Licenses and Terminal Server mode is not included on Web Edition. However, Remote Desktop for Administration is available on Windows Server 2003, Web Edition. Only 10 concurrent file-sharing connections are allowed at any moment. It is not possible to install Microsoft SQL Server and Microsoft Exchange software in this edition without installing Service Pack 1.
Windows Server 2003 Web Edition supports a maximum of 2 processors with support for a maximum of 2GB of RAM. Additionally, Windows Server 2003, Web Edition cannot act as a domain controller.
Windows Server 2003, Standard Edition is aimed towards small to medium sized businesses. Standard Edition supports file and printer sharing, offers secure Internet connectivity, and allows centralized desktop application deployment. The initial release of Windows Server 2003 was available solely for 32-bit processors; a 64-bit version supporting the x86-64 architecture (AMD64 and EM64T, called collectively x64 by Microsoft) was released in April 2005. The 32-bit version will run on up to 4 processors with up to 4 GB RAM; the 64-bit version is capable of addressing up to 32 GB of RAM.
Windows Server 2003, Enterprise Edition is aimed towards medium to large businesses. It is a full-function server operating system that supports up to eight processors and provides enterprise-class features such as eight-node clustering and support for up to 32 GB of memory. The 64-bit versions of Windows Server 2003, Enterprise Edition are capable of addressing up to 1 TB of memory. Both 32-bit and 64-bit versions support Non-Uniform Memory Access
Windows Server 2003, Datacenter Edition is designed for infrastructures demanding high security and reliability. Windows Server 2003 is available for x86, Itanium, and x86_64 processors. It supports a maximum of up to 32 processors on 32-bit or 64 processors on 64-bit hardware. 32-bit architecture also limits memory addressability to 64 GB, while the 64-bit versions support up to 1 TB. Windows Server 2003, Datacenter Edition, also allows limiting processor and memory usage on a per-application basis.
Windows Server 2003, Datacenter Edition has better support for Storage Area Networks (SAN). It features a service which uses Windows sockets to emulate TCP/IP communication over native SAN service providers, thereby allowing a SAN to be accessed over any TCP/IP channel. With this, any application that can communicate over TCP/IP can use a SAN, without any modification to the application.Windows Server 2003, Datacenter Edition, also supports 8-node clustering. Clustering increases availability and fault tolerance of server installations, by distributing and replicating the service among many servers. Windows Server 2003 Datacenter Edition also supports Non-Uniform Memory Access.
Windows Compute Cluster Server
Windows Compute Cluster Server 2003 (CCS), released in June 2006, is designed for high-end applications that require high performance computing clusters. It is designed to be deployed on numerous computers to be clustered together to achieve supercomputing speeds. Each Compute Cluster Server network comprises at least one controlling head node and subordinate processing nodes that carry out most of the work.
Windows Storage Server
Windows Storage Server 2003, a part of the Windows Server 2003 series, is a specialized server Operating System for Network Attached Storage (NAS). It is optimized for use in file and print sharing and also in Storage Area Network (SAN) scenarios. It is only available through Original equipment manufacturers (OEMs).
Windows Storage Server 2003 can use RAID arrays to provide data redundancy, fault-tolerance and high performance. Multiple such NAS servers can be clustered to appear as a single device. This allows for very high performance as well as allowing the service to remain up even if one of the servers goes down. Windows Storage Server 2003 can also be used to create a Storage Area Network, in which the data is transferred in terms of chunks rather than files, thus providing more granularity to the data that can be transferred. This provides higher performance to database and transaction processing applications.
Windows Home Server
Windows Home Server is an operating system from Microsoft based on Windows Small Business Server 2003 SP2. Windows Home Server is intended to be a solution for homes with multiple connected PCs to offer file sharing, automated backups, and remote access.
