How to choose the server operating system

The server is becoming more and more important when choosing the right operating system. The server's operating system plays a dominant role in the organization and implementation of business activities. Now, companies have greater selectivity in operating systems. But we should also recognize that the operating system is critical to the success of the business. If the wrong operating system is chosen, the business loss may be astronomical. People are reluctant to use an operating system that cannot support it when the next generation of powerful applications comes along. While it may be effective to integrate multiple operating systems, interoperability issues are sometimes involved. Therefore, in many server operating systems, enterprises must choose an operating system that suits their needs. So how can companies choose the right operating system? There is very little information on this in the entire IT media. The following is a summary of this information for the author, combined with several mainstream server operating systems on the market, so that you can choose the server operating system that suits you. At present, there are three main types of server operating systems: one is Windows, the representative product is Windows Server 2003; the other is UNIX, which represents HP-UX, IBM AIX, etc.; and one is Linux, which is a rising star. However, due to its openness and high cost performance, it has achieved considerable development in recent years. Below, we will select some of the representative products and introduce them one by one. Windows Server 2003 Windows Server 2003 is Microsoft's latest product for server operating systems. Its predecessors include Windows NT Server and Windows 2000 Server. The simplified Chinese version of Windows Server 2003 was officially launched on the Chinese market on May 22, 2003. The Windows Server 2003 family of products includes features and features that users want to support mission-critical Windows Server operating systems such as high security, high reliability, high availability, and high scalability. Versions include: Datacenter Edition (32-bit and 64-bit) This is built for companies that require strong scalability and high availability to build mission-critical solutions for enterprise databases, enterprise resource planning (ERP) software. High-capacity real-time transaction processing and server consolidation provide a solid foundation. Enterprise Edition (32-bit and 64-bit) This version is suitable for critical use in medium and large organizations. Standard Edition It is aimed at small and medium-sized enterprises and departmental applications, with emphasis on basic functions such as file services, print services and collaborative services. Web Edition Provides a web hosting and service system platform for users who are rapidly developing and deploying web services and applications. Windows Server 2003 is a multitasking operating system that has been improved on top of Windows 2000. It handles a variety of server roles in a centralized or distributed manner as needed by the user. Some of these server roles include: File and Print Server, Web Server and Web Application Server, Mail Server, Terminal Server, Remote Access/Virtual Private Network (VPN) Server, Directory Server, Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP) server, Windows Internet Naming Service (WINS), streaming server. Windows Server 2003 also provides users with five valuable benefits: 1. Easy to deploy, manage, and use. The familiar Windows interface makes Windows Server 2003 easy to use. Effective new wizards simplify installation and day-to-day server management tasks for specific server roles, even if you don't have a full-time system administrator. In addition, system administrators have some new and improved feature designs that make it easier to deploy Active Directory. 2. A secure infrastructure. Windows Server 2003 enables organizations to take advantage of existing IT investments and extend these benefits to partners, customers, and suppliers by deploying key features such as cross-forest trust in Active Directory services and .NET Passport integration. The scope of identity management in Active Directory spans the entire network, helping to secure the entire enterprise. 3. Enterprise-class reliability, availability, scalability, and performance. Increased reliability with a host of new and improved features, including memory mirroring, hot-add memory, and stateful inspection in Internet Information Services (IIS) 6.0. In order to seek higher availability, Microsoft Cluster Services currently supports clusters of up to eight nodes and geographically dispersed nodes, and supports multiple systems ranging from single processors to 32-way systems. 4. Adopting new technology and reducing TCO. Windows Server 2003 provides a number of technologies to help organizations reduce total cost of ownership (TCO). For example, Windows Explorer allows administrators to set resource usage (processor and memory) for server applications and manage them through Group Policy settings. Network Attached Storage (NAS) can help users merge file services. 5. Easy to create dynamic intranets and Internet Web sites. IIS 6.0 is a built-in Web server in Windows Server 2003 that provides enhanced security and a reliable structure. This structure provides isolation from the application and greatly improves performance. HP-UX HP-UX is a UNIX operating system developed by HP and has a high reputation in the industry. Currently, its version has been upgraded to 11i, and there are 11i v2 for Itanium processors and 11i v1 for RISC processors. HP-UX 11i v2 provides a complete suite of mission-critical features for users of Itanium systems. These include enhanced reliability, availability and maintainability, Internet and web application services, directory and security services, system management, and 64-way performance scalability. The system is the industry's operating system that provides users with 64-way Itanium processor performance scalability and mission-critical UNIX performance to meet the demanding applications in the market. The system also features two security suite tools that enhance and simplify the security of HP-UX servers. It also provides an extended set of features, including enhanced single system availability and memory recovery. The product is architecturally fully compatible with previous versions of HP-UX 11i data, resources and binaries, providing investment protection for users and application developers. HP-UX 11i v2 also enables resource compatibility with Linux IA-32 programs and binary compatibility with Linux Itanium-based processor programs. HP-UX 11i v1 is targeted at RISC processors and offers a wide range of partitioning, high availability, and management technology solutions with Serviceguard, nPartitions, vPartitions, and workload managers. IBM AIX 5L There are many UNIX operating systems available today, but only one includes IBM's experience in creating business solutions for customers around the world. And it also provides support for 64-bit platforms by implementing affinity with Linux. This is IBM AIX 5L. AIX complies with the Open Group's UNIX 98 industry standard and provides comprehensive scalability for these applications through full integration of parallel operation support for 32-bit and 64-bit applications. It runs on all IBM p-series and IBM RS/6000 workstations, servers, and large parallel supercomputers.
