IBM-RedHatLinux's leading open-source application platform

Article title: IBM-RedHatLinux's leading open-source application platform. Linux is a technology channel of the IT lab in China. Some basic categories, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems. With the rapid improvement of the network environment, more and more enterprises see the business opportunities brought by the network, building online e-commerce not only expands the scope of customers, but also helps enterprises reduce operating costs. There are countless success stories. the 21st century ushered in the prosperous age of e-commerce, and gave birth to the commercial myth created by using the Internet. Business models are changing, but they are all based on a common infrastructure-network.

E-commerce platforms are based on websites. selecting an excellent Web platform can achieve twice the result with half the effort.

　　Benefits of the solution

In the Linux computing environment, the Web service platform mainly includes the following types: Apache, IIS, and Tomcat. The most frequently used and best-performing Web servers are Apache, apache is a free and open-source application that can run on Linux, Windows, and Unix platforms. However, Apache is the best Web server on the Linux platform because it works smoothly with Linux. Apache has excellent processing performance for .jpg,. css,. js, and. html pages. Tomcat can be used to assist in running JSP pages and servlets. this can help enterprises build an efficient website server.

As an operating system platform backed by Apache, Redhat Enterprise Linux 5 ensures effective support for it. the enhanced features enable users to use the latest technology on Linux.

Using Redhat Enterprise Linux 5 offers the following benefits:

1. security: the Redhat Enterprise Linux 5 has unparalleled defense capabilities against security vulnerabilities by including multi-level security configuration (profiles) and improved compiler and runtime buffer management technologies.

2. desktop and work efficiency: as desktop functions are greatly improved and new application development tools are increased, you can achieve good work efficiency in the Redhat LinuxAS environment.

3. Performance and Scalability: extensive enhancements to kernel, network, and input/output subsystems ensure optimal performance with the latest hardware system.

4. simplified software package: the Redhat Enterprise Linux 5 software package has been simplified and removed from the previous AS/ES/WS version, making it easier to deploy.

Server platforms are divided:

Redhat Enterprise Linux Advanced Platform-provides comprehensive server and virtualization functions for large servers (such as IBM x3950M2. the existing Redhat Enterprise Linux AS users will automatically migrate to the Redhat Enterprise Linux Advanced platform after renewing the subscription service.

Redhat Enterprise Linux-suitable for servers with a maximum of two processor slots (such as IBM x3650M2 and HS22 blade servers), with traditional enterprise linux features and all the latest features (including virtualization ), existing Redhat Enterprise Linux ES users will automatically migrate to Redhat Enterprise Linux after the subscription service is renewed.

As a file server

◆ Redhat Enterprise linux 5 provides a significantly enhanced AutoFS function, which can now be used smoothly and securely in a hybrid environment.

◆ Samba in Samba-Redhat Enterprise linux 5 provides the ability to interact with Microsoft Windows file and print (CIFS) systems.

◆ FS-Cache-is a new file system that allows data cached on a local storage device on a remote system (NFS server.

◆ Network File System (NFS)-Redhat Enterprise Linux 5 provides the latest NFSv4 implementation solution, which greatly enhances the performance, stability, and security and server-side authorization functions through SecureNFS.

◆ Global File System, logical volume manager, and distributed lock manager-to simplify seamless system development and virtualization, the basic Redhat Enterprise Linux 5 contains three independent versions (single system/guest) of distributed system technology.

● Logical Volume Manager (LVM): used to create and manage virtual storage device pools;

● Global File System (GFS): a POSIX-compliant high-performance and scalable file system. The Redhat Global File System supports a file system with a maximum theoretical capacity of 8 EB (the Redhat Enterprise Linux 5 can support 25 TB of authenticated capacity );

● Distributed lock manager (DLM): an advanced application synchronization interface.
