Linux is better than Windows, but how can it be managed?

Article Title: Linux is better than Windows, but how to manage it ?. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

With the gradual development of Linux, functions and stability have been gradually recognized by most users. Linux plays an increasingly important role in an enterprise's IT environment.

　　Linux advantages

1. Integration and flexibility

Linux is more flexible than Windows in many aspects. Most Linux applications can be modified by users according to different needs, and then re-compiled. Software in the open-source community adopts high flexibility and modular design.

2. Security

Rapid vulnerability repair: If you frequently access the Internet, you will often hear people say "no absolutely secure host ". Yes. However, Linux has a large number of supporters and many enthusiastic groups and individuals participate in the development. Therefore, it can obtain the latest security information and update it at any time, which is relatively safe.

3. Multi-task and multi-platform scalability

Different from Windows systems, a Linux host allows multiple users to work online at the same time, and the resource allocation is fair. This kind of multi-user and multi-task is quite good for UNIX-like systems. You can plan users of different levels on a Linux host, and each user can log on to the system in a different operating environment. You can also allow different users to log on to the host at the same time to use the resources of the host at the same time. In theory, Linux can run on any hardware platform, while Windows has many constraints in this regard. One reason many users choose Linux is to avoid vendor blocking.

4. High Stability and free of charge

Linux is an operating system developed based on the UNIX concept. It has similar program interfaces and operation methods as UNIX systems and inherits the stable and efficient features of UNIX. It is common for a host that has been running Linux for more than one year without having to shut down. Because Linux is a product based on GPL, anyone can obtain Linux freely. The installation CD released by the "installation kit" publisher only requires a small fee. Unlike UNIX, which requires huge copyright fees, it is also different from Microsoft's need to constantly update the system and pay a lot of fees.

Although the commercial UNIX System of Linux is relatively easy to maintain, there are still some difficulties in the daily maintenance and management of Linux systems:

There are many release versions, and there are some differences between products of various manufacturers. For example, SUSE, RedHat, and RedFlag are developed based on standard kernel versions, but there are still many differences in system maintenance, Software and Hardware Management, and network management. It is difficult to find a monitoring software that supports so many versions. Therefore, many enterprises only have to invest in multiple monitoring software or discard monitoring of some Linux Hosts. Now, this problem is effectively solved through multiple Linux platforms supported by Mocha BSM.

As a large enterprise, not only is there a Linux release version in use, the administrator needs to learn the maintenance of multiple systems. However, the management workload is huge because of the large quantity. In some enterprise IT environments, cluster-based Linux deployment architecture is often used, because the overall cost of using a Linux system is low, the distributed architecture can meet the high performance requirements of enterprise applications and reduce the total cost of ownership. In this way, administrators often need to maintain a large number of Linux Hosts. When the number of hosts reaches dozens or even hundreds, manual management is almost impossible to complete the tasks, it will reduce the running efficiency of the entire application system, so it is difficult to manage Linux and the number of hosts. Through unified monitoring and management, Mocha BSM can master the overall performance of the entire application system. The monitoring metrics cover a wide range of fields, including CPU, memory, disk, partition, and network, provides administrators with targeted indicator data. Flexible policy management allows you to set different monitoring policies (Monitoring frequency, metric threshold, and alarm methods) for different systems ), you can also set different monitoring policies for different sub-resources of the same system, such as a system with multiple CPUs and network adapters. There is also a friendly display interface, user-friendly design.

Multiple alarm methods are supported, including email, SMS, voice dialing, and desktop alarm, to ensure that the administrator can know the operating status of the system at any time and anywhere. Mocha BSM provides professional data reports and root cause analysis for downtime, helping administrators solve problems faster and help enterprises perform system resizing and business growth, however, the number of maintenance personnel can remain unchanged, so that end users can get higher quality application services.
