How enterprises choose open-source Linux to deploy the underlying architecture

For enterprises, the internal IT architecture is particularly important. When selecting an enterprise-level operating system, IT needs to be extremely rigorous. From the market point of view, enterprise-level operating systems generally have three camps: Windows, Linux, and Windows. These three camps have always been operating in parallel and show weak complementarity. However, with the continuous development of enterprises, business needs are constantly changing, and Unix is no longer popular.

However, with the continuous development of enterprises, business needs are constantly changing, and Unix is no longer popular. Although Windows occupies an absolute advantage on the enterprise's internal desktop, the Linux advantage is also obvious in the overall IT architecture. Although Linux is quite popular in the enterprise-level field, but because of its many releases, and the characteristics of each release version are different, enterprises need to be especially careful when selecting.

Linux has been operating in some computing fields for many years, such as on a supercomputer. In 2013, this year is about to pass, linux and open-source software have quietly dominated all aspects of the computing field, from cars to the cloud, to end-user computing.

You can argue whether Linux is emerging in the desktop field, but no one can deny the influence of linux on cloud computing. Apart from Microsoft's Azure, other major cloud computing software platforms, including Amazon's EC2 cloud computing, Google's computing engine, and various OpenStack implementations, are all based on Linux and open-source software.

Open source is a trend, but not equal to free

Currently, Linux distributions that are widely deployed in enterprise-level fields should include RedHat, SUSE, Centos, Fedora, and Debian. The biggest benefit of deploying a Linux system on servers is low cost and high performance. At the same time, open source can help enterprises get rid of the constraints of a single vendor. Many open-source technologies are outstanding in terms of stability and security, but 'open-source is not completely free'. using open-source technologies and architectures is also costly for enterprises.

Technology is a threshold for enterprises to choose open source. Although open source frees enterprises from their dependence on large IT vendors and achieves controllable technology and cost, however, enterprises also need to face the maturity and sufficient capabilities of their own technologies and teams, especially the strength of their independent development capabilities. Cultivate and forge a mature technical team. Without professional technical service support, relying on the technical team of the company to solve all problems requires self-testing and continuous trial and error, this process also has a certain cost. However, open source is the trend of the times. Open source software also has good stability and security.

Advantages and disadvantages of some common Linux releases. generally, Linux releases are divided into two types: Release versions maintained by commercial companies and release versions maintained by community organizations) the latter is represented by Debian:

RedHat Enterprise Linux is charged and focuses on the Enterprise Server market. In particular, version 6 can be regarded as the basic unit of cloud deployment and has good virtualization functions.

SUSE Linux is one of the oldest commercial releases and originated in Germany. The stability is good, and there is a beautiful graphic interface, which greatly simplifies complicated settings.

CentOS is based on the source code of RHEL, slightly modified and re-compiled. There are many users, because CentOS can be downloaded for free and upgraded for free.

Fedora is a well-known Linux release. It is a fast, stable, and powerful operating system built by global community enthusiasts for daily applications. It allows anyone to use, modify, and re-release freely. The version is updated quickly, and new versions are released every six months. There is a quantitative application in the personal and commercial fields.

Debian is a popular non-commercial release version. It adopts the Linux kernel, which is easy to use and pays attention to details. Its unique DEB package format is flexible and can be customized for installation.

When talking about how enterprises should choose the appropriate release version, generally, small and medium-sized enterprises choose RHEL or SUSE for deploying Linux. Both vendors can provide after-sales technical support and services. For enterprises with strong technical strength, Centos, Debian, and Fedora are selected among many.

At the enterprise-level server system level, it is safer to select Red Hat and SUSE. On the one hand, it ensures functionality and stability, and on the other hand, it can provide technical support, this will save a lot of trouble for enterprise operation in the future. Of course, for enterprises, it is up to them to decide which Linux to deploy based on their actual situation and needs. There is no best, but the most appropriate.

 

In addition, in the new era of cloud computing and big data, the future of enterprise-level Linux is also changing. Linux is developed and serves the cloud on the Internet. Currently, 8 of every 10 cloud-based applications are supported by Linux. This is because it is portable, secure, scalable, and reliable, while still open and standards-based.

Cloud requires choice and flexibility, while open source can provide more freedom and choice for people. We believe that Linux will be one of the main cloud operating systems in the future, in addition, we will see that Red Hat Enterprise Linux allows application software to accept various virtualization solutions from many vendors and computing, storage, and network resources on cloud services, and its stability and security are higher.

IT is undeniable that the Linux operating system has been serving as the foundation of traditional IT for decades and plays a leading role in innovation, which is widely used in enterprises. In 2014 and the future, Linux will continue to play an important role. With the migration of various resources and data to the cloud, Linux will play a greater role in the cloud and become an inevitable trend in the cloud era, we will wait and see in the future.
