1.Background
Before formally introducing KOS to you, we will first pay attention to these issues.
Traditional operating systems face some bottlenecks in large-scale data processing, high-performance computing and artificial intelligence applications, including storage and access efficiency, data transmission and communication efficiency, parallel computing performance and other issues. In order to better improve these problems and improve performance and stability, KOS came into being! Next, let’s experience this domestic new star operating system together~
2. What is KOS?
KOS, also known as KeyarchOS, is a server operating system independently developed by Inspur Information based on open source technologies such as Linux Kernel and OpenAnolis. It supports mainstream architecture processors such as x86 and ARM. Its performance and stability are industry-leading, and it has mature CentOS migration and Replacement capabilities can meet the needs of application scenarios such as cloud computing, big data, distributed storage, artificial intelligence, and edge computing.
After understanding KOS, let’s see what improvements KOS has made regarding some of the issues we started talking about.
High performance implementation
KOS uses a variety of optimization technologies, such as memory management, disk IO optimization, network protocol stack optimization, etc., to achieve a high-performance operating system. KOS also supports a variety of hardware architectures, such as x86, ARM, etc., allowing users to choose the most suitable hardware platform according to their needs. Artificial intelligence, virtualization, cloud native and other applications based on Inspur Information KOS have been enhanced in terms of development efficiency, operating efficiency and scalability.
Modular design
KOS adopts a modular design to separate the various components of the operating system, allowing users to choose the components they need according to their needs, thereby achieving a more streamlined and efficient operating system. At the same time, KOS also provides a wealth of interfaces and plug-in mechanisms to facilitate users’ secondary development and customization.
Security Guarantee
KOS focuses on security in design and adopts multi-level security protection mechanisms, including access control, data encryption, vulnerability scanning, etc. At the same time, KOS also supports containerization technology, which allows applications to run in isolation during runtime, thereby improving system security.
Open and flexible mechanism
KOS is an open operating system, which means its compatibility is very strong and supports a variety of open source software and standards, such as Docker, Kubernetes, OpenStack, etc. At the same time, KOS also provides a rich API and plug-in mechanism to facilitate users’ secondary development and customization.
3.CentOS will stop maintenance?
Migration background
On December 8, 2020, CentOS officially announced plans to stop maintaining CentOS Linux and launched the CentOS Stream project. CentOS plans to move RHEL's forked version of CentOS Linux to CentOS Stream, so there will be the following impacts on CentOS Linux:
-
CentOS Linux 7, as a replica of RHEL 7, will stop updating on August 6, 2020, but will continue the current support plan and stop maintenance on June 30, 2024.
-
As a replica of RHEL 8, CentOS Linux 8 has a shortened life cycle and will stop updating and maintaining on December 31, 2021.
-
CentOS officially no longer provides CentOS Linux 9 and subsequent versions
In order to cope with the security risks caused by CentOS's imminent complete outage, the majority of enterprise users will definitely consider alternatives to maintain the security and stability of the system, which requires CentOS migration.
Back to our topic, the advantages of Inspur Information KOS will make it the best choice for migration! Since KOS is so excellent, how does it perform CentOS migration? The following are some of my experiences using
Traditional migration VS KOS
Traditional migration solution
1. Back up data and shut down all services 2. Install the migration tool centos2anolis: [root@localhost ~]# yum -y install centos2anolis 3. Execute the migration command: [root@localhost ~]# centos2anolis.py 4. Wait for the migration to complete. The system will prompt the migration completion information. 5. Check whether there are any remaining CentOS packages: rpm -qa | grep centos rpm -qf | grep el7 6. Verify whether the migrated system is running normally.
KeyarchOS migration plan
The KeyarchOS migration solution simultaneously launches the visual migration tool X2Keyarch, which has functions such as migration risk assessment, hardware compatibility assessment, application assessment, system configuration assessment, etc. Its in-place upgrade technology can batch upgrade existing CentOS systems to the KeyarchOS operating system. After the upgrade, the system Parameters do not need to be reconfigured, which greatly improves migration efficiency and reduces customers' migration costs.
Migration strategy: The overall migration process roughly includes five links: environment investigation, migration assessment, laboratory migration verification, migration implementation, and operation monitoring
The original system remains unchanged, the new server is used to install the KOS operating system and the corresponding business software is deployed, and then the migration tool is used to synchronize the configuration and data of the original system to the new system. The plan is as follows:
Advantage:
High degree of customization: It can be highly customized according to specific needs, which allows KOS to better adapt to specific application scenarios and hardware platforms.
Lightweight and high-performance: KOS uses a streamlined kernel and components, has a smaller memory footprint and startup time, and provides higher performance
4. Prospects for the leap forward of domestic operating systems
Domestic operating systems have made some important progress in the past few years, and are also facing many opportunities and challenges, but the future is still worth looking forward to! I think there are three major trends:
The most critical thing is the ecological aspect. I think that in the future, domestic operating systems will strive to improve their own ecosystems, including applications, development tools, drivers, etc. This will help attract more developers and manufacturers to participate in the construction and development of domestic operating systems, forming a healthier and more prosperous ecological environment.
The second is cooperation and exchange, which is very important. Through cooperation with international manufacturers, open source communities, etc., we will be able to better integrate into the global technology ecosystem and enhance the competitiveness and influence of domestic operating systems.
Then there is the expansion of application fields. Modern Internet of Things, artificial intelligence, industrial control and other fields are developing rapidly. Domestic operating systems will have the opportunity to play an important role in these emerging fields in the future and provide support for the development of domestic industries. Therefore, we must continue to expand application fields. extension
