LinkedIn Migrates from CentOS to Azure Linux

Professional networking platform LinkedIn migrates it entire workload from CentOS to Azure Linux.

Microsoft-owned social network LinkedIn revealed that it has migrated most of its servers, virtual machines, and containers from CentOS to the Azure Linux distribution. The move is to address the issue of CentOS 7 branch discontinuation, while also improving infrastructure security, reducing costs, increasing flexibility in configuration, and simplifying the implementation of new capabilities based on machine learning components.

The migration to Azure Linux has brought about significant improvements in infrastructure security. With Azure Linux, LinkedIn can take advantage of the latest security features and updates, ensuring that its servers, virtual machines, and containers are protected from threats.

Additionally, the move to Azure Linux has resulted in reduced costs for LinkedIn. By using the same operating system for both production servers and developer environments, LinkedIn can streamline its operations and reduce the complexity of its infrastructure, resulting in cost savings.

In addition, with Azure Linux, LinkedIn can easily customize its infrastructure to meet its specific needs, enabling the company to adapt quickly to changing requirements.

Furthermore, the move has simplified the implementation of new capabilities based on machine learning components. Azure Linux provides a seamless integration with machine learning tools, enabling LinkedIn to leverage the power of AI and machine learning to drive innovation and growth.

Optimized Performance with XFS and Software RAID

During the migration process, LinkedIn opted for the XFS file system and software RAID, which have shown optimal performance for most applications used at LinkedIn. This decision has resulted in improved performance and reliability, enabling LinkedIn to deliver a better user experience.

Azure Linux for Developer Environments

In addition to servers, Azure Linux is also being used in virtual machines with a working environment for developers. The Developer Desktop VM provides a graphical interface and can be accessed remotely via RDP or SSH. Although Azure Linux is not designed to provide a desktop environment, LinkedIn has successfully overcome this limitation by organizing remote access to the integrated development environments used in the company.

The use of Azure Linux in developer environments has several advantages. For instance, it allows developers to work on projects using the same operating system as production servers, which can help to reduce the complexity of development and testing. Additionally, the remote access feature enables developers to work from anywhere, at any time, as long as they have a stable internet connection.
