In China, the open source LAMP stack is the most popular network architecture, which is developed using PHP, runs on Apache servers, and uses MySQL as a database, all of which run on Linux. It is a reliable platform that works well and is now the most popular Internet system architecture in the world. However, it is difficult to scale properly and maintain security because each application layer has its own set of issues, flaws, and best practices. Our job is to help organizations create and run high-performance, scalable, and secure systems with the lowest operational costs, so we have a lot of experience with these kinds of issues.
