Unfortunately, container security is much more difficult to achieve than security for more traditional compute platforms, such as virtual machines or bare metal hosts. Secrets, such as database credentials, API keys, SSL keys or encryption keys, need to be managed to protect them from discovery. Manage secrets. Run source code tests.

Containers are portable, self-contained operating environments that include applications and the dependencies they need to run, such as databases, middleware, and frameworks. Application development platforms live in the cloud and are always available. Cloud platforms are fully virtualized and, consequently, highly automated.

One of the most important concepts in analysing database performance is that of understanding scalability. When a system ‘scales’ it is able to deliver higher levels of performance proportional to the system resources available to it. In this example, we will compare MySQL 5.7.33 and MySQL 8.0.25 and MySQL 5.7.33.
