However, as the two databases diverged from a shared common codebase, this presented a challenge in that it was not possible to modify the workload for MySQL or MariaDB without also changing the other. Checking database library for MariaDB Error: failed to load mariatcl - couldn't load file "/home/HammerDB-4.2/lib/mariatcl0.1/libmariatcl0.1.so":

Unfortunately, container security is much more difficult to achieve than security for more traditional compute platforms, such as virtual machines or bare metal hosts. Four types of tools are commonly used to detect software vulnerabilities: Source-code tests that are used in development environments. 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. Traditionally, enterprise applications have been monolithic, meaning all the functionality is bound together in a single code base. Microservices.
