To implement a micro application architecture, you should consider the following best practices to ensure performance, reliability, and security.

• Applications follow a unified UX/UI framework

• Applications and services run distributed and stateless

• Use a WAF

• All applications share the same URL domain with different subpaths or subdomains

• Use an app hub for better accessibility

• Test at the application level

• Organize the team based on the business use case

• Be sure there is only one team leader or product owner

• Use CI (continuous integration) and CD (continuous delivery) software

• Have a dedicated DevOps team for the whole organization or environment

• Set a clear governance framework

• Use separate data stores

• Use circuit breakers

• Ensure API changes are backward compatible

• Follow best practices on versioning

• Promote communication among teams

• Assess security per application and per system individually

• Perform deployments individually and automatically

• Follow the best testing practice for each stack

• Use the right stack for the right app

• Do not over diversify the stack

• Contain each application individually

• Use a single logging and monitoring system

• Keep all codebases at a similar level of maturity

• Mark your application with the right maturity level, e.g., alfa, beta, released

• Use code scanner

• Use DNS addresses

• Build services that can communicate with each other
