Microservice security
Microservices can provide great flexibility but also introduce challenges that must be addressed.
- Service communication: Monolithic applications use in-memory communication between processes, while microservices communicate over the network. The move to network communication raises issues of not only speed but also security.
- Tight coupling: Microservices use many datastores rather than a few. This creates the opportunity for implicit service contracts between microservices and services that are tightly coupled.
- Technical complexity: Microservices can create additional complexity, which can create security gaps. If the team does not have the correct experience, then managing these complexities can quickly become unmanageable.
