Let's run down some pros and cons of a microservice architecture.

Pros

Here are a few of the positive points of a microservice architecture:

• Easier integration and deployment than traditional monolithic applications and services
• Microservices are organized around specific business capabilities
• When change is required, only the specific microservice needs to be changed and redeployed
• Enhanced fault isolation

• Integration to external services is made easier

Cons

• Testing can be more involved
• Duplication of effort and code can occur more often
• Product management could become more complicated
• Developers may have more work when it comes to communications infrastructure
