What are microservices?

Microservices is an architecture in which the application is exposed as loosely coupled services that can be developed, deployed and maintained independently. Each exposed service is called a Microservice. Each service performs a unique function.

The particularity of this architecture is that polyglot architecture is supported. For example, if a team is working on one of the microservices using Java, Spring Boot and MySQL, another team can work on another microservice using Python, Node JS and NoSQL.

Different microservices may use a different version of the same programming language.
Different microservices may use different programming languages.
Different microservices can also use different architectures.

Q)Why microservices?
In the case of monolithic applications, there are several problems such as
Same code base for presentation, business layer and data access layer. The application is deployed as a single unit.
Complex to maintain and scalability is a problem.
Microservice solves the above problems.
Microservices are ideal when a monolith or existing application needs to be modernized.
For new software development, if the key business drivers are reduced time to market, higher quality and scalable software, lower costs, faster development, or cloud-native development, microservices are ideal.
Each service is independent and offers the flexibility to choose the programming language, database and/or architecture.
Separate services can be developed, deployed and maintained independently.

Q) What are the advantages and disadvantages of microservices architecture?
Benefits of Microservices Architecture
1) Freedom to use different technologies
2) Each microservice focuses on a single capability
3) Supports individual deployable units
4) Allow frequent software releases
5) Ensures the security of each service
6) Several services are developed and deployed in parallel

Disadvantages of microservices architecture
1) Managing a large number of services is difficult.
2) Communication between microservices is complex.
3) Increased efforts for configuration and other operations
4) Difficult to maintain transaction security and data limits
5) Due to the decentralized nature of microservices, more microservices will mean more resources, hence high investment
6) Debugging issues is more difficult unless proper instrumentation is followed during design and development.
7) Microservices will require a large team with the right mix of experience in design, development, automation, deployments, tools and testing.

Q) When to use microservices?
Reduce time to market,
Better scalable software,
Reduced costs,
Faster development,
Cloud native development
It makes sense to adopt a microservices architecture, if the team size is large enough, because each service will require its team to develop, deploy, and manage it.
Deadlines and skills of team members are a constraint.
If rapid results are required,
choose microservices architecture only if the team also has experience in microservices.
Do not use this architecture for a simple application that can be handled by a monolithic application.
So you first ask yourself if we really need a microservices architecture
