A server-side application can be a mix of presentation, business logic, database, and application integration. But even top software development companies cannot assure that these have to be single-tier and lightweight!
When you want to start the new project development, there is always a question of what architecture to choose.
There are two possible variants: monolithic architecture that is considered traditional and microservices.
The terms ‘Microservices’ and ‘Microservices Architecture’ refer to the same thing – the technique of developing a software application as a collection of loosely coupled services that can be developed, deployed, and maintained independently.
Microservices is a type of service-oriented architecture (SOA) where each of the services are fine-grained and, at the same time, responsible for a distinct task within the application.
Microservices architecture is best suited to Agile development practices where application changes are expected to be dynamic, fast-paced, and on-demand.
This is because a microservices architecture enables easy and efficient implementation of changes in specific elements of even large applications, without interrupting continuous delivery and deployment.
Monolithic Application vs. Microservices Application
A microservices-based application is the opposite of a monolithic application where all components of software were tightly packed together to form a single unit.
Scalability:Each microservice can scale independently without affecting other microservices.
Availability:Even if one service fails, other microservices are highly available, and the failed microservice can be rectified very quickly with minimal downtime as well.
Agility:Â As mentioned above, changes in a particular microservice can be completed and deployed very quickly which makes it a highly suitable architecture for ever-changing business requirements (meaning a highly agile environment).5.
Polyglot Persistence:Â Each microservice can choose its own type of database based on the Use Case requirement.
Thus, the business code in a microservice is straightforward to understand since it caters to one business functionality.
Faster Deployment: Since microservice caters to only a single business functionality, the amount of codebase is simplified considerably which creates rapid deployment.10.
