What is Microservices Architecture?
Microservices are an architectural and organisational approach to software development in which software is made up of small, self-contained services that communicate using well-defined APIs. Small, self-contained teams own and operate these services.
Microservices designs make it easier to expand and develop applications, allowing for more creativity and faster time-to-market for new features. Microservice Architecture structures an application using loosely coupled services which after these collections can be independently deployed, developed and for maintenance.
To learn more about Microservices, its essential to know why to use Microservice architecture, so lets learn about Monolithic Architecture first.
What is Monolithic Architecture?
Monolithic architecture is the traditional model for designing softwares. With Monolithic architecture processes are tightly coupled and altogether run as a single service.
Monolithic architecture is like a big container where each component is dependent on one another, for example we have an e-commerce site
Some of the Disadvantages for Monolithic Architecture are:
- For Large & Complex applications it is difficult to maintain them.
- For single change also need to redeploy complete application leading to Slow Development.
- As Application runs as single service it consumes more memory to read whole data everytime and hence is Unscalable.
- If a single service goes down it leads to collapse of complete application hence Unreliable.
- For any upgradation in technology need to modify whole application hence Inflexible.
Monolithic vs Microservices
Now, you might have got the difference in both the architectures and why Microservice is preferred over Monolithic Architecture.
With Microservice all the components of application are independent where each process runs separately as a service. These services are able to communicate using defined APIs.
As each process runs as a service, individual services can be modified and upgraded and so we can scale the application.

Benefits of Microservices
Benefits
Improves Scalability and Productivity
On difficult projects, large teams are frequently required to collaborate. Microservices allow projects to be broken into smaller, self-contained parts. As a result, teams can act independently in terms of domain logic, reducing coordination and effort. Furthermore, the teams in charge of each microservice can make their own technology decisions based on their requirements. The internal structure of each unit or container, for example, is unimportant as long as the interface works well. As a result, a microservice can be written in any programming language, allowing the responsible team to choose the appropriate language for their teammates.
Integrates well with legacy systems
Monolithic systems are difficult to keep up with. Many legacy systems are unstructured, untested, or rely on obsolete technologies. Microservices, fortunately, can work alongside traditional systems to upgrade the code and replace outdated components. Integration is simple and can alleviate many of the issues that have rendered monolithic systems obsolete.
Cross-functionality
Microservices are ideal for teams that work remotely. Microservices give you the independence and flexibility to work autonomously whether you have staff all over the world or multiple divisions. Technical decisions can be made fast, allowing for seamless integration with other systems. It's never been easier to work across departments.
