Microservices

Microservices developed in the market just a few years ago but they have already revolutionized the IT field. All the big worldwide successes like Facebook, Google, or Netflix use microservices as their new architecture.

what are Microservices?

The microservice application architecture represents a new approach to software development where developers build the application as a set of modular components or services, each with a specific task or business objective. Each of these modular components is known as a microservice, and microservices can interface with each other using Application Programming Interfaces (APIs).

Microservices architecture vs Monolithic architecture

Monolithic architecture is a software development method used to create a single-tiered application where the user interface and data access code are combined into a single program on a single platform. A monolithic software application is a single executable that can perform every task needed to deliver a specific function.

Microservices communication

In general, communication between microservices should be asynchronous, in the sense that code threads aren’t blocked waiting for responses. (It’s still fine to use synchronous communications protocols such as HTTP, though asynchronous protocols such as AMQP (Advanced Message Queuing Protocol) are also common in microservices architectures.) This kind of loose coupling makes a microservices architecture more flexible in the face of the failure of individual components or parts of the network, which is a key benefit.

Monolithic architecture pros

Easy development and deployment.

• Numerous tools facilitate easy development and deployment strategies. Developers need to perform a single chunk of deployable code instead of making updates in separate entities.

Performance.

• Better performance is a crucial advantage of monolith applications over microservices. A microservice-based application may have to make 100 different API calls to 100 other microservices to load one UI screen. Whereas in the monolith, one API call can serve the same purpose because it has a centralized code and memory.

Microservice architecture pros

Better Organization

• Since the entire code base is broken down into smaller services, it is relatively better organized. The microservices have a particular job and are not dependent on other components.

Increased Agility

• With microservices, individuals of a team can work on individual modules. Each individual can build a module and deploy a module independently, thereby reducing the team’s operational friction and increasing the software delivery’s agility. ? ??

Microservices: Use cases

Microservices are widely adopted across multiple tech giants. The implementation of microservices varies from a case-to-case basis. But some of the significant applications which run on microservices and are used on a day-to-day basis include:

Should We Use Monolith or Microservices for Business's Apps?

Choosing between the two forms of architecture is mostly a matter of looking ahead and evaluating the kinds of features and functionality you want to implement in your software.Finally, that depends on your case and your assessment of what is best for the software.

Conclusion

There are two major types of software architecture: monolithic and microservices. The latter has become extremely popular in recent years. At the same time monoliths are still there and programmers work with them as well. It means that for many the question “monolithic vs. microservices architecture” is still topical when it comes to app development.
