Architects can build, deploy, and scale microservices independently using microservices architecture. According to some advocates of microservices, monolithic app architecture is dead. Microservices may be alluring, but monolithic architectural styles are still very much alive.
An application that is not so complex might be best handled by a monolith-first approach. Analyze several benefits of Building the Monolith that make it a better choice for certain development scenarios.
Defined Boundaries
As a result of microservices, heterogeneous technologies can be used to build services and then glued together. While there is a lot of existing tooling geared toward microservices, it’s hard to track them down and make sure they are always up and running. Organizations must spend a lot of time and money on tool implementation and integration alone, and reliability of the architecture hangs in the balance.
In my opinion, this is one of the greatest advantages of monolithic architecture. As boundaries become distinct in a monolith, they become distinct. By recognizing the services and boundaries, teams can build a microservices architecture if desired. You shouldn’t expect when you move to a distributed architecture to solve tracking problems in your monolithic app.
Testing Made Easy
There are numerous tools that make it possible to test and debug microservice-based apps, such as profiling tools, static code analyzers and test frameworks. If the coupling is loose, finding out where the problem occurred in execution is a nightmare.
The benefit of microservice-based applications is they can isolate and tolerate faults more efficiently, but monolithic architectures have the advantage of it being easier to test things when they’re all in one place.
Developers are Less Confused
Organizations need to ensure that their teams are trained and prepared to deal with the challenges that microservices architecture can pose. You will need your team to have members who are knowledgeable about building, deploying and managing microservices.
Working with microservice architecture can be challenging if your team lacks the right skills. This architectural change is not without its challenges, especially for developers used to monoliths. Changes that can be avoided from a business perspective are best left to your developers.
Direct Communication
Data belonging to another microservice or access to services provided by another microservice may be needed by a microservice. Your microservices-based application could become chatty if it is not designed efficiently, resulting in unnecessary communication.
There are no Moving Parts to Secure
In monolithic as well as microservices architectures, security is a key issue to address, but each has strengths and weaknesses.
Any security issue in a monolithic application extends to all of its components. When a security issue arises, teams frequently find it challenging to isolate the issue since they cannot shut down the entire application.
What is the Best Option for You?
Before you choose an approach, consider the advantages and disadvantages of monolithic and microservice architectures. You should follow this basic rule of thumb: Consider microservices architecture only if your project is incredibly complex and as a monolith it wouldn’t be possible to develop, deploy, scale, and manage.
