Monolithic Vs Microservices: What Are Their Advantages?

Microservices (MS) are projected to grow at 22.5% in the next four years globally. However, this does not mean that monolithic systems are becoming completely obsolete. They, too, have their benefits. And there are cases where a monolith would be better suited for a program than a modern approach. 

There are a few important points to note when talking about the two methods. And that is what we’ll be looking at when we talk about their advantages. Remember that it isn’t necessary to use monolithic systems or microservices exclusively. They can also be used together to achieve an effective solution when applicable.

What are Microservices?

An MS approach to development helps simplify the program greatly. It provides a suite of modular components and services. This enables the large and complicated program to be divided into separate parts. These individual components can function on their own, without interference. 

These services have their logic and their database to work with. They can also work as a distributed system with the processes being able to talk to one another. 

MS architecture is being heavily used by tech giants such as Amazon, Netflix, and Google. Earlier, they were all using the monolithic structure but have now updated their software. Since they are big companies with multiple teams assigned, they can afford to do so. 

With the growth of this form of architecture, many companies consider MS to be the way forward. That is mainly because it helps their business grow faster. 

With that said, let’s have a look at the advantages of microservices: 

  • Since the units are independent, they are very organized. This helps in business and tech capabilities. 
  • Changes can be made without having to go through the entire code.
  • The possibility of making mistakes is lesser due to the boundaries between microservice units. 
  • Performance flexibility allows the entire process to be executed faster. 
  • Each service is scaled independently as required. This leads to cost savings, as the entire app does not have to be scaled. 
  • Microservice architecture makes the code easier to understand. This helps developers work through the program easily as well.  

What is Monolithic Architecture? 

Monolithic programming is the traditional way to build a program. These types of applications are built on a single code base. They can have a variable number of modules, which depends on the complexity of the program. 

The main difference between monolith Vs. microservice programs are that the monolithic programs can’t be divided. They exist as a unit and are completely indivisible. Microservices rely on dividing the program up into simple and logical parts to achieve a better result. 

While it calls for a simple structure, there is a lack of modularity in monolithic design. This means that any changes that have to be made will have to be to the entire stack. And architects of the monolith will have to sift through the code to do so. 

Now, let’s take a look at the advantages of monolithic programming: 

  • Less complicated, which makes it easier to implement simple workflows. 
  • Since they are local, there is a lot less latency involved which reduces processing time. 
  • They are applicable for startups or companies with simple business models due to their simplicity. 
  • Since they are cheaper and require less technical knowledge, they don’t need a lot of investment.
  • Crosscutting concerns are less as the different parts are all placed in a single place. 
  • Debugging and testing become faster due to the speed of end-to-end testing. 
  • This also enables developers to deploy the units faster.  

Monolithic Vs Microservices: Which One Should You Choose? 

If you still think that choosing the right software architecture is a boring and difficult task, you are wrong. It’s as simple as choosing between Best Bitcoin Loans, another current trend. 

A monolithic structure would be best when there is a need for a simple process. When being used by a start-up or a small company that doesn’t have a vast business model, they are also recommended. 

Microservices, similarly, would be recommended for vast business models. In other words, those that have multiple facets and need to be online 24×7. Since they are more expensive in comparison, a group of expert technicians will be required to make such a program run properly.
