Migrate from Monolith to Microservice on Time!

  • Post published:November 9, 2021

Are you wondering why migrate monolith to microservices?

Around 63 percent of businesses adopted microservice architectures in the year 2018. The migration took place because the enterprises wanted to take advantage of the following offers:

  • Elimination of manual entries
  • Defeating programmatic risks
  • Providing a unified view of data
  • Enhancing the control and synchronization of systems

Single application components are tough to maintain and modify but this can be easily achieved if you migrate monolith to microservices. Applications that are built on microservice have independent servers that work separately to aid the app functionality. Hence, a need for microservices arises. A microservice architecture can be created with Node.js, PHP, Python, or Java. But why Migrate Monolith to Microservices when Monolithic has been one of the very first ways for creating web apps?

Let’s discuss its drawbacks and deduce an answer to this question:

Rising Complexity

Although monolithic architecture has its benefits, its rising complexity, in a nutshell, overpowers everything. If an app requires some changes then it should be done in a clear-cut manner rather than opening the whole codebase for the changes to be reflected. A monolithic architecture has everything embedded in it, the functionality, logic base, database processing, and background processing. All this is deployed at the same time and made live on the server at once. For some, this could be a potential benefit but it’s not an optimal way of getting things done.

Migrate Monolith to Microservice

The basic premise that monolithic applications can be tested easily or tracing the bugs might sound interesting at first but it’s not that simple when you have to make minor changes but the difficulty level is a right hook jab from Rocky. Usually, a bug can be fixed with some minor tweaking to the specific code lines but in the case of monolithic apps, entirely new work has to be initiated and deployed again. Honestly, that’s redundant and quite tedious for developers. It takes a toll on productivity levels and not to mention the sunken hours. To top it all off, scaling is something that will make you both laugh and weep when it comes to monolithic architecture. You cannot scale a part of the app, the whole app will require scaling.

We’re not saying monolithic architecture is the Lazarus pit but in all truth, it will cost your organization time, money, impairing agility and effort then it’s time to move on to something more flexible.

Less Reusability

Monolith architecture isn’t very favorable for the codebase to be repurposed and reused for something else. Everything has to be created from a newer angle in monolithic architecture, one of the major reasons why you should migrate monolith to microservices.


The amount of resources and hours it takes to implement changes to monolithic architecture web apps bumps up the initial cost of the project. The one housing structure hits hard on the project when you have to instruct the developers to do it all over again. This is why migrating monolithic applications to microservice architecture is the best way around to control.

Migrate Monolithic to Microservice

Microservice Architecture – The Problem Solver

A town, for instance, is made up of small houses. Microservice architecture is just like a town; it has small services that have their framework, database, and programming language. Every service is different from the other and they communicate through HTTP, AMQP, or TCP (a binary protocol). Companies such as Netflix, Uber, and Amazon have fully embraced the microservice model based on the magnitude at which these apps are running. This goes to show that Microservice architecture is no joke.

To put it short, microservice architecture solves all those problems that a monolithic architecture has. Such an ideal replacement! Migrate Monolith to Microservices justified.

Advantageous for all the right reasons

Before thinking to Migrate Monolith to Microservices it’s important to note the offering so you can be a better judge as to its feasibility:

Micro Service

1- Scalable

Some major changes to a certain component of the application are dealt with easily while the rest of the app and its components are safe. Unlike monolith architecture where you’ll have to scale the whole application to make it run how you see fit. You can compare this to a school system if one of your teachers isn’t in for the lecture the rest of your classes continue. A strange but understandable example.

2- High productivity levels

What we like about micro service architecture is that multiple teams can work simultaneously on building services. This way less time is consumed and teams work on optimal levels to make the application more aligned to the requirements. In a monolithic architecture, testers had to wait for the whole application to be ready which would then allow them to conduct their test and QA. But here testers can test separate services and this way more work is done in a shorter span. So to Migrate Monolith to Micro services means increased productivity levels.

3- Ease of Maintenance

These days it’s all about smooth app runs. The higher the lag and errors make users turn away. Microservice architecture with its network of separate service bases allows the team to have a better grasp of the code. This enables them to act more efficiently in delivering error-free code. A good reason to migrate monolith to microservices

4- Flexible

Microservice gives developers the liberty to use different languages and frameworks for separate services. Unlike monolithic architecture, they aren’t bound with using one single framework and language in the whole of the application. These variations can help to resolve technology-based queries.


Look, it’s all about your project nature. If your application is on a small-scale level then you should go for Monolith architecture. However, if you’re involved in something massive like Uber or SoundCloud then your best bet is microservice architecture.

Nowadays the term migration gets thrown around a lot but the fact of the matter is it’s quite difficult to perform a seamless migration so this should be taken seriously. Furthermore, you should also know that in the initial stages the effort put in to create separate services consumes a lot of time. So be mindful and choose wisely when migrating monolith applications.
