Monolithic vs Microservices Architecture

It offers effective solutions for handling a complicated system of different functions and services within one application. Microservices are ideal when it comes to platforms covering many user journeys and workflows. But without proper microservices expertise, applying this model would be impossible.

Why monolithic architecture is better than microservices

We hope this article has helped you understand the pros and cons of each architectural style and make an informed decision for your software application. Estimating and optimizing the application’s expenses and revenues is integral to all commercial software development. Each microservice can use different technology based on the business requirements. As the size of the application increases, its start-up and deployment time also increases.

Continuous Development

The Microservices architecture pattern is the better choice for complex, evolving applications. Actually the microservices approach is all about handling a complex system, but in order to do so the approach introduces its own set of complexities and implementation challenges. Deploying a microservices-based application is also more complex.

Why monolithic architecture is better than microservices

While your application may grow over time, it remains easy to manage and update. Although most monolithic applications start as simple units, the architecture grows with time and becomes more complex. As a result, any repair effort will require what is microservices architecture a massive investment of time and resources. Most developers and engineers prefer monolithic architecture because it is the traditional way of building software programs — you work with a single codebase for the entire application.

What Are Advantages & Disadvantages of Microservices Architecture?

We’ve taken hours of interviews with successful CTO’s and distilled them into general guidelines to follow when choosing your service architecture.

Before you migrate from monolith to microservices, there are specific application-level changes that you should adopt. We will discuss several ways on a high-level to embrace microservices. ✔ Since all microservices are loosely coupled, their interdependency is greatly reduced. Hence, all the individual microservices can be scaled up to any level. For example, the number of people looking for a cab is anytime higher than the number of people booking a cab or making its payment. In such a case, the processes and the services involved in the trip booking and trip payments can be up-scaled.

What’s the difference between monolithic and microservices architecture?

However, while the microservices approach has gained popularity over the last few years, the monolith is still a viable option in plenty of situations. A microservice architecture requires more planning and design before starting. Developers must identify different functions that can work independently and plan consistent APIs. However, the initial coordination makes code maintenance much more efficient. On the other hand, in a distributed architecture, each microservice works to accomplish a single feature or business logic. Instead of exchanging data within the same code base, microservices communicate with an API.

The Subdomain of the application define the entities in its own context which are bound to that subdomain. Even though the entity may be similar or exactly the same, in a different context, it may be called differently and it may have different attributes in that subdomain. Let us now take a look at the logical structure of microservices.

What is Monolithic Architecture?

In a monolithic application, this area of functionality concerns only one application, so it is easier to handle it. With the above details, both the challenges and benefits of each can conclude that monolithic is easier to develop than microservices. Although it is easy to create a single service, this framework poses challenges. It is hard to sync the application due to the different languages, databases and even libraries used. Therefore, it is not possible to tell that the data is in sync. Not only is it huge, but it isn’t easy to modify the application.

For example, this means that during peak hours, you can just scale up, and in slower periods, you could scale it back down again. When you use the microservices architecture, you will have increased decoupling and separation of concerns. Besides, microservices allow you to build applications with failure in mind. By factoring in possible downtimes and maintenance, you get better control over unprecedented shortcomings in the future.

c. Scalability

The API gateway will convert that HTTP request into a message which is put in the queue. While adding the API gateway, care should be taken that the API gateway itself does not become a bottleneck in the application. In that case, it is desirable to create multiple API gateways for each logical subdomain which will give access to different microservices to the client. In the Microservices architecture, each service is designed to fulfil and implement one of the subdomains in the domain of the application. Another difference between the service-oriented architecture and the microservices architecture is the principle of design on which the services are created. The actual application used to run on servers which was called the web server.

  • When an application malfunctions, diagnosing the problem and debugging the code could be a massive challenge under certain conditions.
  • Due to a single codebase, it is easy for experienced engineers to build and develop a monolithic application.
  • Most applications that utilize containerization also use Kubernetes, a container orchestration system that manages the hundreds of containers often required for applications.
  • Plus, having come into the market just a few years ago, microservice demand is already expected to grow at the rate of 22.5% by 2025.
  • In monoliths, the server-side logic, the UI logic, the batch jobs, etc., are all bundled in a single EAR , WAR , or a JAR file.

You can scale individual microservices as required, which saves overall scaling costs. Requires advanced debugging tools to trace the data exchange between multiple microservices. Every microservice is an independent software entity that requires individual containerized deployment.

There may sometimes be a response from the business microservice which is sent back in another message put in the queue. The mechanism for the queue is sometimes a simple queue mechanism like RabbitMQ. Queue mechanism assures the delivery of the message even if the recipient is not available at the time the message is put in the queue. Such communication is usually between two microservices where there is only one recipient microservice. This type of communication is not possible in a non-trivial application which has many microservices catering to different sub-domains within the application. In such conditions, it is suggested to use communication through an API gateway.
