Monolithic vs Microservices Architecture Which is Best?

It was hard for them to add new functionality and scale the monolithic platform. And scaling was essential as our client has many factories, warehouses, and suppliers, as well as a lot of raw materials and finished goods, which circulate among them. The core reason why the platform was not scalable and inefficient was its monolithic nature. Since a microservices architecture is a distributed system, you have to choose and set up the connections between all the modules and databases.

Learn about monolithic bulky, the traditional model for designing applications, where all components and functions are included in a single element. InMicroservices, we run all the applications on Containers , so the boot-up time and memory consumption of applications decrease, thus the performance of the application increases. In organizations, not one or two but multiple numbers of Containers are running. Kubernetes comes in handy because it provides various facilities like self-healing, scalability, auto-scaling, and declarative state.

Why monolithic architecture is better than microservices

For a complex streaming app, we recommend you to choose microservices architecture. For some situations, the monolithic software architecture works well. For instance, it suits startups that need to get a product up and running as soon as possible. Other companies prefer to stay monolithic despite the popularity of microservices.

In a monolithic application, we would need to recreate the entire build and perform the deployment of the entire application. Lack of flexibility – A monolithic application is less flexible than a microservices architecture. More manageable complexity – A microservices architecture breaks an application into smaller, more manageable pieces. This makes it easier to understand and maintain the codebase.

Easy deployment with one executable file makes deployment easier. Better fault tolerance – If one service fails, it doesn’t bring down the entire application. This helps ensure high availability and reliability. These modules are typically implemented as a single executable or DLL. Unfortunately, that’s true – if there is a single issue with a component, the whole app will most probably fail simply because all components are interconnected.

With a small engineering team aiming to develop a simple and lightweight application, there is no need to implement microservices. This way, a monolithic application will be much easier to build, make changes, deploy, and provide testing. Another advantage of the microservices approach is that each element can be scaled independently. So the entire process is more cost- and time-effective than with monoliths when the whole application has to be scaled even if there is no need for it.

Highly agile

A memory leak of one service, for instance, would only affect the particular service of the server-side application. But if you are unfamiliar with microservices, what is microservices architecture consider a monolithic approach with a modular structure. When your solution grows, a modular structure will let you decompose an app easily.

Why monolithic architecture is better than microservices

When these undesirable patterns arise, it may be time to consider a migration to microservices. On the other hand, a monolith architecture has a broad codebase that has dependent elements. Such an infrastructure layout is an obstacle to regular deployments, so the whole application needs to be redeployed to upgrade a single component.

Bonus: microservices best practices

As the size of the application increases, its start-up and deployment time also increases. Scalability is critical for your project and you plan to grow your development team. Each element is dependent on the others, so any change affects the whole network. As such, changes are time-consuming and need to be carefully coordinated. Also, each small update comes with redeployment.

Accordingly, a monolithic software architecture is a complex application that comprises several closely coupled functions. It describes a uniform model for the traditional design of a software program and is being replaced more and more by modular alternatives such as microservices architectures. Since monolithic apps are less complicated than microservices, their deployment is much faster and easier. Moreover, a monolithic approach is a traditional way of building applications, so developers are likely to possess all the needed capabilities. The client has reached us with a request to boost their operational efficiency, since their legacy monolith learning management system required constant synchronization. Moreover, running the synchronization cycles was time-consuming and negatively affected the system’s performance.

So, if there was a fault anywhere in the code, the complete project would derail. Furthermore, the monolithic structure was never considered a good strategy. Instead, it is the convenience and simplicity of the monolith servers that raised its worth in the app development industry. Additionally, microservices architecture sometimes adds an unnecessary complication in the delivery of the app. A key feature of microservices architecture is that the app function is split into independent modules, but APIs keep intercommunication open.

This allows everything in the monolith to be released at once. This means that, to perform well, the team has to have full competences to build and ship new features to production. They should not need to communicate with different structures. Of course, they need to fulfill the API service contracts and interfaces.

Scalability- You can’t scale components independently, only the whole application. One of the biggest mistakes that one can make when working with microservices is loading them with multiple responsibilities. In reality, every microservice should have only one responsibility in order to minimize the possible negative consequences of a service failure. In simple words, if something goes down in a microservice, the failure will be sort of isolated.

  • In order to figure out which architecture will best suit your project, it is good to formulate situations when you need either monolith or microservices.
  • Increased complexity – As an application grows, it becomes more difficult to manage and maintain.
  • Being a distributed system, it is much more complex than monolithic applications.
  • While a monolithic application is a single unified unit, a microservices architecture breaks it down into a collection of smaller independent units.

It’s down to using a script that loads your module and launches the application. Continuous Improvement is the process, where you try to improve the quality and efficiency of your team through many incremental changes. The code base of the monolith is very large due to the immense feature set.

If a single component fails, the entire application fails. Those applications work independently as a single module. Should a single microservice go down, it would not take down the entire application. One of the main disadvantages of monolithic bulky is its lack of flexibility.

Software updates can be performed more frequently, with improved reliability, uptime, and performance. We went from pushing updates once a week, to two to three times a day. However, most small businesses are still using monolithic architecture and it works well with them.

It is often used for applications that handle high traffic or load. This makes it easy to understand and maintain but difficult to add or remove services without affecting the entire application. In a microservices architecture, services are independently deployed and communicate with each other over a network, which can add some overhead and latency to the system.

For maintenance, you should be aware of .NET, Java, DB2, etc. The testing process is painless, but finding errors and making changes is time-consuming. An individual microservice may be well-tested, but when combined with some common microservices and programs, it is hard to test every configuration. Additionally, as you combine them, they may interact in unforeseen ways.

How do you convert microservices to monoliths?

Because the whole app acts as a single unit, it’s much easier to manage this area of the app’s functionality. Unit-by-unit deployment and cloud reliance cause the higher cost of the microservices app and even operational overheads. Being practiced for quite a time, the monolithic app development today refers to bread-and-butter skills that all software architects must possess. Naturally, it is easy to find experts with the expertise of this kind. To meet this need, software needs to be extendable and able to exchange data between each other. It is a reason why microservices have been spread so fast.

Each part of an entire application is independently designed, implemented, managed, and scaled in a microservices architecture. This suggests that an improvement in one application infrastructure would leave other systems unchanged. When you opt for a microservices architecture, developers have the advantage of using multiple tools, languages, frameworks, and OS to build enterprise applications for business. This reduces dependence on a single application stack and long-term interaction with it. Even if a single part of the application is facing a large load/traffic, we need to deploy the instances of the entire application in multiple servers.

How to choose the right software architecture?

As with the case of Netflix, monolithic applications can be quite effective until they grow too large and scaling becomes a challenge. Making a small change in a single function requires compiling and testing the entire platform, which goes against the agile approach today’s developers favor. As you know monolithic application codebase is single, unified, and huge. So sometimes, it becomes hard for developers to understand and handle, particularly those who are new to the project. This, as a result, will slow down the process of growth.

What is monolithic architecture?

To avoid synchronization problems within the organization, Spotify adopted microservice architecture with autonomous full-stack teams. The company has 600 developers and more than 90 teams, the functions of which do not overlap with each other. Netflix has successfully migrated from a traditional monolithic to a cloud-based microservices architecture. Now, the company receives more than one billion calls each day from 800 different devices to its streaming-video API.

This will help make the codebase more flexible and easier to maintain. There are limitations in choosing technology stack. We can not build one components in Go , another in Node.js and few others in Java .
