Monolith Vs Microservices Application Architecture

To answer the question of what is good and when we first must go up and take a bird’s eye look. Contrary to a popular belief, microservices are not a panacea. If something is good for everything, it’s good for nothing. Many managers compare microservices vs monolithic architecture and want to know which is best for the current company’s project. Microservices are a fantastic way to make the digital product agile, and scalable. Monolith is good when you just want something to be done.

With every new feature, the code base will grow and become bulky. It may even reach the point when not a single developer could understand it. The next step is to calculate your available budget for the maintenance of the final product. Maintaining microservices is comparatively more costly.

Plus, a single business process can run across multiple machines, further complicating debugging. Technology flexibility – Microservice architectures allow teams the freedom to select the tools they desire. Performance – In a centralized code base and repository, one API can often perform the same function that numerous APIs perform with microservices.

monolith vs microservices pros and cons

If a particular microservice is facing a large load because of the users using that functionality in excess, then we need to scale out that microservice only. Hence, the microservices architecture supports horizontal scaling. People also consider SOA as a superset of microservices.

In a microservice architecture, we have a democracy and free market. There is a general principle that connects all but other than that, everyone’s independent. They also communicate with each other on a need-to-know basis but it’s an organism rather than a hivemind. Microservices relies on Cloud infrastructure to be effective and to scale appropriately as necessary.

The problems of network latency and security are relatively less in comparison to microservices architecture. Simple to develop relative to microservices, where skilled developers are required in order to identify and develop the services. It is very difficult to adopt any new technology which is well suited for a particular functionality as it affects the entire application, both in terms of time and cost. Now the monolith vs. microservices choice should be easier to make. Your app is quite simple and does not meet serious loads after deployment or it is already in production but does not face any issues with performance yet. The SMS is not coupled with the APP and if we need to exclude it from our project it will even be possible to delete it from our test_rails_backend directory, and nothing will change.

Developers need to become accustomed to working with the complexity of a distributed system. The UI generally consists of HTML pages or JavaScript running within a browser. Netflix attests that the migration was well worth the effort — not only were they able to expand their service, but they’ve created a more reliable service in the process. While monoliths may sometimes be overlooked because of their legacy status, they have a number of benefits. It is also possible to keep two versions of a payment microservice, working with different processing centers.

monolith vs microservices pros and cons

Each microservice will require its own infrastructure, dedicated continuous integration and delivery pipeline, and monitoring processes. Across all developers and teams involved, this can result in wasted effort and time. Also, it is common for each developer to understand only part of a monolith, meaning very few developers can explain the entirety of the application. Since monoliths must be developed and deployed as one unit, it can be difficult to break up development efforts into independent teams. Each code change must be carefully coordinated, which slows down development. There are various opinions on what type of architecture to choose.

That is exactly why both approaches coexist beautifully – each of them occupies its own niche. Let’s find out when you should choose monolithic architecture or microservices and why. Higher productivity.A monolith vs microservices pros and cons somewhat controversial point, but there is an opinion that the monolithic applications run faster due to the absence of a large number of microservices combined through the API.

For Startups Our client’s success stories speak better than words. Check out our approach and services for startup development. Monolithic architecture is a suitable choice for smaller projects that need to be delivered quickly and on a budget. It can be easily created and maintained on a small team, and the intuitiveness of the architecture allows accomplishing a lot early on. At that point, the company was already a leader on the market, with 87 million active users and 250 billion daily searches. The change to microservices was a bold move because the stakes were high.

Limitations Of Monolithic Architecture

See the video below for more on how Netflix uses serverless. It isn’t a bad idea to build a monolithic application, but it is a bad idea to let a monolithic application grow out of control. If your business has skilled and knowledgeable DevOps and developers, who possess architecture expertise. Microservices divide the system into numerous independent functionalities, and making them work smoothly is not an easy task. Consequently, they all communicate with the same database and use the same file system.

Each separate service is responsible for a separate business task, and therefore needs an individual approach to testing. In addition, services can be written using different technologies. All this complicates the process of testing the application. Complicated onboarding.It is difficult for newcomers to understand a huge monolithic application, even if their tasks include working with only certain limited functionality.

The exact architectural style you adopt for your application will depend on your unique needs, but monoliths and microservices are predominant architecturals. To determine which is right for you, you should first understand the differences between monolithic and microservice applications, as well as their advantages and disadvantages. Team structures under conventional monolithic and microservices architectures are different. Under the microservices arrangement, you have smaller teams working on individual services and holding complete accountability for the same.

What Is Monolithic Architecture

Sometimes, at the beginning of a company’s activity, we simply do not have anything to share yet – we only need one central system that will allow us to achieve business goals. So, when a company builds a new central system on which all the company’s main processes are going to be based on, it simply needs to think carefully about its choice. MLSDev team knows how to work with both microservices and monoliths correctly.

  • Complicated testing.Of course, a more complex system consisting of disparate services created using different tech stacks requires a more thorough approach to testing.
  • So, should we keep up with new architectural decisions or stay with monolith?
  • A monolith, on the contrary, provides faster communication between software components through code sharing.
  • It is important to determine which functional groups provide the most value as microservices.
  • Of course, this collapse will destabilize microservice it is responsible for, but all the rest will remain stable.
  • Scalability is one of the best microservices advantages.

“You want to make sure when there’s an issue that it’s percolated up every single time.” When you do a migration, it’s not just a technical migration, but a people and organizational change. Atlassian in 2015 was a “write the code and throw it over the wall” to the operations team who ran and deployed it. By the end of 2017, we embraced a DevOps culture of “you build it, you run it”, with every developer at Atlassian running their own services.

It lowers the barrier of adopting newer technologies as the developers have the freedom to choose whatever technology that makes sense to their project. You create a complex project and are going to leverage the most suitable solution for each feature. To save you some clicks, we will explain the difference between monoliths and microservices using one picture that represents them as food. Monolith architecture is more affordable and faster to develop.

For example, a program with 30 microservices in its architecture requires 30 calls to load each screen, which might affect performance. A monolith, on the contrary, provides faster communication between software components through code sharing. A microservices architecture addresses these challenges by breaking the application down into smaller components or services.

Monolithic Vs Microservices Pros And Cons

Latency refers to a time break between the stimulation of a certain physical change in the system and the response to it. When a microservice sends or receives data from another service, bytes are sent over a network. They turn into electrical signals and then back to bytes. It happens when your aim is to scale your application and add more functions, but later you will find it difficult to follow and manage.

Building Javascript Microservices With Node Js

Choosing the right architecture for your MVP is a daunting task, but RubyGarage has many years of experience to help you with your choice. We would be glad to answer all your questions on this topic. Vendor lock-in describes a situation when you give a vendor full control of your operations. As a result, changes to business logic are limited and migration from one vendor to another might be challenging. This way, even if data storage of one service is broken, all the others are intact and can work smoothly. If one component fails, others can fill it, using their own database.

The Backstage Pass Into Startup Tech Teams

It also has a gemfile , library dependencies, and initializers. Frankly speaking, it will be a simple daemon process with an infinite loop based on the evented architecture. It deserves a separate article, so we won’t look into it. This is appropriate if there are more than one microservice in our architecture and they are do not require sequential processing. Moreover, if you use direct communication between the main app and the microservice, the microservice will be available at some port. You will have to foresee its unavailability for the outside world .


Even if any of your microservice needs to get some data from another microservice, you can send a request to gateway microservice. Microservices abstract away implementation details, only exposing a well-documented interface, so APIs can be consumed in a consistent way, regardless of how exactly the service is built. The reason for that is a smaller number of cross-cutting concerns, such as logging or error detection. As all of these cross-cutting concerns are managed in one place, they require less experience to handle. To date, software as a service has emerged as a world popular business model for developing w…

The best case for migrating is when you can refactor your codebase without losing time. It’s best to stick with your monolith until you have a better understanding of your architecture — and the problems within it. Backend architecture they should choose when they are starting their journey to become a startup.

What Type Of Businesses Usually Implement Them?

Organizations can benefit from either a monolithic or microservices architecture, depending on a number of different factors. When developing using a monolithic architecture, the primary advantage is fast development speed due to the simplicity of having an application based on one code base. Netflix became one of the first high-profile companies to successfully migrate from a monolith to a cloud-based microservices architecture. It won the 2015 JAX Special Jury award in part due to this new infrastructure that internalized DevOps.

Responsibility for a specific, well-defined microservice results in a gentler learning curve for new hires, who can be productive much sooner. Chandler Harris is a marketing strategist and writer for Atlassian. He has written for more than 40 different publications on subjects ranging from technology, science, business, finance, and education.
