While simple applications are easy to work with, they are difficult to update. Developers may need to recode the entire application and service. As the application rapidly develops layers and interdependencies, it https://globalcloudteam.com/ becomes increasingly challenging to understand the codebase and its underlying dependencies. For example, consider an e-commerce platform that has an online store, a payment gateway and a customer service system.

Furthermore, you can deploy services independently without affecting downstream operations. Another critical factor is microservices’ capabilities are expressed with business-oriented APIs, and the implementation of the service is defined purely in business terms. Additionally, these microservices are independently deployable by fully automated deployment tools. Scenario 1 – If you have few resources, a monolithic architecture might be an appropriate option since it is easy to create and manage.

With microservices, each of these components would be its own independent service, and they would communicate with each other through APIs. XML data is a key ingredient for solutions that are based on SOA architecture. XML-based SOA applications can be used to build web services, for example.

It is difficult to test microservices as a whole due to a multitude of independent components in contrast to the monolithic approach allowing to deploy the system locally and test it. Again, since the monolithic architecture is built as a single unit, you can do automated testing and debugging without the need to test separately each environment as with microservices. So why do microservices prevail over the monolithic approach and which one will be the most suitable for your business?

Moreover, this kind of approach limits the damage that developers can cause through manual errors and mistakes. As the application gets larger due to how its structure is tightly connected, it also gets more difficult to understand and modify. Moreover, as the codebase increases in size, the IDE starts to slow down due to the overload, in turn, causing slower development speed and startup time. I’d just like to offer a slight variation and bring about the organizational perspective of it. Not only does microservices allow the applications to be decoupled but it may also help on an organizational level.

Cloud roadmap

This process experiences some latencies and thus slower compared to monolithic. On the other hand, the microservices are relatively friendly for engineers to create. The microservices advantages of microservices over monolithic act independently, and thus users do not require knowledge of only one language to create an application. This architecture allows for different languages in various releases.

monolithic architecture vs microservices

If it will not, you can detect the bug easily because you will get fast feedback. It will be more difficult and expensive because you need to scale the whole application rather than part of the modules that need scaling. You’re fixed to one deployment platform, one operating system, and one type of database. Microservices architecture has a number of significant drawbacks. It is important to know there is always a chance of something going wrong.

Relational Databases

Do you still think about migrating your monolith architecture to microservice architecture? Before doing that, you need to make a tradeoff by considering microservice’s benefits and drawbacks. The critical point of WET is reducing the amount of shared code. Microservices usually prefer to duplicate code rather than reuse it to avoid coupling.

After your project’s estimation, you might know whether your app will need new functionalities in the future and will need to be integrated with new technology. If there is no need to upgrade the application, then monolith will be a great solution in this case. They usually run in their own environments with their own CPUs. And, finally, the more complicated the environment requires a team of engineers capable of building it, so labor costs are going to be more. For example, SoundCloud might have a new user microservice designed to onboard a user onto its application.

monolithic architecture vs microservices

As the size of the application increases, its start-up and deployment time also increases. In this way, UBER benefited by shifting its architecture from monolithic to Microservices. For Example, we all know that the number of people searching for cabs is more comparatively more than the people actually booking a cab and making payments. This gets us an inference that the number of processes working on the passenger management microservice is more than the number of processes working on payments.

Expectations of Monolithic Architecture

The application and the business logic is encapsulated in a single deployable binary called a monolith. Usually, a monolith consists of a conventional three-tier architecture, namely, a database, a user interface, and a server-side application. The below diagram represents the idea of the monolithic in a nutshell. Microservices architecture is built as small independent module based on business functionality. In microservices application, each project and services are independent from each other at the code level. Therefore it is easy to configure and deploy completely and also easy to scale based on demand.

Cost is a significant factor that comes to the executives’ mind while taking the final decision of adopting any software architecture. When considering any infrastructure, the first question that comes to our mind is, “What will be the new technology’s operational impacts? ” In case you have decided to adopt the microservices, there are undoubtedly some significant impacts that you should consider.

Service Discovery

The service interfaces provide loose coupling, which means that they can be called with little or no knowledge of how the integration is implemented underneath. Because of this loose coupling and the way the services are published, development teams can save time by reusing components in other applications across the enterprise. As a result of the shared access to theenterprise service bus , if issues arise, it can also affect the other connected services. Simple to developMany development tools support the creation of monolithic applications.

  • Hence, for more complex applications microservices architecture makes continuous deployment possible.
  • Human skills like collaboration and creativity are just as vital for DevOps success as technical expertise.
  • To deploy to other systems, you need to copy the packaged application to a different server and run it.
  • As a result, organizations are weighing microservices vs. monolithic architecture to improve software delivery speed and quality.
  • This person should enable the organization to invest in new tools, systems, and processes to make improvements permanent.
  • Before being sent to an API gateway, requests from clients are processed by an identity provider, which is a service that creates, authenticates and manages digital identity information.

It’s challenging to deploy a third-party tool that requires complicated connections to different parts of the monolithic application. Because the app can’t be broken into chunks, developers need to jump through hoops to integrate a single codebase with a third-party service with dependencies and other requirements. Adding self-contained, third-party components to a single codebase with multiple dependencies requires complicated hookups to different layers of a monolithic application. The challenge is, as the application grows and becomes more complex, you may need to integrate components written in different languages. A monolithic app poses challenges in incorporating other parts of apps or services written in a different codebase. As a result, this hamstrings DevOps teams’ ability to add features and functions that could’ve been better written in a different programming language.


At the same time, you will need to determine which functions should be transitioned first to ensure your business continues to operate smoothly. So for a car, one person puts the axles on the chassis, another fits the steering wheel, and so on. All workers on the line collaborate to get the car assembled, but they essentially work independently. • A database layer – It acts as a storage for all necessary data objects. Jonathan Johnson is a tech writer who integrates life and technology. Connect and share knowledge within a single location that is structured and easy to search.

Examples of microservices architecture

There are many patterns involved in microservice architecture like service discovery & registry, caching, API gateway & communication, observability, security, etc. As you can see, the monolithic vs microservices architecture shift isn’t always easy. However, the hardest part may arguably be deciding which functions and data go where. Once these decisions have been made, you only need to write the new microservices. Luckily, with vFunction, analyzing your monolith and accompanying databases can be done easily.

The Most Complete Platform for Microservices

✔ Each microservice performs a singular functionality and has separate deployable binaries. For example, if you change anything in the Driver Management microservice, you just need to build and deploy the Driver Management microservice and not touch the others. The figure above illustrates that every developer in the team will have the liberty to work on independent modules. Code repositories, build, and deployments are separate from one another. Since all the elements are loosely coupled with each other, it increases the agility of the entire Software Development Life Cycle .

Monolithic Architecture vs Microservices Architecture: Comparison

It also means you can scale down those services that are under less load. This is, in part, why so many companies that build SaaS products adopt microservice architecture. The microservices architecture eliminates any long-term commitment to the technology stack. Because each service is autonomous, the developers are free to use any language which best suited for the business needs. Thanks to loose coupling and independent deployability in a microservice architecture, you can perform selective or on-demand scaling. If your team has no microservices experience, start with a monolithic architecture.
