What Is Microservices Architecture: Benefits, Use Cases & Its Trends?

Published April 27, 2023


It’s been more than a decade since Microservices have entered the tech industry. Now, microservices architecture has become the latest love and highly preferred technology among the tech giants like Amazon, Netflix, Walmart, Coca Cole, etc. in modern software development.

Microservices trends have simplified the overall software development approach of developers, where software can be divided into small suites and independent units that are responsible for performing their respective functions and communicating through APIs.

Despite all such flexibility, often the microservices architecture got wrong. So, let’s explore in detail to eliminate any misconception about what microservices are and what it has to offer to developers and software development companies.

What is a Microservices Architecture?

Microservices follow a pattern, thus usually termed as Microservices Architecture – is an architectural style that structures an application as a group of services that are;

  • loosely coupled
  • owned by a small team
  • highly maintainable and testable
  • independently deployable
  • organized around business capabilities

The microservices architecture supports frequent, rapid, and dependable delivery of complex and heavy applications. It also supports software development companies to upgrade and evolve their technology stack.

Microservices has resolved the challenges of project scaling of a monolithic system by being as modular as possible. In simpler words, the microservices architecture helps to build an app as a part of small services, where each service runs in its own process and can be independently deployable.

Microservices are often connected and interlinked with APIs and can avail similar tools and solutions that are developed in the RESTful API and web service ecosystem. Testing of these APIs allows you to validate the data flow thorough out your microservices application deployment.

Types of Microservices Architecture

Broadly, the microservices are divided into two types;

  1. Stateless Microservices, and
  2. Stateful Microservices

a. Stateless Microservices

A stateless microservices architecture is a type of Internet Protocol where the state/status of the previous transactions/operations is neither stored nor referenced in the very next transaction/operation.

The request is raised by the sender and can be interpreted by the receiver, meanwhile, to perform this operation it doesn’t require the existence of any prior request for the execution of the current request. In this protocol, the client and server requests and responses are carried out in the current state.

Example: Sending an SMS, where sender and receiver can send and receive the message respectively at it doesn’t require any previous permission or detail to perform the message sending operation.

b. Stateful Microservices

A stateful microservices architecture allows users to record, store and find existing information and processes over the internet.

It keeps track of all the records/processes that are performed earlier and considers it as a reference point for the upcoming record/process. In stateful application, the current transaction is usually influenced by the previous transactions.

Example: Good example of stateful architecture is FTP (File Transfer Protocol) and Telnet. Some of the common applications of stateful microservices are Online Banking Systems and email.

Benefits of Microservices Architecture

1. Promotes Scalability

Companies majorly prefer microservices because of their scalable nature. The services can be easily developed and released independently without hampering the ongoing processes and don’t demand any heavy coordination efforts in the organization.

2. Agility

The microservices development is relatively small and simple, thus in case of failure, only a specific service will get affected not the entire system. Therefore, organizations can prefer to experiment with their business logic, algorithms, and new operations.

3. Technological Freedom

Microservices architecture doesn’t rely on a “one size fits all” concept. The development team can avail the freedom of selecting the best tools to develop the solution for the specific problem. Hence, for each job or issue resolution, the development team can pick their tools.

4. Code Reusability

The small modules of software enable the development team to use the functions for multiple purposes. A service builds to serve a specific purpose can be used as the building block for another feature. This allows developers to reuse the existing codes and functionalities to develop new capabilities without writing code from scratch.

5. Simplified Debugging & Maintenance

Building individual microservices is relatively easier than coding for a monolithic architecture. This enhances the developer’s productivity, simplifies debugging of codes, as the modules and functions are reused to design the new feature, and enhances performance maintenance.

6. Resilience

If one microservices fail, then others will continue to work, as these services are not dependent on each other to perform functions or operations. The microservices can be deployed in different availability zones with cloud-enabled technologies, which ensures that users never experience an outage.

What is Monolithic Architecture?

Usually, the software comprises multiple feature sets. Whereas, in monolithic architecture, all the features and modules of the software are closely packed reside in a single codebase, and are deployed as a single file.

If the software goes through any updates or changes, then those updates can’t be implemented individually. The developers need to use the existing codebase and make the required updates and then re-deploy the updated code.

In simple words, a Monolithic Architecture is like a huge container, where all the software components of the app are developed and tightly coupled, hence, the components depend on each other.

Monolithic Architecture Vs. Microservices Architecture

FeaturesMicroservices ArchitectureMonolithic Architecture
PerformanceIt requires a higher latency time to transfer info. from point A to B, which hampers the performance.It delivers much better performance due to lower latency time.
ComplexityIt is a complex architecture, to develop, and clusters and containers are highly complex which requires great management expertise.Comparatively simple to develop, and requires a single codebase and library to run the application.
TestingTesting is quite challenging. It requires additional attention to test inter-microservices interaction.Testing is easier, because of the presence of single codebase testing & debugging are convenient.
Time to MarketIt has a short time to market. It is easier to continuously implement new features and upgrade the existing ones.For MVP going with monolithic architecture is a good idea, but for a full-fledged app, it always requires high time to market.
Team StructureSmaller teams can work on individual services and own complete accountability for that.A large development team contributes to the same codebase but no one takes ownership of that.
UpdatesDue to the minimalistic nature of modules and the autonomous nature of services, quick updates can be deployed.Internal dependency within the architecture requires time to deploy updates, as multiple developers work at the same time.
SecurityInteraction between services via API creates security issues.Secure data processing and transferring are easier at the system level.
