Is Microservices Architecture The Next Best Move For Businesses?

Oct 06,2021

Technology is getting better and better each day. Several technologies and architectural patterns have emerged and evolved during the past few years, and it only gets better with time. Microservices architecture or microservices is one of those patterns. It emerged from the world of domain-driven design and persistence.

In this article we will cover:

What is microservices architecture?
The difference between microservices, monolithic architecture, and service-oriented architecture (SOA)
The benefits and examples of implementing Microservices Architecture.

What Is Microservices Architecture?

Microservices architecture is a specific method of designing software systems that can structure a single application as a collection of loosely coupled services.

Microservices architecture is made up of several components in their own individual compartments in the software. This makes them independently upgradeable or replaceable.

Microservices architecture simplifies the process of building and maintaining certain types of applications by breaking them down into many smaller pieces that work together. Though this increases the complexity, it offers greater advantages over the monolithic structure.

Now you may wonder: Isn’t Microservices just another name for monolithic architecture and service-oriented architecture (SOA)?

Let’s clarify that for you!

Microservices Architecture Vs. Monolithic Architecture

In the current age of Kubernetes, Monolithic architecture faces many limitations. Please note a few:

Monolithic architecture is a single application. It is generally released once a year with the newest updates. Whereas, Microservices architecture is cloud-based and can be updated as required.
Monolithic architecture is slow. Modifying a small section may require complete rebuilding and deployment of the software. Microservices on the other hand are faster to deploy and quick to isolate any defects.
Monolithic architecture is harder to adapt to the specific or changing product lines while individual models of Microservices architecture enable scaling and development.

Microservices Architecture Vs. SOA (Service-oriented Architecture)

Microservices architecture is distinct from SOA. Here are a few differences:

SOA model is dependent on ESBs and so it is slower. Whereas, microservices is faster as it leverages faster-messaging mechanisms.
SOA focuses on imperative programming style, while microservices focuses on a responsive-actor programming style.
SOA has an outsized relational database. But Microservices architecture tends to use NoSQL or micro-SQL databases.

Business Benefits Of Microservice Architecture

Microservices architecture can help your business grow quicker, increase productivity, and innovate better to deploy competitive products into the market. Here are some specific benefits of the Microservices architecture:

1. Better organization for efficiency

Microservices architecture organizes business applications. It can extend those applications to support plugins for new features, devices, etc. You can easily add more features to each of those popular applications to generate more revenue.

2. Increased scalability

Microservices architecture divides applications into smaller modules. Each of these modules can operate independently enabling businesses to scale applications up or down, as required. As these modules operate independently, a fault in the single module does not mean disruption of the entire system.

If one module fails due to outdated technology or the inability to further develop the code, developers can use another module. In other words, the applications continue to function even when one or more modules fail.

This capability allows developers the freedom to build and deploy services as needed without having to wait for the entire application to be corrected.

3. Easy to maintain

It is easier to maintain and test a single module as opposed to an entire system. Since each module has its own storage and database, organizations can build, test, and deploy all the modules with less complexity.

4. Faster development

Since all modules are loosely coupled, change in one module does not affect the performance of the other. This means you can update a single module at a time leading to faster development.

5. Enhanced performance

Microservices architecture can enhance the performance of the application. It reduces downtime while developers take their time to troubleshoot the issue and bring the system back to normalcy.

6. Dynamic yet consistent

The individual modular approach in Microservices architecture is easy to replicate. This allows for consistency in applications, which in turn makes managing these modules simple and easy.

Prominent Examples of Successful Microservices Implementation

Prominent examples of Microservices architecture are Amazon, Netflix, Uber, and Etsy. Over time these enterprises refactored their monolithic applications into Microservices-based architectures. This move has helped to quickly achieve scaling advantages, greater business agility, and unimaginable ROIs.

1. Amazon

In the early 2000s, untangling dependencies was a complicated process for Amazon developers. It faced development delays, coding challenges, and service interdependencies.

However, Amazon assigned ownership to each independent service team. This allowed the developers to identify the bottlenecks and resolve issues more efficiently. Also, it helped them create a very highly decoupled architecture.

2. Netflix

Within a year of starting its movie-streaming service, Netflix was suffering from service outages and scaling challenges. It experienced major database corruption and was on standstill for three days! That is when it decided to move towards more reliable, horizontally scalable systems in the cloud.

First, Netflix moved its movie-coding platform to cloud servers as an independent microservice. This allowed Netflix to overcome its scaling challenges and service outages.

3. Uber

Uber, the ride-sharing service faced growth hurdles. It struggled to launch new features, fix bugs, and integrate its global operations. Besides, it became increasingly difficult to make minor updates and changes to the system.

Uber then decided to move to cloud-based microservices. This allowed its developers to build individual functions like trip management or passenger management. This boosted the speed, quality, and manageability of their services. Among other things, they achieved more reliable fault tolerance.

4. Etsy

Etsy experienced poor server processing time. However, with the help of Microservices architecture, Etsy created a variety of developer-friendly tools and went live in 2016. From that point forward, Etsy benefits from a structure that supports continual innovation, faster upgrades, and more.
