How Product Giants are Going Big with Microservices

For the past couple of decades in the arena of Information technology, a product’s success is directly driven by the ability of a producer to quickly absorb the contemporary technology and deliver to the dynamic customer expectations. The ones that don’t, succumb to the market unpredictability and technological disruption. 

A report by NGINX about 1,800 IT professionals state that 75% of the organizations are on their way to adopt microservices architecture, while the rest 25% are already using it in production.

The Genesis Of Microservices

Microservices today is a diligently adopted development methodology by some of the big players of the internet. Ever since Dr. Peter Rodgers first introduced the term “Micro-Web-Services” during a presentation at the Web Services Edge conference in 2005, it has come a long way in bringing about a radical change in software development.

At the Top of the Ladder

Walmart was failing consistently for two Black Fridays after it replatformed it’s archaic application architecture in 2012 only to see Conversions go up by 20% literally overnight and mobile orders by 98% instantly saving them tons of computing power and money.

Amazon serves millions of customers at a time with a seamless interface. Similarly, the tech giants like Spotify, Netflix, eBay, Twitter, SoundCloud, PayPal and many more have come out to be a huge success with microservices. 

What are Microservices?

Before moving on to how adopting microservices helped these internet giants in obtaining an edge in such tough competition, let’s first look at what microservices are and how they function:

Microservices architecture is another groundbreaking software development technique that break the monolithic application development into smaller independently managed modules that perform indisputable and discrete tasks, and are connected to one another with universally accessible APIs.

The main idea behind the architecture is to differentiate tasks into processes that can be independently managed.

Here is how scaling property of microservices differs from the monolithic development approach of applications:

So each service runs one process and manages its own database. This lets development teams work with a decentralized way to build products and also lets each service to be deployed, redeployed and built independently. 

Why Product Giants are the Most Influenced?

Though monolithic architecture works well for many applications, many developers find it a cumbersome approach in certain cases, particularly the product based enterprises that have to address an ever-growing consumer base. Let’s take the case of Netflix, a revolutionary entertainment service that streams about 350 million hours of video content per day for approximately 120 million subscribers in about 200 countries.

With this amount of complexity, broadcasting quality video content in a matter of seconds to the user is not a piece of cake. So, Netflix breaks down the entire application into around 700 microservices, each to control one of the parts of what makes up the entire Netflix workflow: One microservice stores the programs you watched, one charges the monthly fee from your account, the other one lets your device play the correct videos and so on. Now Netflix engineers can make changes to any 700 of these microservices and can incorporate new changes making sure that the rest of the services in the application works fine in the meantime. That’s the recipe that works!

Now that you know how microservices work, let’s take a look at some of the key takeaways that every enterprise gets from using Microservices:

Microservices Architecture: Benefits At Glance

  • Modular Approach: Microservices have given firms a modular approach of building applications so now each functionality of their app can be deployed and then redeployed independently without having to trade-off the integrity of their application. 
  • Continuity due to Modular Independence: If one module stops working within a framework, others will continue to work. This does wonders in larger applications that remain unaffected by the failure of one of the components.
  • Linguistic Versatility: Code for different services can be written in different languages based on what works best for which service. 
  • Instant integration and continuous delivery: Microservices enable using open-source continuous integration tools such as Jenkins, etc. and makes continuous delivery possible at every stage.
  • Ease of Modification with Organised Code: Microservices eases the work of developers manifold. It helps them do away with redoing everything from scratch everytime a change is desired by making that particular module modifiable as a single entity.
  • Scalability, Reusability, Efficiency: With Microservices, a company that aims to grow by leaps and bounds has an architecture that can scale. Just like Spotify has done with multiple components spread across multiple servers and data centers.
  • Good Security Monitoring: Microservices give the companies a reliable security monitoring with the isolation it provides to all the modules. A security problem that is bound to happen in one module can be avoided in rest of modules in time. 

As the technology and user consumption patterns keep evolving, newer and better techniques of software development continue to resurface. But the real fruit here lies in due diligence in understanding what works best for a particular use case. Where a microservices architecture works best for one enterprise, another enterprise may find a monolithic approach much suitable. 

As you adopt one trending methodology, there will be some key challenges and glitches in terms of infrastructure management, development techniques and team management. So, take time to understand and plan and stay tuned for more on microservices on our blog!
