When you start your business, you can’t predict how large it’ll become. You will probably build your applications using technologies that satisfy your immediate needs, but as you grow, these technologies simply won’t scale as effectively. And one day, eventually, you will find these technologies hindering your growth.

Even the world's most powerful corporations have gone through this. They had no idea how tough it would be to grow and manage monolithic architecture in the future when they built them.

Let's have a look at the stories of these leaders to understand the benefits and drawbacks of monolithic apps versus microservices. These insights from microservices architecture companies will come in handy when you plan the architecture of your own application.

How Can You Use Microservices to Improve eCommerce?

Due to the fact that you can use microservices to break down a complex application into smaller services that work together in harmony, focusing on specific functions and features become easier. You can scale each and every service independently, and make sure it is available for your users. 

eCommerce platforms are rapidly evolving, by incorporating newer features in the system to provide a seamless experience to their customers. With microservices, you can develop, test, integrate and scale your features faster and more efficiently.

For instance, if you plan on integrating an advanced search engine for your application or add more payment options, you don’t have to redeploy your entire application. Your self-contained teams can work on different features independently and you can roll out changes quickly, and encourage innovation.

Why Are Tech Companies Embracing Microservices? 

Tech companies are embracing microservices due to the increased flexibility and scalability that they offer. Microservices allow companies to build large, complex applications without having to manage and maintain a monolithic code base. Instead, they can break down the application into small, independently deployable components that can be developed, tested, and deployed in isolation. This allows for faster development cycles, improved scalability, and better fault isolation. Additionally, microservices enable teams to work on different components of the application simultaneously, improving collaboration and time to market.

Some Microservices Architecture Companies

Microservices Architecture Companies 

Starting as a tiny bookstore, Amazon has now expanded to become the world's largest e-commerce platform (and microservices arvhtecture companies), offering books, periodicals, music, DVDs, videos, electronics, computers, software, shoes,  clothes and accessories, jewelry, tools and hardware, and more.

Amazon, like many other commercial behemoths, began as a two-tier monolithic app. As Amazon's business grew, the scalability of its technology became an issue.

At the Amazon’s re: Invent Conference in 2015, Rob Brigham, senior manager at Amazon AWS said that “If you go back to 2001, the Amazon.com retail website was a large architectural monolith.”

 Amazon's architects realized that the company's current approach with monoliths was restricting its growth, and it was time to switch to a more flexible architecture. Every aspect of the platform would be offered by a microservice, and those services would communicate with one another using APIs (application programming interfaces). At the time, the word "microservices" didn't even exist. But that's essentially what they set out to explore and build.

Amazon was able to automate operational processes and scale services based on traffic and current business demands by using the cloud for microservices. As a result, Amazon adopted a continuous delivery strategy, allowing it to develop faster and deploy more flexibly.

If you want to get an in-depth insight on how Amazon switched to cloud-based microservices from bulky monoliths, check out this talk by Werner Vogels, VP, and CTO of Amazon.


Netflix was one of the first monolithic architecture companies to recognize that it is ineffective for complicated applications and the earliest monolith to microservices examples.

In 2008, a single blunder resulted in catastrophic data corruption and several days of downtime. It was then that Netflix's architects made the decision to port the entire application from monolithic to an AWS cloud-based microservices architecture.

This migration's primary purpose was to increase availability, scalability, and speed. Netflix needed to be available 24 hours a day, work fast and scale effortlessly. Engineers were able to make modifications to any portion of the system while remaining certain that the application would never go down completely by breaking it down into nearly 700 microservices, each responsible for a single functionality. Their troubles were totally fixed after they switched to AWS and became a microservice architecture company. Netflix engineers were able to scale the capacity of services in a matter of minutes using the AWS cloud.

Netflix now serves around 250 million hours of content every day to over 139 million users in 190 countries and is still growing. When you consider all of the benefits of implementing a cloud-based microservices architecture, it's evident that timely migration was one of the reasons Netflix soared high.


Best Buy created its first website internally in the 1990s. In the year 2000, the company released a new version based on IIS and SQL Server, which was later superseded by one based on ATG Dynamo and Oracle. Most of the development was outsourced from 2003 to 2010, mostly to Accenture and Wipro, which was very common for a business in the 2000s.

The application ecosystem had become extremely complicated a decade later, making simple adjustments and updates became tedious. People with vital information and context about the systems walked out the door at the end of each project due to the nature of outsourcing development.

est Buy started a transformation of its eCommerce platform in 2010. The goal was to divide the monolithic, intricately intertwined application into microservices so that we could deliver new features and respond to market changes more quickly. They adopted the Strangler Pattern, which enables you to build create new services and kill the corresponding older services. Throughout the process, they realized that migrating to microservices is tough, but worthwhile.


One of the world’s largest beverage companies, Coca-Cola, previously had all of its data centers in one geographical location in Georgia. All of its apps were running "with a single [disaster recovery] facility," recounted Danny Eng, enterprise integration architect for Coca-Cola, when speaking in a MuleSoft webinar.

According to Eng, before deciding on a platform, the company outlined its needs, which included the capacity to support a legacy platform, provide on-premise iPaaS solutions, and be flexible to the future cloud or SaaS operations.

Hence, Coca-Cola used a DevOps-based approach to re-establish communication between developers and front-end operations.


In 2011, eBay stored 9 petabytes of data, with a daily load of 5 billion database calls, 4 billion page views, and 250 billion search queries. They shifted to microservices that year. In 2011, the company shifted from monolith to microservices archotecture in a bid to virtualize the infrastructure and wanted to build a global resource pool.

eBay realized that in order to stay competitive, it needed to provide high-quality features and improvements at a rapid pace. eBay was able to address the arising challenges of the growing complexity of the codebase by dividing everything (databases, application tiers, and even the search engine) and implementing microservice architecture, which improved developer productivity and enabled a faster time-to-market while maintaining site stability.

eBay, like other microservices architecture companies, published open source solutions for the developer community while fixing their own challenges.


Etsy had been experiencing major performance issues for a few years before switching to microservices. The aim of the engineering team was to reduce server processing time; they were also dealing with concurrent API calls, which their PHP couldn't handle effectively. 

At the same time, the team had to support the creation of new features, mobile apps, and other applications, all of which required the platform to be more extensible. To address these issues, Etsy redesigned its platform and added an API as a crucial component that developers could use. Etsy's microservice architecture design is adapted for rapid experimentation and change. The new architecture allowed them to deploy 50 times a day.


In 2011, Gilt restructured their monolithic Ruby on Rails-based design into a microservice architecture. This time, they built 156 services using Scala, Docker, and AWS technologies. Gilt reorganized teams working on strategic projects in addition to modernizing their system. Their goal was to make it simple and quick to deploy code.

Gilt saw benefits from moving to microservices, including fewer dependencies across teams, the ability to run initiatives in parallel, the ability to support multiple technologies, and the ability to innovate more easily.


Spotify needed a system that could scale to millions of users, support numerous platforms, and manage complicated business regulations. Currently, Spotify has over 810 services running. Spotify was able to develop flexible structures that are easily scalable, overcome real-world bottlenecks in a short amount of time, test quickly, and version alternative solutions individually after decoupling their old system. They grew less vulnerable to large failures as well.


Uber simply needed a few things as a startup: connecting drivers and riders, invoicing, and payments. The app had to provide a single service in only one city: San Francisco. That's why it was created as a monolithic app: at the time, it was the only app that could meet all of the business needs while also implementing essential business features and maintaining a clean codebase.

But when Uber planned to expand worldwide, they chose a service-oriented architecture (SOA) – or, to be more exact, a microservices architecture – to divide up the monolith into many codebases. Uber used microservices to uncover corporate growth prospects and overcome obstacles.

Final Thoughts

These are real-life examples of major corporations who realized they were on the wrong track and decided to take a risk and entirely reinvent the system. That decision looks to be one of the reasons they've grown into the companies they are now.

All of these organizations had similar reasons for transitioning to microservices architecture companies: they started out small but quickly grew their operations to the point where a monolithic structure no longer met their demands.

If you have a business that is facing similar issues, now is the time to switch to microservices.

Amazon is often credited with popularizing the use of microservices with its Amazon Web Services platform in the early 2000s.

Netflix chose to use microservices because it is an effective and efficient way to develop and deploy applications. With microservices, software can be broken down into small, independent, and loosely-coupled components that can be developed and deployed quickly and independently, allowing for greater scalability and flexibility. This makes it easier for Netflix to quickly add new features and services, as well as quickly respond to changes in customer demand and usage.

A microservices architecture allows for greater flexibility and scalability. It also allows for faster development cycles and simpler maintenance. Additionally, it can contribute to greater reliability due to its ability to recover quickly from errors and to contain them to a single service.
