Monolith to Microservices: Transforming a web-scale, real-world e-commerce platform using the Strangler Pattern

Monolith to Microservices: Transforming a web-scale, real-world e-commerce platform using the Strangler Pattern

By Kristen Womack on .

Microservices are hot these days. According to Google Trends, searches for “microservices” were almost non-existent five years ago.

Maybe your team is one of the many now moving toward a microservices architecture. And with good reason: breaking a monolithic application into smaller, simpler services increases your project’s velocity, your ability to scale, and allows you to react more quickly to change.

In 2011, I was part of the Best Buy transformation that broke down the monolith of the website into separate web services. This is the story of that transition from monolith to microservices at one of the world’s biggest e-commerce platforms—what we learned, what worked, and how you can learn from our experience—while highlighting two keys in our transformation success: focusing on culture, and using Martin Fowler's Strangler Pattern.

But first: How did we get...

You Might Not Need GraphQL

You Might Not Need GraphQL

By Phil Sturgeon on .

Do you like the look of GraphQL, but have an existing REST/RPC API that you don't want to ditch? GraphQL definitely has some cool features and benefits. Those are all bundled in one package, with a nice marketing site, documenting how to do all the cool stuff, which makes GraphQL seem more attractive to many.

Obviously seeing as GraphQL was built by Facebook, makers of the RESTish Graph API, they're familiar with various endpoint-based API concepts. Many of those existing concepts were used as inspiration for GraphQL functionality. Other concepts were carbon copied straight into GraphQL.

Facebook has experimented with various different approaches to sharing all their data between apps; remember FQL? Executing SQL-like syntax over a GET endpoint was a bit odd.

Facebook got a bit fed up with having a one-endpoint-based approach to get data and this other totally different thing, as they both require different code. As such, GraphQL was created as a middle-ground between endpoint-based APIs and FQL, the latter being an approach most teams would never consider - or want.

That said, Facebook (and others like GitHub) switching from RESTish to GraphQL makes folks consider GraphQL as a replacement for REST. It is not. It is an alternative. 

Whilst the use-cases for the sort of API you'd build in GraphQL are quite different from those you'd build with REST (more on this) or RPC, that...

Ensuring Microservices Success: Key Things to Consider

Ensuring Microservices Success: Key Things to Consider

By Janet Wagner on .

This is the first post in our Featured Guest Series! Janet Wagner shares eight tips on how your company can ensure success when moving to a microservices architecture.

Microservices are all the rage these days, and you can find blog posts on most technology news sites and blogs about the topic. Major technology companies like Amazon and Netflix have been evangelizing microservices for quite some time now. The number of businesses building microservices architectures to power web and mobile applications is growing at a rapid pace and with good reason. There are significant benefits for companies running applications on microservices architectures such as high availability, high scalability of both the architecture itself and the engineering teams developing it, and ability to innovate and add new features faster. 

If you are one of the many companies that have decided to venture into the world of microservices, there are a lot of things to consider. Do you start with a monolith or microservices architecture? How do you define the scope...
