Hi product people 👋,

In recent years, API gateways have become increasingly common in modern architecture - particularly for products with multiple APIs and complex microservices.

Some estimates suggest that over 70% of companies are now using API management solutions like gateways and the market for API management is set to grow from $5.4 billion 2024 to $25.6 billion by 20311.

But what is an API gateway and why might you need one?

If you’ve heard folks at work talk about API gateways but were never quite sure what they were talking about, this edition of the Knowledge Series should help.

We’ll take a look at what they are, when you might need one, along with some real world examples from Uber and Netflix which will help us to bring to life some of the key concepts involved in working with API gateways.

Paid subscribers get full access to the series - with new topics added every month. And if you’re interested, you can upgrade to receive them.

Coming up:

  • What is an API gateway?

  • When and why might you need one?

  • Case study: how Uber and Netflix use API gateways for internal and external use

  • End to end examples to bring the key concepts to life
