Microservices

Microservices are small bits of code that let us use computers and the internet in new and exciting ways. They are like Lego building blocks that help us build new things. Just like you can mix and match Lego bricks to build skyscrapers or cars, we can mix and match microservices to think of and create big, complex systems. For example, if we want to create an online store we can use a lot of different microservices to help us make the store, such as one to help handle payments and another to help host the store website. That way, each part of the store can be smaller and simpler, and it will be easier to fix if something goes wrong.
