You might be asking yourself, "Isn’t this the same as SOA?" Not exactly, you could say microservices achieve what SOA promised in the first place.
An SOA is a style of software design where services are exposed to other components through a language-agnostic, communication protocol over a computer network.
The basic principle of SOA is to be independent of vendors, products, and technologies.
The definition of a service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online.
Although similar, SOA and microservices are still different types of architectures.
A typical SOA is often implemented inside deployment monoliths and is more platform driven, while microservices can be independently deployable and, therefore, offer more flexibility...
