The cloud drives today’s application development and IT systems management. Modern cloud applications need to be fast, agile, massively scalable, and reliable.
Using containers can help you deploy applications that meet all of those requirements. But putting an application into a container without following a strategic design pattern is like getting into a vehicle and hoping to find your way to a new city without using a map or GPS. You might end up at your destination, but the route probably won’t be direct or the most efficient.
A microservices architecture is useful in this scenario. Microservices give you an approach to software development and deployment that’s perfectly suited to the agility, scalability, and reliability requirements of modern cloud applications.
What is a microservices architecture?
In a microservices architecture, a large application is split up into a set of smaller services. Each service runs in its own process and communicates with other processes by using protocols like HTTP/HTTPS, WebSocket, or Advanced Message Queuing Protocol (AMQP). Each microservice implements a specific, end-to-end domain or business capability within a certain context boundary. Each microservice must be developed autonomously and must be independently deployable. Finally, each microservice should own its related domain data model and domain logic. Microservices can be based on different data storage technologies (SQL, NoSQL) and different programming languages.
