The traditional approach to building applications has focused on the monolith–having all deployable parts of the app contained within that single app. This has its downsides: the larger the app, the harder it is to quickly address new problems and add new features. A microservice-based approach to building apps helps solve these issues and boost development and response.
Microservices are both an architecture and an approach to writing software. With microservices, applications are broken down into their smallest components, independent from each other. Instead of a traditional, monolithic, approach to apps, where everything is built into a single piece, microservices are all separated and work together to accomplish the same tasks. Each of these components, or processes, is a microservice. This approach to software development values granularity, being lightweight, and the ability to share similar process across multiple apps. It is a major component of optimizing application development towards a cloud-native model.
But the bigger question here is why you'd want to use a microservice-based infrastructure. The goal is, simply put, to deliver quality software, faster. Using microservices is a means to that end, but there are other considerations too. Breaking your apps into microservices isn’t enough, you've got to manage them, orchestrate them, and deal with the data they create and modify.
Is your container strategy limited by your infrastructure?
Some virtual infrastructures restrict your software choices by binding you to increasingly expensive enterprise-license agreements. Migrating to open source virtualization could open your path to containers.
Deploying in the cloud? Build it for the cloud.
You have a cloud computing model—but are you building a cloud-native app? Learn how you can exploit the benefits of public, private, or hybrid models.
Microservices let your business react faster by making it much easier to develop and adapt your apps faster to meet demands. This approach to software design and architecture allows your business to get out of the multiyear “death march” that is traditional software development. Now, different parts of your development team can work concurrently on your products, in an agile manner, and deliver value to your customers immediately.

In order for a microservices architecture to work as a functional application, services need to request data from other services all the time. But what if some services get overloaded with requests? This is where a service mesh comes in—it routes requests from one service to the next, optimizing how all the moving parts work together.
Basically, a service mesh is a way to control how different microservices share data with one another. Unlike other systems for managing interservice communication, a service mesh is a dedicated infrastructure layer built right into an app. This visible infrastructure layer can document how well (or not) different parts of an app interact, so it becomes easier to optimize communication and avoid downtime as an app grows
Linux containers are, well, the best container for microservices. Containers give your microservice-based apps the best environment to run in. Containers give you more freedom and confidence, from development to production, since they include a lightweight runtime environment for your application. They also make fine-grained execution, isolation, and security possible. This lets you take better advantage of hardware and easily orchestrate services, including storage, networking, and security.
