What are Microservices?

Have you ever wondered what are microservices and how are they integrated into scaling industries to build applications? This post will show some basic facts and features of this advanced approach in software development.

What are Microservices?

Microservices are a software architecture which breaks down applications into smaller elements to allow for greater agility. These parts are typically autonomous and aligned with a specific objective or business. By using this approach, large firms could launch new services and products much faster, as well as align their development experts with business goals.

Features of Microservices

In general, microservices are characterized by two main features:

– Specialized

Each component is built for a set of functions and focuses on dealing with a particular issue. When developers add more code to a component over time and the component gets complex, it could be divided into smaller ones.

– Autonomous

Each part of the service in this approach could be created, operated, deployed, and adjusted without influencing the functions of other components. Services don’t have to share their implementation or code with the others. Any communication between separate components will occur through well-defined APIs.

Benefits of Using MicroservicesWhat are Microservices?

There are many benefits of the microservices approach:

– Flexible Scaling

This technique enables each service to be scaled independently to meet demands for the application it supports. As a result, development teams can right-size the needs for infrastructure, measure the expenses precisely, and ensure availability when a service is in a spike.

– Agility

Microservices can create an organization of independent, small teams which take ownership of the services. Each team acts within a well understood and small context, and is allowed to work more quickly and independently. This shortens the cycle times of development to help companies benefit from the aggregate output.

– Resilience

Independence of each service increases the resistance of the application to fail. In monolithic architectures, when a single element fails, it could cause the failure of the whole application. But with microservices, applications could deal with total service failures by degrading functions and won’t crash the whole application.

Microservices vs Monolithic Architectures

All processes in monolithic architectures are tightly combined and run in a single service. Thus, if there is any spike in one process, the whole architecture needs to be scaled, making it more complex to add or remove a feature. As a result, it limits experimentation and creates more challenges to implement innovative ideas. Due to its single design, monolithic architectures are often at higher risks of process failures.

In a microservices architecture, the application is created as independent elements which operate each application process in an independent service. Those components communicate through a well-defined interface with lightweight APIs. They are constructed for business capabilities with different functions. This makes it easy to update, deploy, and scale each service to meet demands for particular functions.

Bottom Line

So, what are microservices exactly? Compared to monolithic architectures, microservices can provide more benefits to businesses. In addition to ensuring quicker developments of software or packages, companies can make use of this approach to align their development experts with overall business groups.
