Microservices and the Future of Software Development

You don’t need to be a tech genius to recognize that the software industry continues to rapidly expand with each year. In 2019 alone, global IT spending reached a total of $3.7 trillion dollars. Additionally, market revenues are supposed to reach $560 billion dollars by 2021.

As software markets continue to expand, hardware and software providers are pivoting increasingly towards efficiency. Creating elegant software is no longer about squeezing out thousands of lines of code, it’s about creating a piece of software that grows alongside a steady stream of updates and quickly released modifications and bug fixes.

This approach of continuous integration and development represents a more dynamic approach to software development. This type of development can call into two camps – monolithic architecture and microservices architecture.

Monolithic architecture is more traditional. It’s all about using a single code base with multiple modules. Microservices, however, uses multiple services that are loosely coupled together. Monolithic architecture presents several challenges to development. It relies on having a single group of developers being able to understand an entire application – this makes it difficult to bring new people into the development cycle and quickly bring them up to speed.

But, the challenges of monolithic architecture also serve as great examples of why microservices architecture works so well.

With microservices, it’s easier to add new people because they can immediately begin working on a new module. Since Microservices are exposed over Rest API, there is a high chance that this can be used by other modules irrespective of the technologies used. Also, unused modules can be cleaned up without too much work.

Adoption of Microservices and Benefits

In microservices architecture, a large application is divided into small modular services. As such, microservices architecture is being seen as an increasingly viable way to hit business goals. It’s poised to grow by 23.4% between now and 2025. But why are so many people opting for this type ot architecture? Let’s explore some of the benefits.

Microservices are independently maintainable, testable, and deployable. The loose coupling makes them faster and easier to maintain. These independent modules communicate through a well-defined interface using lightweight APIs. By operating with standalone functionality, this allows for a complex design to be created around specific business needs. Furthermore, as a company – and technology in general – grows and evolves, microservices allow for the seamless integration of new features.

Microservices can be divided into two types: differential and integral. With differential, microservices architecture breaks down into self-encapsulated services, which can be broken down into different transactions. Through this method, a local transaction is distributed into multiple services.

Integral allows microservice applications to weave several atomic microservices into user experiences. This allows for on-demand provisioning, dynamic composition, and service level management to all be addressed.

Regardless of which type of microservices architecture you’re interested in, they each have the same benefits. They’re autonomous, meaning each component of service in a microservices architecture can be developed, deployed, operated, and scaled without affecting how the other services function.

Also, each service is built with a specific set of capabilities and a focus on solving a specific problem. Because these services are specialized, over time, if things scale, the service can be scaled up or down with it. This helps teams measure the size of their infrastructure and its needs.

The Future of Microservices

Microservice adoption is strong. So strong, in fact, that 86% of developers expect it to become the default method of application architecture in the next five years. But what does the future of microservices look like?

Well, for starters, multiple microservices. There will be increased focus on the integration layer that ties multiple microservices together.

Additionally, the future will see an increasing demand for on-demand computational resources and serverless architecture. By better tooling for rapidly building and deploying microservices will remove the need for a larger upfront investment.
