What Are Microservices And Do I Need Them?

 In Software Development

The term microservices has been around for nearly a decade and the approach has gained popularity with many tech giants. Many organizations have taken notice and are trying to make the switch, but it’s a challenge for them. Switching from the traditional architectures to microservices requires a big change in perspective and workflow throughout an organization. They need to embrace agility, scalability, and the ability to work in parallel to various workstreams.

If your organization has tried to make the switch to microservices and struggled to do so, you may wonder if it’s worth it. Does your organization really need microservices? Let’s take a closer look.

What is microservice architecture?

Microservice architecture, or microservices, is a variant of service-oriented architecture (SOA) for developing large applications. Tech Target defines it as “an approach to application development in which a large application is built as a suite of modular components or services.” Each component is continuously developed and maintained, making it easier to develop and maintain the larger application. (Contrast that to monolithic architectures, where the entire application is developed and maintained in one piece.)

Companies have been moving towards microservices because it lets them be more agile in terms of application development and reduces the time it takes to get enhancements or fixes to production. Microservices has been a boon to large enterprise applications, which are now developed by teams of geographically and culturally diverse developers.

What are the benefits of microservices?

Microservices offer a number of benefits to companies, both large and small.

1. Simplicity and agility

Applications built with microservices are easier to build and maintain because they’re split into a set of smaller, composable fragments. Code management is less painful because each microservice is a separate chunk of code. Services can be implemented with different programming languages, databases, and software environments.

2. Higher resiliency

Any problem will typically not influence the entire application or system through resiliency patterns like bulkheads and circuit breakers. When an error or failure happens in an individual microservice, it can be handled relatively quickly because it’s not affecting the entire system. Troubleshooting and fixes are handled more easily and efficiently with less downtime.

3. Autonomous cross-functional teams

Today’s companies, both large and small, often deal with geographically separated development teams. Microservice architecture grants developers more independence to work autonomously and make technical decisions more quickly without blocking others.

4. Innovation

Microservice development teams are organized around business capabilities and products, rather than technologies. This means services are adaptable for use in multiple contexts and a variety of products or business channels. Teams can innovate more easily because they have access to the best technology for the situation.

5. Scalability

As a company’s tech stack evolves into a truly hybrid environment that includes both on-premise and cloud solutions, it becomes challenging to create applications that can straddle them all. Because microservices can be developed with individual technologies, you can select the most appropriate one for your stack. You can add new components to your system more easily and scale services separately from each other. The built-in resiliency of microservice architecture means you’ll avoid overloading your system at any point while enjoying the same efficiency.

6. Higher return on investment

When using microservices, your company will enjoy a higher return on investment and a better total cost of ownership through faster development times. You’ll also be able to use a mix of hardware and software to support your applications, allowing you to save money on acquisition costs when needed.

Microservices offer a unique opportunity for companies looking to develop large applications. They’ll make development and maintenance easier, increase productivity, offer technical flexibility and scalability, and are great for distributed teams.

For those of you developing large, complex software, microservice architecture is the way to go.
