Microservices is the Future

Microservices Architecture

Microservice architecture is one of the most discussed software architecture trends at the moment, and it has forever changed the way enterprise applications are built. Rather than the slow, complex monolithic approach of the past, developers and companies everywhere are turning to microservices architecture to simplify and scale their structures. In fact, even companies like Amazon, Netflix, Spotify, and Uber have made the transition.

Whether you want to get started with Microservices or you’re just curious about the debate surrounding it, you’re in the right place. Today, I will walk you through everything you need to know about Microservices, from real world examples to architecture patterns and more. We will cover the following:

What is Microservices Architecture?

There is no universal definition of the term microservices. The simplest definition of microservices, also called microservice architecture, is an architectural style that structures an application using loosely coupled services. These collections or modules can be independently developed, deployed, and maintained.

They operate at a much faster and reliable speed than the traditional complex, monolithic applications. Using microservice architectures, an organization of any size can evolve technology stacks tailored to their capabilities.

There are many tangible benefits to using microservices, which we will discuss later, but there is still some controversy over whether or not companies should switch from a monolithic to microservices architecture. Let’s examine the difference between the two to understand the debate.

Monolithic vs. Microservices

The monolithic architecture is the traditional way of building and deploying applications. This structure is based around the concept of a single, indivisible unit, including the server side, client side, and database. All facets are unified and managed as a single unit and codebase. This means that any updates must be made to the same codebase, so the whole stack must be altered. As monolithic applications scale, they can become quite complex, so the overall development is generally longer.

A microservices architecture, on the other hand, breaks down that unit into independent ones that function as separate services. This means that every service has its own logic and codebase. They communicate with each other through APIs (Application Programming Interfaces).

So, which architecture should you choose? Let’s break it down.

Choosing a monolithic architecture

• If your company is a small team. This way you don’t have to deal with the complexity of deploying a microservice architecture.
• If you want a quicker launch. Monolithic architecture requires less time to launch. This system will require more time later on to update your system, but the initial launch is quicker.

Choosing a microservices architecture

• If you want to develop a more scalable application. Scaling a microservices architecture is far easier. New capabilities and modules can be added with much ease and speed.
• If your company is larger or plans to grow. Using microservices is great for a company that plans to grow, as a microservices architecture is far more scalable and easier to customize over time.

Benefits and drawbacks of microservices

There are a number of reasons why a microservices architecture is a better choice for your company. Let’s discuss the most notable benefits and then examine some of the drawbacks.

Benefits

Improves Scalability and Productivity

Large teams often have to work together on complex projects. With microservices, projects can be divided into smaller, independent units. This means that teams can act independently regarding domain logic, which minimizes the coordination and effort. On top of that, the teams responsible for each microservice can make their own technology decisions depending on their needs.

For example, the internal structure of each unit or container does not matter as long as the interface functions correctly. Therefore, any programming language can be used to write a microservice, so the responsible team can select the best language for their teammates.

Integrates well with legacy systems

Monolithic systems are hard to maintain. Many legacy systems are poorly structured, poorly tested, or depend upon outdated technologies. Luckily, microservices can work alongside legacy systems to improve the code and replace old parts of the system. Integration is easy and can solve many of the problems that make monolithic systems something of the past.

Sustainable development

Microservice architectures create systems that remain maintainable in the long run since the various parts are replaceable. This means that a microservice can easily be rewritten without compromising the whole system. As long as the dependencies between microservices are managed appropriately, changes can easily be made to optimize team needs and performance.

Cross-functionality

Microservices are best for distributed teams. If you have teams around the world or various divisions, microservices grant the necessary freedoms and flexibility to work autonomously. Technical decisions can be made quickly that integrate with other services in a flash. Cross-functionality has never been easier.

Drawbacks

Deployment requires more effort

The operation of a microservice system often requires more effort, since there are more deployable units that must each be deployed and monitored. Changes to interfaces must be implemented so that an independent deployment of individual microservices is still possible.

Testing must be independent

Since all microservices must be tested together, one microservice can block the test stage and prevent the deployment of the other microservices. There are more interfaces to test, and testing has to be independent for both sides of the interface.

Difficult to change multiple microservices

Changes that affect multiple microservices can be more difficult to implement. In a microservice system, changes require several coordinated deployments.
