What are Microservices?

Microservices

Microservices, or rather the microservice architecture is a system used to produce an application, built on a selection of individual services working together to ensure seamless and highly responsive performance.

If you should be building a web application utilizing the microservice architecture, you divide it into individual functionalities, developing and deploying each as a different app.

As opposed to monolithic development, where everything is merged and, therefore, dependent on each other, the microservice architecture contains multiple modules of autonomous components. It's a form of architecture depending on the system of loose coupling.

The difference between monolithic architecture and microservices architecture

To obtain a better knowledge of microservices, let's compare them to the system used prior with their development – monolithic architecture.

Monolithic architecture worked fine for traditional server-side systems. They're systems based on the same application. All the functionalities reside in one single structure, utilize the same file system, communicate with exactly the same server, and are eventually deployed on a single machine.

This sort of architecture allows developers to create applications faster, as they only have to build the essential features to which they'd later add-on other functionalities. Also, the performance was faster as the procedure doesn't involve APIs.

With the expansion of web applications came the requirement for agility and consistent uptime. Monolithic architecture had a lot of obstacles to match these demands.

Advantages of Microservices

The introduction of microservices solved many conditions that monolithic development could not.

1. Highly Flexible

First, the microservice architecture is highly flexible. Each microservice is independent so programmers can build modules using different languages or platforms. These modules will have the ability to communicate with one another as a result of APIs.

2. Reusable Functionality Modules

By this feature it allows developers to reuse functionality modules and apply them to other applications. Utilizing already refined microservices saves company resources, and lets developers give attention to other projects.

3. Resilient to Changes

Another significant feature is that the system is fairly resilient to changes. Loosely coupled, the functionalities within an app aren't as codependent. Developers can add new features or modify existing ones. They alter the code of 1 module instead of the entire application.

4. Scalable

Unlike monolithic apps, microservices are excellent for scaling. They make fully sure your application is up and running constantly, without wasting hardly any money on unused modules. When you deploy functionalities on different servers, the system enables you to scale only the resources needed.

5. Faster Development Cycles

In a distributed model, the app is broken into smaller services. If your organization has adopted agile development, your teams can easier update it and accelerate development cycles.

From a business perspective, faster development cycles are one of many greatest improvements introduced by microservices.

6. Transparent Model

New employees, for instance, will easier understand and modify the code. This builds upon the information that the app is distributed among various services. Handling one microservice at the same time is simpler than tackling a whole integrated system.

Drawbacks of Microservices

1.Complexity

The main drawback of microservice architecture is its complexity. Compared to monolithic applications, the newly developed system consists of various components. These components (microservices) need to work flawlessly on their own and in the system.

2. Expenses

This technique is also more expensive. Because services are deployed on multiple servers, the application form ends up requiring a more significant quantity of CPUs and more runtime environments. Furthermore, because of their importance of constant communication, microservices make many remote calls. These and other factors mount up, thus requiring an expanded budget for development.

3. Security

Microservices also require higher security measures. As previously mentioned above, services talk together via APIs. This implies they exchange information over the network, that will be always a potential threat. Because of this, maintenance and upgrades have to be impeccable.

4. Performance

The complexity of the architecture also affects its performance. As microservices include multiple JVM (Java Virtual Machine) instances and inter-process communication, their efficiency could be slower than with monolithic apps.
