Introduction To Microservices

There has been a rapid development in the application development industry in order to keep pace with the technological advancements and to meet customer requirements. However, while working with the traditional developments, people had to use large chunks of code. This made the entire task difficult as people had to go back to square one to resolve a minute problem. 

Today, to solve this issue, most applications are constructed by assembling several mini-applications, each of which constitutes a particular functionality. This form of assembling tiny applications to make one system work is called microservice architecture. To help you with the microservices, you can hire a reliable PPC company

Before you start hiring or looking for a microservice provider, it is essential to know the basics of microservices. So, let us dig deep into the mechanism of microservices. 

What is a microservice?

Microservice, also known as the microservice architecture, is a system that develops an application by selecting and gathering a few individual services to impart a responsive and highly seamless performance. For better understanding, let’s consider an example here. If you are creating a web application based on the microservice architecture, you divide the whole coding part into separate functionalities. Thus, you develop and deploy each part as a separate app. 

Many of you may consider the microservices as similar to monolithic architecture. However, there is a slight difference between the two. While the monolithic architecture merges everything and depends on the whole process on a single entity, the microservice architecture divides the whole function into multiple modules consisting of autonomous components. 

How do microservices function?

Once you have decided on the structure of the web app, now you have to figure out how you will divide it into separate entities to ensure that all of them come together and produce a harmonious service. Also, you have to keep in mind to use something that enables faster, direct, and flawless communication. APIs can well achieve this. 

API or Application Programme Interface is an access point through which each modular functionality interacts. The microservice uses these APIs to send, receive and respond to queries and requests from the other modules. Therefore, each module must have a specific API. This will make all the modules accessible for queries. Furthermore, each API has to have a clearly defined and distinct endpoint to seek accurate information and make it work thoroughly. 

How different is Microservice Architecture from Traditional Architecture? 

To understand how different the microservice architecture is, it is essential to compare it with a traditional or monolithic architecture. As the name suggests, monolithic architecture is based on a single application. This means that all the functionalities in this structure rely on one structure, use the same file, communicate with the same server, and are deployed on the same machine. 

With the monolithic architecture, you will not need much time to create applications as only the essential features must be built, later added under a single functionality. Therefore, the monolithic architecture does not use APIs. 

On the contrary, the microservice architecture imparts the flexibility of dividing the functionalities and working on them individually. Besides, the functionalities used in the microservice can be reused. So, you can apply these modules to other applications as well. Moreover, since the microservice architecture is flexible, they are resilient to changes. So, even if learning the coding of microservices is a bit complex, you can manage it once you get into the subject matter. 

Benefits of microservice architecture 

These days, the microservice architecture is used by most app developers for various reasons. Here are the benefits of microservice architecture that you can avail of: 

  • Highly flexible 

Since each microservice module works independently, the developers or programmers can use different platforms or languages to build these modules. The seamless communication from one module to another is propagated via APIs. 

  • Functional modules are reusable 

The features facilitated by the microservice architecture allow developers to reuse these functional modules and apply them in different web apps. When you use already refined microservices, you save a lot of resources and time. 

  • Adopts changes quickly 

The flexibility makes the microservice architecture different from traditional or monolithic architecture. Since the functionalities are not dependent on one another, developers can modify them according to their needs. 

  • Scalable 

The microservice architecture features scalability. This means you can measure the progress that occurs by using this model. You can scale only those resources that you have used. 

  • Faster development cycle 

When the modules in your system are distributed, updates can be easily captured. Also, this enhances the development cycle. Therefore, one of the most significant benefits of microservice is the faster development cycle. 

  • Transparent model 

In a microservice architecture, none of the employees will have difficulty understanding and modifying its codes. Managing one microservice module is more accessible than handling all ten accumulated under one entity. 

Conclusion 

So, when deciding on the architecture for developing a web app, consider the type of application you want to create. However, if you want your web app to stay updated, the microservice architecture can be a good choice.
