Microservices Training in Chennai - Online

Micro-services are simply a service-oriented architecture pattern. Collection of various smallest independent service units are apps. Simply we can say that it is a software engineering approach. It will focus on decomposing an apps into single-function modules. This single-function module will have a well-defined interface. These modules can freely deploy and operated by small teams. These teams will be one who own the entire lifecycle of the service.

“Micro” means the sizing of a micro-service. It must be manageable by a single development team. In general, this team will consist of 5 to 10 developers. This method is useful in dividing big apps. We can divide big apps to smallest independent units.

Micro-service Architecture is a constructive development style. It allows you in building an apps. Apps are built as a collection of small autonomous services. These services generally developed for a business domain.

Let us look out with an example of e-commerce app. This app will develop with the micro-service architecture. Each micro-service will focus on single business skill. Search, Rating & Review and Payment each have their instance (server) and communicate with each other.

Let us consider the Monolithic Architecture as the best example. In this Architecture, we will join all the components of the single module. But in Micro-services we will divide them into the single modules. The Single modules are otherwise known as the micro-service. Generally, these micro-services will communicate with each other.

The contact between the micro-services is a simple way. It is a stateless contact. Each pair of requests as well as response is separate. The contact of the micro-services will be very effortlessly. In the Micro-service Architecture, the Data will organize. Each of the micro-service have its own data store in separately.

Following are the challenges in the micro-services. They are,

• Micro-services rely on each other. They will communicate with each other.
• Let us have a comparison with monolithic systems. There are more services to monitor. This will develop with the help of different programming languages.
• It is a distributed system. It is an inherently complex model.
• Here different services will have its separate mechanism. This will be resulting in a large amount of memory. This is generally for an unstructured data.
• Effective management and teamwork required to prevent cascading issues.
• Reproducing a problem will be a difficult task. It’s gone in one version. The final output will come back in the latest version.
• Independent Deployment will complicate with the Micro-services.
• Micro-service architecture brings plenty of operations overhead.
• It is difficult to manage the apps. It is difficult when we add new services to the system.
• A wide array of skilled experts will require. This will be helpful in supporting. This will require for a confused distributed micro-service.
• Micro-service is costly. In different business tasks you need to maintain different server space.
