What is microservices based architecture?
Commonly referred to as microservices, microservices architecture is a style used to have applications created. The microservice is able to separate an application to form parts that are smaller and independent, and each having individual ability. In order for a request to be served, the application is able to request other microservices that are internal, to formulate replies.
A great example of microservice architecture is a container, which allow the user to concentrate on the services being developed and not stress over any dependent issues. Applications that are cloud will normally already be containers that use microservices.

How does a microservice work?
With it being important to know what a microservice architecture is, it is now important to know how a microservice works. Below, we´ve listed a few important parts that helps it all work.
Having Users
Many users and devices exist that help carry out a variety of tasks, such as configuring and searching. This is how the microservice architecture begins.
Providers of the Identities
After a request is obtained, it gets sent to many providers of identity. They then verify each request and share them with an API and then go on to other different services that are internal.
An API
A gateway known as an API also plays an essential role within microservice architecture. It is where requests can be made for a microservice. It is essential due to the fact that a direct service can not be requested. With the API, it is a ¨go-between¨ for both.
Formats for Messaging
More than one format for messaging exists in order for services to be communicated. These are known as a synchronous and asynchronous message. In an initial case, a client is awaiting a response from the service. As this occurs, the microservice integrates a transfer of the state that is built upon HTTP. The next involves a protocol similar to AMQP that is included, that won´t have the customers waiting to obtain a response.
A Database
A database is included with every microservice. It is updatable by way of the API it corresponds to.
Why are apps moving to microservices?
There are a few reasons why an app might move to microservices. Below are a few examples:
They Are Scalable
With each component being individual, an application can become scalable without any other components needing it. Being independent also allows a developer can have all services scaled when each is needed. This will ultimately decrease the cost of resources that every user is associated with.
Can Reach Market Faster
Because of scaling being independent for each component, a developer is not required to include a complete codebase in order to have features added or modified. Modifications are able to be completed to a service that is specific so that an app can be quickly available for market. This allows for a responsive market, which can allow for a developer to create many abilities digitally.
Can Be Maintained
The maintenance cost is a lot less when microservices are used with an app and can be managed easily. This is due to the microservice being updated then distributed with no need for a change to take place with the application. Not only that, but an individual function is attached to every microservice and every function includes a piece of the applications code. Having a piece of the code lets a developer know exactly what is going on with the code, can discover where an error occured, and correct any problem that may be affecting a microservice.
What is difference between container and microservices?
Even though both microservices and container are quite similar in nature, the two do have a few differences that need to be known.
The first difference is the fact that they are useable together or as individuals. They can also be all-inclusive within a single function. It can also mean that the service can also be many microservices and no container. The container is fully capable of having a microservice as well as the microservice containing contianers in order for functions to become easier.
Next, a few advantages and disadvantages exist among them. With microservices, the solutions they provide are more scalable and functional. This allows the service to pass over separate platforms. Plus, the microservice is able to become very light as opposed to different solution types, because of the microservice only being a piece of the main puzzle instead of needing a whole new piece.
With the container, its benefit lies in a completely different structure. This means the container contains everything within it, as well as the resources that are required are all tied in together with functions in each separate container. This allows all to be constructed in a clear manner.
Is Kubernetes only for microservices?
Although kubernetes can be used to run microservices, there are many other applications that it can be used for. A few other examples include:
Running docker containers - When you implement the right type of platform of Kubernetes, you are able to get the help you need to create the perfect environment for enhancing integrated processes, automation, and all self-service. A developer is also able to control the performance of many containers throughout an infrastructure that is either hybrid or multicloud.
