Microservice kubernetes communication architecture

What is Microservice based architecture?

Microservices – also known as the microservice architecture – is an architectural style that structures an application as a collection of services that are. Highly maintainable and testable. Loosely coupled. Independently deployable. Organized around business capabilities.

How Microservices can communicate with each other?

The most common type is single-receiver communication with a synchronous protocol like HTTP/HTTPS when invoking a regular Web API HTTP service. Microservices also typically use messaging protocols for asynchronous communication between microservices .

What is Microservices in Kubernetes?

Kubernetes is an open source orchestrator for deploying containerised applications ( microservices ). It is also defined as a platform for creating, deploying and managing various distributed applications. Kubernetes provides the software necessary to build and deploy reliable and scalable distributed systems.

What is the architecture of Kubernetes?

Kubernetes Architecture and Concepts From a high level, a Kubernetes environment consists of a control plane (master), a distributed storage system for keeping the cluster state consistent (etcd), and a number of cluster nodes (Kubelets).

Is Kubernetes a Microservice?

Microservices do not necessarily have to be containerized. Similarly, a monolithic application can be a microservice . Kubernetes is a great platform for complex applications comprised of multiple microservices . Kubernetes is also a complex system and hard to run.

Is REST API a Microservice?

Microservices : The individual services and functions – or building blocks – that form a larger microservices -based application. RESTful APIs : The rules, routines, commands, and protocols – or the glue – that integrates the individual microservices , so they function as a single application.

Should a Microservice call another Microservice?

The implementation of a microservice might seem easy in the beginning. You should , therefore, try to avoid any dependencies between the services and implement them as independent as possible. But you can’t always do that. You sometimes need to call another service to trigger its business logic.

How many endpoints should a Microservice have?

The number of endpoints is not really a decision point. In some cases, there may be only one endpoint , whereas in some other cases, there could be more than one endpoint in a microservice. For instance, consider a sensor data service, which collects sensor information, and has two logical endpoints–create and read.

Can a Microservice have multiple APIs?

With the above example, you can probably see that a microservice is capable of being more than just an API for a system. An entire application can encompass a series of microservices that use their own APIs for communication with each other.

What is Kubernetes vs Docker?

A fundamental difference between Kubernetes and Docker is that Kubernetes is meant to run across a cluster while Docker runs on a single node. Kubernetes is more extensive than Docker Swarm and is meant to coordinate clusters of nodes at scale in production in an efficient manner.

How Docker is used for Microservices?

With Docker , you can make your application independent of the host environment. Since you have microservices architecture, you can now encapsulate each of them in Docker containers. Docker containers are lightweight, resource isolated environments through which you can build, maintain, ship and deploy your application.

Why do we need containers for Microservices?

Containers and microservices enable developers to build and manage self-healing microservice -based applications more easily. Containers encapsulate discrete components of application logic provisioned only with the minimal resources needed to do their job.

What is Kubernetes in layman’s terms?

“ Kubernetes , or k8s, is an open source platform that automates Linux container operations. “In other words , you can cluster together groups of hosts running Linux containers, and Kubernetes helps you easily and efficiently manage those clusters.”

Who started Kubernetes?

Kubernetes (κυβερνήτης, Greek for “helmsman” or “pilot” or “governor”, and the etymological root of cybernetics) was founded by Joe Beda, Brendan Burns, and Craig McLuckie, who were quickly joined by other Google engineers including Brian Grant and Tim Hockin, and was first announced by Google in mid-2014.

Is Kubernetes a server?

You can say that Kubernetes /OpenShift is the new Linux or even that “ Kubernetes is the new application server .” But the fact is that an application server /runtime + OpenShift/ Kubernetes + Istio has become the “de facto” cloud-native application platform!
