Streamline Micro-services | Kubernetes

Introduction

The way we execute micro-services was streamlined by containers and orchestration systems such as Kubernetes. The idea was popularized by container technology as it allowed various parts of the applications to be run and scale in self-contained units with their runtime.

Micro-services and The Related Problems

The architecture of micro-services allows for more comfortable supply by reducing the transition to smaller modules, enhancing the device durability, simplifying monitoring, and independently scaling parts of the application. Micro-services are a nightmare for security and management, as you now have numerous moveable components, each catering to unique features, instead of using a monolithic framework.

Management and Security Concerns

Hundreds of micro-services connections can be used for a comprehensive app, and you’ll quickly find stuff excellent. Your protection and technical staff will ask you the critical questions like How do we ensure the contact is protected between the micro-services?

We need to guarantee hundreds of smaller providers, rather than one monolithic program. How can we separate the micro-service to address the issue in the event of a crisis?

How can a limited amount of traffic be checked so the public can gain confidence? How can we consolidate app logs when they are already distributed around many locations? How do we track resources’ health? The process of device management has become more complex, with more components creating the program.

Although Kubernetes tackles some operational problems, it can be an orchestration tool for containers, and this is fantastic. 

It does not fix problems with the architecture of micro-services yet has another function. Management resources are not the competence of Kubernetes and thus may not respond to them all by nature.

By design, the connectivity between Kubernetes containers is unsecured, and it is not easy to incorporate TLS between pods so that you would manage hundreds of TLS certificates. The identification and access control between communication pods do not apply.

There are items of Kubernetes Ingress that provide a layer 7-based reverse proxy but provide nothing more. Kubernetes delivers various ways to use the pods and to do A / B monitoring and canary deployments. Moreover, replicas of containers can be applied to do that. 

Kubernetes, in combination with Istio

Hence to take the maximum advantage, it is advised to use Kubernetes with Istio. Istio is the application for utility mesh that links, secures, manages, and manages networks.

Each micro-service is independently operating in containers when operating a micro-service program. Consequently, they have a lot of experience. You can discover, allow, and monitor certain interactions through a service mesh, often using a side-car proxy.

Take a standard example of an application with Kubernetes front end and back end. Kubernetes has an automated service finding between Kubernetes and Core DNS systems. So, you can use the service name from one Pod to the next.

But how these connections work and what you do with runtime traffic will not be much undercharged. It injects a side-car container into your pod, which serves as a proxy and interacts with your main container through the other container’s proxy.

You can now manage traffic and capture data like the proxy, so all requests go through the proxy. You can also encode communication between Pods by using a single control plane, implementing identity protection and access management.

Istio handles traffic and establishes routing rules for managing traffic and identifying connections between services because of a side-car proxy (also known as a receiving proxy) and Ingress and Egress gateways.

It helps to shield you from attacks by people in the center by offers encryption of traffic between Pods out of the box. This ensures that the front end and the back end can be jointly authenticated, and only the front end can attach to the back end. Just the front end of the backend and vice versa, because nothing can do something for the program’s entirety if one of the Pods is hacked.

It helps protect against midway attacks by providing the encryption of traffic between Pods out of the box. In other words, the front end and the back end can be authentically mutually validated and only the front end can be connected to the back end. The backend always depends on the front, but no one can do something about the residual program if one of the Pods is affected. Istio also offers features that control access to the cluster by fine-grained rules and uses auditing capabilities that Kubernetes does not have.

Conclusion

Using services such as Kubernetes allows your operations to be streamlined and consolidated, owing to more outstanding management and sustainability across the board.
