Working with Persistent Volumes in Kubernetes

The main reason behind containerization is to allow microservices to run in a stateless way. A container will receive provisioned cloud resources, perform its tasks, and then be destroyed as soon as the process is over. There are no traces of that container or tied up cloud resources to worry about. This was what has …

Cost‌ ‌Optimization‌ ‌on‌ ‌AWS‌ ‌EKS‌ ‌Clusters‌

Containerization and modern cloud infrastructure have made it possible to deploy even the most complex applications without making big initial investments. With most cloud computing models, you pay fixed fees only for the resources you use, and you are all set. Scaling up (and down) becomes easier too since you are not actually investing in …

How to Create Your Own Kubernetes #CustomResources

How to Create Your Own Kubernetes Custom Resources

As a platform for managing containerized services and workloads, Kubernetes is incredibly modular. Modularity is more than just a theme; even controllers and resources that are native to Kubernetes are now being built as custom resources and controllers, all for the sake of expanding the platform’s modularity to the next level. Of course, Kubernetes custom …

A Kubernetes Service Mesh Tool Comparison for 2020

A Kubernetes Service Mesh Tool Comparison for 2020

Service mesh is not a new concept, but its implementation for connecting microservices running on top of Kubernetes as a containerization platform makes the idea of having a service mesh more popular. Without a service mesh, each microservice needs to be configured to accept (and send) connections to other microservices it needs to communicate with. …
