“Software is eating the world” - Marc Andreessen

Software is everywhere. Every company today depends on software to deliver its services to end users. There is a lot of pressure on companies today to move faster and be more agile, all while delivering better reliability without sacrificing security.

To Microservice or Not To Microservice Is Not The Question

Microservices are a way of breaking large software projects into loosely coupled modules, which communicate with each other through simple protocols. Microservices is a fairly familiar term, but do people understand the term fairly? It can be a fair question. I see a lot of companies approaching Opcito for consultation related to microservices architecture, and I like all the buzz around microservices.

Secure your Kubernetes clusters with RBAC

Introduction:

Kubernetes is an open-source container orchestration tool to manage applications in a clustered environment. In its latest release (version 1.6), Kubernetes introduces new features such as DaemonSet, ETCD v3, scalability updates, advanced scheduling, and improvements to Kubeadm. In addition, the new RBAC authorizer is another interesting feature of Kubernetes 1.6. Within Kubernetes, authorization happens as a separate step from authentication.

AIOps - Minority Report of IT world

Minority Report is a 2002 American science fiction film directed by Steven Spielberg. Why am I talking about movies all of a sudden? The movie had a very interesting theme where a special police unit can arrest murderers before they commit their crimes; for me, system failures, or any failure, for that matter, in IT is a crime. Even though we can’t predict the future in real life, we can at least analyze real-time data and stats to reach a conclusion and avoid or stop crime before it affects your system.

Docker’s Moby and LinuxKit - Making Containers Mainstream!

We all have been hearing about Containers for a long time now. 1979 was the year when we first saw what Unix v7 could do, and in recent times, we have been looking at Windows server containers and Hyper-V containers. Its inherent advantages, like more computing workloads with lesser hardware, made it popular, and as a result, we have witnessed the rate at which businesses have moved and are still moving their server applications to containers.

Kubernetes- Container Orchestration Redefined!

For any symphony to sound mellifluous, it is necessary to have an orchestrator to make it sound so. The same is true with containerization, as Kubernetes is turning out to be a fine orchestrator.

Creating Kubernetes Clusters on AWS using KOPS

Why Kubernetes?

Kubernetes is an open-source system for automating containerized application deployment, scaling, and management. Kubernetes has emerged as the go-to solution for all your distributed architecture queries. It groups containers that make up an application into logical units for easy management and discovery. But how do you actually provision and deploy a production-ready Kubernetes cluster while ensuring high availability?
The answer is KOPS.
