What is Kubectl?

Kubectl is a command-line tool for Kubernetes. It allows us to execute Kubernetes operations via the API. We can use Kubectl to deploy apps, check logs as well as manage all the other resources of the cluster.

Storing data in a safe, secure, and reliable manner has always been a significant concern for those working within a distributed networked environment. In this article, we will be exploring two specific methods of managing, preserving, and archiving information. These methods include using the SAN or Storage Area Network or the NAS or Network Attached Storage protocols. Both protocols provide a networked storage solution, but the main difference is in the approach and implementation. A NAS device is usually a single storage unit, while a SAN is typically a network cluster of several devices. Sometimes both these methods are employed and combined into a single medium called a Unified SAN. 

What Is Minikube?

Minikube is the name of a software program written in Go, which can build a local Kubernetes cluster on a single host. It uses a meager amount of resources to run a mini Kubernetes deployment. Minikube is mainly used for testing purposes using different scenarios or versions of Kubernetes

What Is Istio?

Istio is an open-source service mesh that makes it easier for a team to create a network or server cluster of deployed services. Istio provides several vital services consistently across a mesh network such as:

What is a Service Mesh?

A service mesh is a layer of communication and control between applications or microservices and the network stack they typically communicate over. This layer controls communication and helps microservices share data. This service-to-service interaction is governed by logic built into the service mesh layer. Simply put, microservices are small or partial applications, or individual functions, and the network stack is the physical networking layer.

What is RBAC?

Kubernetes Role-Based Access Control or the (RBAC) system describes how we define different permission levels of unique, validated users or groups in a cluster. It uses granular permission sets defined within a .yaml file to allow access to specific resources and operations.

What is Cloud Block Storage?

Cloud Block Storage provides additional hard drive space for your Private Cloud Hosted Server with just a few clicks. The space is not pre-formatted but rather, it is a raw block device. The simplicity of providing a raw block device on the cloud means that you can mount and format the space on your server however you would like, with whatever filesystem is appropriate for your needs. This does entail a small amount of work getting the space into a usable state which we will address in this article.

Load balancing is the distribution of a workload across many nodes. In the web hosting industry, it is typically used for balancing HTTP traffic over multiple servers acting together as a web front-end. For the sake of this article, we will focus on the balancing of HTTP and HTTPS traffic through a Zeus Load Balancer.
