How to Install and Configure Kubectl: A Tutorial

Reading Time: 4 minutes

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.

Kubernetes uses an HTTP-based REST API which is the actual Kubernetes user interface employed to manage it. This means that every Kubernetes operation is represented as an API endpoint and can be carried out based on an HTTP-request sent to the endpoint. 

In this article, we will review Kubectl, and outline its installation, configuration, and use.

SAN VS. NAS: A Comparison

Reading Time: 4 minutes

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 Kubernetes RBAC Authorization

Reading Time: 4 minutes

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.

Starting with Kubernetes 1.6, RBAC is enabled by default and users start with no permissions, and as such, permissions must be explicitly granted by an admin to a specific service or resource. These policies are crucial for effectively securing your cluster. They permit us to specify what types of actions are allowed, depending on the user’s role and their function within the organization.

How to Set Up and Use Cloud Block Storage

Reading Time: 5 minutes

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.

Understanding Load Balancing for Web Servers

Reading Time: 3 minutes

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.
