Tag: Virtualization

With the increased digitization of everyday life and broader adoption of cloud computing, virtualization has become one of the pillars of today’s Internet. Virtualization technology enables us to create virtual instances or virtual machines of operating systems, networks, and virtualized storage devices, significantly automating and simplifying IT processes, improving scalability, and significantly decreasing costs. Overall, it enables us to reduce the amount of used physical resources/servers by separating various processes onto multiple, customizable virtual machines.

Virtualization as a concept is experiencing more utility in recent times due to its ability to offer improved efficiency and scalability while reducing costs. Over 90% of businesses use server virtualization, and more organizations have begun exploring other types of virtualization, including desktop, application, and storage virtualization.

What is Virtualization?

In computing, virtualization is the method of creating a software-based instance of a specific tool that is typically physical. The kinds of tools one can virtualize are:

Virtualization is the go-to solution for organizations looking to maximize the performance of their available resources without increasing the associated costs. The ability to create and run one or more virtual instances of software applications or hardware-like servers and networking devices increases IT departments’ flexibility and ability to scale infrastructure based on business needs.

Different business and development workloads call for more versatility in your environment. Virtualization provides an option for creating virtual environments to host, test, and develop your mission-critical projects.

Introduction

As firms advance towards a more modern infrastructure, the Desktop-as-a-Service (DaaS) model is becoming an increasingly popular cloud-based system. Desktop-as-a-Service is a multi-tenant, cloud computing solution in which a service provider furnishes a virtual desktop to an end-user over the internet. A provider typically manages the infrastructure, including the security updates, available desktop applications, data storage, and backups. In specific instances, DaaS users manage these services individually. According to Gartner via Workspot:

Cloud computing is a model for empowering users to access a useful, network-accessible, shared pool of resources that allows for quick changes to settings and configurations with minimal intervention from a service provider in an easy-to-maneuver self-service management interface.

Introduction

In this tutorial, we will learn how to install and configure VMware ESXi. The majority of VMware cloud product installations are targeting experienced Linux or Windows administrators. However, we will try to simplify the process as much as possible. If you are new to hypervisors like ESXi or VMware vSphere, this guide might be right for you! Let’s start by reviewing what ESXi is.

What is a Secret? 

A Kubernetes Secret is an object that enables us to store and manage sensitive information. A Secret can contain data like SSH keys, OAuth data, or other user authentication information like passwords. It is typically stored within a cluster in a manner native to Kubernetes. Using a Secret object provides more granular control over how highly sensitive data is used. It also lowers the risk of data exposure to unauthorized parties. 

What is KubeKey?

KubeKey is the newest Kubernetes installer for KubeSphere. KubeSphere is a distributed OS management system for cloud-native applications using Kubernetes as its kernel. It provides a plug-and-play structure for seamless integration of many third-party applications. It is somewhat similar in nature to MiniKube for installing Kubernetes.
