Become a DevOps master
The aim of this roadmap is to give you an idea about the new landscape and a clear view if you are confused about what to learn next. So, recommend you to go to this link and use the article published there.
With the growth of new technology and appearing DevOps, SysOps, DevSecOps, and other words, many think that they are just like a simple word! but if you are passionate about DevOps methodology and if you want to become a developer or DevOps, you should be clear and have a good understanding about what they are. So, these roadmaps cover everything that is there to learn for the path listed below.

I faced a problem in Linux to type Persian. I installed the Persian language in setting and after changing my keyboard, I couldn’t type Farsi. After investigating many websites, I noticed that this was a horrible bug. To solve this issue, you need to run a command runner (alt+f2) and type “r“. Then, you could choose Persian language and type Farsi in your Ubuntu.
I had this horrible bug (before downgrading to 3.32) where I would start an app normally (through Super-key menu or “command runner” (alt+f2)) and every time I refreshed my session (alt+f2 –> type “r”) gnome would just kill some of my apps.
Top 26 Tools for VMware Administrators
Virtualization is one of the popular technologies that are implemented in many IT environments. to work on virtualization technologies such as VMware vSphere, Citrix Xen or Microsoft Hyper-v, there are lots of application and tools that could make you possible to manager yoru virtualized infrastructure. in this article, we are providing many tools for administrators that is challenging to keep track of them all. most of them will be very useful for engineers to manage effectively their infrastructure. you could read the article.
1. As Built Report
As Built Report is an open source configuration document framework which generates and builds documents in XML, Text, HTML, and MS Word formats using Windows PowerShell and PScribo.

Kubernetes has emerged as the leader in the container orchestration and management platforms. However, this begs a question: Who will manage your Kubernetes Infrastructure? In this course, Azure Kubernetes Service (AKS) – The Big Picture, you will learn the skills to deploy a managed Kubernetes platform on Microsoft Azure without worrying about the underlying computer and management overhead. First, you will learn the fundamentals of Docker and Kubernetes and see how it applies to a Microservices Architecture. Next, you will discover how to deploy an application to a local Kubernetes Cluster and see how that experience translates to deploying the same application to Azure Kubernetes Service without any change to the deployment experience. Finally, you will see how easy it is to scale your application workloads in AKS, which will help you take your AKS skills to the next level and help you modernize and re-platform your application workloads on Microsoft Azure. By the end of this course, you will have a foundational knowledge of Azure Kubernetes Service that will help you deploy containerized workloads on Azure with minimal management overhead.
Anyway, you could learn this course thorough the course provided by https://www.pluralsight.com/courses/azure-container-service-big-picture
Docker introduction
Docker is an open platform management tool for Linux Containers. It provides a means for developers and system administrators to build and package applications into lightweight containers. Docker consists of the following components:
- Docker Engine – A portable, lightweight runtime and packaging tool
- Docker Hub – A cloud service for sharing applications and automating workflows
Docker is used to create image-based application containers. Image-based containers package an application with the individual runtime stack into a single container. This makes the container-independent from the host operating system and kernel version. As a result, you can run the same application, unchanged, on laptops, data center virtual machines, and any cloud. You can transfer this container to another machine that runs Docker and runs the application without any compatibility issues.

Microsoft announced during this week’s Build Conference that its Azure Kubernetes Service (AKS), formerly known as “managed Kubernetes on Azure,” will reach general availability status “in the next few weeks.”
The official name change to AKS was noted by Gabe Monroy, program manager lead on containers for Microsoft Azure. He also was the former CTO of Deis, a maker of open source tools for Kubernetes, a company that Microsoft acquired last year. The name change is worth noting because Microsoft has an Azure Container Service (ACS) that also supports Kubernetes. The difference between ACS and AKS is that AKS adds automated support for upgrades and scaling capabilities, plus it has self-healing aspects, aiming to make spinning up containers on Kubernetes easier for developers
Kubernetes itself is a container orchestration service for clusters that was originally fostered by Google. Microsoft lately has been working to make Kubernetes easier to use when hosted on its Azure datacenter infrastructure. Containers are operating system virtualization solutions, largely fostered by Docker, that aim to make it easier for applications to be hosted without conflicts.
Monroy indicated that AKS is now “part of the Kubernetes Conformance Program,” a certification program run by the Cloud Native Computing Foundation that assures it can be used in different environments. He also described some new features leading up to the coming general availability milestone.
The difference between VM and Container?
One of the most interesting terms in virtualization that is appeared recently is containers. The containers offering a new layer of virtualization that are fit for packaging application. This type of virtualization allows to quickly build and deploy a large number of hosts or containers in a very short time and saves lots of time and money as compared to installing and deploying physical servers.
Virtual machine ( VM ) have been around for a few years from now while containers are new as an alternative solution to VM. If you are familiar with containers and Docker platform, we want to talk about some basic distinction of VMs and containers. In the following, there are top five difference between VMs and Containers.

From 2 years ago, I decided to take part in VMware certification. last year, I have achieved the first certificate. Subsequently, I have got familiar with the next stage to complete your understanding and knowledge on VMware technologies and therefore, starting to study for VCAP-DCV exam. I’m of the opinion that, it is more difficult than all VMware certification in VCP level. I have read many articles and blogs about VCAP and it has always been a very elusive goal. While planning to participating in the exam, you should keep in mind: Why I have to become a VCAP expert. So, I realized many engineers to show their abilities and deep experience in designing or implementing, make best use of this qualification and get achieved this certification. you can read an interesting articles written by Balyparker
