VMware is a prominent virtualization and cloud computing software. This software was initially developed in 1998 and is now owned by Dell Technologies. It offers numerous features such as virtualization, networking, security management, and storage. It also allows you to govern your feature set and connect with the cloud.
VMware allows you to run and operate multiple OS, along with their different versions. You can run Windows, Linux, and NetWare on a single machine without repartitioning or rebooting it. VMware does this by generating an abstraction layer over a computer’s hardware.
VMware provides its users with advanced server management features. You can execute up to 70,000 virtual machines across 15 vCenter servers. VMware uses a centralized platform for executing vSphere environments across hybrid clouds. You can also automate features for your virtual infrastructure and server administration.
Hiring Guide
VMware enables the hardware components of a computer such as memory and storage to be segregated into multiple virtual computers. You can create new servers and libraries with pre-configured features (firewalls, security patches, software) and use them for different devices without affecting system performance.
You can run and test various applications using VMware since each virtual machine has its own memory CPU and I/O. Collaboration with other engineers and testers is easy as you can connect multiple virtual machines through virtual network segments. You can also use VMware to emulate test conditions such as bottlenecks.
Relevance of VMware in today’s industry
VMware is a trusted name in virtualization services. It has an amazing design, excellent community features, and an easy-to-use interface. Analysis companies like Forrester, Gartner, and IDC recognize this software as a premier virtualization solution. VMware serves over 500,000 customers worldwide.
VMware reduces data center expenses, decreases downtime, and improves the efficiency of existing infrastructure. It allows companies to extend their server capacity without increasing the number of physical computing devices. It also reduces the hardware required for testing and deploying applications. As a result, VMware is a great way to boost ROI and help in cost reduction.
Issues companies have while hiring VMware engineers.
One of the significant issues with hiring VM engineers is that some of them only possess theoretical knowledge of the subject. They lack a practical approach to virtualization and don’t know what this job actually implies.
OS crash and graphical mismatch errors are 2 of the most common issues with virtual machines. Any engineer who wants to work with VMware should know how to handle these issues, along with their regular deployment and maintenance.
Engineers who work on virtual machines have to constantly update their VMware stack. Without it, options like restart and shutdown won’t work cleanly. They also need to update and maintain VMware network devices, i.e., the devices that facilitate networking for VMware. VMware memory limits must also be set up manually by VMware admins. Doing this requires technical expertise and knowledge, along with a solid understanding of hardware and software stack.
How to select the perfect VMware engineer?
A good VMware engineer should have deep knowledge of the platform along with an understanding of VM solutions such as vSphere, ESXi, and VMware Player. They should also know about Kubernetes and Docker.
The candidate should have expertise in object-oriented design and multi-threaded programming. In addition, they must have experience in network programming and cross-platform development for different operating systems such as Windows, Linux, iOS, and Android.
The selected engineer should also be well-versed in reverse engineering using kernel and user mode assembly code. Candidates with an understanding of AWS, resource management, and Terraform Languages are always a great addition, mainly because VMWare instances will have to integrate with multiple components across digital environments.
Interview Questions
State differences between VMware and Virtual Box.
Oracle’s Virtual Box offers both hardware and software visualization, while VMware only offers hardware visualization. The snapshot feature isn’t available for the free version of VMware but it is available in Virtual Box. In addition, Virtualbox can’t run on macOS while VMware can.
VMware is free for personal use, while Virtual Box is an open-source tool.
What do you understand about the VMware Workstation?
VMware Workstation is a desktop hypervisor that can run virtual machines, Kubernetes clusters, and containers. It’s free version is Workstation Player and the paid version is called Workstation Pro.
VMware Workstation runs on modern x64 CPUs and creates isolated and secure virtual machines. In addition, it comes with a host of extra components called VMware tools that provide the functionality for the hardware emulation.
What are the different virtualizations available through VMware?
VMware offers 5 different visualization options for its customers. They are desktop virtualization, application virtualization, server virtualization, storage virtualization, and network virtualization.
What is vSwitch?
vSwitch or virtual Switch is the virtual networking switch that connects virtual machines through an ESXi host. They also provide network supervision, migrations, and security services to virtual machines.
There are 2 types of vSwitch: standard virtual switches and distributed virtual switches. They are deployed and monitored by VMware NSX. Each vSwitch has 128 ports.
Define hypervisor and its types in VMware
Hypervisor refers to a virtualization layer that allows multiple operating systems to divide one hardware host through virtualization. It’s software that can create and run virtual machines on your system. There are 2 kinds of hypervisors: hosted and bare metal.
Hosted hypervisor- This hypervisor works as a software layer on the existing operating system.
Bare-metal hypervisor- This hypervisor is installed directly onto the hardware and acts as a lightweight OS.
