VMware backups vs snapshots: what freshers get wrong (VMware for Beginners, Part 14)
A snapshot is a save-point that depends on the original VM; a backup is an independent copy stored somewhere else. Mix them up and you can lose data. Here is the difference, in plain English, with a home-lab task and a real interview question.
-
Create and manage a virtual machine in vSphere, step by step (VMware for Beginners, Part 13)
The seven-page New Virtual Machine wizard takes two minutes; the choices inside it take judgment. How to size, provision, install, and manage a VM the right way from day one.
-
Resource management in vSphere: shares, limits and reservations (VMware for Beginners, Part 12)
Shares, limits and reservations decide which VM wins when an ESXi host runs short. Here is what each control really does, the defaults that trip up freshers, and how to set them without hurting performance.
-
vSphere HA: what happens when an ESXi host dies (VMware for Beginners, Part 10)
vSphere HA restarts your VMs on another host when an ESXi host fails. A plain-English guide to how HA detects a dead host, what admission control does, and why it is not zero downtime.
-
vMotion: moving a running VM with zero downtime (VMware for Beginners, Part 9)
vMotion moves a powered-on VM between ESXi hosts with no downtime a user can feel. Here is how the live memory copy works, what it needs, and how to explain it in an interview.
-
Templates, clones and snapshots in VMware, made simple (VMware for Beginners, Part 8)
Snapshots are short-lived save points, templates are reusable master images, and clones are one-off copies. What each does, when to use it, and the snapshot mistake that quietly fills datastores.
-
Virtual networking basics: vSwitch, port groups and VLANs (VMware for Beginners, Part 7)
A plain-English guide to VMware virtual networking for freshers: what a vSwitch, port group, uplink and VLAN really are, how a packet travels from VM to physical switch, and the VLAN and port-group mistakes that break a VM network.
-
Datastores and storage basics: where your VMs actually live (VMware for Beginners, Part 6)
A plain-English guide to VMware datastores: what VMFS, NFS and vSAN are, how a VM lives as files on disk, and why thin provisioning is the storage choice most likely to page a junior engineer.
-
What vCenter actually does (VMware for Beginners, Part 4)
ESXi runs your VMs, but vCenter Server is the control room that manages every host from one screen and powers vMotion, HA, and DRS. A plain-English guide for freshers, with the setup gotchas nobody warns you about.
-
ESXi, the hypervisor that runs your VMs (VMware for Beginners, Part 3)
A plain-English tour of VMware ESXi: what the hypervisor is, the VMkernel inside it, Type 1 versus Type 2, how you manage a host, and the boot-media trap that catches beginners.
-
Physical server or virtual machine: what really changes (VMware for Beginners, Part 2)
A plain-English look at how a virtual machine differs from a physical server, why companies consolidate onto fewer hosts, and the oversubscription metric every fresher should learn first.
-
What virtualization is, and why every company runs on it (VMware for Beginners, Part 1)
Virtualization in plain English: what it is, how one physical server safely runs many machines, and why nearly every company you will work for runs on it.
