VMware vs. AWS

Written by

In my recent AWS Certified Solutions Architect exam, one of the key learning areas that I needed to master, was the change in terminology to transfer my knowledge from VMware vs. AWS. Obviously, there is no direct one-to-one mapping of the product offerings, but there are some common areas, at a conceptual level.

So, here is a table, that roughly equates the concepts to each other;

VMware concept AWS concept Comment
Virtual Machines EC2 (Elastic Compute Cloud) IaaS
vCenter SSO IAM + Directory Service
 vNet / Virtual Network  VPC, Subnet  VMware uses VLAN(s), AWS uses CIDRs
 VM on standalone host  Instance Store  When an EC2 instance is powered off,
instance store hosted VMs are deleted
 VM Template  AMI (Amazon Machine Image)
 none (needs NSX/SDN)  Security Group  This is port filtering (firewall) for a VM
 Customize OS  EC2Config  Windows OS customisation
 NFS presented storage  EBS (Elastic Block Store)  EBS backed block storage is presented to
EC2 instances for their additional storage
 vMotion / migrate  none  Not applicable for AWS
 vCenter cluster HA DRS group  Availability Zone
 Horizon DaaS Workspaces  Hosted desktops
 none  S3 (Simple Storage Service)  Object storage is file-based
 Site Recovery Manager  none  Not available or applicable on AWS
 VDP  Glacier / Storage Gateway VTL  Glacier is object/file based
 vRealize Operations / vCenter  Cloud Watch
 SpringSource / vFabric  Elastic Beanstalk /
Cloud Formation
 Log Insight / vCenter  Cloud Trail + Inspector  Log Insight also does analytics of
other data sources
 NSX  WAF  NSX is a full software defined networking
and security suite, which contains WAF.
 Power Off VM & delete  Terminate Instance
 Hot Add RAM / CPU  none  Not available on AWS
 VM properties, disks  EBS, Volumes  VMware files under VM, AWS shows all
volumes, disks and snapshots together
 DRS Resource Pool
affinity rules
Placement Group  AWS paradigm is IaaS based

There may be some questions about my opinion of these comparative conceptual terms – if so, post a comment below.
