The AWS Cloud spans 55 Availability Zones within 18 geographic Regions and 1 Local Region around the world, with announced plans for 12 more Availability Zones and four more Regions in Bahrain, Hong Kong SAR, Sweden, and a second AWS GovCloud Region in the US.

Region = AWS Regions provide multiple, physically separated and isolated Availability Zones which are connected with low latency, high throughput, and highly redundant networking. Each Region Consists two or more availability zones. Regions are selected  to satisfy performance requirements like low latency and to satisfy specific regulatory requirements.
Availability Zones (AZs) = Availability Zones offer AWS customers an easier and more effective way to design and operate applications and databases, making them more highly available, fault tolerant, and scalable than traditional single datacenter infrastructures or multi-datacenter infrastructures.

AWS Local Region = For customers who specifically need to replicate their data or applications over greater geographic distances, there are AWS Local Regions. An AWS Local Region is a single datacenter designed to complement an existing AWS Region. Like all AWS Regions, AWS Local Regions are completely isolated from other AWS Regions.

Edge Location = It is the location where end users are located to access services. This uses AWS CloudFront to offer the services to end users with low latency. Amazon CloudFront uses a global network of 136 Points of Presence (125 Edge Locations and 11 Regional Edge Caches) in 62 cities across 29 countries.

Be Careful!!!!! While Creating the Disk Groups in vSAN

Recently i have seen an issue in vSAN, Where i was creating the disk groups on one of the esxi host in vSAN Cluster. What i did:-
1. I selected the same esxi host in disk management and then click on create disk group icon.
2. Then selected one cache tier disk and two capacity tier disks and click on finish and task is started.
3. But before this task gets finished. I started the creation of one more disk group creation on the same esxi host with same type of configuration that i have discussed earlier  and click on finish. Task is started.
4. BUT the final output was, Only one disk group with 4 capacity disks. Although it should be two disk groups with two capactiy disks each.

So, one should be very careful while doing the same type of activity. Let the first task to be completed and then start the second task of disk group creation.

Considerations while Adding or Removing Disks from VSAN Cluster when Deduplication and Compression is Enabled

  1. You can add a capacity disk to a disk group with enabled deduplication and compression. However, for more efficient deduplication and compression, instead of adding capacity disks, create a new disk group to increase cluster storage capacity.
  2. When you remove a disk form a cache tier, the entire disk group is removed. Removing a cache tier disk when deduplication and compression is enabled triggers data evacuation.
  3. Deduplication and compression is implemented at a disk group level. You cannot remove a capacity disk from the cluster with enabled deduplication and compression. You must remove the entire disk group.
  4. If a capacity disk fails, the entire disk group becomes unavailable. To resolve this issue, identify and replace the failing component immediately. When removing the failed disk group, use the No Data Migration option.
