+# AWS Workspaces
+
+- Amazon WorkSpaces is a managed, secure cloud desktop as a service (DaaS).
+- Has concept of WorkDocs
+
+## Purpose
+
+## Characteristics
+
+- Each WorkSpaces instance is associated with a specific VPC and the AWS Directory
+  Service.
+- The WorkSpaces service requires a minimum of
+  two subnets to operate, each in a different Availability Zone (AZ).
+- PCoIP (port 4172) --> PC over IP
+- WSP (port 4195) --> WorkSpaces Streaming Protocol
+- Client applications use port 4172 (PCoIP) and port 4195 (WSP) for pixel streaming to the WorkSpace and ports 4172 and 4195 for network health checks
+- A WorkSpace bundle is a combination of an operating system, and storage, compute, and software resources
+
+## AWS Directories
+
+- Act as a storage for user and workspaces (computers) information.
+- Has unique registration code per directory which will be shared to all the workspace users.
+- Requires two subnets or your VPC.
+
+## Useful AWS commands
+
+```
+aws workspaces describe-workspaces
+aws workspaces describe-workspaces --output table
+aws workspaces describe-workspace-directories
+
+
+```
+
+### Cost saving or clean up after experiments
+
+```
+aws workspaces terinate-workspaces --terminate-workspace-requests <workspace id(s)>
+```
+
+## Pricing Notes
+
+- Identify less never or frequently used workspaces and decommision it
+
+```
+aws workspaces describe-workspaces-connection-status  --output table
+aws workspaces describe-workspaces --workspace-id <workspace-id>
+```
+
+To find what are the workspaces connected before/after certain time
+
+```
+aws workspaces describe-workspaces-connection-status --query 'WorkspacesConnectionStatus[?LastKnownUserConnectionTimestamp>`2023-12-15T17:55:3S.390Z`]'
+
+```
+
+Client side sort using `jq`
+
+```
+aws workspaces describe-workspaces-connection-status | jq -s 'sort_by(.LastKnownUserConnectionTimestamp)'
+```

+
+## Security
+
+- Define security group to limit the inbound and outbound traffic.
+- If your company uses HTTP proxy, VPN or Zero-Trust network setup, you may use limit the inbound client connection so that workspaces not available from public network.
+- You can limit outbound traffic with [IP range of the region](https://docs.aws.amazon.com/workspaces/latest/adminguide/workspaces-port-requirements.html#gateway_IP) on port 4195 from your corporate network to the AWS.

+## Problems and Solutions
+
+### Unauthorized DescribeUsers
+
+```
+aws workdocs describe-users --organization-id <directory-id>
+
+An error occurred (UnauthorizedResourceAccessException) when calling the DescribeUsers operation: Principal [arn:aws:iam::account:user/mahendran] is not allowed to execute [workdocs:DescribeUsers] on the resource
+```
+
+#### Solution
+
+### Reset user password
+
+- https://www.youtube.com/watch?v=bXS7iSSIWt8
+
+```
+You need permissions
+You do not have the permission required to perform this operation. Ask your administrator to add permissions.
+User: arn:aws:iam::account:user/mahendran is not authorized to perform: ds:ResetUserPassword on resource: arn:aws:ds:eu-west-1:account:directory/d-dirID because no identity-based policy allows the ds:ResetUserPassword action
+```
