Amazon Web Services (AWS)

Here’s an example of a bash script that lists the active directories in an AWS account using the AWS CLI:

#!/bin/bash

# Set the AWS CLI region
aws configure set default.region us-west-2

# Get a list of all the active directories in the AWS account
active_directories=$(aws ds describe-directories --query 'DirectoryDescriptions[].Name' --output text)

# Loop through the list of active directories
for directory in $active_directories; do
  # Print the name of each active directory
  echo $directory
done

In this example, the AWS CLI is used to retrieve a list of all the active directories in the AWS account, and the bash script loops through that list, printing the name of each active directory. You can modify this script to fit your specific needs, such as filtering the list of active directories based on certain criteria.

To enable Local Zones using bash, you can use the AWS CLI and write a bash script to automate the process. Here’s an example of how you can enable Local Zones using bash:

#!/bin/bash

# Set the AWS CLI region
aws configure set default.region us-west-2

# Get a list of Local Zones in the region
local_zones=$(aws ec2 describe-local-zones --output-text)

# Enable LAX Local Zones
aws ec2 modify-availability-zone-group \
  --region us-west-2 \
  --group-name us-west-2-lax-1 \
  --opt-in-status opted-in

# Confirm that the Local Zones have been enabled
enabled_local_zones=$(aws ec2 describe-availability-zone-group-configs --zone-group-name "group_name" --query 'AvailabilityZoneGroups[].Platforms[].Value' --output text)
echo "Enabled Local Zones: $enabled_local_zones"

In this example, replace “group_name” with the name of your availability zone group. This bash script will loop through all the Local Zones in the region, enable each one, and then display a list of all the enabled Local Zones. You can run this script on a server or your local machine to automate the process of enabling Local Zones.

Amazon AppStream 2.0 in AWS GovCloud (US) is a fully managed, secure application streaming service that allows you to stream desktop applications from AWS to any device running a web browser, without rewriting them.

In Amazon AppStream 2.0, image management refers to the process of creating, maintaining, and deploying images that contain the applications and configurations needed to run your streaming sessions.

An image in AppStream 2.0 is a collection of software components and settings that are used to launch a virtual machine. The virtual machine provides the computing environment for your users to access and run their applications. You can customize your images to include the specific applications, settings, and configurations that you need.

To manage images in AppStream 2.0, you can use the AppStream 2.0 console or the AWS CLI. The console provides a graphical interface for creating and updating images, while the AWS CLI provides a command-line interface for automating image management tasks.

When creating an image, you can specify the base image, operating system, and software components to include. You can also configure settings such as the default browser, network settings, and user accounts. After you have created your image, you can update it as needed to reflect changes in your applications and configurations.

In addition to creating and updating images, you can also manage the images that are stored in your AppStream 2.0 image library. You can organize images into image categories, view image metadata, and delete images that are no longer needed.

Overall, image management in Amazon AppStream 2.0 allows you to create, configure, and deploy customized images that are optimized for your streaming sessions. By managing your images effectively, you can ensure that your users have access to the applications and configurations they need to be productive.

This article provides information on how to administer your Amazon AppStream 2.0 images. The available images are listed in the Image Registry and are categorized as public, private, shared with others, and shared with me. The article provides instructions on how to delete a private image, copy an image to another AWS region, share an image with another AWS account, stop sharing an image, keep the image up-to-date, manage Windows updates and antivirus software, and programmatically create a new image. The article also provides instructions on how to add or update image sharing permissions for an image you own.

This article describes a step-by-step guide for automating the deployment of Amazon AppStream 2.0 images to existing fleets. The process involves creating an IAM policy, IAM role, AWS Lambda function, AWS Step Functions state machine, and Amazon EventBridge rule. The IAM policy and role provide the necessary permissions for the Lambda function to manage the image update process. The Lambda function checks the key-value of tagged AppStream 2.0 resources and starts the image update process. The state machine deploys the image and any scaling actions during the defined maintenance window. The EventBridge rule triggers the Lambda function every time an AppStream 2.0 resource is tagged. The process notifies administrators of the image deployment status using Amazon Simple Email Service.

This article explains how to use Active Directory with Amazon AppStream 2.0. You can join the Always-On and On-Demand Windows fleets and image builders to domains in Microsoft Active Directory and use AWS Directory Service for Microsoft Active Directory to create an Active Directory domain. By joining AppStream 2.0 to your Active Directory domain, you can access Active Directory resources, use Group Policy settings, stream applications that require authentication, and apply enterprise compliance and security policies. Currently, Linux fleets and image builders do not support domain join.

https://docs.aws.amazon.com/appstream2/latest/developerguide/autoscaling.htm

Fleet Auto Scaling for Amazon AppStream 2.0 allows users to adjust the size of their AppStream 2.0 Mas-On or On-Demand fleets to match the supply of instances to user demand. The size of the fleet determines the number of concurrent users who can stream. Fleet Auto Scaling uses Application Auto Scaling, and requires permission to access Amazon CloudWatch alarms and AppStream 2.0 fleets. Users can manage fleet scaling using the AppStream 2.0 console or the AWS CLI. To use Fleet Auto Scaling, users must understand concepts such as minimum capacity, maximum capacity, desired capacity, scaling policy action, scaling policy condition, and scaling policy metric. To set a fleet scaling policy, users can edit existing policies or add new policies in the AppStream 2.0 console. The Fleet Usage tab can be used to monitor the effects of scaling policy changes.

This tutorial explains how to target applications in Amazon AppStream 2.0 to end users based on their Active Directory group membership. The tutorial assumes that the customer has an existing Microsoft Active Directory forest and an AppStream 2.0 Image Builder joined to the Microsoft Active Directory. The customer needs to have dynamic link libraries (DLLs) created before proceeding with the steps. The tutorial walks through the process of enabling the dynamic application provider on an AppStream 2.0 Image Builder, implementing a PowerShell script, creating a CSV file containing the required application information, and optionally configuring the solution to host the CSV file in Amazon S3 or use an Amazon DynamoDB table for storing application information. The solution uses the dynamic app provider in AppStream 2.0 and the PowerShell script to dynamically add applications to the AppStream 2.0 catalog based on the end user’s Active Directory group membership.
