Azure:Devops Stakeholder:Basic Access
https://stackoverflow.com/questions/48863308/in-vsts-how-to-move-access-level-from-stakeholder-to-basic-access
https://docs.microsoft.com/en-us/azure/devops/organizations/security/access-levels?view=azure-devops
Supported access levels
Assign users or groups of users to one of the following access levels:
- Stakeholder: Provides partial access, can be assigned to unlimited users for free. Assign to users with no license or subscriptions who need access to a limited set of features.
- Basic: Provides access to most features. Assign to users with a Visual Studio Professional subscription, an Azure DevOps Server CAL, and to users for whom you're paying for Basic access in an organization.
- Basic + Test Plans: Provides access to all features included in Basic, as well as Azure Test Plans. Assign to users with a Visual Studio Test Professional or MSDN Platforms subscription, and to users for whom you're paying for Basic + Test Plans access in an organization.
- Visual Studio subscription: Assign to users who already have a Visual Studio subscription. The system automatically recognizes the user's subscription—Visual Studio Enterprise, Visual Studio Professional, Visual Studio Test Professional, or MSDN Platform—and enables any other features that are included in their subscription level. If you assign Basic or Stakeholder, they also receive their Visual Studio subscription benefits upon sign-in.

All these defaults can be changed too
aws configure [Command to add Secret Key/Access Key using command Line itself]
role_arn and either a source_profile or a credential_source.
- Shared Credentials File
- AWS CLI Conflig File
They both contain Access_Key and Secret_Key
"CLI Config File" - access/Secret Keys are specific to that role
while
while
The shared credentials file has a default location of ~/.aws/credentials.
You can change the location of the shared credentials file by setting the AWS_SHARED_CREDENTIALS_FILE environment variable.
The AWS CLI config file, which defaults to ~/.aws/config has the following format:
[default]
aws_access_key_id=foo
aws_secret_access_key=bar
region=us-west-2
Profiles that aren't the default profile are specified by creating a section titled "profile profilename":
[profile testing]
aws_access_key_id=foo
aws_secret_access_key=bar
region=us-west-2
aws_access_key_id, aws_secret_access_key, aws_session_token. These are the only supported values in the shared credential file. Also note that the section names are different than the AWS CLI config file (~/.aws/config). In the AWS CLI config file, you create a new profile by creating a section of [profile profile-name], for example:
[profile development]
aws_access_key_id=foo
aws_secret_access_key=bar
In the shared credentials file, profiles are not prefixed with profile, for example:
[development]
aws_access_key_id=foo
aws_secret_access_key=bar
Credentials specified in the shared credentials file have precedence over credentials in the AWS CLI config file
Shared Credentials File > Config File
Precedence
The above configuration values have the following precedence:
- Command line options
- Environment variables
- Configuration file
Credentials can be specified in several ways:
- Environment variables
- The AWS Shared Credential File
- The AWS CLI config file

To view and copy the exact commands to mount your EFS file system using the mount target IP address
Open the Amazon Elastic File System console at https://console.aws.amazon.com/efs/.
In the Amazon EFS console, choose the file system that you want to mount to display its details page.
To display the mount commands to use for this file system, choose Attach in the upper right.
The Attach screen displays the exact commands to use for mounting the file system.

System status checks System reachability check passed
Instance status checks Instance reachability check failed
Note: A stop and start isn't equivalent to a reboot. A start is required to migrate the instance to healthy hardware.
The instance must be migrated to a new, healthy host by stopping and starting the instance. You can wait for Amazon EC2 to perform the stop and start of your instance. Or, you can manually stop and start the instance to migrate it to a new, healthy host.
When the instance is in the running state, choose Actions, Monitor and troubleshoot, Get system log.

By default EC2 instances are not redundant, Redundancy is achieved through using our other services such as Auto-scaling and Elastic lad balancing where you can mitigate around instance failure and make your application resilient of the components that it's running on.
You have to construct your server stack in a way that you don't care of the entire server goes away. In other words, keep your data in non-instance storage (EBS volumes, RDS, SimpleDB, S3). You have to have the mentality that your "instance" can go away at any time and it won't bother you, because you can click once and start up another one.
