AWS CLI

AWS CLI is a command line interface (CLI) that allows users to perform operations on Amazon's AWS (Amazon Web Services) cloud service using commands. It allows operations related to resource management of cloud services, which are usually performed using a console on a web browser, to be executed as Linux commands. Therefore, it can be used to connect Genkai to cloud services, for example, by automatically performing a series of investigations using shell scripts.

AWS ParallelCluster is a tool for managing clusters on AWS. It allows you to create clusters on demand with the configuration you need, and remove them when they are no longer needed.

Please note that the Genkai account contract does not include cloud service resources. the center does not accept requests for contracting cloud services on behalf of or using cloud services. ct the following for information on using AWS.

Preparation

AWS account creation and acquisition of access key and secret key

To use the AWS CLI or AWS ParallelCluster, you must first create an AWS account and its root user access key and secret key. Please refer to the procedures below. For more secure usage, it is recommended to use AWS as a user other than the root user. In this case, create a separate IAM user and obtain its access key and secret key.

• Create an AWS account
• Create access keys for the root user
• Create an IAM user in your AWS account
• How an IAM administrator can manage IAM user access keys

AWS settings
