- Configure and manage users.- This service is an integral part of AWS.
Users are individual AWS accounts that can be granted access to your AWS resources. You can assign users specific permissions with policies or assign them to groups so they inherit the group's permissions. This means you can give different levels of access to certain services and control what types of actions each user is able to perform.
Groups are collections of users that share the same set of permissions. When you assign a policy to a group, all members of the group will receive those same permissions. AWS IAM groups provide a secure and consistent way for teams with varying needs and roles to access cloud resources without needing multiple administrative logins.
Policies define what actions a user or service may take on AWS resources. They are written using JSON and contain one or more statements that control who has access, what actions they may take, and which resources they can access. Policies are assigned to users or groups and govern how they interact with AWS resources, such as Amazon S3 buckets and EC2 instances.
{"Version": "2012-10-17","Statement": {"Effect": "Allow","Action": "s3:ListBucket","Resource": "arn:aws:s3:::example_bucket"}}
Roles are similar to groups. They also have associated policies, but roles are not tied to a particular user or group. They can be used to grant limited access to applications and users, allowing for greater security and control over resources. For example, an IAM Role can be assigned to an IAM user, and this role will determine what part of the AWS environment they have access to, such as EC2 instances or S3 buckets. Each IAM Role also includes a set of permissions rules which further limit what user activities can be performed within that role's scope.
A resource-based policy is a mechanism available on several types of AWS resources that allows granting access directly to the resource. In contrast to an IAM policy, which can only grant permissions to the principals managed in the account, a resource-based policy allows granting access to principals outside the account.
{"Sid": "AllowAccessToExternalAccount","Effect": "Allow","Principal": {"AWS": "arn:aws:iam::<ACCOUNT_ID>:root"},"Action": ["<service>:<PermissionName>"],"Resource": "<RESOURCE_ARN>"}
In this case, the “Principal” field is specified with a configuration that allows another account, via IAM policies, to grant access to the principals in it.

}- Login to your AWS account and open IAM service. Click Users under Access Management.- Click Add users button to set the user details and credential type as shown below.- Enter jmeter-s3-access in User name and check Access key - Programmatic access.- This user will have access to the AWS service programmatically, not from the user console. Click Next: Permissions.- In the Set permissions section, click Attach existing policies directly, and filter the policies of S3 by typing s3.- For the demonstration purpose, let us go with AmazonS3FullAccess. Check AmazonS3FullAccess and then click Next: Tags. But for the production server, follow the zero trust framework.- Adding tags is optional, but it is recommended to have relevant key-pair values.- Click Review and then click on Create user.- Copy the Access key ID and Secret access key to a secured location. Alternatively, you can download the .csv file.
Go to Services -> IAM -> Users -> Your-User-Name -> Security Credentials -> Create Access Key.
- Open the IAM console and click on Roles.- Click on Create Role.- Select Lambda from the use cases list and click next.- In attach permission policies, search for SNS.- Choose Read-Only Access from the list.- Finish the steps by given the role a descriptive name.

1. master must always be deployable.
2. all changes made through feature branches (pull-request + merge)
3. rebase to avoid/resolve conflicts; merge in to master
If you have participated in open source projects and contributed code, this is definitely not unfamiliar to you. Github has its own unique way, fork, pull request (PR for short), and issue tracking.
First, it will have a remote repository, and then each fork to its own repository. After the development is completed, PR will be sent to the remote repository. If you have any questions You can file an issue, and the person in charge will merge it into the master after approval.
Its core idea is PR and review. The review process is a natural code review process, which can help developers reduce bugs and make the code base more robust. If it is not for the cooperative development of multiple people in the company, I am more inclined to this.
Single version in production simple software
If your code is having only one version in production at all times (i.e. web sites, web services, etc) you may use github-flow. Main reason is that you don't need to complex things for the developer. Once developer finish a feature or finish a bugfix its immediately promoted to production version.
This is an algorithm that was created by Phil Zimmerman in 1991 using the RSA encryption algorithm. PGP encryption is different than other encryption algorithms because it doesn't require a server, certificates, or any other type of pre-shared secrets between senders and recipients to use encryption.
Someone with access to the public key can encrypt data without sharing secret keys with other users before sending them information. This makes it less secure but more flexible when compared to other encryption methods because anyone can send encrypted data without setting up complicated security options ahead of time.
