A stack is a collection of AWS resources that you can manage as a single unit. In other words, you can create, update, or delete a collection of resources by creating, updating, or deleting stacks. All the resources in a stack are defined by the stack's AWS CloudFormation template.

 

Root access should not be used and should have MFA enabled

 

Amazon Simple Queue Service (Amazon SQS) offers a reliable, highly-scalable hosted queue for storing messages as they travel between applications or microservices. It moves data between distributed application components and helps you decouple these components.

 

SNS can send push notifications See: https://docs.aws.amazon.com/sns/latest/dg/SNSMobilePush.html

If you want the URL for your sign-in page to contain your company name (or other friendly identifier) instead of your AWS account ID, you can create an alias for your AWS account ID. See: https://docs.aws.amazon.com/IAM/latest/UserGuide/console_account-alias.html

https://docs.aws.amazon.com/IAM/latest/UserGuide/console_account-alias.html

When you create IAM policies, follow the standard security advice of granting least privilege—that is, granting only the permissions required to perform a task. See: https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege

https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege

A scaling plan tells Auto Scaling when and how to scale. For example, you can base a scaling plan on the occurrence of specified conditions (dynamic scaling) or on a schedule. An autoscaling policy defines how to scale and how much scaling to be applied. A scaling plan will reference a scaling policy.

 

By default, the “automatic rollback on error” feature is enabled. This will cause all AWS resources that AWS CloudFormation created successfully for a stack up to the point where an error occurred to be deleted. This is useful when, for example, you accidentally exceed your default limit of Elastic IP addresses, or you don’t have access to an EC2 AMI you’re trying to run. This feature enables you to rely on the fact that stacks are either fully created, or not at all, which simplifies system administration and layered solutions built on top of AWS CloudFormation.

An instance store provides temporary block-level storage for your instance. This storage is located on disks that are physically attached to the host computer. Instance store is ideal for temporary storage of information that changes frequently, such as buffers, caches, scratch data, and other temporary content, or for data that is replicated across a fleet of instances, such as a load-balanced pool of web servers.

You can and should use an IAM role to manage temporary credentials for applications that run on an EC2 instance. When you use a role, you don't have to distribute long-term credentials (such as a user name and password or access keys) to an EC2 instance. See: https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2.html

Long polling helps reduce your cost of using Amazon SQS by reducing the number of empty responses. You can enable long polling using the AWS Management Console by setting a Receive Message Wait Time to a value greater than 0. See: https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-long-polling.html

https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-short-and-long-polling.html#sqs-long-polling

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Stop_Start.html
