AWS EC2

AWS EC2 Image Builder
  • Allows you to create AWS EC2 images. These are virtual images and container images.
  • It’s really simple to use with a graphical interface.
  • We can use EC2 image builder to test and validate our images. We may need to test and validate the images for security, compliance and functionality, using AWS provided tests or your own custom tests.
  • EC to image builder automates the process of creating and maintaining your images.
    • When software updates are available, image builder can automatically create a new image, run validation tests on the new image, and make it available to the AWS regions of your choice.
    • Image builder allows you to share your AMI with other AWS accounts that you own.
  • Steps to create an image
    • Provide a base OS image. Example Amazon Linux 2 AMI.
    • Define software to install, example .Net, Node JS, python, latest security, updates, latest Kernel, security settings.
    • Run test on the new image for example, does it boot correctly etc.
    • Distribute the image to the regions of your choice. (By default, the region you are operating in).
  • EC2 image builder terminology
    • Image pipeline
      • Defines the configuration and end to end process of building images, including the image recipe, distribution and test settings.
    • Image recipe
      • Image builder creates a recipe for each image, which can be shared, version controlled, and re-used.
    • Source image 
      • Example Amazon Linux 2 AMI.
    • Build components
      • Example Apache tomcat.

Effect : Deny vs No Action

No action allows us to provide granular level control over resources operations. For example, if we use effect, deny For all actions in IAM An, then we use effect allow over some actions in IAM then deniable supersede allow. The way to overcome above issue is to use NoAction on all IAM operations And action on Allowed IAM operations. Example { "Version" : "2012-10-17" , "Statement" : [ { "Effect" : "Allow" , "NotAction" : [ "iam:*" , "organizations:*" , "account:*" ], "Resource" : "*" }, { "Effect" : "Allow" , "Action" : [ "iam:CreateServiceLinkedRole" , "iam:DeleteServiceLinkedRole" , "iam:ListRoles" , "organizations:DescribeOrganization" , "account:ListRegions" ,

RDS is not server-less. Aurora surverless is seven less which is an exception. Dynamo DB is server-less. There are two types of backups for RDS Automated backups Database snapshots Read replicas Can be multi availability zones. Use to increase performance Must have backups turned on. Can be in different regions. Can be MySQL,PostgreSQL,Maria DB, Oracle, Aurora, SQL Server is not supported. Can be promoted to master, this will break read replica. Multi availability zone Used for DRG only and not performance. You can force a fail over from one availability zone to another by re-booting the RDS instance.
