Amazon EBS Multi-Attach

2023-02-22T14:28:05+00:00

Amazon Elastic Block Store or EBS is a durable block-based storage device that can be attached to your EC2 instance. AWS released a feature called Multi-Attach, which allows EC2 instances to share a single EBS volume for up to 16 instances and provide higher availability of your applications for Linux workloads. Each instance to which the volume is attached has full read and write permissions to the volume. The following are several considerations and limitations in using the Multi-Attach feature: Multi-Attach enabled volumes do not support I/O fencing. I/O fencing protocols control write access in a shared storage environment to [...]

ECS Network Modes Comparison

2023-06-02T03:02:15+00:00

The EC2 launch type provides EC2 instances as hosts for your Docker containers. For the Fargate launch type, AWS manages the underlying hosts so you can focus on managing your containers instead. The details and configuration on how you want to run your containers are defined on the ECS Task Definition which includes options on networking mode.  In this post, we’ll talk about the different networking modes supported by Amazon ECS and determine which mode [...]

AWS CloudFormation Deletion Policy

2023-06-03T04:57:38+00:00

Deleting a stack on CloudFormation also removes all the provisioned resources in it. In some cases, you want some resources to be retained even after deleting its stack. The good thing is that you can do this by defining its DeletionPolicy.  This is pretty straightforward - you just need to define DeletionPolicy with Retain value and for the resources that support snapshot, (like RDS databases) you can set Snapshot as its value. With DeletionPolicy: Snapshot, a snapshot is created before a resource is deleted. This allows you to have a backup of the resource that's been deleted from the stack.  [...]

AWS CloudFormation StackSets and Nested Stacks

2023-06-03T04:59:37+00:00

AWS CloudFormation lets you model and provision resources for your environment using programming language, leveraging the concept of Infrastructure as Code (IaC). You don’t need to manually create all of your resources one by one, CloudFormation will do this for you. All resources are defined on the AWS CloudFormation template. This means that this AWS environment can be reliably and easily reproduced since everything is declared on a template. For example, creating a new Test environment similar to your current setup, or when creating a Disaster Recovery environment in another region.  With AWS CloudFormation, you can either upload your own [...]
