Lifecycle Event Hooks in CodeDeploy

2023-06-02T02:57:06+00:00

Bookmarks Events Things To Consider In biology, life cycle refers to the series of stages or events that occur during an organism’s lifetime. Lifecycle also applies when automating software deployment on AWS CodeDeploy. Lifecycle event hooks refer to the series of events that describes how a deployment is accomplished. It allows you to control or perform actions on different stages of your deployment. In the traditional way, whenever you release a new feature for your application, you would have to manually disable the app and install the code. If the code resides in a repository [...]

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

Amazon Elastic Container Service (ECS) allows you to run Docker-based containers on the cloud. Amazon ECS has two launch types for operation: EC2 and Fargate. 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 [...]

Amazon S3 Access Points

2023-06-03T05:09:17+00:00

Managing access to your S3 buckets should be pretty easy using Amazon S3’s bucket policy. But as the number of your users and data grows, this easily becomes a complicated task. Provisioning access policies (who and where to access these objects) to these users could be a messy thing to do. AWS added this feature called Access Points on S3 to resolve this current problem. Access Points can simplify things in terms of provisioning access to different users. With this feature, each user can have a dedicated access point on a bucket and each of these access points has its [...]

Amazon S3 Event Notifications

2023-02-22T14:35:34+00:00

With Amazon S3 being virtually unlimited in size, it's quite a challenge to keep everything monitored, especially when you are dealing with a large number of objects that scales up from time to time. With Amazon S3 Event Notifications, you’ll be able to immediately know when an object in your bucket was created, removed, or restored. This feature lets you get notifications whenever an event happens on your S3 bucket. These notifications can then be forwarded to an Amazon Simple Notification Service (Amazon SNS) topic, Amazon Simple Queue Service (Amazon SQS) queue, and AWS Lambda function. The S3 Event Notification [...]

Configuring Notifications for Amazon EC2 Auto Scaling Lifecycle Hooks

2023-06-03T05:15:48+00:00

Auto Scaling Lifecycle Hooks In the previous post, we talked about Auto Scaling Lifecycle Hooks and how to configure it on your Auto Scaling group. You can view the article here. It’s better to read it first before proceeding with this section. In a nutshell, Auto Scaling Lifecycle Hooks allow you to put an instance in the “wait” state while the Auto Scaling group responds to a scale-out or scale-in event. While the instance is in the “wait” state, you perform actions such as installing the application before allowing traffic to the instance or sending out the application logs to [...]
