Working With AWS CLI (AWS Command Line Interface)

2023-03-27T13:31:20+00:00

What is AWS CLI? AWS Command Line Interface (CLI) is a tool used to manage and interact with AWS Services using the command line.

Installed it on your local machine running on Linux, Windows, and macOS.   What is the Difference Between AWS CLI and AWS CloudShell? Likewise, AWS CloudShell is another tool you can use to manage AWS resources using the command line interface. But [...]

Event-driven Transfer on Storage Transfer Service for Google Cloud Storage

2023-03-27T13:33:33+00:00

Last January 7, 2023, Google Cloud announced a new capability for Storage Transfer Service (STS). Now, users can do an event-driven transfer quickly to a Cloud storage whenever there are changes to a source bucket. The event-driven transfer is an execution mode on Storage Transfer Service that allows transfer to a destination using the events from the source as triggers. Google Cloud claims that the transfer rate is near-real-time between the source and its destination. Here are some of the use cases of event-driven transfer: Event-driven Analytics Cloud Storage Replication/Data Aggregation Disaster Recovery/High Availability Cross-cloud Backup (AWS S3 backup to [...]

AWS CloudFormation Deletion Policy

2023-02-24T09:00:18+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

2023-02-24T09:03:14+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

2023-02-17T09:54:04+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 [...]
