What is Aurora Serverless?  Before we get into it, let us briefly define Aurora and serverless first. Aurora is a fully managed, closed source relational database that is compatible with MySQL and PostgreSQL. According to Amazon, it is five times faster than the standard MySQL and three times faster than PostgreSQL. It uses a distributed architecture that provides fault tolerance and high availability.  Serverless is a technique in the cloud that follows the ‘pay-per-use’ model. As opposed to its name, serverless does not mean not using ‘servers’. There is no magic in it. It still uses a physical server that [...]

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 [...]

Before jumping into the different AWS certification paths, it's good to first learn the benefits of being AWS certified through this short article. It is also important to note that AWS has scrapped the prerequisite for Professional-level exams. Previously, you could only take the Professional-level exams (Solutions Architect Professional and DevOps Engineer Professional) after passing their Associate-level counterparts. Now, you can take any AWS exam without the need to pass any prior AWS exam, which is ideal for those who already have extensive working experience in the industry.   In this short article, we'll learn more about the AWS Certification program [...]

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.  [...]
