Elastic Compute Cloud (EC2) instances and Simple Storage Service (S3) are two of the most widely used AWS services. When transferring data between these services, one should consider the costs involved (both upfront and hidden). Generally, the EC2 to S3 data transfer cost is virtually zero if they are in the same region. However, transferring…

EC2 Auto Scaling is a fully managed service that helps your application get the required number of instances by automatically launching or terminating EC2 instances. We generally create collections of EC2 instances known as Auto Scaling Groups, each having a specified number of instances. Auto-scaling ensures that size gets maintained, not letting the group go…

Stopped EC2 instances do not cost money. However, sometimes, a stopped EC2 instance may still have some Elastic IP addresses, EBS volumes, or other resources attached to it. In that case, you might get charged despite stopping your EC2 instance. But the cost should be a fraction of the running cost of the instance. Or…
You can add an IAM role to an EC2 instance through the EC2 console, AWS CLI, or other options like Terraform and Amazon CloudFormation. Whether you like working with an easy GUI or prefer streamlined command lines, these approaches should work fine. Let’s have a closer look at how to add an IAM role to…
AWS does not provide a direct option to move an existing instance to a new Availability Zone. However, there’s a workaround if you want to change the Availability Zone of an EC2 instance. The process includes creating a new AMI from your EC2 instance and manually migrating it. After that, you need to launch a…
Installing MongoDB on the Ubuntu EC2 instance in AWS is an excellent option if you plan on shifting to a NoSQL database. On top of the AWS benefits, you can expect efficient data management, on-demand scaling, and better security. Let’s see how the installation process works with a step-by-step approach. How to Install MongoDB on…
Deleting an EC2 instance is pretty easy, whether through AWS Management Console or the Command Line Interface. But once you terminate an EC2 instance, you cannot undo it. So, you may want to stop or hibernate as an alternative to deleting. That said, you can always launch more instances with the same AMI. Can You…
Data migration is the process of selecting, planning, extracting, and changing information and permanently exchanging it from one computer capacity system to another. Data transfer between frameworks is becoming increasingly essential as businesses create and receive new innovations. Data migration guarantees a consistent data stream amid upgrades, information consolidation, or stage moves. Whereas vital, it requires careful…
Amazon EBS Multi-Attach allows EBS volumes to be attached to multiple EC2 instances within the same Availability Zone (AZ). You can connect several Multi-Attach enabled EBS volumes to a single EC2 instance or a group. However, you should be aware of certain limitations associated with using Multi-Attach. These include potential compromises in performance and security,…
There are two ways to migrate an EC2 instance: 1. Using the AWS Systems Manager automation document and 2. Manually copy the EC2 instance and launch a new one. However, we recommend the second option if you want to move your EC2 instance to another VPC (Virtual Private Cloud). Can You Move an EC2 Instance…
