Amazon EC2 and S3 are the most widely used services in Amazon. EC2 being instance based compute service and S3 being a lightweight storage service. It is always a good practice to create a backup for your EC2 instances so that if your instance is deleted or stops working you can restore EC2 from snapshot created. Find out more about the “Amazon Web Services Architect Courses“.
Creating backups and recovery modules are one of the best methods for disaster management. In the case of data loss, you can always use the backups so that your work, business is not affected. Now that you know why backups and recovery modules are necessary, let me guide you through the topics that I will be discussing in this article about “How To Restore EC2 From Snapshot“.
Amazon Web Services commonly known as AWS is a subsidiary of Amazon that provides on-demand cloud computing platform. AWS provides many services out of which EC2 and S3 are the ones which are commonly used.
Amazon EC2 forms the central part of Amazon’s cloud computing platform. Amazon allows individuals to rent virtual computers to run their own application. These virtual computers are known as an EC2 instance. EC2 instance in AWS are pre-defined with most commonly used Operating systems, you can create an operating system as per your requirement also.
Amazon S3 is a “simple storage service” provided by Amazon that provides object storage in the web interface. S3 uses the scalable storage infrastructure to provide storage to its customers in the global e-commerce network.
In this article, we will be focusing mostly on EC2 and S3. Now that you know what is Amazon EC2 and Amazon S3, let’s find out how are we going to use it in the process to restore EC2 instance using snapshot.
Amazon EBS (Elastic Block Storage) provides raw block-level storage that can be attached to Amazon EC2 and also used in Amazon RDS. Amazon EBS was launched in August 2008. EBS is used at places where there is:
EBS Snapshot is used to backup data from EBS Volume to S3 by taking an in-time snapshot. Snapshot is nothing but an incremental backups. The nature of EBS Snapshot is same as that of the original volume (encrypted or not) and the nature of volumes created by EBS Snapshot remains same as that of the Snapshot (encrypted or not).
You can backup your data present in EBS Volume to Amazon S3 by taking point-in-time snapshot. Snapshots are incremental backups. Incremental backup means a copy containing only the files which are updated. This helps in minimizing the time required to create the backup.
Now that you know all about the things related to the storage services provided by Amazon, let’s learn how you can implement the above-given information practically.
In the article about how to restore EC2 from Snapshot, I will be working on the following things:-
Let’s take a closer look at each of the steps.
This was the process to restore EC2 Instance using Snapshot is successful. I hope you understood the demo. The best way to learn is by implementing it. Go ahead and implement it.
