Disaster Recovery in The Cloud: AWS EBS Snapshot in a Single Click

cloud backupIn my journey through the cloud I often come across great new initiatives. The interesting fact is that although the cloud is a pure revolution terms such as SLA, TCO and ROI remain valid, new methodologies and techniques are presented to support them in the cloud.

How-to Estimate Your AWS EBS Volume’s Snapshot Costs - Part 2

EBS Snapshot costs feature imageIn part one I described the AWS EBS snapshot mechanism. In this part I will drill deeper on how to calculate the EBS snapshot cost. I ?will show how to be able to do a rough estimation or even to perform?an accurate cost analysis using monitoring tools.

Rough estimation

In order to estimate how large your EBS snapshots will be, you need to know how much your volumes are changing.?One way would be to guesstimate,we can use a simple thumb rule that is often used in- backup planning: A typical data volume of a production server changes about 3% a day. Let’s try and calculate the cost. Assuming a 1TB EBS volume, that is 70% full at first. We take snapshots and keep them for 30 days. So, the first full will be taking 700GB (70% of 1TB). For the incremental snapshots we can multiply 30 (days) by 30GB (3% of 1TB) and we reach 900GB. Add them together and we reach about 1.6TB of total snapshot storage. AWS compresses the snapshots when they are stored in S3.

How to Attach an EBS Volume with an AWS EC2 Windows Instance

The Amazon Elastic Block Store (Amazon EBS) offers persistent storage for the Amazon EC2 instances. Amazon EBS volumes provide a scalable storage service, which persists independently of the instance life. A user can attach an EBS volume to an EC2 instance. It is mandatory that both the volume as well as the instance be in the same availability zone. The user can assign a maximum of 16 EBS volumes to an instance. AWS allows the user to create the EBS volume.

The present guide demonstrates how attach an EBS volume to a Windows instance.

How to Format an AWS EBS Volume Attached to an EC2 Windows Instance

The Amazon Elastic Block Store (Amazon EBS) offers persistent storage for the Amazon EC2 instances. We saw that an EBS volume can be attached to AWS Windows instance for vertical scalability.

The present guide demonstrates how to format an EBS volume attached to a Windows instance.

How to Monitor the EBS Volume with Status Check and Enable Auto Enabled IO

AWS status checks help the user to identify problems that would stop the instance from running an application. The AWS EC2 status check allows the user to monitor the status of system reachability and instance status.?The EBS volumes are used for persistent data storage. It is always recommended to store the data to the EBS volume rather than having a transient storage for the persistent storage option. In the rarest of cases, there could be a probability that something could happen to the EBS volume, which could create inconsistency in the volume data. The AWS EBS volume status check helps to detect the impaired volumes. The impaired volume may not be available immediately.

The present guide demonstrates how to check the status of the EBS volume and enable auto enabled IO.

Estimating your Amazon EBS Snapshots Cost - Part 1: Block Level Incremental Snapshots

When using?Amazon?EBS snapshots for your?EC2?backup solution, you worry about stuff like automating EBS snapshots. To rely on EBS snapshots as a backup solution, however, you may want to be able to estimate the cost of storing the snapshots. Currently, the exact size of EBS snapshots is not available. In part 1 of this 2 part series, we will try to better understand how?EBS snapshots?work.

How to Attach an Amazon EBS Volume to a Linux Instance

The Amazon Elastic Block Store (Amazon EBS) offers disks storage for the Amazon EC2 instances. Amazon EBS volumes provide a scalable storage service, which persists independently of the instance life.

  • It is mandatory that both the volume as well as the instance be in the same availability zone.
  • The user can create a volume and assign a maximum of 16 EBS volumes to an instance.

RouteYou.com Deployment on AWS Cloud / by Accenture

The following presentation brought to you by an Accenture technology architecture consultant. The slides describes the deployment of routeyou.com, a high traffic site (avg 25K Visits per day). The presentation contains s short comparison between AWS cloud and Rackspace cloud with regards to storage and servers.

How to Migrate (Copy) an EC2 Instance Between Amazon AWS Regions

Move EC2 instance Between AWS Cloud RegionsAWS is ideally suited for making the user’s applications tolerant to disaster. One of the options for making the user’s application suitable to DR is to keep a backup of the data / application setup in multiple regions. If the first region is not reachable for some reason, the user can start the application from the other region.? In Dec, 2021 AWS introduced functionality to copy snapshots across regions.

Expert Guide: Amazon EBS Consistent Snapshoting

The following describes my personal case on how I maintained snapshots of my AWS EBS. The following requirements guided me with the scripts and tools I decided to use:

  1. Open source scripts and solutions within budget.
  2. Incremental snapshots maintain controlled and cost efficient growth
  3. Manage all volume’s snapshots for several AWS accounts from one central server.
  4. Advanced snapshot rotation mechanism and configuration options.
