Creating an AMIs of the EC2 instance using AWS lambda and CloudWatch

In the era of Cloud and DevOps, maintaining multiple copies of your data will save you whenever there is something wrong with the server. A backup of your data is important, because you can restore your lost data using it. In AWS, you can take a backup of EBS. You can automate the backup of EBS using any custom script, which will use ec2 api and take a snapshot of the same. Earlier, we used to keep that script in any server and schedule it using cron; but now, we use lambda instead of server where we keep our script of taking a backup of EBS. Using lambda will remove the need of another server, which was needed to run the script on cron basis. Having EBS backup, means the snapshot is good, but if you have multiple EBS volumes attached to an instance, then it's recommended to take the AMI of the instance...
