Amazon S3 Large Object

Amazon Web Services (AWS) has recently increased the maximum size of an Amazon S3 object from 5Gb to 5Tb. This allows Amazon S3 users to store high resolution videos, disk drive images, computer backup files, and other large files as one S3 object.

To be able to upload objects larger than 5Gb, you will need to use the S3 Multipart Upload, which allows parallel uploads and streaming of large objects. If you use the Amazon S3 Management Console, you just have to enable large uploads. You can enable this in the Upload Files screen, which comes up after you click on the Upload button.

If you upload using an S3 client, make sure your client supports the S3 Multipart Upload API. Amazon recommends S3 users to use Multipart Upload for objects larger than 100 MB.

Amazon EC2 Basic Monitoring

Amazon has recently added basic monitoring to all Amazon EC2 instances. Before this change, you had to sign-up for Amazon CloudWatch to get any monitoring. Basic monitoring allows you to view and track metrics like CPU usage, disk IO and network traffic every five minutes. To get more information, you can sign-up for Amazon CloudWatch Detailed Monitoring. This gives you data every minute for $0.015 per instance-hour.

Another feature that was recently added to CloudWatch are alarms. Using the CloudWatch API, you can use these alarms to notify you of issues or trigger auto scaling of your EC2 instances. Visit the Amazon CloudWatch page for more information.
