OpenSolaris supports EBS - provides capability to create ZFS

How to use EBS with OpenSolaris AMI  


Today Amazon Web Services announced  the availability of the most awaited feature of Persistent Storage (officially called as  Elastic Block Storage) on Amazon EC2 cloud. And, we are excited to announce that OpenSolaris does support creating ZFS file system on EBS. ZFS is the default file system in OpenSolaris and provides data integrity by 128-bit checksumming and has Rollback features to roll back any changes in the file system to a previous consistent state.

For detailed information on using EBS with the OpenSolaris AMI, please refer the document "Using EBS with OpenSolaris AMI"

 As an EC2 user, you probably know, running database servers on EC2 instances required you to put together mechanisms to backup the databases since the local storage wasn't persistent and would go away once the instances were shutdown or crashed. EBS solves this problem and provides local persistent storage which can be attached the running instances for database servers such as MySQL. Since MySQL is the most popular open source database server on EC2, it stands to benefit the most from EBS. Here's a link to Amazon Web services article on benefits of using EBS for MySQL. One of the benefits that I would like to highlight is:

Improved performance - Early reports from studies on EBS disk IO performance indicate that EBS IO rates can be multiple times faster than ephemeral storage and even local disk IO. This has obvious benefits for databases which are often IO bound.

Since, EBS provides capability to create file systems on the volumes, users can now take advantage of ZFS on EBS and you may get improved performance for certain workloads and database sizes. Here is an interesting article on MySQL and ZFS and performance comparison of ZFS Vs UFS file system (I think its OK to assume, ext3 will be comparable to UFS and hence these numbers may be a good comparison between Ext3 file system and ZFS

I am sure you'll find EBS feature useful and even better take advantages of ZFS on EBS. If you have any feedback or comments, as always, please send them to us via ec2-solaris-support [AT] SUN [DOT] COM.

Update: Capacity limit on OpenSolaris 2008.05 AMI

We are almost reaching the capacity limit on number of instances we have available on Amazon EC2 for running OpenSolaris 2008.05 AMI. As we continue to integrate and test OpenSolaris 2008.05 with EC2, we have limitation on the number of instances allocated currently. If you have been granted access to OpenSolaris 2008.05 AMI, please note that EC2_URL must be set to :

EC2_URL= Once Amazon team has completed testing, the URL will change and communicated.

Please note that the image re-bundling tools are being under development / testing at this time as well.

 Solaris Express.79 AMIs are available for deployment in full capacity. AMI / API tools have been completed ported and tested and are available for use.

 Thank you for your patience as Sun and Amazon continue to work together to make EC2 and OpenSolaris a platform to offer best development experience.

 If you have any suggestions or comments or would like to help out with OpenSolaris 2008.05 re-bundling efforts, please feel free to contact us at ec2-solaris [AT] SUN [dot] COM.

Launch of OpenSolaris on Amazon EC2

On may 5th, we announced the availability of OpenSolaris (2008.05) on Amazon EC2. Announcements were covered by GigaOm and Amazon's official announcement is here. We / MySQl also announced Amazon EC2 as one of the supported platforms, which meas if you already have purchased a support contract from MySQl, you can now deploy MySQl on EC2 and get same production level support from MySQL. These are two huge milestones which proves Sun's leadership in Cloud Computing space.



So, what did this collaboration between Amazon Web services and Sun do? It offers choice, choice to developers and startups in two ways-

1) OpenSolaris provides ZFS filesystem, first 128-bit filesystem which offer 64-bit checksum capability to maintain data integrity and Rollback functionality to be able to quickly rollback changes to the last known stable state in case of data corruption of instability in the fileysytsem. Secondly, OpenSolaris is the only OS which offers Dtrace - a observability and tracing tool which helps developers and administrators to debug and trace issues and bottlenecks right from the hardware level (OS level in case of EC2) to their application code and middleware in between. Most importantly, developers and EC2 users can now have choice of multiple OSes other than various variants of Linux.

2) Freedom to run MySQL on Cloud. MySQl is most critical component of any web applications and MySQL's commitment to support Cloud such as EC2 as supported platform, opens the doors for startups to leverage the cloud infrastructure to further reduce the cost and capex investment towards the infrastructure build-out at early stages of the company.

We are excited to be working with Amazon Web services and providing choice to developers, startups and students who wish to use EC2 cloud for their development and deployment use.

Welcome to OpenSolaris on Amazon EC2 Beta program!

Here you will find the latest information on the program and any late breaking information. OpenSolaris on EC2 team welcomes you and we look forward to providing you any technical assistance and information you need for a best possible OpenSolaris experience. Please feel free to leave comments here or contact us at ec2-solaris-support [AT] SUN [dot] COM.
