I’m sorry, how does this answer any of the above questions? Please remove the marketing speak and address the questions asked.

Thanks in advance.

I found a bit more info and see that if Clustering is done the I/O can be improved, however Network latency/throughput (there are no guarantees on AWS) along with the troubleshooting errors/etc. still seem to persist, so I look forward to hearing a response.

Thanks

Hi folks, thanks for reading Barb’s piece and thanks for the feedback. Certainly, Red Hat Virtual Storage Appliance is not a one-size-fits all solution, however it will fit a great many. This solution has been deployed in production environments for approximately a year and customers are having success with it (see the CIC case study at http://www.redhat.com and more VSA case studies on the way). Barb’s included quote by Vanessa Alvarez is fair and accurate and each organization must make application choices that are best for their business. If they choose to move their apps to NAS in the AWS public cloud, then it is now a fully available and deployable solution. Tom Trainer, Red Hat Storage Marketing.

I can’t see how this would work with a ‘legacy’ application that was built with scale assumptions in the code. The hardest part about migrating legacy now days is pulling all the scale out of the code/application.

So how exactly can I/O be guaranteed (latency/throughput of Disk)? Image an app having entirely random I/O responses based on the AWS Infrastructure layer, I have a feeling quite a few legacy apps would not benefit from this. Let alone attempting to troubleshoot performance problems.
