One of my customers is considering replacing all of their Flexpods with AWS Outposts. They see AWS Outposts as an extension of AWS where they are doing a lot of their development. Do we have any competitive information on AWS Outposts (software stack, application support, performance, data protection) of AWS Outposts compared to Flexpod?
I am not an expert on the two subjects to even suggest anything here but it's a very good question and I couldn't stop thinking about it. So I thought may be I could point to some Kbs here that I have seen on this subject.
There are a few limitations to point out wrt AWS outpost: • Only single node Cloud Volumes ONTAP systems are supported at this time. • The EC2 instances that you can use with Cloud Volumes ONTAP are limited to what’s available in your Outpost • Only General Purpose SSDs (gp2) are supported at this time.
AWS compute, storage, database, and other services run locally on Outposts. Outposts is available as a 42U rack that can scale from 1 rack to 96 racks to create pools of compute and storage capacity. Coming in 2021, Outposts will be available in two smaller form factors, 1U and 2U rack-mountable servers for locations with limited space or capacity requirements.
I guess, when it comes to Flexpod we are talking about compute/storage/network all stacked in a pod with pre-configured capability and so will the AWS outpost-racks will try to mimic. However, I think the key important differentiator could be that the 'flexpod' at your premise is still a on-premise well known ONTAP. However, in AWS it's all about the CVO (Single or HA Pair). I am guessing, more than the performance it may be down to the high availability of CVO (HA Pair) to ensure the uptime of mission-critical applications in the AWS outpost from "data serving function" perspective.
hmm...ok. Interesting to know that. Hoping to see more first hand feedback around CVOs performance running in Outpost. Apart from that I don't think there is any useful lab information around it or use cases.
