I am only familiar with Rackspace of about 10 years ago. Beyond the marketing speak, what is their competitive advantage? Are they doing AWS prof serv?
You pay them so your ops team has someone to blame
They do AWS professional services since last year (I think) but we mainly use them for support as AWS doesn't cater for companies our size with their pricing.
Yeah, they acquired Onica which was/is a decently sized AWS prof services company. Not sure how much they were doing before then.
GCP, AWS and Azure now as well. They still have a bunch of on-metal, physical, and cloud customers as well.
