Gartner: Amazon, HP cloud SLAs are "practically useless"

By Brandon Butler, Network World |  Cloud Computing, Amazon Web Services, Gartner

Amazon Web Services, which Gartner recently named a market-leader in infrastructure as a service cloud computing, has the "dubious status of 'worst SLA (service level agreement) of any major cloud provider'" analyst Lydia Leong blogged today, but HP's newly available public cloud service could be even worse..

HP launched the general availability of its HP Compute Cloud on Wednesday along with an SLA. Both AWS and HP impose strict guidelines in how users must architect their cloud systems for the SLAs to apply in the case of service disruptions, leading to increased costs for users.

AWS's, for example, requires customers to have their applications run across at least two availability zones (AZ), which are physically separate data centers that host the company's cloud services. Both AZs must be unavailable for the SLA to kick in. HP's SLA, Leong reports, only applies if customers cannot access any AZs. That means customers have to potentially architect their applications to span three or more AZs, each one imposing additional costs on the business. "Amazon's SLA gives enterprises heartburn. HP had the opportunity to do significantly better here, and hasn't. To me, it's a toss-up which SLA is worse," Leong writes.

Cloud SLAs are an important topic, as recent outages from providers like AWS have shown. AWS has experienced three major outages in the past two years, including a recent one that took down sites such as Reddit, Imgur and AirBNB. Each of AWS's outages have been limited in scope, however, and have mostly centered around the company's Northern Virginia US-East region.
