Gartner analyst: HP SLA slightly better than AWS SLA

Tools

In Monday's newsletter, we ran an item that cited Gartner analyst Lydia Leong's recent posting on cloud provider service level agreements. Leong had lambasted Hewlett-Packard (NYSE: HPQ) and Amazon (NASDAQ: AMZN) Web Services for insisting on architecture service requirements that essentially render the agreements useless. Leong later updated her post after speaking with HP. In the update, she emphasized that her fundamental opinion in the earlier post hadn't changed but "the nuances make the HP SLA slightly better than the AWS SLA."

"The most significant difference between the SLAs is that the HP's SLA is intended to cover a single-instance failure, where you can't replace that single instance; AWS requires that all of your instances in at least two AZs be unavailable," Leong wrote.

Under the HP SLA, you have to try to re-launch in a different AZ if there's a failure, but if it doesn't work, you're covered under the agreement, she said. 

The best SLAs are "plain-language comprehensible," Leong wrote. "Both HP and AWS sin in this regard, and frankly, many providers who have good SLAs still force you through a tangle of verbiage to figure out what they intend."
