Most companies now use a range of cloud applications, and uptime performance for those applications is measured by Service Level Agreements (SLAs). These agreements acknowledge that glitches, system crashes and downtime have an enormous impact on business continuity and can adversely affect customer loyalty and churn. Gartner estimates downtime can cost major corporations as much as $100,000 per hour.
Unfortunately, not all SLAs are created equal, and worse, some SLAs are downright deceptive. IT leaders must evaluate SLAs to assure they cover minimum requirements for business continuity. The best SLAs have built-in strategies to increase uptime rather than clauses about reimbursements for downtime. When going through negotiations, watch out for these three lies:
1. SLAs with matching numbers of 9s are equal. If a vendor’s SLA guarantees a certain percentage of uptime during the month — such as 99.999%, or “five 9s” — that means the site won’t be down more than 1% of the time during the month, right?
Don't be so sure. First, get in writing that the definition of downtime includes not just "inaccessible," but also considerations for unreliable and unusable service caused by service performance degradation.
Another amazingly common practice is for vendors to exclude scheduled maintenance from their definitions of downtime. Don’t let them get away with it. Customers will be upset any time they cannot transact necessary business, whether one of your vendors foresaw the problem and “scheduled” the downtime or not. You don’t want customer turnover because your vendor allows timeouts that don’t count against their five 9s.
Look for vendors who have eliminated scheduled maintenance by using iterative maintenance strategies that avoid downtime. If your vendor doesn’t use this method, be sure to clarify the following areas:
- Performance indicators (What does “so slow as to be unusable” mean?)
- Problem management (What problem resolution responsibilities fall to the customer?)
- Terms and penalties (If terms aren’t satisfied, what exactly are the penalties and how are they enforced?)
2. “Satisfaction guaranteed or your money back” is a panacea. It turns out even the most generous fee refund or penalty for downtime doesn’t cover your losses. Here’s why:
Consider a cloud vendor’s self-described “industry-leading SLA” of 99.95% that credits your account 5% of the paid-in-advance monthly fee for each 30 minutes of downtime, up to 100% of your fee. Full refunds are only issued when downtime reaches 10 hours in a month! More importantly, a fee refund is trivial compared to the true potential cost of a 10-hour outage, which could include a loss in sales and customer confidence and result in customer churn.
