Not ideal, but works on a certain level. Latency is the most important for companies that run real-time applications such as video conferencing, surveillance systems or VoIP. Disposable latency of 100 ms or less is well suited to these applications. But if you are a player, with quick reflexes, then 50 ms or less is ideal. Studies show that even the most attentive eyes cannot perceive latency below 20 ms. Small differences in latency, less than 20 ms, therefore do not distinguish significantly the services. Commercial services generally guarantee unilateral latency of 25 ms or less, suitable for almost all cloud applications. Service credits are the typical compensation for missed ALS metrics.
Service credits can be complicated to compare. The promise of 100% operating time is an example. We all know that every service and every product has downtime. Nothing is 100%. Nevertheless, some ALS all 100% uptime. But if you read the fine print, corrective action will only apply when the service has fallen to 99.95%, which may be the same level as the 99.99% time guarantees to remedy it. In case of chronic problems, contracts can usually be terminated without penalty. The savvy buyer will also dig into service credits to fully assess the expected level of performance for his business. 4.5.1.
