Even outages as brief as 10 minutes can have serious ramifications for users who are trying to access time-sensitive content, so organizations that rely on cloud-based services for things like storage, email and collaboration applications need to carefully vet providers, said industry analyst Michael Osterman from Osterman Research.
CIOs and IT managers need to evaluate providers' level of redundancy, service level guarantees and security safeguards, for example, to make sure they match the requirements of their organization.
However, he cautioned against assuming that cloud-based services are more prone to outages than systems housed inside companies and managed by their IT department.
"It is important to note that on-premise, internally managed systems can be subject to the same types of problems and the same impacts on downtime. These kinds of internal outages are rarely reported outside the company, and so it can appear that cloud-based services are less reliable than internal systems and that is normally not the case," he said via email.
