10. Massive AWS, Microsoft Service Outages Raise Concerns About Public Clouds
A service outage that hit Amazon Web Services' S3 cloud storage systems on Feb. 28 wreaked havoc around the world, disrupting websites and Internet services for millions of users. A few days later Amazon apologized and blamed the outage on a botched effort by an employee to debug a billing system.
In March customers of Microsoft's cloud services were inconvenienced by several system outages, including storage availability issues with the company's Azure public cloud service in mid-March and a 17-hour Office 365 service outage on March 21 that kept users from accessing their OneDrive accounts.
With an increasing number of businesses dependent on cloud-based IT systems, the outages served as a wakeup call for solution providers and their customers of the potential pitfalls of putting all your IT resources in one public cloud basket. While public cloud systems offer cost advantages, the outages made clear the advantages of having a comprehensive cloud strategy incorporating both public and private cloud services with the requisite security and redundancy built in.
