I have written a number of times about the advantages of cloud computing. However, not everything is perfect. For instance, Amazon had an outage on Thursday of part of its EC2 cloud computing service. It affected many web sites hosted by Amazon EC2 or Elastic Compute Cloud, including the FamilySearch forums.
Actually, Amazon has a number of different cloud-based services and only part of one service was affected. The Amazon EC2 outage was significant but the Amazon S3 and Amazon Cloud Drive services were unaffected.
