Availability in the Cloud

Monday, July 28th, 2008 by

Today I came across a very interesting post, written by Mukul Kumar, which poses an intriguing topic of Cloud availability. Spawned most likely because of some “lack” of availability on Amazon’s S3 recently, Kumar discusses how companies might want to look towards creating redundancy across Cloud providers (such as GoGrid) in order to increase the availability of a company’s online presence.

All too frequently, companies look to a single solution for their hosting options, whether it be within the Cloud or using more traditional hosting methods. These single solutions can easily translate into single sources of failure, “don’t put your eggs in one basket” being the phrase the comes to mind.

Kumar illustrates some ways to make a company’s Cloud reliance a bit more redundant by using some traditional methods of choosing various providers.

Using a fairly straight-forward rsync (an open source utility that provides fast incremental file transfer) methodology, Kumar shows how servers can be configured as hot-standbys using different Cloud providers, allowing for redundancy to take place.
