Cloud Computing 366
Cloud computing is a service delivery model with great potential to offer numerous benefits. However, Cloud computing depends entirely on the availability of internet access for service delivery. While an Internet outage or problems with ISP are rare, you may not be able to access your cloud applications and do your work while access to net is limited. In addition, there may be certain problems with the service provider itself. For example
- In July 2008, Amazon’s S3 cloud storage service went down for the second time that year. A lot of applications were hosted by the company and all those services could not be accessed until technical teams could diagnose the problem and fix it. Some applications were down for as long as eight hours
- In 2009, the Gmail – the web based email service by Google was down for about 100 minutes.
Cloud applications store user data in data centers. These data centers may be located inside a country or outside. There are certain applications such as health that are legally bound store data on premise or inside a national territory.
