It’s been quite a long time now that the trend of Cloud computing is in emphasis, and I’m sure it will continue to be. There was a phase when no one had thought that the physical servers will be replaced by something called cloud computing. But when it did, people exaggerated it to be a saviour from their most troubled fear – Downtime!

To be precise, cloud computing is something wherein a pool of server hardware & software resources are formed within a highly reliable infrastructure and offered to operators to access different applications & programs from any device that contact the internet. It is usually believed that capitalizing on cloud computing ensures zero downtime & hikes scalability. This concept was followed by various players in market for a good period of time, but everything has its own limitations. The assumption that the cloud hosting services would be available 24 x 7 x 365 is proving out to be wrong gradually. Ofcourse someday it would be, it’s made up of machines after all. Techs around the world have different terminology of forming the cloud infrastructure and thus certain cloud services cannot be defined uninterrupted.

The outage of Amazon Cloud was a serious concern if the cloud technology is truly reliable and it would protect the major players from the downtime. It wasn’t the first time that people faced an interruption in their cloud server; many other cloud providers have also experienced this situation due to number of aspects. In actual scenario, an entire cloud never goes down; it’s just a part of it that gets affected. It can be because of the failures in hardware, power controllers, corrupt data in router tables or the base OS itself. Everything has its replacement however if the main replicating element itself goes down, nothing can help it to prevent from a downtime. Many natural disasters has also led to the downtime of the cloud infrastructures in the history and left the cloud sellers helpless.

These scenarios don’t appear consistently; hence the demand for cloud technology is still growing due to its advantages like scalability, performance & relative uptime. The hassle is not similar to what it was in late 2011 when cloud was predicted to replace the entire IT infrastructure, but it is not as bad as the graphs shows.
