Cloud computing is a fad

Cloud computing continues to emerge as a disruptive technology, with high adoption rates and investment.

Cloud computing is not secure

security in the cloud has been good, but this is very cloud dependent and requires a solid design of security systems.

Cloud computing is not reliable

No system has 100% uptime all the time, and neither does the cloud. Given the scale, however, cloud services are typically designed to provide high redundancy and availability.

Cloud computing is not faster

There are different types of clouds and uses. In many instances, performance is higher in the cloud because there is more available capacity and scalability.

Cloud computing locks me to one provider

Clouds that implement standard technology stacks and are participating in cloud standardization efforts are your best bet to enable application mobility.

Summary: cloud computing is great, it's essentially a modern version of mainframe/thin client technology over the internet and it is a core driver of the exceptional value for money that we can get with online applications like facebook, amazon and even just standard website hosting.
