Clouds Are No Substitute for Competence

More notes from Velocity.

Next session is Clouds Are No Substitute for Competence by Javier Soltero of Hyperic.


The promise of cloud computing:

Cloud computing is the next big thing:
Because it is green, easy, scalable, available and disposable.

Cloud computing adds complexity:

• clouds allow you to run your applications, but mask the performance of the infrastructure powering them. NYT is not going to stop their own infrastructure just because they had success with one project on EC2.
• when a problem happens, where is the source of the problem? cloud or your own app.
• cloud, by definition is always available and the status is always green.
• how quickly can I provision new servers?
• what is the throughput in the regions I use?
• what latency am I getting for my messages?
  

How do you answer?

• 'is it my application, or is it the cloud?"

Hyperic is introducing cloudstatus.com which shows performance, availability and health of Amazon's Web services. On CloudStatus.com, you can monitor EC2, S3, SQS, SDB and FPS (5 most popular and critical services of AWS). You can look at performance metrics such as deployment latency. They are firing Amazon instances and monitoring response times.
