Even superhuman operations people can’t be alerted and take action in under 5 minutes. One outage per year could drop service level to three nines or worse.

Notas del editor
- How many users are using
- IN the late 1800s English economist William Stanley Jevons noticed that despite huge increases in the efficiency of coal burning, demand actually increased rather than decreased. In cloud computing despite huge cost savings the consumption of cloud computing is and will continue to grow as demand increases. The downside is that this increased consumption has the ability to increase management burden if users don’t adopt leveraged methods for managing cloud computing.
- With a credit card and a single administrator can spin up 100s of servers in minutes.
- How does the management personnel for the cloud scale? …Automation.
- DevOps is a popular movement among cloud operations professionals who are advocating many of the same methodologes used in Agile software development.
- Ideally for the cloud you create management toolchains that automate the management of your cloud.
- Cloud computing promises highly available systems, but if you have a reactive approach you won’t achieve that goal. Build redundant, highly automated systems that can self-heal.
- Other disciplines like back-up, log management, performance and security (virus,intrusion detection) are important but not core to the delivery of cloud computing systems
- Tools that can automatically build your systems/install systems
- Configuration management tools abstract infrastructure into variables that are implemented via “recipes”Interesting new development is the PXE boot Crowbar extension for Chef Server used to provision virtual machines in OpenStack.
- API lets you develop to one API and move between cloudseasilyTypesof Tasks Accomplished by an APIProvisioning (creating, re-creating, moving, or deleting components e.g. virtual machines, vlans)Configuration (assigning or changing attributes of the architecture such as security and network settings)Cloud ProvidersJclouds – java API Abstraction Libcloud – started by CloudKick (now Rackspace) to abstract clouds, Apache incubator projectDeltacloud – started by Red Hat to abstract clouds, Apache incubator projectFog – started by EngineYard is a ruby gem that allows you to interact with number of cloud API.
