Programmed Responses in the Cloud

Proper automation lets IT workers create rules or specifications for cloud technology that drive how cloud solutions proliferate and situate themselves within the cloud and lets the tools generate the scripts or programs that do the actual work involved.

This covers scenarios that include fluctuations in demand, adding new or removing existing cloud services, components or applications, and responding to cyclical or seasonal market conditions. In a very real sense, this kind of automation makes cloud technology possible.

Another important area for automation falls under the heading of programmed responses to various triggers.

These include a broad range of events, such as the following, that might require millisecond-level reactions:
Changes in network link status
Users leaving or entering the cloud
Errors or failures in the network, servers, applications, or storage
Shift changes causing moves from call or data centers going offline to those coming online (following the sun around the globe is an easy way to understand this)

This kind of triggered automation also applies to the following types of events:
Detecting and dealing with security threats
Handling failover situations like those associated with business continuity and disaster recovery scenarios
Moving workloads from the private cloud to the public one, or vice-versa, for business or cost reasons

This is what keeps the cloud workable and cost effective over time – especially combinations of one or more private clouds, and one or more public clouds (called a hybrid multicloud).
