What is Cloud Bursting?
When Cloud bursting is mentioned, we always speak of a hybrid cloud. An application runs locally in the private cloud, but it takes resources from the public cloud or is moved directly to the public cloud if the computing and storage capacities are exhausted in the local running environment.
Cloud Bursting targets
Cloud bursting's goal is to ensure the operation of the application even in the event of a sudden load increase, and in this case as cost-saving as possible. Long lead times are no longer needed, high investments are not necessary. Scale effects in the cloud are realized. At the same time, the user saves planning effort when he can scale resources without a long run. As a result, companies that rely on cloud bursting improve both their profitability and competitiveness.
Hybrid cloud constructs
Cloud bursting is always a component of a hybrid cloud construct. Cloud bursting finds its meaning when the public cloud share has already been prepared for the case of the need for cloudbursting and has been enabled to work at load points. Rules must be set when queries and traffic are routed to the public cloud. In addition to these guidelines, the necessary modifications to the DNS system must be prepared and so on.
Optimize cloud resources
Cloud bursting optimizes the use of cloud resources. Finally, however, the deployment must be planned precisely, in order not to provoke conflicts with data protection alone. As the Federal Office for Information Security (BSI) in its "Security Recommendations for Cloud Computing Provider" outlines, different security measures are necessary depending on the protection requirements of the data provided for the cloud. The security and confidentiality of personal data must, in principle, be respected, whether they are in the private cloud or in a public cloud. A German provider of public cloud computing naturally simplified cloud bursting.
