Cloud Burst for Legacy Enterprise Applications

摘要

Cloud Burst is an automatically scalable application model in which applications run in a data center and use the public cloud to augment the capacity on demand. Critical legacy applications that have shown Data and User growth for many years may need extra capacity during spikes. The time when extra capacity is needed is always a crucial period from a business perspective. This makes it difficult for Enterprises to accept the risk of any capacity change in the critical application during the period even if technically feasible. Also, standard processes and models for suitability assessment and implementation are still not mature enough to harness the potential of cloud burst to full extent. The document gives an overview of strategy on how the potential of cloud burst model can be used for such applications while still mitigating the involved risk. The documents further discuss the alternate strategies in case cloud burst is not suitable for a given application landscape.
