Organizations are adopting cloud computing to accelerate service delivery. Some try to deliver
cloud economies of scale in their private data centers with the mantra “automate everything,”
a philosophy often simpler in theory than practice. Others have opted to leverage public cloud
resources for the added benefit of the pay-as-you-go model, but are finding it difficult to keep
costs in check. Regardless of approach, cloud technology poses the same challenge IT has faced
for decades: how to assure application performance while minimizing costs.
