Cloud services and cloud platforms are now an undeniable part of the IT landscape. Forrester research indicates the shift has begun from exploration of cloud as a potential option, to rationalization of cloud services within the overall IT portfolio.

Cloud platforms, most notably Amazon Web Services, were only collectively $4.7 billion last year but are maturing quickly thanks to stronger recent solutions from traditional IT partners IBM, HP and Microsoft. The growth in use, maturity, and financial viability of public cloud platforms are proving their longstanding value as legitimate deployment options for enterprise applications. While not a one-for-one replacement for on-premise, hosting, or colocation, cloud platforms fit well as ideal deployment options for elastic and transient workloads built in modern application architectures.

For applications and services built in an agile mode with modern architectures, discrete cloud services, such as database, storage, integration and other standalone cloud middleware components, will empower developers by freeing them from the management and maintenance of these components and reduce overall deployment footprint and cost. They are also managed and enhanced by vendors as often as daily delivering new capabilities that can help a company maintain pace with the changing desires of an empowered customer base

As the largest clouds continue to invest in efficiencies that can only be achieved at their massive scales, the gulf between the cost efficiencies that can be had from the cloud and what is possible on-premise or through other outsourcing and hosting options will widen dramatically.

How Forrester came to these conclusions.
