Amazon Web Services (AWS) Goes Hybrid

Amazon Web Services (AWS) Goes Hybrid

As the effective creator of the cloud Infrastructure as a Service (IaaS) market, Amazon Web Services (AWS) bore the onus of educating organizations on the value of the new model for delivering IT resources. In their role as unrelenting champions of the public cloud, AWS leaders publicly derided traditional infrastructure as archaic, and dismissed (at times aggressively) the efforts of traditional IT vendors to optimize private data centers with on-premises private clouds.

How times have changed. While AWS has built its strategy on the belief that hosted cloud will eventually replace most (if not all) private data center capacity—a position with which Stratecast cautiously agrees—the company has softened its antipathy toward the private data center. Today, AWS offers a number of services and reference architectures that support enterprise hybrid cloud configurations. The new approach acknowledges the continuing importance of the on-premises data center, especially to large enterprises and government organizations that have a lot invested in infrastructure and legacy software.

In this SPIE, we consider AWS’s definition of “hybrid cloud” compared to other industry definitions. We review AWS hybrid architectures and common use cases. Finally, we review several AWS software features that are available for use on-premises or on the Amazon Elastic Compute Cloud (EC2) service.
