Architecting Hybrid Cloud Environments Publication Date: January, 2016 Authors: Victor Arzate, Shawn Gibbs; Michael Greene, Ian Lucas; Wagner Mota; Bala Natarajan; Uday Pandya Editor: Glenn Minch Summary: Hybrid cloud environments combine traditional on-premises IT with the consumption of cloud-based capacity (IaaS) and other cloud-based services. When carefully planned and executed, hybrid cloud models can deliver much of the best of both on-premises and cloud services. This paper focuses on understanding the different design approaches for architecting hybrid cloud environments, using technologies available from Microsoft, Microsoft Partner Solutions, and the Open Source community. Its objective is to enable IT architects to develop the right infrastructure strategies to deliver more of the potential promised by hybrid cloud-enabled scenarios. © 2015 Microsoft Corporation.

Enterprises are increasingly feeling pressured to leverage the cost economies and flexibility of cloud-based IT strategies. For most, the reality of current on-premises investments will dictate a gradual transformation from existing on-premises datacenters to cloud-based solutions. Even in the most aggressive pivot toward cloud-based IT, enterprises will continue to leverage their existing IT infrastructure, business applications, and IT processes. Hybrid cloud models, which combine traditional on-premises IT with the consumption of cloud-based capacity (IaaS) and other cloud-based services, play a critical role in bridging from traditional IT approaches to cloud-centric IT strategies. When carefully planned and executed, hybrid cloud models can deliver much of the best of both on-premises and cloud services. This paper focuses on understanding the different design approaches for architecting hybrid cloud environments, using technologies available from Microsoft and Microsoft Solution Partners. The Open Source community has contributed a number of useful tools that can help with management, automation, and testing in hybrid clouds. Our objective is to enable IT architects to develop the right infrastructure strategies to deliver more of the potential promised by hybrid cloud-enabled scenarios.
