The term “Hybrid IT” is often used by analysts to describe the new function and operating model for IT in a cloud computing world. This definition is often restricted to simply combining cloud delivery with other types of delivery. The term Hybrid-IT should actually be used to describe an IT Operating Model whereby services are provided using the most appropriate delivery model such as cloud, but more importantly, Hybrid IT develops and manages a diverse and high performing IT supply chain in a truly multi-sourced and heterogeneous world.
The term “Hybrid IT” describes the next generation operating model for Enterprise IT in a multi-sourced, service integrated and cloud enabled world.
DefinitionIT A Hybrid IT organization is the trusted “broker of choice” for all IT services to the business, making it a differentiating business asset that enables Digital transformation.
At the heart of Hybrid is an agile and innovative service portfolio that delivers digital end to end business services, these services may be private or public, integrating services provided by both Enterprise IT and external managed service providers.
Best of breed service components will be selected based upon their utility, then integrated, customized, managed and governed in order to meet business and IT demands.
This style of service orientation will exploit both cloud delivery models and traditional styles of computing in order to deliver 2 speed IT
- Operational Speed is driven by a risk averse culture focused on efficiency, predictability adopting a stepwise approach that supports core business needs.
- Digital Speed focuses on being agile and flexible enough to support fast-paced, innovative initiatives that can deliver peaks of value that come together in a critical way to deliver digital business success.
A New Enterprise Blueprint for Hybrid-ITHybrid IT requires new Enterprise IT Operating Model and roles, where the infrastructure and Service Management organisation can take on or delegate management and delivery responsibility to external Managed Service Providers, Service Integration and Management (SIAM) and cloud services brokerages (CSBs) to deliver the needed IT services for the business.
The Hybrid IT function capabilities of Enterprise IT will become one of the most critical technology and organisational investments made by enterprises, and will influence how key decisions on all technologies and IT services used by the business are made and how they are delivered to end users.
Service Integration and Management is one of three layers in an enterprise model that describes a blueprint for Hybrid-IT.
Layer 1 is Retained or Enterprise IT which acts as the intelligent customer function that faces the business and acts as advocate for the business in delivering IT capabilities needed.
Layer 2 is the SIAM layer which orchestrates the integration and management of end to end services from best of breed components provided by the IT supply chain.
Layer 3 is the IT supply chain which is made up of internal and external managed services providers delivering best of breed service components using the most effective mechanisms.
Hybrid IT requires the working relationship between Enterprise IT and the business to evolve into one where Enterprise IT is the trusted broker for all IT services consumed by the business regardless of provider or style of service delivery. In a Hybrid IT model, Enterprise IT needs to be responsive to fast changing business needs and be able to quickly engineer end to end services across a diverse best of breed IT Supply Chain while continuing to take accountability for service delivery and service levels either directly or through its SIAM.
Example three layer in an enterprise model for Hybrid-IT
The Hybrid IT paradigm requires Enterprise IT to shift away from the classic monolithic outsource and vendor management model to a new operating model that equips Enterprise IT with the capabilities and roles needed to direct and govern the SIAM while behaving as the intelligent customer function to the business and custodian of the IT “Crown Jewels”.
