Business and IT leaders are understandably reluctant to retire considerable, legacy investment in technology, people, and processes due to security, risk, and regulatory compliance obligations. This creates a hybrid IT deployment model: an on-premise landscape of existing or legacy systems and off-premise cloud deployment of suitable IT capability. The ODCA believes that integration of cloud deployments with enterprise landscapes should consider people, process, technology, and operating models. Doing so encourages faster cloud adoption, leverages existing enterprise investments in IT landscape and helps govern safe cloud adoption through effective risk and compliance management.

1. HYBRID CLOUD & ENTERPRISE SYSTEMS
Achieving Successful Coexistence

2. INTRODUCTION
Context:
 Cloud Services are real, used today
 Internal IT has not gone away, and will probably stay on indefinitely to address:
• Processing of core workloads
• Centralise Orchestrations and process management
• Service Desk / Service Management
• Procurement
• Security, Audit & Compliance
 Both need to work co-operatively, and be governed “similarly, somehow”
Problem:
 What must one consider when planning how to manage and integrate the “Extended
Enterprise environment” at the people, process and technology layers?
Based on:
 ODCA members identified many challenges with making Hybrid IT really work
 “Cloud Co-Existence with Extant Enterprise Systems” paper lists many of their
learnings and recommendations

3. APPLICABILITY

Those who will find value in the Enterprise Integration Paper include:
Cloud subscriber – Use the list of layers to determine which areas should be considered when integrating
external services into the specific enterprise environment. The paper maps the important factors to be
considered on both the Transfer and Receive side of the interaction
Cloud Provider (internal IT organisation, or an external provider or other intermediary) – Create a set of
standard services and offering interfaces that meet the requirements for integrating with an enterprise
consumer and their governance environment, as a basis for interactions with potential customers / cloud
consumers, within a managed reference framework
Procurement – Important focus areas are identified to enable a standard approach to external integration of
cloud services and evaluation of a Cloud Provider’s offering in this aspect, at the enterprise integration level
Regulator – Determine list of minimum information required to enable acceptable governance and controls,
and require that this is demonstrated by both the provider and consumer at contractual and operational levels
Auditor – Evaluate the cloud contract for adherence to the recommended integration layers, and similarly for
the delivered services. Review solutions and services provided, by means of the list of interactions required
to enable governance in context of interface management and information transparency. This will enable
focus on key areas to support the operation and management of externally provided services within an
enterprises’ compliance profile

4. PROBLEM STATEMENT
4
Integration of cloud services into enterprise landscapes can be challenging
if not well thought through, and requires the following:
• Clear ongoing understanding at a governance level of the contracted cloud service
(from the cloud service provider) – what to consider?
• Identification of the specific applicable business use cases which determine what
external services are enabled and in turn the type of cloud solutions required, and
then in turn the integration points and applicable service level requirements. This will
determine the extent of integration.
• Determine if refinement is needed to extend an enterprise’s controls and
management processes to include cloud services – what to manage?
• Determine if Investment is needed in modernizing existing interfaces and
processes which comprise the current enterprise practices – what to update?

8. EXAMPLE: SERVICE DESK KNOWLEDGE MGMT
Enable enterprise to meet business service expectations, deliver interactive IT
support services anywhere, anytime.
To empower support teams with real-time collaboration and knowledge
management supporting cloud services:
 simplify complexities of Hybrid IT (Gartner Bi-Modal) by defining clear
documented services and functions/options (internal & externally aligned)
 extend Service Desks’ Knowledge DB to include suppliers, consumers, and third
party services
• covering common questions, answers, and incident- and problem-related information
pertaining to the cloud service
 use key ITIL service management processes across all parties (at defined levels)
for greater control and efficiency
 create comprehensive end-user self-service capabilities
 minimize number of problems and incidents overall e.g. pro-active gamification of
service desk on tips & tricks

9. CONCLUSION
1.Plan people, process and technology layers of integration as
you create your “extended enterprise”
2.Used a defined service integration framework between the
“extended enterprise” participants
3.Create well-defined integration points
4.Test against defined use cases
5.Train and Educate (consumer & provider)
