Hybrid Cloud Computing
Why is it becoming popular, Patterns, Trends, Impact
Dr. Marcel Schlatter, IBM Distinguished Engineer, Delivery Technology & Engineering, GTS 10 November 2010
Hybrid Cloud – Definition and Scope
Integration of traditional IT environments with one or more Clouds, on-premise and/or off- premise.
Composition of two or more Clouds that remain unique entities but are bound together by processes and technology to create a „System of Systems“.
Such „Systems of Systems“
– Can be composed of clouds from different vendors or service providers, e.g. IBM, Amazon, Rackspace, SalesForce, etc.
– Allow enterprises to keep core services and flexibly outsource other services to the cloud
– Seek to balance cost, speed, functionality and agility with the required manageability, security, privacy and confidentiality
Optimization Problem
Cloud is changing the way IT services are delivered, and consumed.
The initial transformation of traditional IT will be targeted at moving
workloads into a Mixture of Private and Public Cloud Environments

• Pay-as-you-go
• Outsource processing to the Public Cloud, while keeping business-critical data in private control
• Manual workload distribution
• Automatic, on demand workload distribution to absorb peak workloads
• Web hosting scenario with the web server in the Public Cloud (elastic scaling), and the database server in a Private Cloud, or in a traditionally managed on-premise IT environment.
• Support full application lifecycle, e.g.
development and unit test in the Public Cloud, and system test, performance test , and

The Multi-Site On-Premise Pattern applies to clients that have multiple data centers, each of them with a Cloud PoD (Point of Delivery), and with the need to have:
• an integrated view of resoures allocated and used across all their PoDs,
• the ability to dynamically move their workloads between their PoDs
• to use one PoD as a backup for another PoD, supporting manual or automatic failover scenarios.

in Private (on-premise) Clouds, and in off-premise Clouds in an IBM data center, or
in a data center of other service providers

Sourcing Vision
Separate out control functions of the computing services network, bundled in an on- premises system
In the longer term the operating environment will be largely or wholly automated and driven by policies that may include regulatory and compliance requirements, security, location, cost, and certain technical attributes.
Balance cost, speed, functionality and
agility with the required manageability, security, privacy, and
confidentiality Users will be able to request services with a set of policy attributes, and the management system will provide the requested services accordingly, combining and integrating on-premise and off-premise resources and information services from IBM and from other Cloud service providers
.
Optimization Problem
Allow Cloud-based service providers to advertise their services (which can be of
the SaaS or other nature). Interested consumers can find and consume them, with
the Cloud Service Broker in between, offering a spectrum of services, from
managing the service catalog to establishing a secure channel into the consuming
enterprise, to metering etc.
Enable two ore more enterprises to meet and collaborate in the middle,
on neutral, trusted ground

Community Cloud Pattern, enabling the members of the community share
access to data and applications in the cloud -- while making sure that each
member of the community can prevent their private data from leaking into
the community
„On-Premise“ Enterprise 1 „On-Premise“ Enterprise 2 Value Proposition
Community clouds have their infrastructure shared or distributed among enterprises with a common purpose.
A community cloud is controlled and used by a group of organizations that have shared interests, or a common mission (e.g. in the healthcare industry, or government agencies).
The members of the community share access to the data and applications in the cloud.
Example: A global cloud environment for clinical development that enables standardization both in-house and across the industry

In this context, a community is a group of organizations that have shared interests, or a common mission
Cloud is changing the way IT services are delivered, and consumed.
Hybrid Clouds, and Community Clouds enable global industry transformations.
Provider Chaining pattern, enabling Cloud services delivered by a
Federated Cloud Provider, i.e., a Broker that combines its own resources
with those of other providers.
The provider of the hybrid cloud, or the broker manage the cloud resources based on the cloud consumer’s terms.
The consumer of the hybrid cloud has no knowledge of what the hybrid cloud provider actually does.

Depending on their individual interests and concerns, stakeholders
typically see Hybrid Clouds from three different perspectives:
Sourcing Perspective
– Evolution of ecosystems will allow businesses to source, aggregate, and manage a wide range of services from many Cloud sources and vendors.
– Businesses will be able to create extended resource pools spanning multiple Clouds to allow different types of workloads to be provisioned by the most
effective Cloud or vendor from the perspective of cost, functionality, availability, performance, security, etc.
– Many of these Hybrid Cloud sourcing scenarios will require some form of Hybrid Cloud Integration in the sense of Cloud Brokering, i.e., business application and information integration, transformation, aggregation – and optimization.
