SOA and Cloud Computing
               • One can consider cloud
                 computing the extension of
                 SOA out to cloud-delivered
                 resources, such as storage-
                 as-a-service, data-as-a-
                 service, platform-as-a-service
                 -- you get the idea.
               • The trick is to determine which
                 services, information, and
                 processes are good
                 candidates to reside in the
                 clouds, as well as which cloud
                 services should be abstracted
                 within the existing or emerging
                 SOA.
                                                                              4

When Cloud Computing may be a Fit

               • When the processes, applications, and data are
                 largely independent.
               • When the points of integration are well defined.
               • When a lower level of security will work just fine.
               • When the core internal enterprise architecture is
                 healthy.
               • When the Web is the desired platform.
               • When cost is an issue.
               • When the applications are new.

Getting Ready
               • So, how do you prepare yourself? I have a few
                 suggestions:
                               – First, accept the notion that it's okay to leverage services
                                 that are hosted on the Internet as part of your SOA. Normal
                                 security management needs to apply, of course.
                               – Second, create a strategy for the consumption and
                                 management of cloud services, including how you'll deal with
                                 semantic management, security, transactions, etc.
                               – Finally, create a proof of concept now. This does a few things
                                 including getting you through the initial learning process and
                                 providing proof points as to the feasibility of leveraging cloud
                                 computing resources.

Stepping to the Clouds
               1. Access the business.                                         10. Identify candidate processes.
               2. Access the culture.                                          11. Create a governance strategy.
                                                                               12. Create a security strategy.
               3. Access the value.

Other Thoughts
               • External cloud services should
                 function like any other
                 enterprise application or
                 infrastructure resource.
               • You should evaluate cloud
                 providers using similar
                 validation patterns as you do
                 with new and existing data
                 center resources.
               • Cloud resources should appear
                 native.
               • Consider Private Clouds.
               • Watch the hype, the resources
                 are new, but the patterns of
                 architecture are familiar.

SOA and Cloud Computing • One can consider cloud computing the extension of SOA out to cloud-delivered resources, such as storage- as-a-service, data-as-a- service, platform-as-a-service -- you get the idea. • The trick is to determine which services, information, and processes are good candidates to reside in the clouds, as well as which cloud services should be abstracted within the existing or emerging SOA. 4 © 2006 The Linthicum.

  • 14. Getting Ready • So, how do you prepare yourself? I have a few suggestions: – First, accept the notion that it's okay to leverage services that are hosted on the Internet as part of your SOA. Normal security management needs to apply, of course. – Second, create a strategy for the consumption and management of cloud services, including how you'll deal with semantic management, security, transactions, etc. – Finally, create a proof of concept now. This does a few things including getting you through the initial learning process and providing proof points as to the feasibility of leveraging cloud computing resources. 14 © 2006 The Linthicum.
