Kristof Kloeckner, IBM CTO, Enterprise Initiatives and Vice President Cloud Computing Platforms on Cloud Computing and the Enterprise:
“This presentation will draw on IBM’s experience working with customers and operating 13 cloud centers world wide to review the conditions under which cloud computing can deliver its promise of flexibility and cost savings in the delivery of IT services to the enterprise.
Kristof Kloeckner will discuss the importance of dynamic infrastructures and service management for both public and private clouds, cloud service life cycles and integration between public clouds and enterprise services. He will also talk about standards required for interoperability between clouds and application scenarios that demonstrate the use of cloud computing in an enterprise context for a smarter planet.”
Cloud Computing Delivery Models: Public, Private and everything in between. I’ve reported on this slide previously:
“From consumer perspective, Public clouds offer standardization, capital preservation, flexibility and time to deploy. Private clouds offer customization, efficiency, availability, resiliency, security and privacy. Choice will depend on organization, culture, and governance.”
Cloud-o-nomics:
(1) virtualization + energy efficiency + standardization + automation (service management) = reduced cost
(2) agility + business & IT alignment + service flexibility + industry standards = optimized business
- allows you to optimize new investments for direct business benefits.
Kristof agrees with “some analysts” that cloud computing is related to, and benefits from, SOA.
5 Step Plan – IT Transformation Roadmap --- not a “rapture into the clouds for IT geeks”
1. Simplified | Consolidate – reduce infrastructure complexity, freeing up resources, improve business resilience, reduce TCO
2. Shared | Virtualize – remove physical boundaries between resources, increase hardware utilizations, simplify deployments,
3. Dynamic | Automate - introduce standardize services, service management, metering & measurement, granular services
Three roles in respect to cloud computing: end-users & operators (service catalog, operational console), service provider (cloud services & cloud management platform) & service creation and deployment (service definition, publishing, fulfillment & configuration, reporting & analysis). Items in ( ) are primary concerns and tools for that role. (Yes, I imagine you can map this to ITSM and the Tivoli and WebSphere product lines. Oh, and Rational, Kristof just mentioned that for modeling a service deployment topology. (Krutchen 4+1 Architecture and all))
Customer discussions often start with “help me virtualize my workloads”. Next, “can we move this into a shared, trusted, private cloud”. Finally, “what is possible to be deployed into public cloud”.
Given multi-cloud environment, need to ask about how services and data flow across clouds. Need to understand security – identity & trust. Also, connectivity or a (wait for it) “cloud broker”.
Ideally, information and services will flow freely across clouds, in secure and standardized manner. This leads Kristof to the Open Cloud Manifesto. He has the principles listed. IBM is supporter, describes it as a first pass. As you may have read, not everyone supports the Cloud Manifesto.
In analyzing workloads for cloud or not, need to:
- examine for risk: database, transaction processing, ERP
- test for standardization: web infrastructure, collaborative infrastructure, development & test, high performance computing
- explore new workloads: high volume, low cost analytics, collaborative business networks, industry scale “smart” applications
4. Pick cloud model – private, public, or hybrid
5. Implementation
Ugh! Missed a good metric. Kristof spoke of setting your cost savings metric and then measuring your cloud projects against it. If project doesn’t meet metric, move along. But, I missed the #.
Now, IBM Cloud Computing Services Offerings… Seems like “bursty workloads” are a target.
Next, the obligatory global map showing cloud computing center locations. Everyone had one yesterday as well.
“start now with virtualization”
“modularity and standards are key”
