  3. 3. Everyone is talking about the cloud...
  4. 4. The significance of Cloud Computing <ul><ul><li>Cloud Computing changes IT services delivery in the same way that the ATM changed banking and the internet changed commerce </li></ul></ul>
  5. 5. Seismic Shifts: What the Industrial Revolution has to do with the Evolution of Modern IT Industrial Revolution – no single event , but an evolution of events and inventions over many decades Standardized processes in product manufacturing brought about significant changes in labour Cloud is the “Spinning Jenny” or “Watt’s Steam Engine” of its time: an essential part to the history of IT, but only a part of a much wider narrative How this narrative will play out over the next decade really is anyone’s guess There will be winners and losers In just the last decade, we’ve moved from static websites and slow internet modem dial-up to $$$Bn e-commerce, pervasive mobile and “tweeting” the world! In the next decade , we may have witnessed a dramatic transformation in the way IT is bought / consumed, to a highly flexible, pay-as-you-go, standardised model. All bets are off !
  6. 6. IT must address these Business Challenges Reducing risk Ensure the right levels of security and resiliency across all business data and processes Breakthrough agility Increase ability to quickly deliver new services to capitalize on opportunities while containing costs and managing risk Higher quality services Improve quality of services and deliver new services that help the business grow and reduce costs Doing more with less Reduce capital expenditures and operational expenses

  8. 8. A cloud computing primer – your 60 second guide Start Finish A new model of IT delivery and consumption… … inspired by internet services in the consumer space <ul><li>Key ingredients: </li></ul><ul><li>elasticity </li></ul><ul><li>PAYG </li></ul><ul><li>on-demand self-service </li></ul>Analogies - electricity generation and The Model-T Ford Evolutionary, not revolutionary – time sharing, hosting, ASP Variants – public, private, hybrid, community, G-cloud add to confusion Get to know the Cloud stack Near-term adoption overstated, long-term impact underestimated – all bets are off ! A “confluence of technologies” – virtualization, SOA, multi-tennancy ?
  9. 9. Cloud Computing Definition <ul><li>Cloud computing is a new consumption and delivery model inspired by consumer internet services and driven by client needs </li></ul><ul><li>Cloud computing has 5 key characteristics : </li></ul><ul><ul><li>“ Always on” network access </li></ul></ul><ul><ul><li>On-demand self-service </li></ul></ul><ul><ul><li>Location independent resource pooling </li></ul></ul><ul><ul><li>Rapid elasticity – grow & shrink easily </li></ul></ul><ul><ul><li>Flexible pricing models </li></ul></ul>… to free your budget for new investments and speed deployment of new capabilities.

  23. 23. An Infrastructure Strategy and Planning for Cloud Computing engagement can help answer the following client questions... <ul><li>Could we utilize cloud services, and why? </li></ul><ul><li>What types of services would be most appropriate? </li></ul><ul><li>How would they support our business and IT objectives? </li></ul><ul><li>Which cloud services would align best with our role as IT service providers? </li></ul><ul><li>What would be the likely benefits? </li></ul><ul><li>Would our current IT infrastructure support cloud service delivery (or not)? </li></ul><ul><li>What specific IT improvements would we need to make? </li></ul><ul><li>How can we develop a roadmap to achieve our cloud objectives? </li></ul><ul><li>Where do we start? </li></ul>
  24. 24. How we would develop a cloud computing strategy and plan 1 Pre-workshop call Client and IBM have a pre-workshop conference call to review engagement details and logistics and to begin the workshop scheduling process. IBM provides a pre-workshop data collection template. 1 – 2 weeks elapsed time 2 Data collection Client provides IBM with pre-workshop background material 3 Workshop preparation IBM prepares workshop materials based upon client-provided information. 1 week elapsed time 4 Client executive workshop IBM facilitators and client IT leadership members participate in a 2-day structured workshop. The 2-day client executive workshop is the key step within this strategy and planning engagement. 1 – 2 weeks elapsed time 5 Data analysis IBM conducts analysis of information gathered in the workshop and creates a final report presentation. 6 Client presentation IBM conducts analysis of information gathered in the workshop and creates a final report presentation. 7 Next steps
  25. 25. Next, we analyze the client’s workloads to determine the best starting point for your cloud journey.

  34. 34. Lessons Learned (1/5) <ul><li>Cloud computing doesn’t change everything (when implementing your private Cloud). </li></ul><ul><ul><li>Evolutionary in implementation, revolutionary in technology! </li></ul></ul><ul><ul><li>Normal IT project methodologies apply (mostly). </li></ul></ul><ul><ul><li>Leverage processes & skills you already have. </li></ul></ul><ul><ul><li>Cloud is not an excuse, for ignoring normal good business practice. </li></ul></ul><ul><ul><li>Ironically, everything that holds up “traditional” projects will hold up your first Cloud project. </li></ul></ul><ul><li>Some new aspects of Cloud do need to be carefully planned. </li></ul><ul><ul><li>(Cloud) Service definition, quality of service, evolution of the service, service catalog, and service life cycle need to be well defined and designed. </li></ul></ul><ul><ul><li>Clarity in use-cases, service catalog and non-functional requirements fundamental to success. </li></ul></ul><ul><li>Standardisation is key to achieving Cloud computing benefits. </li></ul><ul><ul><li>Cloud benefits will be maximised where few configurations (images) are used by many people, and minimised where many configurations are used by few people. </li></ul></ul><ul><ul><li>Only through standardisation can automation be cost-beneficial. </li></ul></ul><ul><ul><li>Each variable or choice point adds cost, and should be challenged. </li></ul></ul>
  35. 35. Lessons Learned (2/5) <ul><li>Start with a small, well-scoped project to show early success. </li></ul><ul><ul><li>Start small, grow fast. </li></ul></ul><ul><ul><li>Technology evolving quickly, and smaller agile projects can adopt in-flight changes. </li></ul></ul><ul><ul><li>Phased approach vital. </li></ul></ul><ul><li>Transparency of costs will drive change in consumption behaviour. </li></ul><ul><ul><li>Metering and charging of resource usage is vital to drive high utilisation. </li></ul></ul><ul><ul><li>If users are not encouraged to release resources, they will consume more than they need, and not release un-used resources back into the Cloud resource pool. </li></ul></ul><ul><li>Process optimisation is vital </li></ul><ul><ul><li>If current processes are fragmented, they should be optimised before moving to the Cloud. </li></ul></ul><ul><ul><li>Simplify where possible and minimise manual intervention / steps / approvals. </li></ul></ul><ul><ul><li>Automation and standardisation are king! </li></ul></ul>
  36. 36. Lessons Learned (3/5) <ul><li>A top-down approach (green field infrastructure) will achieve greater benefits </li></ul><ul><ul><li>Higher levels of service standardisation possible by designing from top-down. </li></ul></ul><ul><ul><li>Avoids “legacy” infrastructure & processes which may constrain the “purity” of Cloud services. </li></ul></ul><ul><li>Networks are the enabler as well as the inhibitor ! </li></ul><ul><ul><li>Access to the Cloud services requires secure front-end user access and back-end Cloud management for a viable Cloud solution. </li></ul></ul><ul><ul><li>Most enterprise networks are designed for separation & security, and actively prevent back-end access to network zones across business-units, countries and regions. </li></ul></ul><ul><ul><li>Early verification of network viability for Cloud services delivery is vital, especially when Cloud span beyond the data centre. </li></ul></ul><ul><li>Devil is in the detail </li></ul><ul><ul><li>Things appear very similar at a high level, but often very different at a detailed level. For instance, 20 Windows images maybe be 1 windows image with 20 instances, or genuinely 20 different reasons for why they are unique. </li></ul></ul><ul><ul><li>Greatest complexity in most Cloud solutions is network integration, and what network connections are required for each service and across services. </li></ul></ul>
  37. 37. Lessons Learned (4/5) <ul><li>Proof of concepts are powerful but also costly </li></ul><ul><ul><li>PoC’s for Cloud implementations are large & complex, often not much smaller than production implementations. Carefully consider if the onsite PoC is the right way to prove the concept. </li></ul></ul><ul><ul><li>Seeing is believing - There are many Cloud sceptics, but the power of seeing Cloud services being instantiated in minutes is extremely compelling. </li></ul></ul><ul><li>Cloud management solutions are complex </li></ul><ul><ul><li>Cloud computing abstracts the complexity of infrastructure into easy to consume services. The translation of complexity into simplicity is actually a difficult problem to solve. </li></ul></ul><ul><ul><li>Cloud solutions cut across many disciplines, and therefore require a multi-skilled team in hypervisor, image creation, networks, storage, server infrastructure and automation skills. </li></ul></ul><ul><ul><li>Do not assume these are easy to implement, unless using pre-packaged appliances (Cloudburst) </li></ul></ul><ul><li>Don’t forget the development and test environments for the CMP </li></ul><ul><ul><li>Just like most systems, the Cloud Management Platform should have comparable environments for testing fixes, applying patches, and developing new features before being deployed into the production CMP. </li></ul></ul>
  38. 38. Lessons Learned (5/5) <ul><li>Build to the lowest denominator </li></ul><ul><ul><li>Build the basics starting with IaaS capability and move up the stack to PaaS and SaaS offerings. </li></ul></ul><ul><ul><li>Low level changes can impact capabilities in higher service levels, so need to carefully plan where they are employed. Eg. Automatically applying a patch to an IaaS service could impact an application running upon it! </li></ul></ul><ul><li>Plan early on how to operate your Cloud </li></ul><ul><ul><li>Build a multi-discipline team embedded in a single group, to compliment the traditional delivery processes. </li></ul></ul><ul><ul><li>New Cloud processes will be required in addition to traditional service management processes. </li></ul></ul><ul><ul><li>These should focus upon the service life cycle from creation, instantiation, operation and termination. </li></ul></ul><ul><li>Be sure you’re implementing a Cloud ! </li></ul><ul><ul><li>Just calling something a Cloud, doesn’t make it a Cloud </li></ul></ul><ul><ul><li>It should be; </li></ul></ul><ul><ul><ul><li>Highly automated, ideally deploying services without any human intervention thru self-service </li></ul></ul></ul><ul><ul><ul><li>Based on virtualised resources for compute, network, storage </li></ul></ul></ul><ul><ul><ul><li>Highly standardised, offering few services with wide appeal. </li></ul></ul></ul>
