Cloud Services helping in cloud service to be fully knowledgably .pptx
- 2. Cloud Computing Is it right for you? John Craddock [email protected]
- 3. What is Cloud Computing?
- 4. A Simple Definition Making computing resources available as a utility service Just like the National Electricity Grid Electricity: No need to know about how or where it’s generated Available through a well defined interface Available everywhere and for many devices Power output, scales on demand Low capital expenditure for consumers Pay for what you use Reliable
- 5. Not All Clouds Are Right for You
- 6. So What’s Changed? Time…. Bureau service The future Main frame The 60s Well defined interface? Compute on demand Pay as you go + Available everywhere + Available to many devices + Agility Low capital expenditure for consumers I don’t know how it works, I just get the answers I need
- 7. On-Premise Computing • Requires hardware, space, electricity, cooling • Requires managing OS, applications and updates • Software Licensing • Difficult to scale – Too much or too little capacity • High upfront capital costs • You have complete controland responsibility
- 8. Managing Demand Time IT Capacity Entry barrier Under capacity Over capacity Forecast demand Potential business loss Wasted capacity Compute capacity
- 9. Demand Burst Time IT Demand Concert ticket web site Ticket sales open Ticket sales open Ouch! How do we deal with this?
- 10. IT Agility • How quickly can you – Scale up the infrastructure and applications? – Upgrade to the latest OS? – Respond to a company merger with new requirements for business process and IT capacity? – Respond to a divestiture
- 11. Cloud Computing • Shared, multi-tenant environment • Pools of computing resources • Resources can be requested as required • Available via the Internet – Private clouds can be available via private WAN • Pay as you go
- 12. Cloud Services Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS)
- 13. The Stack Operating System Frameworks Application OS Services Virtualized Instance Hardware High-speed network
- 14. Software as a Service (SaaS) Operating System Frameworks Application OS Services Virtualized Instance Hardware High-speed network Google Apps Microsoft BPOS
- 15. Platform as a Service (PaaS) Operating System Frameworks Application OS Services Virtualized Instance Hardware High-speed network Google AppEngine Windows Azure Your responsibility Your responsibility
- 16. Infrastructure as a Service (IaaS) Operating System Frameworks Application OS Services Virtualized Instance Hardware High-speed network Amazon EC2 VMware Your responsibility
- 17. Many Players in the Game • To name a few – SaaS: Microsoft, Salesforce, Zimra, Oracle, Cisco, Google Apps – PaaS: Microsoft, Force.com, Spring Source, Google App Engine – IaaS: Amazon, IBM, VMware • Expect change, the cloud is just beginning… • In the future expect to see all large vendors riding the complete stack
- 18. Geo-Distributed Datacentres • Larger vendors have proven track records for running services for large numbers of customers – Hosted in their own datacentres
- 19. An example of SaaS Let’s look at Microsoft BPOS
- 20. Microsoft Business Productivity Online Suite (BPOS) • Two service offerings BPOS Standard and BPOS dedicated BPOS Enterprise Email Team Collaboration Web Conferencing Real-time Communications Hosted and managed by Microsoft in Microsoft Data Centers. Runs on PCs, smart phones and web browsers.
- 21. BPOS-D BPOS-D managed network Microsoft managed network Co-located domain controllers WAN termination M S O D a t a C e n t r e WAN Cloud Customer network BPOS-D client network Internet Can be enabled or disabled / application
- 22. What We Get With SaaS • Lower capital expenditure • Fixed operational costs • Scalability • Reclaimed real estate • Innovation – Many vendors will have a forever green policy • Make sure it’s not forever beta • Lower carbon footprint – Reduced power and cooling • Agility – Customers get new services in months rather than years
- 23. What To Watch • You are relinquishing control and responsibility to the vendor by moving the service to the Cloud • For this to be a valid business proposition you must TRUST the vendor to deliver what they say they will – Financial penalties for failing to meet SLA are normally equated to service credits • May well be much less value than your business loss due to a failure • Many solutions appear attractive because of the bottom line pay/user price – Buyer beware!
- 24. Your Security Posture Changes Policies, Procedures and Governance Physical Security Perimeter Data Application Machine Virtualisation Network Identity Host IaaS provider PaaS provider SaaS provider Abstracted Storage
- 25. Does Their Security Match Your Requirements? • For 9X% of organizations, the Cloud providers probably offer better – Physical security – Policies, operational procedures and governance – And where supplied, OS and application updates • In most cases you will not be allowed to audit this – You will have to trust that they operate to the standards that they state • This may be backed by a yearly independent audit, ask to see it
- 26. Data Compliance is Paramount • How and where is it stored? • How is it backed up and restored? • Is data archived and what are the retention and disposal policies? – Do you have an on-premise policy? • Is access audited and can you view the logs? • What are the breach notification procedures? – Will they help you if litigation ensues • Does the provider match your legal and compliance requirements?
- 27. It’s Up to You • Just a few topics to get you thinking – There’s more… • Only you will know if a Cloud solution is going to meet the security requirements of your organization Before you say NO Remember, security is about the pragmatic balance between keeping the bad guys out and allowing your organisation to be agile and operational efficient
- 28. My Final Tip • Negotiate the contract and SLA from a position of strength – Know exactly what’s on offer • Don’t assume that because you can do something with an on-premise enterprise application it will be available via the Cloud • Read the small print “Downtime Period” means, for a domain, a period of ten consecutive minutes of Downtime. Intermittent Downtime for a period of less than ten minutes will not be counted towards any Downtime Periods Google SLA
- 29. An example of PaaS Let’s look at Microsoft Azure
- 30. A Typical Application Web layer Request Business layer Database Response Browser What do we do when it starts to overheat? Web layer Request Business layer Database Response
- 31. Scale Out • How much is that going to cost you? – Do you need it all the time? • How long will it take you? • Do you have the capital expenditure budget? Web layer Request Business layer Database Response Web layer Web layer Web layer Web layer N L B Business layer Business layer Business layer Business layer N L B
- 32. Azure • Pay per role instance • Add and remove instances based on demand – Elastic computing! – Load balancing is part of the Azure fabric and automatically allocated Web Role Request Worker Role Database Response Browser Communications via Queues and Tables Web Role Web Role Web Role Worker Role Worker Role Worker Role Longer running processes
- 33. Compute Model Request Worker Role Response Client Worker Role Worker Role Distribute task Database Web Role

- 35. Storage On-Premise: Tight relationship between process and storage Process Storage The Cloud abstracts the data Client / Worker Role Azure Blob Storage GET http://accountname.blob.core.windows.net/containername/blobname Downloads a blob and associated metadata Max blob size 64MB, metadata 8K / blob
- 36. Azure Storage Azure Table Storage Provides structured and semi-structured data storage capabilities Client / Worker Role SQL Azure On-Premise application Worker Role On-Premise SQL Database synchronization TDS TDS
- 37. What We Get With PaaS • An elastic computing platform • Connect from anywhere, with any device • Low barrier costs to deploying new applications – Rapid provisioning • Pay as you go – Operational costs directly related to profit • A marketplace through which to sell our services – Customers continue to pay as long as they use our services – Stop paying, stop providing service • No chance of licence abuse
- 38. What To Watch • Check your security policies can be satisfied by the Cloud provider • Does the SLA meet availability requirements? • Don’t just port an existing app that have been sitting within your security perimeter – Make sure it has been engineered for Internet security • Follow Security Development Lifecycle (SDL) best practices
- 39. IaaS Virtualized Instance Hardware Public Cloud Virtualized Instance Hardware Private Cloud Virtualized Instance Hardware On-premise V2V V2V P2V P2V P2V Staged or direct migration
- 40. What to Watch? • Check your security policies can be satisfied by the Cloud provider • Does the SLA meet availability requirements? • You are now porting your OS and upper stack – You will need to maintain it Remember the Cloud is its infancy It’s immature We all have lots to learn
- 41. So everything is in the Cloud What do we do? Innovate
- 42. Reframe Your Thinking CRM Stop thinking about applications running on servers Ordering Invoicing CRM Ordering invoicing Think of them as pay on demand services Use the best of breed Communications Social Networking Business forecasting Rapidly add and try new functionality
- 43. New Business Opportunities ? Test out new ideas with small upfront costs If you need to scale rapidly, you can More operational cost = More profit Can you sell in-house expertise by packaging as a service?
- 44. Federate Identity • We need to have an Identity that will be trusted everywhere • Come to my session at 1:30 today on Active Directory Federation Services
- 45. Should We Move To The Cloud? Can we afford not to? “By 2012, 80% of Fortune 1000 enterprises will be using some cloud computing services, 20% of businesses will own no IT assets.” “The bottom line: Early adopters are finding serious benefits, meaning that cloud computing is real and warrants your scrutiny as a new set of platforms for business applications.”
- 46. So What is Cloud Computing? It’s a utility Providing us with New ways of working A chance to innovate A new market place
