The document discusses cloud computing, defining it as a model for on-demand access to shared computing resources with various deployment and delivery models. It highlights the advantages of using cloud services, such as cost savings and agility, while addressing concerns about security and privacy. The future of cloud computing is predicted to see rapid adoption and growth, with a focus on Platform as a Service (PaaS) and the importance of balancing risks to fully leverage cloud benefits.

7. Cloud Computing - DefinitionOn-demand self-service internet infrastructure where you pay as you go and use only what you need, all managed by a browser, application or APIClouds will be the next transformation over the next several years, building off of the software models that virtualization enabled+ 100s more from experts, vendors and kids

8. NIST Definition of Cloud ComputingCloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

31. Mental ShiftLosing ControlTrust

32. In RealityCloud is neither more nor less secure than the traditional ITWith the loss of control, different kind of risks comes into focusIndustry best practices can help mitigate these risks. Check out Cloud Security Alliance (CSA)Bottom Line is balancing the risks to take advantage of the clouds

33. Vendor Responsibility

34. Future Of Cloud ComputingCloud adoption will be rapid. Security concerns will fade away with better education on the side of the users and more transparency on the side of the providersA federated cloud ecosystem will ensure competition empowering the usersPaaS is the future of cloud services – empowering the developers

35. ConclusionCloud is real and maturing fast. Businesses of all sizes and shapes are going to adopt it much sooner than many expectUsing Cloud Computing becomes a competitive advantageA big part of the security concerns are due to FUD but it is also critical to understand the risks and take steps to mitigate them, to take the full advantage of cloudsLeverage the cloud but control your destiny
