  25. 25. Cloud Vendor <ul><li>“ Cloud Vendor” is a virtual organization (may/may not own any infrastructure, platform or software) – it will use resources from various vendors and original providers (OCP – Original Cloud Providers) to offer services that meet certain service level agreements (SLA) with guaranteed Quality of Expectation (QoE) and Quality of Service (QoS) </li></ul>Cloud Computing - /50
  26. 26. Clouds and SOA <ul><li>SOA is the architecture of Cloud Computing </li></ul><ul><li>Physical infrastructure like SOA must be discoverable, manageable and governable </li></ul>Cloud Computing - /50
  27. 27. IaaS <ul><li>Rather than purchasing servers, software, data center space or network equipment, clients instead buy those resources as a fully outsourced service. The service is typically billed on a utility computing basis and amount of resources consumed (and therefore the cost) will typically reflect the level of activity. It is an evolution of virtual private server offerings </li></ul><ul><li>Cloud infrastructure services or &quot;Infrastructure as a Service (IaaS)&quot; delivers computer infrastructures like, </li></ul><ul><ul><li>Processors/CPUs </li></ul></ul><ul><ul><li>Memory </li></ul></ul><ul><ul><li>Storages </li></ul></ul><ul><ul><li>Networking </li></ul></ul>Cloud Computing - /50 Source: Wikipedia

  29. 29. PaaS <ul><li>Cloud platform services or &quot;Platform as a Service (PaaS)&quot; deliver a computing platform and/or solution stack as a service, often consuming cloud infrastructure and sustaining cloud applications. It facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers </li></ul>Cloud Computing - /50 Source: Wikipedia
  30. 30. SaaS <ul><li>Cloud application services or &quot;Software as a Service (SaaS)&quot; deliver software as a service over the Internet, eliminating the need to install and run the application on the customer's own computers and simplifying maintenance and support. Key characteristics include: </li></ul><ul><ul><li>Network-based access to, and management of, commercially available (i.e., not custom) software </li></ul></ul><ul><ul><li>Activities that are managed from central locations rather than at each customer's site, enabling customers to access applications remotely via the Web </li></ul></ul><ul><ul><li>Application delivery that typically is closer to a one-to-many model (single instance, multi-tenant architecture) than to a one-to-one model, including architecture, pricing, partnering, and management characteristics </li></ul></ul><ul><ul><li>Centralized feature updating, which obviates the need for downloadable patches and upgrades. </li></ul></ul>Cloud Computing - /50 Source: Wikipedia
  31. 31. Cloud Challenges Cloud Computing - /50

  38. 38. Service Quality and Charging <ul><li>Journaling is necessary to record usage history </li></ul><ul><li>Journaling is a critical part of any secured and reliable system </li></ul><ul><li>Journaling helps a system to recover from failure through either roll-back or roll-forward </li></ul><ul><li>Usage records are used at a later time to charge and bill a consumer </li></ul><ul><li>Journaling is also used for forensic purposes to recreate the crime scene of a security attack </li></ul>Cloud Computing - /50
  39. 39. Scalability and Availability <ul><li>Scalability in the cloud applications needs to be dynamic </li></ul><ul><li>Applications need to react to external events such as increased load, augmented reliability etc </li></ul><ul><li>In the cloud, there will be no association between the service and the underlying platform and infrastructure </li></ul><ul><li>The cloud user / customer may like to use some resource somewhere in the world that offers the best price performance advantage </li></ul>Cloud Computing - /50
  40. 40. Location of Data <ul><li>This is important issue that should be considered in the cloud environment. There are laws related to both what can be stored and what can be transferred (into and out of) countries. Some country’s laws say that the data should not be stored outside of the country. </li></ul>Cloud Computing - /50
  41. 41. Multi Tenancy <ul><li>This is resultant of virtualization, where two or more cloud vendors share the same resource from an original cloud provider. There should be clean and clear way to ensure that other tenants are not gaining access to other parties’ data. This is also called data anonymity . </li></ul>Cloud Computing - /50
  42. 42. Business Continuity and Data Retention <ul><li>Cloud vendors have data recovery and business continuity plans in place to ensure that service can be maintained in case of a disaster or an emergency and that any data lost will be recovered. These plans are shared with and reviewed by their customers so that business continues even if the cloud vendor/provider goes out of business. </li></ul>Cloud Computing - /50
  43. 43. Data Protection <ul><li>This is to ensure that only the authorized and legitimate users access or stored data in the cloud. Also, if necessary, the country where the data is hosted can be examined by the law enforcement agencies. </li></ul><ul><li>HIPPA (Health Insurance Portability and Accountability Act) in the US also prohibits certain types of access on healthcare data. </li></ul><ul><li>Sarbanes Oxley demands certain types of accounting practices to be followed be enterprises. </li></ul><ul><li>On 5th February 2010, the European Commission has adopted a decision updating the standard contractual clauses for the transfer of personal data to processors established in non-EU countries that are not recognised as offering an adequate level of data protection. </li></ul><ul><li>The USA Patriot Act was passed that allows certain government organizations to examine any data within USA. </li></ul><ul><li>RIPA (The Regulation of Investigatory Powers Act) can be invoked by the UK government officials specified in the Act on the grounds of national security. Compliance environments that experts cite as important for cloud computing included auditing-related standard SAS 70, </li></ul><ul><li>Payment Card Industry Data Security Standards (PCI DSS) and FISMA. </li></ul>Cloud Computing - /50
  44. 44. Accounting Logs & Audit Trails <ul><li>In addition to producing logs and audit trails, cloud vendors (providers) work with their customers to ensure that these logs and audit trails are properly secured, maintained for as long as the customer requires, and are accessible for the purposes of forensic investigation (e.g., eDiscovery). </li></ul>Cloud Computing - /50
  45. 45. Which Laws Apply <ul><li>Another considerable issue is which laws apply? An example a client based in USA, using cloud services of a company registered in Europe and having services in Asia. These are issues that need to be clarified and understood clearly. It will be difficult for a service provider to provide conformance to all international standards and be economical at the same time. Further there might be instances when it will just not be possible to confirm to all as there may contrasting views. </li></ul>Cloud Computing - /50
  46. 46. Legal and Contractual Issues <ul><li>Aside from the security and compliance issues enumerated above, cloud providers and their customers will negotiate terms around liability (stipulating how incidents involving data loss or compromise will be resolved, for example), intellectual capital, and end-of-service (when data and applications are ultimately returned to the customer). </li></ul>Cloud Computing - /50
  47. 47. Taxation & Regulatory Issues <ul><li>The Cloud-vendor will be a company with Tax registration on the country of operation </li></ul><ul><li>The Original Cloud Provider will be taxed on the country of operation – some tax benefits will be there for export of service </li></ul><ul><li>Regulatory authorities will ensure that data privacy and data transportation related policies are enforced </li></ul><ul><li>No matter what the customers want, Cloud Provider must conform to the law of the land </li></ul>Cloud Computing - /50
