  8. 8. The Cloud Computing architecture comprises of many cloud components, each of them are loosely coupled. We can broadly divide the cloud architecture into two parts: Front End refers to the client part of cloud computing system. It consists of interfaces and applications that are required to access the cloud computing platforms, e.g., Web Browser. Back End refers to the cloud itself. It consists of all the resources required to provide cloud computing services. It comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc.
  9. 9. Development Models  Public  Private  Hybrid  Community Service Models  SaaS  PaaS  IaaS
  10. 10. Public Cloud Private Cloud Hybrid Cloud Community Cloud
  11. 11. Public Cloud allows systems and services to be easily accessible to general public, e.g., Google, Amazon, Microsoft offers cloud services via Internet.
  12. 12. Private Cloud allows systems and services to be accessible with in an organization. The Private Cloud is operated only within a single organization. However, It may be managed internally or by third-party.
  13. 13. Hybrid Cloud is a mixture of public and private cloud. Non-critical activities are performed using public cloud while the critical activities are performed using private cloud.
  14. 14. Community Cloud allows system and services to be accessible by group of organizations. It shares the infrastructure between several organizations from a specific community. It may be managed internally or by the third- party.
  15. 15.  Software as a Service (Saas)  Platform as a service (PaaS)  Integration/infrastructure as a Service (IaaS)
  16. 16.  When an organization is considering Cloud security it should consider both the differences and similarities between these three segments of Cloud Service Models
  17. 17. This particular model is focused on managing access to applications. For example, policy controls may dictate that a sales person can only download particular information from sales CRM applications(Customer Relationship Management). For example, they are only permitted to download certain leads, within certain geographies or during local office working hours. In effect, the security officer needs to focus on establishing controls regarding users' access to applications.
  18. 18. The primary focus of this model is on protecting data. This is especially important in the case of storage as a service. An important element to consider within PaaS is the ability to plan against the possibility of an outage from a Cloud provider. The security operation needs to consider providing for the ability to load balance across providers to ensure fail over of services in the event of an outage. Another key consideration should be the ability to encrypt the data whilst stored on a third-party platform and to be aware of the regulatory issues that may apply to data availability in different geographies
  19. 19. Within this model the focus is on managing virtual machines. The CSOs (Chief Security Officers) priority is to overlay a governance framework to enable the organization to put controls in place regarding how virtual machines are created uncontrolled access and potential costly wastage
  20. 20. Many Cloud services are accessed using simple REST Web Services interfaces. These are commonly called "APIs", since they are similar in concept to the more heavyweight C++ or Java APIs used by programmers, though they are much easier to leverage from a Web page or from a mobile phone, hence their increasing ubiquity Does not access private user data
  21. 21. CSOs focused on SaaS, PaaS and IaaS all the time.
  22. 22. BENIFITS High Efficiency Reliability & Flexibility Manipulate & configure apps online Cost Effective No software Required On Demand self service Online Development Resources Available on Network Applications as utilities over Internet
  23. 23. Virtualization Service-Oriented Architecture (SOA) Grid Computing Utility Computing
  24. 24. Virtualization is a technique, which allows to share single physical instance of an application or resource among multiple organizations or tenants (customers). It does so by assigning a logical name to a physical resource and providing a pointer to that physical resource when demanded
  25. 25. Service-Oriented Architecture helps to use applications as a service for other applications regardless the type of vendor, product or technology.
  26. 26. Grid Computing refers to distributed computing in which a group of computers from multiple locations are connected with each other to achieve common objective. These computer resources are heterogeneous and geographically dispersed
  27. 27. Utility computing is based on Pay per Use model. It offers computational resources on demand as a metered service. Cloud computing, grid computing, and managed IT services are based on the concept of Utility computing.
  28. 28. Although Cloud Computing is a great innovation in the world of computing, there also exist downsides of cloud computing. It is the biggest concern about cloud computing. Since data management and infrastructure management in cloud is provided by third-party, it is always a risk to handover the sensitive information to such providers. Although the cloud computing vendors ensure more secure password protected accounts, any sign of security breach would result in loss of clients and businesses.
  29. 29. Security and Privacy of information is the biggest challenge to cloud computing. Security and privacy issues can be overcome by employing encryption, security hardware and security applications. PORTABILITY INTEROPERABILITY COMPUTING PERFORMANCE RELIABILITY AND AVAILABILITY
  30. 30. It is very difficult for the customers to switch from one Cloud Service Provider (CSP) to another. It results in dependency on a particular CSP for service. This risk involves the failure of isolation mechanism that separates storage, memory, routing between the different tenants
  31. 31. Encryption helps to protect data from being compromised. It protects data that is being transferred as well as data stored in the cloud. Although encryption helps to protect data from any unauthorized access, it does not prevent from data loss.
  32. 32. Data Security and Privacy Requirement Budget Requirements Type of cloud - public, private or hybrid Data backup requirements Training requirements Dashboard and reporting requirements Client access requirements Data export requirements
