  • Evolution of Cloud computing Definition of Cloud computing – NIST Other types of delivery models Summary
  • Grid Computing Utility Computing SaaS Computing Cloud Computing • Group of people are work together to achieve a goal • Globally distributed data and resources • Offering computing resources as a metered service • Introduced in late 1990s • Network based subscriptions to applications • Gained momentum in 2001 • Next- Generation Internet computing • Next- Generation Data Centers
  •  Cloud computing is a model for enabling convenient , on demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. View slide
  •  There are some other services in cloud computing • DaaS – Data as a service • SECaaS – Security as a service • TaaS – Testing as a service • STaaS – Storage as a service • BPaaS – Business Process as a service View slide
  •  DaaS is a cousin of Software as a service(SaaS)  DaaS is based on the concept that the data can be provided on demand to the consumer.  Data as a Service (DaaS) is a distribution model in which data files (including text, images, sounds, and videos) are made available to consumers over a network.  Data is usually located in relational databases inside corporate data centers.
  •  DaaS offers convenient and cost-effective solutions for customers.  Providers: • Xignite company that makes financial data available to customers.  Daas pricing models have two types: • Quantity-based pricing and pay-per-call (PPCall). • Data type based model.
  •  Benefits: • Ability to move data easily from one platform to another. • Global accessibility. • Comfortable to administration. • Automatic updates. • Eliminate redundancy. • Data accessibility is controlled through data services, which improves data quality.
  •  Security-as-a-service (SECaaS) is an outsourcing model for security management.  It involves application such as anti – virus software that is provided over internet to consumers.  SECaaS can be referred to as security management in cloud computing.  These security services often include anti- malware, intrusion detection, security event management etc.
  •  Providers: • Security as a Service product vendors include Cisco, McAfee etc., • McAfee was the first vendor who try to bring SECaaS to market. • Their product name is McAfee ASaP.
  •  Benefits: • Faster user provisioning. • Greater security that is available within an organization. • SECaaS solutions are provided on a monthly rental basis. • All latest updates are automatically installed.
  •  Testing as a Service (TaaS) is a model in which testing activities are performed.  TaaS is widely used and it is a popular terminology across the testing industry.  TaaS model include automated regression testing, performance testing, security testing and monitoring/testing of cloud - based applications etc.,  TaaS is sometimes known as “On – Demand testing”.
  •  The test resources are provisioned automatically to the customers.  After testing consumer can deprovisioned the resources to providers.  When ever consumer need the resource they can reprovision the resources from the providers.  Providers: • Wipro now announced that launching the TaaS to consumers.
  •  Benefits: • Standardized testing processes and the availability of additional resources increases the quality of the product. • TaaS allow testers to conduct tests at a higher load. • They can also verify that the application is suitable on various platforms, devices etc.
  •  Storage as a service (STaaS) is a business model in which a large service provider rents space in their storage infrastructure on the measured basis  Storage as a Service is often used to solve offsite backup challenges.  Storage-as-a-Service packages may include features like redundancy, scalability, support for large data objects, management, and transfer of data etc.,
  •  Providers: • Google docs 5GB (free). • Amazon cloud 5GB (free).  Benefits: • Companies find that they can save money by investing in storage-as-a-service. • No need to pay for backup tools. • We can offload the complexities associated with backups.
  •  The Business Process as a Service (BPaaS) model which originates fundamentally from the idea of outsourcing business processes.  Many enterprises are seeking third-party vendors to host business solutions rather than source the hardware and software themselves.  This is widely known as the Software-as-a-service (SaaS) model and it’s making enterprises more efficient.
  •  Any business process can be delivered as a service over the internet.  In the BPaaS environment, a vendor not only hosts its solution on behalf of the enterprise, it also takes part in managing the tool to ensure business goals are met.  The software that is related to the BPaaS is provided separately to the consumers.
  •  Benefits: • BaaS model is cost effective. • Better growth in Business results. • Support for the implementation and configuration of business process. • On demand service through a monthly and annual subscription pricing model.
  •  All the services are said together as Xaas – “Anything and Anywhere as a service”.  These all services can be buy from different providers if there is a standard API service all the services are connected easily in cloud.  The three different service models for the delivery of cloud computing IaaS, SaaS, and PaaS provide the ability to mix and match the best service model to the business needs of their organization based upon requirements and payment options.
