NIST Other types of delivery models Summary
- 2. 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
- 3. 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.
- 4. 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
- 5. 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.
- 6. 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.
- 7. 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.
- 8. 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.
- 9. 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.
- 10. 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.
- 11. 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.
- 12. 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.
- 13. 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.
- 14. 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.,
- 15. 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.
- 16. 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 its making enterprises more efficient.
- 17. 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.
- 18. 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.
- 19. 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.
