What is Cloud Computing?
Cloud computing is a new way of providing and consuming IT Services.
The National Institute of Standards and Technology (NIST) definition. There are three major cloud service models:
Infrastructure as a Service (Iaas)
Platform as a Service (Paas)
Software as a Service (Saas)
Infrastructure as a Service (IaaS)
is a form of cloud computing that provides virtualized computing
resources over the Internet. In an IaaS model, a third-party provider
hosts hardware, servers, storage, and other infrastructure components to
be consumed by its users. IaaS providers also handle tasks like system
maintenance, backup, and resiliency planning.
platforms offer highly scalable resources that can be adjusted
on-demand. This makes IaaS well-suited for workloads that are temporary,
dev, test, and production. Other characteristics of IaaS environments
include the automation of administrative tasks, as well as dynamic
scaling of servers and other resources.
Platform as a service (PaaS) is a form of cloud computing that provides development environments to application developers. The third-party provider typically develops toolkits and standards for development as well as channels for distribution. In the PaaS models, third-party providers deliver a computing platform, typically including operating system, programming-language execution environment, database, and web servers. Application
developers can develop and run their software solutions on the cloud
platform without the cost and complexity of buying and managing the
underlying hardware and software layers.
| With some PaaS offers, like Microsoft Azure and Google App Engine, the underlying computer and storage resources scale automatically to match application demand so that the cloud user does not have to allocate resources manually. The latter has also been proposed by an architecture aiming to facilitate real-time in cloud environments.|
Software as a service (SaaS) is
a form of cloud computing that provides users access to application
software and databases. The third-party cloud providers manage the
infrastructure and platforms that run the applications. SaaS is
sometimes referred to as "on-demand software" and is usually priced on a
pay-per-use basis or using a subscription fee. In
the SaaS model, third-party cloud providers install and operate
application software in the cloud and users access the software from the
Internet. This eliminates the need to install and run the application
on the user's own computer, which simplifies maintenance and support.
|Cloud applications differ from other applications in their scalability
which can be achieved by cloning tasks onto multiple cloud servers at
run-time to meet changing work demand. Load balancers distribute the
work over the set of cloud servers. This process is transparent to the
user who sees only a single access-point. To accommodate a large number
of users, cloud applications can be multitenant, meaning that any
machine may serve more than one user or organization.|
SaaS gives a
business the potential to reduce IT operational costs by outsourcing
hardware and software maintenance and support to a third-party cloud
provider. This enables the business to reallocate IT operations costs
away from hardware/software/personnel expenses and towards meeting other
goals. In addition, with applications hosted centrally, updates can be
released without user intervention.
All three of the cloud models mentioned above can be deployed on a Private, Hybrid, or Public Cloud environment.
At its essence, cloud computing is the aggregation of resources (compute, storage, and network) so that capacity requirements can be dynamically modified to match fluctuation in system workloads. This resource matching can be automated or self-provisioned by line of business (LoB) resources interacting with the cloud environment. The value proposition of cloud computing also includes agile compute infrastructure, provisioning instantaneous resources for growth, new application, and disaster recovery. Cloud computing can also readily recycle and repurpose resources into higher value computing needs.
