Revolution of Cloud Computing?

What is cloud computing?

Cloud computing is the delivery of various services through the internet which provides server storage, database, networking, and software or it is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user.

Confinement of cloud computing

During the 1960s, the initial concepts of time-sharing became popularized via RJE (Remote Job Entry). In the 1990s, telecommunications companies, who previously offered primarily dedicated point-to-point data circuits, began offering virtual private network (VPN) services with comparable quality of service, but at a lower cost. By switching traffic as they saw fit to balance server use, they could use overall network bandwidth more effectively. They began to use the cloud symbol to denote the demarcation point between what the provider was responsible for and what users were responsible for. Cloud computing extended this boundary to cover all servers as well as the network infrastructure.

History of cloud computing

At the time of popularization of Amazon.com people Were get attracted towards the cloud computing services. The cloud symbol was used to represent the networks of computing-related equipment�s such as storage, Database, Networking in the original Advanced Research Projects Agency Network (ARPANET)

2000�s :- In July 2002, Amazon created subsidiary Amazon Web Services, with the goal to "enable developers to build innovative and entrepreneurial applications on their own". In March 2006 Amazon introduced its Simple Storage Service (S3), followed by Elastic Compute Cloud (EC2) in August of the same year. These products pioneered the usage of server virtualization to deliver Infrastructure as a service (IaaS) at a cheaper and on-demand pricing basis.

Service models of cloud computing:

There are three main service models for Cloud Computing.

  1. Infrastructure as a Service (IaaS)
  2. Platform as a service (PaaS)
  3. Software as a service (SaaS)
Infrastructure as a Service (IaaS)

"Infrastructure as a service" (IaaS) refers to online services that provide high-level APIs used to abstract various low-level details of underlying network infrastructure like physical computing resources, location, data partitioning, scaling, security, backup, etc. A hypervisor runs the virtual machines as guests.

Platform as a service (PaaS)

The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment.

Some integration and data management providers also use specialized applications of PaaS as delivery models for data. Examples include iPaaS (Integration Platform as a Service) and dPaaS (Data Platform as a Service). iPaaS enables customers to develop, execute and govern integration flows.

Software as a service (SaaS)

The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Emerging trends of cloud computing

Cloud computing is still a subject of research.[140] A driving factor in the evolution of cloud computing has been chief technology officers seeking to minimize the risk of internal outages and mitigate the complexity of housing network and computing hardware in-house. Major cloud technology companies invest billions of dollars per year in cloud Research and Development. For example, in 2011 Microsoft committed 90 percent of its $9.6 billion R&D budget to its cloud. Research by investment bank Centaur Partners in late 2015 forecasted that SaaS revenue would grow from $13.5 billion in 2011 to $32.8 billion in 2016.

In 2021, software as a service (SaaS) still will be the largest market segment for end-user cloud IT spending � it�s expected to grow approximately 16 percent to $117.8 billion � application infrastructure services (PaaS) is expected to grow at a higher 26.6 percent rate to about $55.5 billion, according to Gartner.
