Download the authoritative guide: Using the Cloud to Transform Your Business Most technology experts list cloud computing as one of the most influential IT trends of the twenty-first century. Over the past two decades, cloud computing has revolutionized enterprise IT to the point where most organizations now take a "cloud-first" approach to their technology needs.

According to the MIT Technology Reviewthe phrase "cloud computing" was probably first used in the mids at a now-defunct company called NetCentric. Then inSalesforce. Since then, cloud computing has become nearly ubiquitous among enterprises; several research reports have found that between 90 and percent of companies use at least one cloud service.

The boom in cloud has prompted great growth in related fields, particularly cloud analytics. Most experts expect the cloud computing market to continue to grow as organizations migrate more applications and data to the cloud.

Clearly, the advantages in cloud costs — the desired to trim data center costs — have driven cloud adoption. Similarly, Gartner says"The use of private cloud and hosted private cloud services is also expected to increase at least through What is Cloud Computing?

A lot of different organizations have put together definitions of cloud computing, but the definition that is probably accepted the most widely throughout the technology industry comes from the National Institute of Standards and Technology NIST at the U.

First released in Septemberthe complete cloud computing definition publication runs for seven pages and is too long to include here. It includes the following five "essential characteristics" that all cloud computing environments share: A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider.

Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms e. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction e.

Examples of resources include storage, processing, memory, and network bandwidth.

Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time.

Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service e. Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

To codify the technical aspects of what a cloud vendor provides, every customer needs a Service Level Agreement. Gartner summarizes those key points in its definition of cloud computing, which says cloud computing is "a style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service using Internet technologies.

Cloud computing represents a major generational shift in enterprise IT. Cloud Computing Services A lot of different types of a cloud services fall under the overall category of cloud computing. The NIST cloud computing definition identifies three cloud service models: Those three models continue to dominate cloud computing, but various vendors have also introduced other types of cloud services that they market with the "as a service" label.

Some people lump all these various cloud services together with the label "everything as a service" or "XaaS. Instead of paying a flat fee, as is typical with traditional software, users purchase a subscription, often on a monthly or yearly basis.

IaaS IaaS vendors provide access to computing, storage, networks and other infrastructure resources. Using an IaaS is very similar to using a server, storage appliance, networking device or other hardware, except that it is being managed as a cloud rather than as a traditional data center.

Amazon Web Services is the leading public IaaS vendor. Typically, they bundle together the tools that developers will need to write, deploy and run their own applications. For example, a PaaS might include the operating system, database, Web server, content management system and development tools that an organization might need to set up a Web application.Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics, and more—over the Internet (“the cloud”).

Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you’re billed for . Cloud computing is a type of computing that relies on shared computing resources rather than having local servers or personal devices to handle applications.

In its most simple description, cloud computing is taking services (" cloud services ") and moving them outside an organization's firewall. Yeah, just cloud computing, sorry, what Diane [Greene] has been driving. — Recode Staff, Recode, "Full transcript: Box CEO Aaron Levie on Recode Decode," 11 July Meanwhile, there are hundreds of thousands of open positions in the U.S.

Simply put, cloud computing is computing based on the initiativeblog.com in the past, people would run applications or programs from software downloaded on a physical computer or server in their building, cloud computing allows people access to the same kinds of applications through the internet.

What is CNCF? CNCF is an open source software foundation dedicated to making cloud native computing universal and sustainable. Cloud native computing uses an open source software stack to deploy applications as microservices, packaging each part into its own container, and dynamically orchestrating those containers to optimize resource utilization.
