The “cloud” is a metaphor for the amorphous space that is the Internet, which is often depicted with a cloud-shaped symbol.
Thus, cloud computing is the practice of Internet-based computing, where different services, (such as servers and apps) are regularly stored and accessed through the Internet.
What is cloud computing?
The concept of the cloud dates back to the 1950s, when mainframe computers became accessible via thin clients
The Internet was first referred to/depicted as “the cloud” in 1994
In the ‘90s, telecom companies began using VPN (virtual private network) services
After the dot-com bubble (1997-2000), Amazon played an integral part in development of cloud computing by modernizing their data centers. They launched Amazon Web Service (AWS) in 2006 to offer cloud computing to external customers
In 2008, Eucalyptus became the first open-source, AWS API-compatible platform for deploying private clouds. That same year, OpenNebula became the first open-source software for private and hybrid clouds
A brief history
The cloud, by xkcd:
Infrastructure as a service (IaaS): Provides users with server, storage and networking software. Ex: Amazon Web Service
Platform as a service (PaaS): AKA middleware. Offers users virtualized servers and operating systems so that they can create and run apps. Ex: Google Apps
Software as a service (SaaS): This is the one that we interact with most. Accessible through web browsers, this is any application that is hosted on a remote server and accessed through the Internet. Ex: Netflix
Three types of cloud computing:
Benefits: or how I learned to quit worrying and love “the
cloud”
Just a few examples of how we use the cloud daily:
GmailFacebook/YouTubeWeb site hosting companiesGoogle DocsThe App Store for iPhoneDropbox
…And it’s only going to continue to grow as more businesses adapt to the cloud.
Just a few reasons cloud computing is smart for businesses of any size:
Cost-effectiveIncrease productivity / aligns with a mobile workforceMore capacity for storageLess downtimeDecreases overhead
Benefits for businesses
Reliability Security Effects on IT industry/jobs No current regulations or standards Support
