A quick and easy lesson on some cloud computing basics
Cloud Computing Basics for Everyone
You have taken every precaution. You’ve done the research on the highest quality computer system for your business and you want to embrace the latest technology i.e. the cloud. Yet security concerns linger. What you need to do is apprise yourself of information about this new technology. A primer on cloud computing basics will put your concerns to rest.
Cloud is the slang term for computing that is internet-based. Large groups of remote servers are networked to allow the centralized storage of data. Organizations have online access to computer services or resources. The origin of the concept dates back to the 1950s when users began to share mainframes via terminals. In the 1990s, telecommunications companies offered virtual private network services which were more efficient and cheaper to use. Since 2000, companies have begun to switch from company-owned hardware to pay-per-use service-based models with more options. The benefits of cloud are lower costs and more efficiency. One example of cloud is the email available from Yahoo and Gmail. All you need is an internet connection and all your files are accessible from anywhere. Backup services are available from Microsoft and Amazon as well as others, sometimes for free.
There are two types of cloud: Software-as-a-service (SaaS) and Infrastructure-as-a-service (IaaS). With the former, the cloud company allows you to use its servers; with the latter, the company supplies the servers and infrastructure to you.
Secondly, these two types have different payment plans. SaaS generally requires payment every month, whereas IaaS operates on a pay-as-you-go basis. IaaS offers a little more responsiveness and flexibility.
Responsibilities also differ between the two. With IaaS you will need to install and maintain the operating system and application or virtual machine; the provider merely manages the infrastructure for you.
What you learn in tutorial on cloud computing basics is what is appropriate for you and your needs. You should never buy a system or service for its own sake, no matter what the programmers say. Always keep your eye on the bottom line and how the available technology can serve you.
That said, these new services are very dynamic and allow companies to more or less quickly adjust capacity to match current business trends.
Cloud computing basics also teach that even with the latest developments, system failure is an inevitability. With cloud, you will never lose the data upon which your organization depends.
