Why is it called \u2018The Cloud\u2019?<\/strong><\/p>\n\n\n\n

\u201cThe Cloud\u201d started off as a tech industry slang term. In the early days of the Internet, technical diagrams often represented the servers and networking infrastructure that make up the Internet as a cloud. As more computing processes moved to this servers-and-infrastructure part of the Internet, people began to talk about moving to \u201cthe cloud\u201d as a shorthand way of expressing where the computing processes were taking place. Today, \u201cthe cloud\u201d is a widely accepted term for this style of computing.<\/p>\n\n\n\n

For businesses, switching to cloud computing removes some IT costs and overhead: for instance, they no longer need to update and maintain their own servers, as the cloud vendor they are using will do that. This especially makes an impact for small businesses that may not have been able to afford their own internal infrastructure but can outsource their infrastructure needs affordably via the cloud. The cloud can also make it easier for companies to operate internationally because employees and customers can access the same files and applications from any location.<\/p>\n\n\n\n

Cloud Computing Overview<\/strong><\/p>\n\n\n\n

Cloud computing is possible because of a technology called virtualization. Virtualization allows for the creation of a simulated, digital-only \u201cvirtual\u201d computer that behaves as if it were a physical computer with its own hardware. The technical term for such a computer is a virtual machine (VM). When properly implemented, virtual machines on the same host machine are sandboxed from one another, so they don\u2019t interact with each other at all, and the files and applications from one virtual machine aren\u2019t visible to the other virtual machines even though they\u2019re on the same physical machine.<\/p>\n\n\n\n

Virtual machines also make more efficient use of the hardware hosting them. By running many virtual machines at once, one server becomes many servers, and a data center becomes a whole host of data centers, able to serve many organizations. Thus, cloud providers can offer the use of their servers to far more customers at once than they would be able to otherwise, and they can do so at a low cost.<\/p>\n\n\n\n

Even if individual servers go down, cloud servers, in general, should be always online and always available. Cloud vendors generally back up their services on multiple machines and across multiple regions.<\/p>\n\n\n\n

Users access cloud services either through a browser or through an app, connecting to the cloud over the Internet \u2013 that is, through many interconnected networks \u2013 regardless of what device they\u2019re using.<\/p>\n\n\n\n

Advantages of Cloud Computing<\/strong><\/p>\n\n\n\n

Cost Shift<\/em><\/p>\n\n\n\n

The financial challenge for any business organization of an on-premises infrastructure is the CAPEX (Capital Expenditure) that goes into creating, fixing, and updating the hardware in it, often involving substantial over-provisioning of resources. This is in addition to the OPEX (Operational Expenditure) of energy bills and paying personnel to operate and monitor the infrastructure.<\/p>\n\n\n\n

Using the cloud reduces the CAPEX costs, replacing them with OPEX costs as part of the service subscription. This means that costs better reflect actual infrastructure use and infrastructure upgrade costs can be more easily absorbed into operating budgets.<\/p>\n\n\n\n

Scalability<\/em><\/p>\n\n\n\n

When a company is subscribed to a cloud service, it can easily scale resources up and down as needed.<\/p>\n\n\n\n

Resource Management<\/em><\/p>\n\n\n\n

Cloud computing and networking allow companies to improve resource management from infrastructure to personal. Resources can be procured, paid for, and used with greater specificity. Monitoring tools allow organizations to watch resource use and adjust their usage so they aren\u2019t paying for unused resources. <\/p>\n\n\n\n
