What it is:
Cloud Computing is an IT service intended for business use that vendors such as Salesforce.com, Rackspace and WebSense offer "on-demand." Vendors provide "on-demand" services such as CRM, off-site storage, hosted email solutions, secure web portals, etc. Instead of spending money on applications and hardware, businesses have access to the same resources without the commitment of ownership.
Where it's located:
Because services are provided over the internet, the vendor can be located anywhere in the world and it won't impact quality of service. Businesses can access most purchased solutions through a secure device such as a workstation, laptop or smartphone and a web browser such as Internet Explorer or Firefox.
While each cloud computing vendor will operate with a slightly different business plan, all vendors do share similarities.
- Affordable- As an "on-demand" service, vendors will only charge businesses for the resources used. Typically, you will sign a contract of some sort, but the terms are flexible and should meet your business needs.
- Scalable- Most vendors provide cloud computing services to organizations of any size. Your business will not be restricted by its number of users or amount of data.
- Self-service- While vendors will maintain the hardware and the solution, your business will be responsible for maintaining all data.
- Multi-tenancy- Vendors store data from multiple companies on the same hardware. Don't worry; your business' data will be kept separate and secure through application architecture, while sharing resources such as storage, memory and processing power.
- Redundant data storage- Most solutions provide multiple physical sites where they will store multiple copies of data, making cloud computing suitable for businesses that need high-availability.
Every business that uses cloud computing solutions will realize many benefits. While some benefits will be particular to your individual business, two key benefits that all businesses realize are as follows:
- No out-of-pocket infrastructure costs- With cloud computing, your business won't need to buy additional servers, hardware or networking equipment to take advantage of a solution.
- Simple to support- Vendors will service and support their solution, upgrading and patching your solution so you don't have to.
