For many small businesses, the term “cloud computing” is either nebulous or associated with concerns over data security and safety.
However, there is no lack of small entrepreneurs who have sworn to the benefits that can be derived from the technology, including savings in software expenses, higher work productivity, and more efficient coordination of workflow.
Here, from forbes.com and webopediacom are some basics on cloud computing which small business owners may find useful in determining whether or not to go for this technology option.
- First of all, a definition. Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. Cloud computing is comparable to grid computing, a type of computing where unused processing cycles of all computers in a network are harnesses to solve problems too intensive for any stand-alone machine.
In cloud computing, the word cloud (also phrased as “the cloud”) is used as a metaphor for “the Internet,” so the phrase cloud computing means “a type of Internet-based computing,” where different services — such as servers, storage and applications — are delivered to an organization’s computers and devices through the Internet.
- There are two versions of cloud to know about
There are several varieties of cloud computing services. Depending on your company’s IT needs, you might be able to use a cloud service instead of investing in new IT hardware. Two of the more popular versions of cloud offerings are Software-as-a-Service (SaaS) and Infrastructure-as-a-Service (IaaS). With SaaS, the cloud service provider hosts your enterprise applications and associated data on its servers and storage systems. Users gain access to SaaS applications using a Web browser. And your company would typically pay a fee per user per month. With IaaS, the provider offers virtual machines, physical servers, storage, switching, and connectivity resources to run your enterprise applications on a pay-as-you-go basis. You are responsible for installing and maintaining the operating system and application or virtual machine; the provider is responsible for managing the infrastructure hardware that the applications or virtual machines run on.
- Cloud Computing Services offer greater flexibility in delivering IT services
Business today is very dynamic. Cloud services let companies quickly ramp capacity up AND down to match business needs.
In contrast to legacy hosting services, which often locked companies into contracts for multiple months or years, today’s cloud computing services are offered by the month or based on the consumption of resources. This is a perfect match for some industries, such as retail and financial services, which are subject to boom times and quiet times in their normal business cycles. Maybe you have a new application and are unsure of the speed of growth. A cloud computing service lets you expand and contract IT resources in sync with those cycles.
- Cloud computing gives you the ability to refresh an aging infrastructure without incurring CAPEX costs.
This is critical especially for companies that are trying to accommodate new technologies. For instance, many companies today are virtualizing their mission-critical applications. To do so, they need the virtual machines associated with those applications to run on powerful and resilient servers. Cloud computing gives companies a way to do this without having to buy new servers.
- Cloud is an economical way to support more users and new IT services.
Many data centers are running out of space. This is forcing some companies to build new data centers or pay a fortune to expand their existing centers. Here again, cloud computing allows companies to move their applications to a provider’s infrastructure and save the cost of a data center expansion.
- Cloud frees up staff for other projects.
IT staff members spend most of their time keeping the proverbial “lights on.” A good portion of an IT staff’s time is dedicated to managing, maintaining, and troubleshooting equipment. Cloud computing providers often offer infrastructure as well as management services, allowing companies to offload those tasks to the provider, thus freeing up IT staff to work on other projects that are more critical to the success of a business.
Cloud computing can be many things to different companies. The great thing about cloud computing is that the services can help companies be more responsive to market conditions, all while reining in IT costs.
