Benefits of Virtualization
Virtualization can increase IT agility, flexibility, and scalability while creating significant cost savings. Workloads get deployed faster, performance and availability increases and operations become automated, resulting in IT that's simpler to manage and less costly to own and operate. Additional benefits include:
- • Reduce capital and operating costs.
- • Minimize or eliminate downtime.
- • Increase IT productivity, efficiency, agility and responsiveness.
- • Provision applications and resources faster.
- • Enable business continuity and disaster recovery.
- • Simplify data center management.
- • Build a true Software-Defined Data Center

Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics, and more—over the Internet (“the cloud”). Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you’re billed for water or electricity at home. Still foggy on how cloud computing works and what it’s for? This beginner’s guide is designed to demystify basic cloud computing jargon and concepts and quickly bring you up to speed.
Uses of cloud computing
You’re probably using cloud computing right now, even if you don’t realize it. If you use an online service to send email, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files, it’s likely that cloud computing is making it all possible behind the scenes. The first cloud computing services are barely a decade old, but already a variety of organizations—from tiny startups to global corporations, government agencies to non-profits—are embracing the technology for all sorts of reasons. Here are a few of the things you can do with the cloud:
- • Create new apps and services
- • Store, back up, and recover data
- • Host websites and blogs
- • Stream audio and video
- • Deliver software on demand
- • Analyze data for patterns and make predictions
The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same system. A server host runs one or more server programs which share their resources with clients. A client does not share any of its resources, but requests a server's content or service function. Clients therefore initiate communication sessions with servers which await incoming requests. Examples of computer applications that use the client–server model are Email, network printing, and the World Wide Web.
Sooner or later, your small business will need more space for data storage. Information in the form of e-mails, documents, presentations, databases, graphics, audio files and spreadsheets is the lifeblood of most companies, and the applications that run and protect your business require a lot of disk space. In addition, a number of trends are fueling our growing hunger for storage:
Storing information and managing its storage is critical to a company's behind-the-scenes success. Fortunately, there are many options available to small businesses for both the actual storage and the location of that storage. Often, the best solution is a combination of different storage options.
So how do you decide what's best for you? First, you'll want to consider your storage needs in terms of both capacity and physical location. Then you should look at the storage options that best fit those needs. Lastly, you need to develop a plan for implementing your chosen storage solutions.
