A simple definition of cloud computing is that it's a unique storage service that involves storage of data and software. With cloud computing, the person or company who enjoys the service is not fully aware of the location, storage facilities or configuration of the system used to offer the storage services. A good analogy to explain this concept is the regular power grid that supplies power to homes and businesses. The end user who enjoys the services is hardly aware of all the power generation and distribution devices and components used to deliver the service. Since its introduction, cloud computing has evolved through several stages like virtualization computing to autonomic utility form of cloud computing. It has also evolved from service-oriented architecture. There are some concepts that are quite similar to cloud computing. These cloud computing comparisons... (more)

The Evolution of Computer Hardware

On a cutting-edge PC in 1990, the processor, the heart of any computer, would run at a paltry 33 megahertz. The first Pentium processor from Intel appeared in 1993, performing calculations at a then-quick clock speed of 66 MHz. The race to build faster, more capable processors continued unabated, with milestones such as 1 GHz and 3 GHz reached along the way. Today, the emphasis is on building multiple processing cores in a single chip, with Intel's second-generation Core i7 offering four cores running at 3.4 GHz. For memory, that 1990 computer would probably have relied on a mere... (more)

Cloud Computing: How It Affects Enterprise and Performance Monitoring

In recent times, cloud computing has played a dominant role in the industry. Whether you feel positively or negatively about it, it is undeniable that cloud monitoring, like any other component in your network, needs to be monitored – perhaps more than any other. To more old-fashioned solutions for monitoring, the cloud creates a number of obstacles: you do not have ownership of its hardware, it is not run on your network and when problems or glitches occur you have no control over them. Today there is a wide range of utilities to help you to manage your cloud computing, and the ... (more)
