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 4 megabytes of RAM to run Windows 3.0. With each new release of Windows, RAM requirements increased. Windows 98 required 16MB, while Windows XP demanded 64MB of RAM, and for best results, Microsoft recommended 128MB. Windows 7 needs at least 1 gigabyte of RAM for the 32-bit version, and 2GB...

Managing the Unmanageable

Every now and then you can hear that some bank has gone bankrupt, that some company is insolvent, and there are even entire countries that go bankrupt now. It has become a global epidemic, primarily caused by the great economic crisis that the world has not yet fully recovered from. In order to understand what can be done, we must first understand what is bankruptcy. What does it mean to be bankrupt? Some people imagine that the state of bankruptcy is the same as having no money, or, in plain words, being penniless. However, this is not the case. Being penniless means that you ha... (more)

Darkleach of Apache Web Servers

In the recent past, the website of the LA Times was compromised. At the same time, the blog site of Seagate, a renowned hard disc manufacturer, was also compromised. A closer scrutiny revealed that Apache web server program was being used to host both sites. A module was found to be the trigger in both cases. It allowed the insertion as well as the rotation of malicious iFrames. These affected all the website pages hosted through the servers. This particular iFrame is famed for redirecting users to other websites that host exploit kits. This will particularly target "Blackhole" h... (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)

Cloud Computing: A Comparison of Computing Models

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 intro... (more)
