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

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)
MySQL, just like other relational databases, is complicated. It can jam at
any time jeopardizing your applications or business without notice. Most
MySQL malfunctions are due to common mistakes. It is essential to avoid these
mistakes, often hidden by configuration trap or workload, to ensure that
MySQL server runs effectively. Here are 10 tips to ensure excellent
performance of the MySQL server.
Profile your workload
Profiling the server's workload is the best way to know how the server spends
time. This exposes the most exclusive questions for tuning. Time is very
essential h... (more)
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)
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)
