In this blog post we I will talk about some key characteristics of a highly scalable distributed system in particular: Scalability Read Part 4 Reliability Availability Efficiency and Manageability. Scalability Scalability is the capability of a sys...
In order to understand how the the concept of cloud [unlimited computing resourcing] works, we need to understand the concepts of scalability. In other words how does computing resources scale ? Let's consider the basic simple web application softwar...
So you learned programming, you have control over the machines and can make them do what you want. Congratulations !. Now you have an idea for your very own killer application, you have thought of a very good and modern interface for it, you have sp...
