Scalability in cloud computing
How do you define "scalability" in an intuitive manner? A resource is said to possess "scalability" if it can handle various tasks that you may throw at it. Let's continue working with our car analogy. Let's say that you had to deliver a package using your car. If the package fits and you can perform the task, you can confidently say that your vehicle could scale to handle the task. What if you need to haul groceries?

But as you can see, the "scalability" of your car is about to hit its limit.
In the context of computer science, "scalability" can be used in two ways:
- An application can continue to function correctly when the volume of users and/or transactions it handles increases. The increased volume is typically handled...
