Cloud Elasticity or Scalability, Whats the Difference?
I have heard and read at lot of places about Elasticity and Scalability of the cloud. In a discussion the point came across that what actually is the difference between Elasticity and the Scalability, when it comes to cloud. I myself could not find the demarcation, so I searched around the web. But to my surprise lot of people on the articles conviniently use Elasticity and Scalability interchangeably in relation the cloud. After reading around I could not find the answer, so I though to put my own thoughts since I dont agrre that both is same and let people decide if my understanding is right or not. What means by Elasticity in relation to cloud is that it could scale up or down the infrastructure to meet the requirement.
