Cloud Computing has become more and more affordable, it has seen an important growth in terms of adoption among all the IT companies in the last few years, overtaking the previously used on-premise solutions. Indeed, Cloud Computing is generally cheaper and easier to set-up with respect to on-premise solutions, requiring no maintenance and coming with more service stability, generally higher up-time and dedicated support from experienced companies like Google or Amazon in case of problems. The easiness of Cloud Computing, however, may lead developers to misuse computational resources mainly because it is very easy to add more memory or more processing units to any application.
