Benefits of Cloud Computing

Question 1

What are the two main considerations with deploying a cloud application?

Answer 1

Availability (the uptime of the service) and Scalability (ability to react to changing demand)

Question 2

What is the difference between Vertical Scaling vs Horizontal Scaling?

Answer 2

Vertical scaling refers to increasing the amount of resources (e.g. more RAM), while horizontal scaling refers to increasing the number of instances of resource (e.g. more VMs)

Question 3

How do cloud solutions increase reliability?

Answer 3

A decentralised network allows redundancy, meaning if one region fails, another can take over on its behalf

Question 4

How do cloud solutions provide predictability?

Answer 4

Performance needs can be predicted by tools like auto-scaling, load balancing, etc.
