Cloud Computing Week 2 Assignment: IaaS redundancy and load balancing
For this week’s assignment, create a paper that compares and contrasts how IaaS facilitates system redundancy and load balancing. Define and describe how you would use IaaS to facilitate redundancy and load-balancing for a business that is considering moving its infrastructure to the cloud.
Remember that load balancing may create redundancy but redundancy does not create load balancing, so you must have distinct responses for both.
Assignments should be clear and detailed, sources must be cited in APA format and must have clear organization and flow.
Assignments are expected to be a minimum of 3 pages.
