GenNode Labs, a genomics research company, runs large-scale DNA sequencing workloads for three days at the end of every month. The compute infrastructure remains completely idle for the other 27 days. The company is planning to migrate this workload from their on-premises data center to AWS. Which of the following options describes the primary cloud economics benefit that GenNode Labs will realize by moving to AWS?
- AThe ability to prepay for maximum compute capacity to ensure resource availability, which allows the company to convert variable operating expenses (OpEx) into upfront capital expenses (CapEx).
- BThe ability to scale the infrastructure to handle large-scale data growth over the next five years, which is the definition of cloud elasticity.
- The ability to pay only for the compute resources used during the three days of sequencing, shifting from a fixed capital expense (CapEx) to a variable operating expense (OpEx).Answer
- DThe ability to migrate the workload using a rehosting (lift-and-shift) strategy, which automatically refactors the monolithic code into microservices.
Answer
The ability to pay only for the compute resources used during the three days of sequencing, shifting from a fixed capital expense (CapEx) to a variable operating expense (OpEx).
The correct option is correct because it highlights how GenNode Labs can utilize AWS elasticity to only pay for resources when they are active. This represents the core cloud economics benefit of moving from fixed capital expenses (purchasing and maintaining physical servers that sit idle) to variable operating expenses (paying only for the runtime of the instances).
