Answer: C
Diagrams:
The scenario blends itself into the Business Agility value proposition where new features can be deployed faster to reduce errors. The microservices architecture paradigm assists in Business Agility, where a large Monolith application is broken down into smaller functional units that can be developed & deployed faster. AWS cloud, on the other hand, provides services like Lambda, Elastic Container Services, Elastic Kubernetes Service that assists in developing & deploying microservices & deployment tools (CI/CD) like CodeBuild, CodePipeline for automating the deployment process. Combined, they provide an environment supporting an Agile Business.
Option A is incorrect. Elasticity is the ability to scale resources on-demand whenever there is an increase in load on the existing infrastructure. This Value proposition will benefit in substantial cost savings where I need not have to guess my capacity upfront.
Option B is incorrect. Flexibility is the ability to utilize a broad range of products depending on the application & infrastructure demands. For example, there are a broad range of EC2 instance pricing models ranging from On-Demand instances to Reserved Instances to Spot Instances and EC2 instance types like General Purpose, Compute Optimized, Memory Optimized. This will help with Low or No cost entries into the AWS cloud.
Option C is CORRECT. Using an Agile environment provided byAWS Cloud, I can release application features much faster than a traditional On-Premise environment.
Option D is incorrect. Operational resiliency results in the improvement of defined SLA’s and reducing unplanned outages that would result in downtime. The features of High Availability, Fault Tolerance gives rise to a resilient system.
