A media broadcasting company deploys a video transcoding application on Azure to process user-uploaded content. The application experiences unpredictable spikes in uploads when breaking news events occur. The company configures the application to automatically add or remove virtual machines as demand fluctuates. Additionally, they deploy the application across multiple Availability Zones to ensure it remains operational if a single datacenter fails.
Which of the following cloud concepts are represented in this architecture? (Select TWO)
- Elasticity, demonstrated by the automatic addition and removal of virtual machines in response to unpredictable traffic spikes.Answer
- High Availability, demonstrated by deploying the application across multiple Availability Zones to ensure continuous operation during a single datacenter outage.Answer
- CDisaster Recovery, demonstrated by the capability of the local application to withstand a single datacenter failure without losing service access.
- DVertical Scaling, demonstrated by automatically adjusting the CPU and RAM capacity of existing virtual machines to handle demand.
- ERegional Redundancy, demonstrated by utilizing Availability Zones that span multiple separate geographical regions to achieve fault tolerance.
Answer
The architecture represents Elasticity, through the automatic horizontal scaling of virtual machines to meet unpredictable demand, and High Availability, by utilizing multiple Availability Zones within a region to ensure resilience against a datacenter failure.
The correct concepts are elasticity and high availability. Elasticity is shown when the application automatically adjusts its compute resources (adding/removing VMs) to match unpredictable load fluctuations. High Availability is shown when the system is deployed across multiple Availability Zones to survive the failure of a single datacenter within the region.
