An online news portal is preparing for an event that will cause unpredictable increases in viewer traffic. Which service should be utilized to ensure that compute capacity can scale without manual intervention to meet the fluctuating demand?
Managing scalability manually through container orchestration with fluctuating load adjustments
Using a serverless compute platform that automatically scales and manages the compute fleet
Allocating fixed clusters of compute instances in anticipation of highest expected load
Running containerized applications on a serverless engine with manual scaling policies
The best choice for unpredictable and variable traffic with spikes is a compute service that scales automatically without requiring manual intervention for provisioning or managing servers. This is where serverless computing shines, as it abstracts the servers away and automatically adjusts to the traffic. Lambda fits the bill as it automatically manages the underlying compute resources. While EC2 instances can scale, this process is not as immediate or seamless as with Lambda. Fargate provides a serverless container experience, but it still requires some configuration for scaling and does not scale as responsively as Lambda for sudden spikes. ECS on EC2 instances also provides scalability but requires more hands-on management compared to the automatic scaling provided by Lambda.
