Mastering Alibaba Cloud Compute Services: ECS and Serverless
Compute services are central to any cloud offering, and Alibaba Cloud's Elastic Compute Service (ECS) is its flagship IaaS product.
You should be familiar with ECS instance types, purchasing options (pay-as-you-go, subscription), and key features like auto-scaling and snapshots.
Function Compute, Alibaba Cloud's serverless offering, is also increasingly important for modern, event-driven architectures.
Example Question: "Describe a scenario where you would choose Function Compute over ECS for an application."
Answer Focus: Emphasize event-driven tasks, sporadic workloads, automatic scaling, and reduced operational overhead for Function Compute.
For ECS, highlight persistent servers, long-running processes, and greater control over the operating system.
