Zorluk: ZorAWS Compute Services

An organization is evaluating hosting models for their application workloads on AWS. Match each operational requirement to the most appropriate AWS compute service.

  • Deploying containerized microservices where the customer defines CPU and memory requirements, but AWS manages server provisioning, operating system patching, and scaling.AWS Fargate
  • Running a legacy application that requires custom kernel modifications, direct administrative root access, and persistent state on the guest operating system.Amazon EC2
  • Launching a simple developer-friendly project that needs a bundled virtual private server (VPS) package with a predictable, flat-rate monthly pricing model.Amazon Lightsail
  • Executing short-lived, event-driven code that runs in response to database changes or file uploads, automatically scales down to zero, and incurs no idle capacity charges.AWS Lambda

Cevap

Matching AWS Fargate for serverless containers, Amazon EC2 for full guest OS control, Amazon Lightsail for simple pre-configured virtual private servers, and AWS Lambda for event-driven functions.
AWS Fargate matches the serverless container configuration requirement. Amazon EC2 matches the legacy custom-kernel/direct-access requirement. Amazon Lightsail matches the low-cost, flat-rate, pre-configured VPS requirement. AWS Lambda matches the serverless, event-driven scale-to-zero function execution requirement.

Adım Adım Çözüm

1
Analyze containerized application requirements that specify container-level resources but forbid managing host servers.
Identify AWS Fargate as the serverless compute engine for containers.
AWS Fargate abstracts server management, allowing users to define container specifications while AWS handles the scaling and patching of the underlying instances.
2
Examine requirements for administrative access, custom kernel configuration, and direct OS control.
Identify Amazon EC2 as the correct service.
Amazon EC2 provides virtual machines with full administrative control, allowing users to choose the OS and modify the kernel.
3
Determine which service provides pre-configured VPS resources under a simple, flat pricing tier.
Identify Amazon Lightsail.
Amazon Lightsail bundles compute, storage, and networking features into a single, predictable monthly fee, making it ideal for simple applications.
4
Identify the event-driven compute model that scales to zero and has zero idle charges.
Identify AWS Lambda.
AWS Lambda executes code only when triggered by events, dynamically scaling based on incoming requests and charging only for active runtime.
