EC2, Lambda, EKS, S3 and resilient AWS architectures.
What are the recommended practices for validating backup and restore processes in AWS environments, and how can they be integrated into a Well‑Architected review?
How can I apply the AWS Well-Architected Framework’s performance‑efficiency pillar to systematically measure, diagnose, and remediate performance issues in an Amazon EC2‑based application? I am looking for a step‑by‑step explanation that covers baseline establishment, metric selection (such as CPU utilization, network throughput, and latency), data collectio
The goal is to ensure that agents using Amazon Connect’s Contact Control Panel (CCP) with screen readers can interact with both the default controls and any custom UI elements added through the SDK. The default CCP implements ARIA attributes for core call controls and status indicators, and offers keyboard navigation and high‑contrast mode. However, the SDK
When multiple objects are uploaded to a bucket in rapid succession, the application expects the corresponding Lambda functions to process events in the same order as the uploads. The goal is to determine whether S3 event notifications preserve a global order across all object keys, or if ordering is only guaranteed per key, and how Lambda concurrency limits
The same intended role can read an object from an approved diagnostic session, while a service running through an S3 VPC endpoint receives 403. The team has checked the role and bucket policy but has not reviewed the endpoint policy. How should the differing request paths be compared?
Goal Determine how AWS Lambda behaves when a function’s reserved concurrency setting exceeds the account‑level concurrency limit. Constraints Default account limit is 1,000 concurrent executions (can be increased via support). Maximum reserved concurrency per function is 1,000. Reserved concurrency is persistent across deployments and does not trigger automa
In the context of securing AWS resources with least privilege, what specific steps should I take to configure IAM roles for EC2 instances and bucket policies for S3 so that permissions are tightly scoped, how can I leverage IAM Access Analyzer to generate and validate these policies based on actual access activity, and what verification and rollback procedur
