🎁 Free SAA-C03 cheat sheet for this series - link at the bottom.Topic challenge #5, segmented format! Quick revision, then 13 compute questions split into 3 themed blocks - so it flows like a guided session, not a question dump.🆕 THE FORMAT🧠 Tight intro (no long front-loaded lecture)📦 3 themed blocks with teaching beats between them: 1️⃣ EC2 Fundamentals (instances & placement) 2️⃣ Scaling & Cost (Auto Scaling & purchasing) 3️⃣ Serverless & Containers (Lambda, ECS/EKS/Fargate)⏱️ A pause after each question to lock in YOUR answer✅ The answer + WHY it's right❌ WHY each wrong option is wrongBecause on the real exam, eliminating the plausible-but-wrong options is the whole game.🎯 THE PAYOFFBy the end you'll have the 4 compute decisions the exam leans on most locked in - the ones that quietly decide a handful of marks on test day.📋 THE 13 QUESTIONS TESTBLOCK 1 - EC2 Fundamentals:• Cluster placement group (lowest-latency HPC)• Memory-optimized instances (in-memory cache)• On-Demand Capacity Reservations (guaranteed AZ capacity)• Accelerated computing (GPU for ML)BLOCK 2 - Scaling & Cost:• Scheduled scaling (predictable daily peak)• Reserved/Savings Plans (steady 3-year workload)• Spot Instances (interruptible batch)• Target tracking scaling (hold CPU at 50%)• Mixed instances policy (blend On-Demand + Spot)BLOCK 3 - Serverless & Containers:• Fargate (containers, no instance management)• Lambda (event-driven function)• EKS (when you specifically need Kubernetes)• ECR (Docker image registry)💡 THE 4 COMPUTE DECISIONS DRILLED1. Instance family: match the bottleneck (memory/compute/GPU)2. Purchasing: On-Demand / Reserved / Spot / Capacity Reservation3. Scaling: scheduled (clock) vs target tracking (metric) vs mixed4. Compute model: Lambda / Fargate / ECS / EKS / ECRSpot which group the question is testing, and the answer falls out.🎓 SCORINGGot 9+ right (~70%)? Your compute knowledge is in good shape. Missed some? Compute runs through a huge share of the exam - now you know where to focus.🗣️ The segmented format is helping people stay to the end - did the blocks work for you?
