🆕 INTERACTIVE FORMAT
🎯 PULSE CHECKS - Real pauses to test yourself
⚠️ TRAP SPOTLIGHTS - Exam traps highlighted live
💡 MEMORY HOOKS - Vivid analogies that stick
🔒 SITE-TO-SITE VPN
• Encrypted tunnel over the public internet
• Virtual Private Gateway (VGW) on AWS side
• Customer Gateway (CGW) on your side
• Quick, cheap, ~1.25 Gbps per connection
• Subject to internet conditions
Hook: Encrypted tunnel through public roads.
🛣️ DIRECT CONNECT (DX)
• Dedicated, PRIVATE, physical connection
• Consistent performance, predictable latency
• 1 to 100 Gbps bandwidth
• NOT encrypted by default (run VPN over it!)
• Takes weeks to provision
• Resilience: dual connections OR VPN backup
Hook: Your own private highway to AWS.
🚉 TRANSIT GATEWAY
• Hub-and-spoke for thousands of VPCs
• Transitive routing (solves VPC peering limits)
• Share across accounts via RAM
• Only AWS service supporting IP multicast
• ECMP combines VPNs for more bandwidth
Hook: Central train station - one hub, everything reachable.
🌉 STORAGE GATEWAY (3 types!)
• FILE GATEWAY: NFS/SMB file access, backed by S3
• VOLUME GATEWAY: iSCSI block storage (Cached = primary in cloud, Stored = primary on-prem)
• TAPE GATEWAY: replaces physical tapes, virtual library → S3/Glacier
Hook: Bridge with 3 lanes - files, blocks, tapes.
📡 DATASYNC
• ONLINE scheduled data transfer
• NFS, SMB, HDFS, S3 API
• Preserves permissions & metadata
• Up to 10 Gbps per agent
• On-prem to AWS, or AWS to AWS
❄️ SNOW FAMILY (offline transfer!)
• Snowball Edge: up to petabytes + edge computing
• Snowmobile: up to 100 PB (exabyte scale)
• THE RULE: network transfer >1 week → Snowball
• Runs EC2/Lambda on-device for disconnected sites
• Import to S3 FIRST, then lifecycle to Glacier
Hook: DataSync = internet courier. Snowball = truck of drives.
🗄️ DMS (Database Migration Service)
• Source stays OPERATIONAL during migration
• Full load + CDC (Change Data Capture)
• Homogeneous (same engine) or heterogeneous
• Heterogeneous needs Schema Conversion Tool (SCT)
• Multi-AZ for redundancy
🏢 AWS OUTPOSTS
• AWS-managed racks IN your data center
• Same AWS services/APIs/tools on-premise
• Low latency, data residency, local processing
• Runs EC2, EBS, S3, EKS, ECS, RDS, EMR
Hook: Outposts = AWS branch office in your building.
⚠️ TOP EXAM TRAPS
1. VPN (encrypted/quick/cheap) vs DX (dedicated/private/consistent)
2. Need it fast? VPN now, Direct Connect later
3. DX single connection isn't HA - use dual or VPN backup
4. Network transfer >1 week = Snowball
5. Snowball can't import to Glacier directly (S3 first)
6. Storage Gateway by protocol: NFS/SMB=File, iSCSI=Volume, tapes=Tape
7. DataSync = online scheduled; Snowball = offline physical
8. Heterogeneous DB migration needs SCT
9. Transit Gateway = transitive routing + IP multicast
10. Outposts = AWS hardware in YOUR data center
📊 DECISION FRAMEWORK
• Quick encrypted link? → VPN
• Dedicated consistent performance? → Direct Connect
• Many VPCs connected? → Transit Gateway
• Expose cloud storage on-prem? → Storage Gateway
• Online scheduled transfer? → DataSync
• Huge one-time transfer? → Snowball
• Minimal-downtime DB migration? → DMS
• AWS services on-premise? → Outposts
