SAA-C03 · GUIDED PATH

Architecture, in dependency order.

Start with boundaries, build the packet path, then reason about resilience, performance, and cost.

01Architecture foundations0 / 2 complete · 70 minView lessons
1. 01Who is responsible—and what can fail?Learn who secures what in AWS, then use Regions and Availability Zones to describe which failures an architecture can survive.32 min
2. 02Scale the work without losing the stateLearn what must survive when a server disappears, then scale each tier without pushing more work than the next tier can handle.38 min
02Identity and account authorization0 / 3 complete · 120 minView lessons
03Progressive VPC and connectivityProgressive networking lab0 / 2 complete · 98 minView lessons
1. 06Trace a request through a VPCFollow one HTTPS request through subnet routes, security groups, network ACLs, a load balancer, and the return path.50 min
2. 07Choose the right private connectionClassify the destination, then choose an endpoint, PrivateLink, NAT, VPN, or Direct Connect without confusing privacy, encryption, and resilience.48 min
04Application and data security0 / 5 complete · 216 minView lessons
05Storage architecture0 / 2 complete · 96 minView lessons
1. 13Match each workload to the right AWS serviceStart from the interface and data behavior a workload requires, then eliminate services that cannot preserve those semantics before comparing operations or price.48 min
2. 14Choose storage by access pattern and performanceChoose object, file, block, scratch, or hybrid storage from the required access interface first, then test IOPS, throughput, latency, durability, and transfer time.48 min

1. 30Interactive scalable VPC topology and load balancingGrow a multi-tier VPC by planning nonoverlapping address capacity, AZ subnet tiers, route ownership, target capacity, and the correct Layer 7, Layer 4, or appliance load-balancing strategy.35 min
2. 31Interactive edge, global, private, and hybrid placementPlace global clients, Regional endpoints, private services, and on-premises networks by protocol, cacheability, static entry, latency, bandwidth, encryption, network scope, lead time, and failure requirements.35 min
