Tomás Brenner
Distinguished Engineer, Networking
Tomás builds the routing layers that other teams take for granted. He is unreasonably fond of packet captures and believes most cloud outages are DNS until proven otherwise.

Packets Across Clouds
Networking for AWS and GCP Practitioners
Multi-cloudPractitionerNetworking
Cloud networking is where comfortable abstractions go to die. Two VPCs that 'should' be connected are not; DNS resolves differently inside and outside the mesh; a transit gateway silently drops what you expected it to forward.
Tomás Brenner covers the concrete mechanics on both AWS and GCP: routing tables and their evaluation order, peering versus transit topologies, private service connectivity, hybrid DNS resolution, and the diagnostic sequence that isolates a fault in minutes rather than hours.
Every chapter includes the packet-level evidence you should be collecting, not just the console screenshot.
What you'll learn
- Predict route evaluation order on both AWS and GCP
- Choose between peering, transit, and private service connect topologies
- Make hybrid DNS resolve consistently in both directions
- Run a repeatable diagnostic sequence for connectivity faults
