LOCKEDIN / FORWARD-DEPLOYED ENGINEERING 101
Understand it.
Then build it.
You can be an experienced engineer and still be new to agents. Start with what each thing is and how it helps a person do useful work. Explore 48 original introductions across software, agents, cloud, security and delivery. Start here without a model key; each topic connects to deeper instruction and practice.

Networking fundamentals
How does a request reach a private service?
Networking connects software across machines. DNS resolves a name to an address, routing determines a reachable path, ports identify service endpoints, and TLS protects a connection. A private endpoint restricts reachability; it does not replace the service's identity and access checks.
Many enterprise AI demonstrations fail when moved behind private networks, proxies or restricted outbound access.
CONNECT IT TO WHAT YOU KNOW
Start with something familiar.
A function call stays inside your process. A network call crosses several boundaries, and each can fail independently before your function ever runs.
Reachable, encrypted and authorized are three different properties. A working connection proves none of the other two automatically.
Words worth knowing
- DNS
- Domain Name System: resolves names to network records.
- TLS
- Transport Layer Security: protects a connection and authenticates its peer.
- Egress
- Traffic leaving an environment.
ONE EXAMPLE / FICTIONAL CASE
Watch the work take shape.
The assistant works on a laptop but cannot reach the private procedure service from its deployed worker.
- 01Resolve and route
- 02Establish trust
- 03Authorize the operation
Resolve and route
Check the service name, address and allowed network path from the worker's environment.
A reachable destinationFROM RECOGNITION TO REASONING
Draw the path from UI to worker to model and data service.
- 01
Label public and private network boundaries.
- 02
Mark credentials, TLS and outbound destinations.
- 03
Assign DNS failure, TLS failure and permission denial to the correct layer.
A network sketch with three distinct failure diagnoses.
Compare your reasoning when you are ready
A DNS failure happens before an application response. A permission denial means a service was reached but the operation was not allowed. Changing prompts cannot repair either boundary.
Keep notes in your own working copy. Moving through these cards does not record completion.
TURN THE IDEA INTO USEFUL WORK
You can now go deeper.
Reachable, encrypted and authorized are three different properties. A working connection proves none of the other two automatically.
