Course 01
Deployment & Reliability
Understand deployment deeply enough to make the right architectural call - and to judge whether the agent you asked actually carried it out.
For someone who has shipped something live by prompting and does not read code. DORA's 2025 research is blunt about the problem: AI raises how much you ship and how often it breaks.

The Language of Systems
The five behaviours every production system exhibits, stated as maths before they are stated as advice.
What Deployment Is
Deployment stated as a mechanism rather than a button, and the four things production is judged on.
The Network
What the request crosses before it reaches you, and the one physical limit in the whole course.
The Machine
What your code actually runs on, from the process up to the container.
The Types, Compared
The real options for where code runs, and the duty cycle that decides between them.
State and Consistency
The layer that makes deployment hard, taught from the Cambridge distributed systems course.
Access and Blast Radius
Where every documented vibe-coding catastrophe actually landed.
Releasing
Getting a change in front of users without an outage, and measuring whether you did.
Detecting Failure
Knowing what production is doing, and deciding when that is bad.
How Systems Fail
Module one's mathematics cashing out as real outages: the utilisation curve you already met, retry storms, cascading and correlated failure, and shedding load on purpose.
Scale, Cost, and Limits
What more machines buy you, what they cost, and when to stop.
