Book
Infrastructure & Reliability
Reliability and error budgets, capacity arithmetic, networks, storage and the restore you have not tested, the physical layer, a debugging method that transfers, running production, and an honest look at Kubernetes.
For the Platform, IT Infrastructure and SRE archetypes — and for anyone whose interview will involve designing a system with numbers attached.
CHAPTER 1
What actually makes a system reliable
Not uptime. A shared, written definition of acceptable, and a budget for spending the rest.
CHAPTER 2
Capacity, and the cost of being wrong in each direction
Under-provision and you fail. Over-provision and you fund nothing else. The arithmetic is learnable in an afternoon.
CHAPTER 3
Networks, without the certification
The layer everything blames and almost nobody measures properly. Six mechanisms explain most of what you will meet.
CHAPTER 4
Storage, durability, and the restore you have not tested
A backup that has never been restored is a hypothesis. This chapter is about turning it into evidence.
CHAPTER 5
The physical layer, and why AI broke the datacentre
Power, cooling and space. Unfashionable, non-optional, and currently the binding constraint on the entire industry.
CHAPTER 6
Debugging that transfers
One method, applied to every resource. It turns troubleshooting from intuition into a checklist you can hand to someone else.
CHAPTER 7
Running production
Change, incidents and toil. The three things that consume an operations team, and what to do about each.
CHAPTER 8
Kubernetes, honestly
What it genuinely solves, what it costs, and the four things that break in production.
