Book
Cloud Platform Engineering
Seven chapters comparing the three major clouds where they genuinely differ: the compute spectrum and the ceilings that decide it, managed Kubernetes and the address exhaustion nobody plans for, identity models that do not transfer, networking and the internal traffic that outcosts your egress, storage and database traps, committed-use and spot mechanics, and an honest read on frameworks, market share and certifications.
Written for platform, SRE and solutions-architect candidates. Provider names are used sparingly on purpose — the structural differences outlast the branding, and every price should be re-checked before you quote it.
CHAPTER 1
The compute spectrum, and the ceilings that decide it
Virtual machines to functions, with the limits that actually make the choice — and the one architectural difference that matters more than cost.
CHAPTER 2
Managed Kubernetes, compared honestly
What the control plane actually costs, why your nodes run out of addresses before they run out of CPU, and who forces an upgrade on you.
CHAPTER 3
Identity across the three clouds
One cloud intersects permissions, two add them up — and the escalation path in each that turns a small compromise into a total one.
CHAPTER 4
Cloud networking, and where the money actually goes
Three VPC models that break each other's assumptions, and the internal traffic that costs more than your internet egress.
CHAPTER 5
Edge, DNS and delivery — what these services are before what they are called
Authoritative DNS, CDNs, anycast and the firewall layer: what each one actually does, then what each provider calls it, then where the mapping is a lie.
CHAPTER 6
Storage and databases: choosing, and the traps
The four charges that make a cheap storage tier expensive, and the database selection criteria that actually decide it.
CHAPTER 7
Commitments, spot, and what actually reduces a bill
The flexibility premium, the interruption notice you probably assume you have, and the eight interventions ranked by what they actually return.
CHAPTER 8
Frameworks, the market, and what is actually in demand
Which parts of the well-architected reviews are worth your time, what the share numbers really measure, and the honest read on certifications.
CHAPTER 9
How a service actually gets adopted in an enterprise
Services are not just switched on. They are blocked by default and walked through a sequence of gates — and knowing that sequence is what a platform interview is really asking about.
