Cloud Pricing Models
The purchase options for cloud compute — on-demand, committed use, and spot — which differ by up to 90% for identical hardware.
Burstable Instance
An instance that provides a low baseline CPU allocation and accrues credits while idle, spendable for short periods of full performance.
Instance Family
A group of instance types sharing a resource profile — general purpose, compute optimised, memory optimised, storage optimised, accelerated — chosen by which resource the workload…
Causal Consistency
A model guaranteeing that operations which causally depend on one another are seen in the same order everywhere, while concurrent operations may be seen in any order.
Consistent Prefix Read
A guarantee that if a sequence of writes happens in a given order, a reader sees a prefix of that sequence — never an out-of-order subset.
ETL vs ELT
Whether data is transformed before loading into the target or after it, which decides where the compute happens and how much raw history you keep.
Linearizability
The strongest single-object guarantee — every operation appears to take effect instantaneously at some point between its call and its return.
Read-Your-Writes Consistency
A session guarantee that a client always sees its own updates, even when reads are served from replicas that may lag.
Serverless
A model where the provider allocates and scales compute per request, and you are billed for execution rather than for provisioned capacity.
A fleet of 200 instances averages 15% CPU and 85% memory. Finance wants a 40% cost reduction. What do you do?
The diagnosis The instance family is wrong. 15% CPU and 85% memory means the workload is memory bound running on general purpose or compute optimised instances,
Your observability bill is now 40% of your compute bill. Leadership wants it cut in half without going blind. What do you cut?
What the interviewer is testing Whether you understand what each telemetry type is for , so you can cut the redundant parts rather than cutting uniformly — whic
Compute Models
Instances, containers and functions, and what each is priced and shaped for.
Cloud Pricing Models
On-demand, committed and spot, and the crossover arithmetic.
Communicating Threat Models
Making risk legible to people who will fund or accept it.
Compute Optimisation
Instance families, utilisation, and architecture that wastes less.
Consistency Models
Linearizable, sequential, causal, eventual, and the session guarantees between them.
Operating Models
How delivery, platform and governance functions fit together.
Reference Models
Shared conceptual frames — layering, tiers, viewpoints — and their limits.
AI-Era Architecture
General material on architecting systems that include models.
CQRS
Separating the write model from the read models that serve queries.
CQRS
Separate models for writing and reading, each optimised for its job.
Edge Computing
Moving compute towards the user, and what cannot follow it.
Telemetry Cost
Observability bills that rival compute, and where to cut without going blind.
