Cloud Pricing Models
The purchase options for cloud compute — on-demand, committed use, and spot — which differ by up to 90% for identical hardware.
Reference Architecture
A pre-approved, documented template for a recurring class of solution, so that similar problems do not get individually redesigned.
Burstable Instance
An instance that provides a low baseline CPU allocation and accrues credits while idle, spendable for short periods of full performance.
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.
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…
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.
Reference Models
Shared conceptual frames — layering, tiers, viewpoints — and their limits.
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 Models
Instances, containers and functions, and what each is priced and shaped for.
Consistency Models
Linearizable, sequential, causal, eventual, and the session guarantees between them.
Operating Models
How delivery, platform and governance functions fit together.
Reference Architectures
Pre-approved templates for recurring solution shapes.
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.
