Application Portfolio Management
Maintaining an inventory of every application with its owner, cost, business value and technical health, and using it to decide what to invest in, replace or retire.
Layered Architecture
Organising code into horizontal layers — presentation, application, domain, data — where each layer may only call the one beneath it.
Change Data Capture
Publishing a stream of a database's row-level changes by reading its replication log, without modifying the application that owns it.
Microservices
An architectural style where an application is a set of independently deployable services, each owning its data and aligned to a business capability.
OAuth 2.0
An authorisation framework that lets an application obtain scoped, delegated access to a resource without handling the user's credentials.
OWASP Top Ten
A periodically updated consensus list of the most critical web application security risks, useful as a design-review checklist.
Service Mesh
An infrastructure layer of sidecar proxies that handles service-to-service networking — mTLS, retries, timeouts, routing, telemetry — outside the application.
Shopify's Pods and Modular Monolith
Shopify handles Black Friday scale with isolated pods — complete stacks each serving a subset of merchants — while keeping the application itself a deliberately modular monolith.
Sidecar
Deploying a helper process alongside the main application in the same unit, to supply cross-cutting behaviour without changing the application.
TOGAF
An enterprise architecture framework whose central element is the ADM, an iterative cycle from vision through business, data, application and technology architecture to implementa…
Tool Calling
Giving a model a set of typed function definitions it can request to invoke, with the application executing the call and returning the result.
Application Discovery
Establishing what applications exist, what they depend on, who owns them and whether anyone uses them — the step whose absence makes every later step a guess.
Application Performance Monitoring
Instrumentation inside the application that attributes latency and errors to specific code paths, queries and dependencies.
Architecture Cost Model
A calculation, made during design, of what an architecture will cost to run at expected and at peak volume.
Architecture Decision Log
The ordered, immutable collection of a system's decision records, read as a history rather than as a specification.
Architecture Decision Record
A short, immutable document capturing one architectural decision, its context, the alternatives, and its consequences.
Architecture Principle
A durable, agreed rule that constrains design decisions in advance, stated with its rationale and its implications.
Architecture Review Board
A forum that reviews significant designs against standards, risks and strategy before commitment.
Architecture Style
A named, coarse-grained way of organising a whole system, as distinct from a pattern that solves one recurring problem inside it.
Architecture Trade-off Analysis Method
A structured evaluation that scores an architecture against prioritised quality-attribute scenarios and identifies the points where those attributes conflict.
Cell-Based Architecture
Partitioning a service into complete, independent copies of itself, each serving a subset of customers, so a failure is bounded to one cell.
Clean Architecture
Concentric layers with a strict dependency rule — source code dependencies point only inwards, towards higher-level policy.
Application Architecture
The application estate as a designed portfolio rather than an accumulation.
LLM Application Architecture
The shape of a production system with a model in the request path.
Application Portfolio Management
Inventory, ownership, cost and health for every application.
Application Rationalisation
Retire, consolidate, replatform — and why retirement is under-applied.
Cloud Migration
Per-application disposition, sequencing and the capability change underneath.
EA Domains
Business, application, data and technology architecture as viewpoints.
Encryption
At rest, in transit, and at the application layer — three different threats.
AI-Era Architecture
General material on architecting systems that include models.
Application Decomposition
Finding seams in a monolith, starting from the data.
Application Performance Monitoring
Attributing latency to code paths, queries and dependencies.
Architecture Communication
General material on communicating architecture.
Architecture Cost Modelling
Pricing a design before building it, at expected and at ten times volume.
Architecture Decision Records
One decision, its context, alternatives and consequences, kept immutable.
Architecture Decision-Making
General material on making and recording architectural decisions.
Architecture Diagrams
Choosing an audience and refusing to mix levels of abstraction.
Architecture Documentation
What to write down, at what altitude, and what nobody will ever read.
Architecture Fundamentals
General material on what solution architecture is and what an architect is accountable for.
Architecture Governance
Preventive, automated controls rather than review meetings.
Architecture Patterns
General material on architectural patterns and their trade-offs.
Architecture Principles
Durable agreed rules that rule options out, stated with rationale and implications.
Architecture Review Boards
Thresholds, early engagement and a real route to accept deviation.
Architecture Reviews
Reviewing early enough to influence rather than to veto.
Architecture Roadmaps
Sequencing change across an estate with dependencies and funding.
Architecture Roles
Solution, enterprise, domain and platform architecture, and where each is accountable.
Architecture Styles
System-level organising shapes, and how they differ from problem-level patterns.
Business Architecture
General material on the business side of architecture.
Cell-Based Architecture
Complete isolated copies each serving a subset of customers.
Clean Architecture
Concentric layers with dependencies pointing only inwards.
Cloud Architecture
General material on designing for cloud platforms.
AI-Era Architecture
AI workloads meeting security, data, networking, reliability and cost.
API & Integration Architecture
Contracts between systems, and the compatibility discipline that keeps them working.
Architecture Communication
Explain the same architecture to a CEO, an engineering manager and an engineer.
Architecture Decision-Making
Where senior engineer becomes architect: evaluate, choose, write it down.
Architecture Fundamentals
What architecture actually is: drivers, constraints, trade-offs and the principles behind them.
Architecture Patterns
Patterns as tools for recurring problems, with forces and consequences.
Business Architecture
Connecting technology decisions to the outcomes that fund them.
Cloud Architecture
Cloud as a set of architectural capabilities, not a catalogue of service names.
Cost Architecture & FinOps
Architecture is also economics; exceptional architects can price their designs.
