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.
Architecture Decision Log
The ordered, immutable collection of a system's decision records, read as a history rather than as a specification.
Consent Management
Capturing, storing, honouring and evidencing a data subject's permissions for specific processing purposes, including withdrawal.
Global Traffic Management
The layer that decides which region a given user reaches, using DNS, anycast or an edge network, and that performs regional failover.
Identity and Access Management
The system of record for principals, credentials and permissions, and the policy engine that decides what each principal may do.
Log Compaction
A retention policy that keeps only the most recent value for each key rather than deleting by age, so the log becomes a durable snapshot of current state.
Log-Based CDC
Capturing changes by reading the database's own write-ahead log, which sees every change with no load on the source and no application involvement.
Offset Management
How a consumer records its position in a stream, and the decision that determines whether processing is at-least-once or at-most-once.
Secrets Management
Storing, distributing, rotating and auditing credentials so that they never live in code, images or configuration files.
Tamper-Evident Log
An audit log constructed so that any modification or deletion of past entries is detectable, typically by chaining entries cryptographically.
Write-Ahead Log
Recording every change to a durable sequential log before applying it, so that a crash can be recovered by replaying the log.
Blameless Postmortem
An incident review that seeks the systemic conditions that made a failure possible, explicitly excluding individual fault.
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.
Correlation ID
A single identifier attached to one logical operation and included in every log line it produces, anywhere in the system.
Dynamic Secrets
Credentials generated on demand for a specific consumer with a short lease, rather than stored, shared and rotated periodically.
Envelope Encryption
Encrypting data with a locally-generated data key, then encrypting that key with a master key held in a key management service, and storing the wrapped key alongside the ciphertext.
Event Store
An append-only store of domain events organised into per-entity streams, serving as the system of record rather than as a log beside it.
Event Stream
An append-only, retained log of events that many independent consumers read at their own position, and can re-read.
Hardware Security Module
A tamper-resistant device that generates and stores keys and performs cryptographic operations without the key material ever being extractable.
Incident Command
Assigning explicit roles during an incident — commander, operations lead, communications lead, scribe — so coordination does not compete with diagnosis.
Key Rotation
Periodically replacing a cryptographic key with a new one while retaining the old for decrypting existing data, so exposure from any single key is bounded.
LinkedIn and the Origin of Kafka
Kafka was built to replace point-to-point data integration between many systems with a single durable log that any system could publish to and any number could read.
Permission Boundary
A policy limiting the maximum permissions an identity can have, used so that the ability to create roles does not become the ability to grant unlimited privilege.
Prompt Registry
A versioned store of production prompts with their model bindings, parameters and evaluation results, so a prompt change is a reviewable, traceable, reversible deployment.
Raft
A consensus algorithm designed to be understandable, decomposing agreement into leader election, log replication and safety.
Replication Lag
How far behind a replica is, measured in time or in log position — the quantity that determines how stale a replica read can be.
Secret Zero
The credential a workload needs in order to authenticate to the secret manager — the one secret that cannot itself be stored in the secret manager.
Severity Levels
A predefined scale of incident impact that determines who is woken, how fast, and what process applies.
Structured Logging
Emitting log entries as machine-parseable key-value records rather than as formatted prose.
Workload Identity
Giving a running workload a cryptographically verifiable identity issued by the platform, so it obtains short-lived credentials without a stored secret.
An LLM feature that worked last week now gives worse answers. Nothing was deployed. How do you find out what changed, and what should have been in place?
What the interviewer is testing Whether you treat an AI feature as a system with configuration and dependencies, or as a black box that mysteriously drifts. Wha
An estate has database passwords in environment variables across 200 services. Design the migration to a secrets manager.
Sequence it by risk, not by convenience Phase 0 — stop the bleeding. Secret scanning in CI and on the existing repositories, blocking new commits containing cre
Equifax was breached in 2017 through a vulnerability with a patch available two months earlier. Beyond "patch faster", what architectural and governance failures does that imply?
The case, as publicly reported Apache Struts vulnerability CVE 2017 5638 was disclosed in March 2017 with a patch available. An internet facing dispute portal a
Log Management
Aggregation, retention tiering, search and the cost of keeping everything.
AI Cost Management
Token accounting, routing, caching and the context-window budget.
Application Portfolio Management
Inventory, ownership, cost and health for every application.
Identity & Access Management
Workload identity, roles, permission boundaries and usage-based review.
Incident Management
Command roles, severity levels and mitigation before diagnosis.
Key Management
Rotation, separation of duty, envelope encryption and crypto-shredding.
Prompt & Version Management
Prompts as reviewed, versioned, evaluated production configuration.
Secrets Management
Runtime injection, dynamic credentials and rotation applications survive.
Change Data Capture
Turning a database's replication log into a stream, and its coupling risk.
Correlation IDs
One identifier propagated through every hop and every log line.
Decision Practice
Thresholds, review, supersession and keeping the log alive.
Event Sourcing
Storing the change log as the system of record, and what that costs forever.
Event Sourcing
The event log as the system of record, with state as a projection.
Logging
What to log, at what level, and what must never appear in a log.
