AI Gateway
A shared proxy in front of model providers that centralises routing, keys, quotas, caching, logging and safety policy.
API Gateway
A single entry point in front of a set of services that handles authentication, rate limiting, routing and protocol translation.
Anycast
Advertising the same IP address from many locations, so the network routes each client to the topologically nearest one.
Canary Release
Routing a small fraction of traffic to a new version, watching its metrics, and expanding or rolling back based on what they show.
Layer 4 vs Layer 7 Load Balancing
Balancing on connection metadata (IP and port) versus on the content of the request (path, host, headers).
Service Mesh
An infrastructure layer of sidecar proxies that handles service-to-service networking — mTLS, retries, timeouts, routing, telemetry — outside the application.
Strangler Facade
The routing layer in front of a legacy system that decides, per capability, whether a request goes to the old implementation or the new one.
Strangler Fig
Replacing a legacy system incrementally by routing individual capabilities to new implementations behind a facade, until nothing routes to the old system.
Subnet
A subdivision of a network's address range, used as the unit of routing and, in cloud, of availability-zone placement.
Zoom's Pandemic Scale-Up
Zoom grew from around 10 million to over 300 million daily meeting participants in roughly three months, absorbed by a hybrid architecture and a distributed media routing design.
In the October 2021 Meta outage, engineers reportedly struggled to physically access equipment because the access-control systems were also down. What class of dependency is that, and how do you find yours?
The case, as publicly reported On 4 October 2021, a command issued during routine backbone capacity assessment took down all connections between Meta's data cen
Users report seeing stale data intermittently. Replication lag is normally under a second but spikes to minutes twice a day. How do you handle it?
First: find the cause of the spikes Twice a day is a schedule, so look for one. The usual candidates, each with a different fix: A batch job or bulk write on th
Routing & BGP
How traffic finds you, anycast, and route withdrawal as a failure mode.
AI Cost Management
Token accounting, routing, caching and the context-window budget.
AI Gateways
Centralised routing, keys, quotas, caching, logging and safety policy.
API Gateway
A single entry point for policy, routing and protocol translation.
Reverse Proxies
One place for TLS, routing, caching, compression and rate limiting.

Routing capabilities to new implementations behind a facade, one at a time.
