Edge delivery for content platforms: fast everywhere, including Nairobi
Static-first rendering at the edge serves content-platform traffic from points close to users, survives origin outages and costs a fraction of always-on server fleets. The trade-offs are manageable and worth naming.

Content platforms live and die by time-to-first-content. Edge delivery - pre-rendering pages at build time and serving them from globally distributed points of presence - remains the strongest default for public content, and modern edge runtimes finally make the dynamic parts fit too.
Static-first, dynamic-where-needed
Articles, resources, FAQs and landing pages render to static HTML at deploy time. First paint needs no server round-trip; the HTML arrives complete and interactive within milliseconds on mid-range phones. Dynamic behaviour - search-as-you-type, recommendations, the AI assistant - runs as small client-side interactions calling typed JSON APIs at the edge.
This split mirrors the physics of the network: the heavy payload travels once per deploy; per-request computation stays small and local.
The trade-offs, named honestly
Static export complicates anything requiring per-request server context: cookies-driven rendering, geo-specific content, server-side secrets. The mitigations are standard - client-side hydration of personalised fragments, API-mediated dynamics, secrets confined to edge functions. None are exotic; all should appear in the architecture diagram from day one.
Cache invalidation is the other named tax. Content platforms change on editorial schedules, so immutable assets with hashed names plus instant full-site invalidation on deploy covers nearly every case without fine-grained purging logic.
Measured, not assumed
Whatever the delivery model, measure from representative networks. Lab metrics from fibre connections flatter any architecture. Field data from mid-range devices on mobile networks tells you whether the edge actually bought you what its diagram promised.
