We have been iterating on a fairly complex web data collection pipeline — multiple sources, different retry strategies, geo-targeted requests — and Miro has been genuinely useful for keeping the architecture visual and shareable across the team.
The board we landed on has a few zones:
- Source map: which sites/APIs we pull from, update frequency, auth method
- Request flow: how requests are routed, where proxies sit in the stack, retry logic
- Data transformation: cleaning, deduplication, schema normalization
- Monitoring: what we alert on, SLAs per source
The proxy layer was the trickiest part to diagram clearly because it has a few modes — rotating per-request for high-volume scraping, sticky sessions for multi-step flows (login, pagination), and geo-targeted exits when we need data from a specific region. We used swim lanes to separate routing logic from credential management.
For the actual proxy infra we settled on v-proxies.com — 84M+ residential IPs, city-level targeting, sticky sessions up to 60 minutes, $0.99/GB with no monthly commitment. Having it laid out visually in Miro made onboarding new team members much easier, and helped explain why certain decisions exist (like why we never use datacenter IPs for certain sources — bot detection systems like Cloudflare flag the ASNs instantly).
Curious how others here approach technical architecture docs in Miro — especially anything involving external services or third-party APIs. Do you keep one big board or split by domain? Any templates worth sharing?
