A live One Direction event drives massive ten‑minute spikes so the team uses App Engine for VM autoscaling but avoids constant capacity costs by writing numeric metrics into dedicated memcache with sharded counters, tracking only top‑30 countries plus a rest‑of‑world bucket, and keeping a 32-entry hero list for winners. The design sacrifices full raw records for fast increments, preserves privacy, handles tall skinny spikes, and yields a cloud bill smaller than the post‑event drinks.
