A large retail advertiser is launching a 48-hour global promotion and expects a sudden 8-10x spike in event traffic through the Meta Pixel and Conversions API integration, plus heavy internal usage of a Meta Ads Manager performance dashboard used by 600 campaign operators. You are the Solutions Architect supporting the client account, working with a 12-person cross-functional team across Solutions Engineering, Ads infrastructure, SRE, partner engineering, and client technical teams. The launch date is fixed in 6 weeks because media commitments are already booked.
The advertiser's CTO wants zero data loss and stable API performance during the promotion. The VP of Marketing wants all campaigns to launch on time and is pushing for full global rollout rather than a phased ramp. Meta's Ads Engineering lead wants to avoid risky last-minute architecture changes, while the SRE lead is focused on protecting shared capacity and preventing spillover impact to other advertisers.
You have a $180K incremental budget for load testing support, temporary capacity reservation, and partner engineering work. No new full-time headcount can be added. The team has 6 weeks total, with only 2 weeks available for production hardening after integration changes are complete. The client depends on one external tag management vendor and one internal data platform team that can each commit only 50% of a lead engineer's time. Current baseline traffic is 35K events/second at peak; projected promo peak is 300K events/second for 4 hours, with 99.9% event delivery expected.
