CASE STUDY: TechStream Gaming
Overview: 500 employees, $100M revenue. On-prem US/EU, 200 servers, 5TB MySQL. 2M peak users, $100K/mo cost.
Business: Reduce cost 40%, 5x growth, launch APAC/SA/Africa, daily deployments.
Executives:
- CEO: "Scale rapidly to compete. Cloud is critical."
- CFO: "Cost reduction paramount. Max $100K/mo. ROI in 18 months."
- CTO: "Team has limited cloud experience. 99.95% uptime non-negotiable."
Tech: <100ms latency globally, real-time analytics, 5x seasonal spikes, EU data residency, DDoS protection, CI/CD.
Constraints: 12-month migration, 4hr max downtime, 20 devs (Java/MySQL), 5 ops (limited cloud), $2M budget.
Which migration strategy should you recommend for the core gaming application to meet the business and technical requirements?

How should you design the network architecture to ensure DDoS protection and compliance with the EU data residency requirement?
Answer options:
Use a Network Load Balancer with Cloud Armor, and set up a separate VPC for EU users.
Use a Global External HTTP(S) Load Balancer with Cloud Armor for DDoS protection, and configure backend services to ensure EU users are only routed to EU clusters.
Use Cloud DNS routing with Internal Load Balancers and VPC Service Controls.
Deploy third-party virtual firewall appliances in each region and use Cloud NAT.
