Which hybrid connectivity solution should you implement to ensure high throughput and low latency?
CASE STUDY: TechStream Gaming Company Overview: TechStream Gaming is a global multiplayer game developer with 500 employees and $100M annual revenue. They recently launched a hit mobile game that is growing rapidly. Current Technical Environment: - On-premises data centers in US and EU. - 200 bare-metal servers running Linux. - Self-managed MySQL databases (5 TB total) for player profiles and inventory. - Peak concurrent users: 2 million. - Current monthly infrastructure cost: $150K. Business Requirements: - Reduce infrastructure costs by 40%. - Support 5x user growth over 2 years. - Launch in 3 new regions (APAC, SA, Africa). - Improve deployment speed from 1 week to daily. Executive Statements: - CEO: "We need to scale rapidly to compete. Cloud migration is critical." - CFO: "Cost reduction is paramount. We cannot exceed $100K/month. ROI must be achieved in 18 months." - CTO: "Our team has limited cloud experience. Reliability is non-negotiable - 99.95% uptime minimum." Technical Requirements: - Sub-100ms latency for players globally. - Real-time analytics on player behavior. - Seasonal traffic spikes (5x during holidays). - CI/CD pipeline for daily deployments. Constraints: - Migration must complete in 12 months. - Cannot exceed 4-hour downtime during cutover. - Dev team: 20 engineers (Java, MySQL). - Ops team: 5 engineers (limited cloud experience). QUESTION: How should you design the global network architecture to ensure sub-100ms latency for players across all regions while protecting against DDoS attacks?
CASE STUDY: ShopGlobal Company Overview: ShopGlobal is an international e-commerce retailer. They are preparing for their largest annual sales event (Black Friday) and want to migrate off their aging on-premises infrastructure. Current Technical Environment: - 3 on-premises data centers (US-East, US-West, EU-Central). - VMware vSphere environment with 500 VMs. - Monolithic Java application running on Tomcat. - Oracle RAC database for transactions. - 50 TB of product images on SAN storage. Business Requirements: - Ensure 100% availability during the upcoming holiday season. - Modernize the application architecture over the next 3 years. - Reduce capital expenditure (CapEx) by shifting to an OpEx model. Executive Statements: - CEO: "Downtime during Black Friday costs us $1M per hour. We need bulletproof reliability." - CFO: "We want to stop buying hardware. Move everything to a pay-as-you-go model." - CTO: "We want to eventually move to microservices, but we don't have time to rewrite the app before the holidays." Technical Requirements: - Migrate the existing VMs to the cloud with minimal changes initially. - Implement a global CDN for product images to reduce latency. - Set up disaster recovery with an RPO of 15 minutes and RTO of 1 hour. - Ensure PCI-DSS compliance for payment processing. Constraints: - The migration must be completed in 4 months (before the code freeze). - The Oracle database license cannot be easily transferred to the cloud. - The team has no experience with Kubernetes or containers yet. QUESTION: How should you architect the storage and delivery of the 50 TB of product images to meet the technical requirements?
An enterprise organization has 50 different departments, each requiring their own GCP project for billing and resource isolation. However, the central security team mandates that all network traffic must route through a central firewall appliance, and departments must not manage their own external IP addresses.
