CASE STUDY: RetailMart Overview: Industry: Retail/E-commerce Size: 2000 employees, $500M revenue Environment: - Monolithic Java app on VMware - Oracle RAC DB - F5 Load Balancers - 10 Gbps Direct Connect to AWS Requirements: - CapEx to OpEx - Handle 10x Black Friday traffic - Personalized recommendations - Modernize without impacting sales Exec Statements: - CEO: Omnichannel experience. - CFO: Predictable costs, no hardware refresh. - CTO: Break monolith, but Oracle DB stays on-prem for 2 years. Tech Reqs: - Zero downtime deployments - PCI-DSS compliance - Image processing pipeline - Async order processing Constraints: - Hybrid architecture required - Team knows Spring Boot, zero Kubernetes exp - 6-month timeline QUESTION: Which architectural pattern should you recommend to safely break down the monolithic application without impacting current sales?
CASE STUDY: HealthSecure Company Overview: HealthSecure provides electronic health record (EHR) systems and telemedicine platforms to hospitals across North America. They handle highly sensitive patient data. Current Technical Environment: - Co-located data centers with strict physical security. - Monolithic .NET applications running on Windows Server. - Microsoft SQL Server databases. - Custom-built video streaming solution for telemedicine. Business Requirements: - Migrate to the cloud to improve scalability during telemedicine surges. - Maintain strict compliance with HIPAA and HITECH regulations. - Enable interoperability with other healthcare providers using FHIR standards. Executive Statements: - CEO: "Telemedicine is exploding. We need to scale instantly to meet patient demand." - Chief Risk Officer (CRO): "Security and compliance are our license to operate. A data breach would destroy us." - CTO: "We want to leverage cloud-native AI/ML for medical image analysis in the future." Technical Requirements: - End-to-end encryption for all data at rest and in transit. - Strict network isolation to prevent data exfiltration. - Comprehensive audit logging of all data access. - High availability across multiple regions. Constraints: - Must use Customer-Managed Encryption Keys (CMEK). - Third-party auditors require detailed compliance reports. - Legacy .NET applications cannot be easily containerized without refactoring. QUESTION: To enable interoperability with other healthcare providers using FHIR standards and prepare for future AI/ML image analysis, which GCP service should you recommend?
A financial services company is evaluating a migration to Google Cloud. The CFO wants to understand the Total Cost of Ownership (TCO) and the expected Return on Investment (ROI) compared to their current on-premises data center. Which approach should you take to provide the most accurate financial assessment?
You are designing a highly available web application on Compute Engine. The application must automatically scale out during traffic spikes and scale in during quiet periods to save costs. If a VM crashes, it must be automatically recreated. Which GCP feature should you use?
