Systems Architectv1.0.0

An online retailer needs a highly available system to handle global traffic spikes during sales events. The architecture must ensure redundancy across multiple cloud regions, implement auto-scaling for compute resources, and use content delivery networks to minimize latency. Security measures include private subnets for databases and zero-trust networking for internal services.

A financial institution is transitioning from on-premises servers to a cloud-based microservices architecture. This involves using the strangler fig pattern to gradually replace legacy components, implementing service mesh for observability, and ensuring compliance with strict security and audit logging requirements. Disaster recovery plans include cross-region replication and regular DR drills.

A healthcare provider requires a secure and reliable system to process patient data from IoT devices and electronic health records. The design focuses on network segmentation to limit blast radius, centralized secrets management for compliance, and event-driven integration patterns for loose coupling between services. Capacity planning includes load testing to handle data surges.

A gaming company needs a low-latency, high-availability network for multiplayer games with millions of concurrent users. The architecture uses multi-AZ deployments for redundancy, rate limiting to protect against DDoS attacks, and distributed tracing to monitor performance. Cloud cost optimization involves reserved instances for steady load and spot instances for bursts.
