What this post added

This post details Vercel's Frontend Cloud capabilities for ensuring the resiliency of global web applications. It elaborates on automatic scaling to handle traffic spikes (e.g., Black Friday, swag drops) by leveraging serverless architecture and the Edge Network with its global compute-capable data centers and POPs. It also explains high availability features like regional failover for traffic and serverless functions, durable caching with stale-if-error states, backend failover using Edge Config for configuration updates without redeployment, and instant rollback to previous deployments. The post also mentions recurring resiliency testing for network infrastructure and security measures including managed infrastructure, data encryption, and threat detection.
