The blog post explores the process of creating a globally distributed, low-latency e-commerce application using Azure Cloud services, focusing on the use of Azure Cosmos DB for global data distribution and Pulumi for infrastructure management. It outlines how different teams within an organization can leverage various cloud compute services, like serverless functions, container instances, and virtual machines, while maintaining a unified global infrastructure. The post emphasizes the importance of microservices architecture, allowing teams the flexibility to choose their technology stack, and highlights the challenges of managing a geo-distributed application infrastructure. It introduces a custom Pulumi component, CosmosApp, designed to simplify the deployment of global web applications by providing a reusable abstraction for infrastructure management. This component enables teams to independently implement high-quality, region-specific compute services while ensuring consistency and reliability across the application.
