Cloud Platforms
Cloud platforms have revolutionized data engineering by providing managed services that eliminate infrastructure complexity while offering unprecedented scale and flexibility. Modern cloud data platforms enable organizations to focus on business logic rather than infrastructure management.
Cloud-Native Philosophy
Cloud platforms embrace several key principles that distinguish them from traditional on-premises solutions:
Serverless-First Approach
Eliminate server management by using services that automatically scale based on demand.
Pay-per-Use Model
Cost optimization through granular billing based on actual resource consumption.
Managed Services
Reduce operational overhead by leveraging fully managed database, analytics, and ML services.
Multi-Region Availability
Built-in disaster recovery and global data distribution capabilities.
