☁️ Cloud-Native Development with TuskLang & PHP
Introduction
Cloud-native development is the future of scalable, resilient applications. TuskLang and PHP let you build sophisticated cloud-native systems with config-driven containerization, orchestration, and monitoring that thrives in modern cloud environments.Key Features
- Containerization with Docker - Kubernetes deployment - Service mesh integration - Cloud-native databases - Monitoring and observability - CI/CD pipelines - Auto-scaling and resilienceExample: Cloud-Native Configuration
