Resilient Multi-Cloud Deployment Validation Framework

Develop a sophisticated Bash script that performs comprehensive deployment validation across different cloud providers and infrastructure configurations. The script must dynamically test deployment readiness by checking network connectivity, validating infrastructure-as-code configurations, running security compliance checks, and generating detailed reports. Include support for AWS, Azure, and GCP, with the ability to simulate deployment scenarios, validate resource configurations, and provide actionable remediation recommendations. Implement advanced error tracking and automated rollback mechanisms.
