Qué son Terraform 12 y Terragrunt y cómo se pueden aplicar a la infraestructura Multi-Cloud.
Hablaremos sobre el impacto de IaC (Infraestructura como código) en el mundo moderno y cómo Terraform lo ayuda a trabajar con entornos heterogéneos. Quiero discutir un poco sobre Terraform en sí, qué problemas tiene y cómo Terragrunt los resuelve. Luego hablaré sobre mi experiencia con Terragrunt y engancharé un poco sobre un tema como las nubes múltiples. En la segunda parte de la discusión sobre el tema, me gustaría mostrar el resultado de mis hallazgos al usar Terraform + Terragrunt en un entorno con tres proveedores de nube (AWS, GCP, Azure) y CloudFlare como DNS.
(Alexander) Hoy quiero hablar sobre cómo logré hacer la implementación de Multi-Cloud usando Terraform y Terragrunt, y cómo funciona en particular y por separado.
