GitOps: Building the next generation infrastructure

Descripción general

Cloud computing and security merged together in order to create a new paradigma in environments orchestration. It's not only about the code, it's mainly about methodologies to lean any organization to embrace good practices and deploy environments in a resilient way. How security can be enforced across all organization? What's the DevSecOps role in any modern organization?.  How observability and traceability can help to reduce the impact?
