Cloud migrations require automation and configuration of new cloud infrastructure to reduce costs and free up resources for mission-critical innovation. Various tools are available to help with this process, including AWS CloudFormation, Puppet, Ansible, Chef, Kubernetes, Terraform, Google Cloud Deployment Manager, Microsoft Azure Automation, Cisco Intelligent Automation for Cloud, SaltStack, and VMware vCenter Configuration Manager (VCM). Each tool has its strengths, weaknesses, and learning curves, and the best choice depends on the specific needs of the project and teams involved. Combining two or more tools may be necessary to achieve maximum value from cloud infrastructure.
