Chef, Puppet, Ansible, and Salt are all popular configuration management tools. These tools help you install and manage software on existing cloud infrastructure, either for bootstrapping a virtual machine, or patching one. They do not attempt to solve the problem of provisioning or updating infrastructure, containers, or serverless resources.
Pulumi is fundamentally different than these tools and works great alongside them. Pulumi manages provisioning and updating of your cloud infrastructure and applications, including virtual machines, containers, databases, hosted cloud services, and serverless functions.
