Otto was created to provide a high-level abstraction to both develop and deploy applications. Its goal was to unify HashiCorp tools across the application delivery spectrum, including Vagrant to manage development environments, Packer to build images, Terraform to provision images, Consul to connect and monitor applications, Nomad to deploy applications, and Vault to secure applications and infrastructure. It was an ambitious project, and we feel that it has not lived up to expectations. Rather than having a public project that does not meet HashiCorp standards, we have decided to close source the project so we can rethink its design and implementation. The source code is still available for download, but Otto will no longer be actively maintained or supported.
