Otto, a tool developed by Hashicorp, aims to simplify Dockerized microservices development environments by abstracting complexity and enhancing productivity. It builds on the foundation laid by Vagrant, offering a unified deployment workflow that bridges the gap between development and production. Otto automates the management of application dependencies and leverages Docker to streamline the development process without altering the developer workflow, although it currently only supports containerizing dependencies rather than main applications. The tool uses Vagrant and Consul for local development and testing, with AWS and Terraform for infrastructure deployment. While Otto promises future support for Docker builds and tighter integration with Hashicorp's Nomad, it currently focuses on using AWS and AMIs for production deployment, with plans to expand its capabilities further.
