Positioned in the gap between Heroku and Chef/Puppet, Serene Machine is "configuration done right" for servers in the cloud and in the datacenter. In 5 minutes, servers are configured for maximum security, availability, and scalability. All off-machine resources that support the configuration (e.g., nagios/sensu, logstash, backup storage, etc.) are hosted on Serene's high security, high availability infrastructure. A free plan covers small installations and lets engineers test drive the service. Larger plans charge a modest monthly per node fee. Serene brings developers the ease of use of Heroku with the flexibility of Chef and Puppet.
