Remote Provisioning Service is a service offered by phones vendors for easily and quickly provide a configuration for a phone. Despite the advantages of have a phone ready to use without any specific network configuration (except for a internet connection), there are some drawbacks like different APIs for any vendors. Falconieri try to unify all the vendors specific APIs under a set of HTTP rest APIs.

In this talk will be shown the motivations beoynd the creation of Falconieri and the technical choises. Will be illustrated also the APIs of the four currently supported vendors:

• SNOM
• Gigaset
• Yealink
• Fanvil

Immutable infrastructure paradigm is often associated with relative new concept like containers and orchestrators like kubernetes. In this talk will be illustrate how to obtain the same result but using most of the classic concepts, tools and simple cloud platforms.

In particular will be shown the usage of:

• Terraform for the orchestration
• Packer for the creation of the instance image
• Simple shell scripts for the provisioning
• DigitalOcean as cloud platform

The illustrated approach is based on lessons learned in almost two years of using this methodology on a production service.

Prometheus, at first look, can appear very simple and at the same time very complicated, in this talk will be illustrate how a small/medium IT company can approach the deployment of the prometheus stack (Prometheus, Grafana, alertmanager and exporters), start from the local testing environment and ansible roles, to the targets labeling and exporters configurations. Will be also outlined the benefits that Prometheus can give to a company in terms of metrics visibility, the easiness to plug in new systems for generic metrics collections and the knowledge sharing, without necessary be used for monitoring dynamic and complex systems.

In this talk will be illustrate who to manage a DNS infrastructure with a git repository and pull requests, will be also show how to easy setup multiple zones backup with multiple DNS providers. All make possible with octodns and travis-ci.
