\begin{abstract}
This paper describes the achievements of the H2020 project INDIGO-DataCloud in the field of software lifecycle management, the Continuous Integration and Delivery systems setup to manage the new releases, as a first step towards the implementation of a DevOps approach.
Cloud@CNAF is a project aiming to offer a production quality Cloud Infrastructure, based on open source solutions to serve the different CNAF use cases.
The project is the resultof the collaboration of a transverse group of people from all CNAF departments: network, storage, farming, national services, distributed systems.
If 2016 was for the Cloud@CNAF IaaS (Infrastructure as a Service) based on OpenStack [1], a period of consolidation and
improvement, 2017 was the year of the flood, when an aqueduct pipe located inthe street nearby CNAF, went broke causing the down of the entire datacenter.
This paper presents the activity carried out throughout the year in the migration
from the point of view of stabilityand reliability, in which the activities were focused on the support of the operation of theinfrastructure, definition of monitoring
checks, dashboards and notifications, integration in thegeneral CNAF provisioning and monitoring system. During this period the number of supportedusers and uses cases has increased,
and as a consequence, the infrastructure saw a grouth ofthe resources allocated. Work on the preparation of a parallel cloud infrastructure also started,infrastructure dedicated to the
testing of OpenStack upgrade procedures, usually a complex anddifficult task. This paper presents the activity carried out throughout the year in the directionsmentioned and gives also a
vision on the future evolution foreseen for the cloud infrastructureat CNAF.

\section{Introduction}
Text
The main goal of Cloud@CNAF project is to provide a production quality
Cloud Infrastructure for CNAF internal activities as well as national and
international projects hosted at CNAF:
\begin{itemize}
\item Internal activities
\begin{itemize}
\item Provisioning VM for CNAF departments and staff members
\item Provisioning of VM for CNAF staff members
\item Tutorial and courses
\end{itemize}
\item National and international projects
\begin{itemize}
\item Providing VMs for experiments hosted at CNAF, like CMS, ATLAS, EEE
\item testbeds for testing the services developed by projects like the OpenCityPlatform \& INDIGO-DataCloud
\end{itemize}
\end{itemize}
The infrastructure made available is based on OpenStack, version Juno, with all the
services deployed using a High-Availability (HA) setup or in a
clustered manner (for ex. for the DBs used). During 2016 the infrastructure has been
enhanced, by adding new resources, compute and network, and its operation has been improved and guaranteed by
adding the monitoring part, improving the support, automating the maintenance activities.
