Clemente Biondo, Engineering Ingegneria Informatica - When the COVID 19 pandemic started, Engineering Ingegneria Informatica Group (1.25 billion euros of revenues, 65 offices around the world, 12.000 employees) was forced to put their digital transformation to the test in order to maintain operational continuity. In this session, Clemente Biondo, the Tech Lead of the Information Systems Department, will share how his company is reacting to this unforeseeable scenario and how Docker-driven digital transformation had paved the path for work to continue remotely. Clemente will discuss learnings moving from colocated teams, manual approaches, email based-business processes, and a monolithic application to a mature DevOps culture characterized by a distributed autonomous workforce and a continuous deployment process that deploys backward-compatible Docker containerized microservices into hybrid multi cloud datacenters an average of twice a day with zero-downtime. He will detail how they use Docker to unify dev, test and production environments, and as an efficient and automated mechanism for deploying applications. Lastly, Clemente shares how, in our darkest hour, he and others are working to shine their brightest light.

9. A DevOps workplace - Docker
Before Docker work remotely meant:
▪ constant use of one or more VPNs
▪ remotely connect to the test/prod
machines
▪ manual operations
DOCKERCON 2020
With Docker:
▪ a reproducible development
environment
▪ same container in dev, test and prod
▪ an "integration environment" that
runs locally
▪ replace stubs with real services
▪ Pre-canned images, readily
accessible and shareable
▪ Immutable infrastructure

perspective the user
▪ It captures WHO is the user, WHAT he wants
and WHY
▪ It’s a placeholder for a conversation
▪ It delivers value to the end user
▪ Should be doable in a couple of days max
▪ It's accompanied by its acceptance criteria

27. Make frequent releases, multiple times a day with small functionality increments.
Feature flag: new functionalities should be enabled / disabled live, via configuration, without
deploying new code.
Open Close principle: software should be open for extension, but closed for modification.
Design to maximize reversibility and resilience.
KISS principle: simplicity should be a key goal.
The risk level of the release is strongly correlated with the quality of the Test Suite.

The main evolutions of our Roadmap are proceeding both in
terms of integration with information systems and with the
evolution of the catalogue:
▪ Enriching the IaaS offer with new services (e.g. Disaster
Recovery aaS, Business Continuity aaS, etc.)
▪ Enabling new suppliers (e.g. Google, Alibaba, Oracle, etc.)
- from today connectors for Azure and AWS are available)
▪ Enrich the PaaS offering with new platforms and Container
as a service by integrating Docker technology into a
container cluster system
▪ Create new SaaS offerings to add to the catalog based
also on Docker technology

47. ▪ It is our biosurveillance solution that maps and geolocates
infected subjects, who has come into contact with them and
the presence of clusters that require high attention
▪ Based on our Digital Enabler ecosystem platform
▪ Inform in real time about the state of the infected population
▪ Monitors the spread of the virus among health workers
▪ Provides a relationship service that identifies those likely to
be exposed to the infection
▪ Provides a service that identifiesinfos in order to reconstruct
the clusters of possible infected
▪ Obviously it runs on Docker containers
