Nikolaos Georgantas, INRIA Research Scientist presents the CHOReVOLUTION platform during the open cloud forum by OW2, in parallel of Cloud Computing World Expo, 22 March 2017, in Paris.

1. CHOReVOLUTION
Automated Synthesis of Dynamic and Secured Choreographies
for the Future Internet

Setting the context (cont’d)
distributed computing environments
large number of available services & Things
that can be composed
to meet user needs
Services will be increasingly active
software entities (peer-to-peer)

3. 3
Setting the context
● Service composition approaches
● Reusing services & Things into choreographies
Orchestration (centralized) Choreography (fully distributed)
support for automation is needed
(time-to-market, correctness by construction, etc.)
CHOReVOLUTION is about aiding system developers to realize, deploy,
execute, and monitor choreography-based systems by reusing existing services
and Things

The CHOReVOLUTION
platform is a toolbox of well-
integrated frontend
applications and backend
(middleware) components
enhanced by a flexible
cloud infrastructure.

6. CHOReVOLUTION Studio
The CHOReVOLUTION Studio is an
eclipse-based IDE that allows
choreography designers and service
providers to:
A. design a choreography exploiting
the CHOReVOLUTION notation
(based on BPMN2);
B. define all the details needed for
instrumenting the interaction among
the services involved in the
choreography (e.g. service
signatures, protocols, QoS, identity
attributes and roles)
C. drive the generation of Binding
Components, Security Filters,
Adaptors, and Coordination
Delegates exploiting the Synthesis
Processor and the eVolution Service
Bus (VSB) REST APIs

7. CHOReVOLUTION Console
The CHOReVOLUTION Console is
a web-based application that allows
choreography owners to:
A. configure, administer and
trigger corrective actions on
running services and
choreographies;
B. monitor the execution of a
choreography with respect to some
parameters of interest

8. CHOReVOLUTION Back-end
The CHOReVOLUTION backend
is composed by middleware
components that expose REST
APIs that:
A. generate the Concrete
Choreography specification
and all the related BCs, Ads,
CDs, SFs.
B. deploy, configure and
control BCs, Ads, CDs, SFs
on the CHOReVOLUTION
cloud infrastructure

C. manage authentication and authorization for services at run-time that uses different
security mechanisms at protocol level by storing different credentials on behalf of the caller and
managing authorization policies.
D. propagate/synchronize service/user profiles to/from external resources and provides
managed services

9. CHOReVOLUTION Cloud
All the described components aim at
putting into execution concrete
service choreography instances on a
cloud infrastructure and at adapting
the execution based on the actual
application context.
Thus, at execution time, for each
choreography, in the
CHOReVOLUTION cloud there are:
A. a set of choreography instances
at different execution states;
B. a set of virtual machines
executing a custom-tailored mix
of services and middleware
components to serve different
parts of the choreography.
