Team interview, University of L'Aquila

Developers can now focus only on coding the business-level logic

What is the new development paradigm for IoT and business service composition? 

uda_marco_autili.jpgMarco Autili, Assistant Professor:  As the Internet Network grows, the Internet of Services and Things is taking place. We daily experience the interaction with physical objects such as home alarm systems, thermostats, lighting bulbs, and other devices. These objects, which are not normally considered “intelligent”, are becoming smarter and smarter, and are programmed so as to be capable of independent computation and proactive actions. This capability allows these objects to communicate with each other as well as with software business services. Composing services and things spatially distributed over the Internet and coordinating their interactions in a distributed way is far from being simple if handled manually.
Hence, a new development and computing paradigm should offer dedicated modelling techniques, architectural style, integration patterns and middleware-level support to aid the automatic and distributed composition of business services and things.
Choreography-based development and choreography-oriented computation are good candidates towards supporting the realisation of such a paradigm in that choreographies represent an unambiguous and agnostic way of describing the relationships among business participants in a global peer-to-peer collaboration and supporting their distributed coordination.

Massimo Tivoli, Associate Professor:  
It is a paradigm promoting the flexible and easy reuse of existing services and things, and relieving the developer from accounting for composition and coordination issues.

What are the main benefits for software architect and developers to use service choreographies and, as a consequence of that, to use the CHOReVOLUTION platform? 

uda_massimo_tivoli.jpgMassimo Tivoli: On one hand, due to the inherently distributed nature of their software architecture, choreographies allow architects to build more scalable and efficient complex systems. On the other hand, developing concurrent and distributed systems introduces several issues. The main benefit, for choreography developers that use the CHOReVOLUTION platform, is to build choreographies by discarding possible service coordination, concurrency, and heterogeneity issues. That is, developers focus only on coding the business-level logic corresponding to the specified choreography tasks as taken in isolation.


Marco Autili: The adoption of service choreographies allows software architect and developers to have a global view of the system to be realised and focus on specifying how groups of business participants work together, identifying potential services and things that can play the roles of the identified participants, understanding and analyzing their interactions.
The CHOReVOLUTION platform is a ready-to-use integrated environment to design, synthesize, deploy and enact choreographies. Things are considered as first-class computation citizens and are seamlessly composed with business services despite possible heterogeneities in their business-level interaction protocols and middleware-level communication paradigms. Developers can focus only on implementing (or reusing when already existing) the internal logic of services and things. The CHOReVOLUTION platform will take care of producing the code needed to coordinate, adapt and secure the interaction among services and things, their deployment and enactment.

What skills are required to use the CHOReVOLUTION Studio? 

Massimo Tivoli: Basic knowledge of the ECLIPSE platform, business processes modelling through BPMN2 choreography diagrams, basic notion of service-oriented architectures and enabling technologies such as XML Schemas, WSDL, etc.

What key innovation do you bring? Where is the most challenging aspect in this development?  

Marco Autili: The flexibility and dynamicity come from the fact that CHOReVOLUTION choreographies run on the Cloud, and the project provides the needed middleware-level, monitoring, and run-time support to make a choreography dynamically adaptable to possible context changes. 

Massimo Tivoli: The main innovation brought by the CHOReVOLUTION approach and its related Studio concerns automatic support for a more easy realisation of choreographies by sparing developers from writing code that goes beyond the implementation of the business logic internal to single choreography tasks. These aspects have been appreciated by the industrial partners in that the approach permits to develop choreographies according to their daily development practices.

What are your responsibilities at UDA?

Team interview, VIKTORIA Swedish ICT

We are building a user application to demonstrate how the choreographies are used to coordinate traffic

How would you describe CHOReVOLUTION? 

Markus.jpgMarkus Millfjord, Senior Software Consultant: I would describe CHOReVOLUTION as a way to try to hide complicated things when you build service applications. Thanks to the project outcomes, you don’t need to deal with parallelism or threads anymore. You just have to focus on your business logic in order to design your service, then send a message as a result.

Cristofer Englund, Research Manager: CHOReVOLUTION is a platform where we integrate services of different kinds, and make them interact with each other to generate a nice and easy-to-use application. We’re using CHOReVOLUTION for transport applications. There are several needs to exchange information in a transportation system with traffic lights, car drivers, road infrastructures and the other road users (pedestrians, bikers…).

Lei Chen, Senior Researcher:  CHOReVOLUTION is a kind of distributed coordination method for web services. We’ve removed the central control unit, and we want all services running everywhere to coordinate themselves in a distributed way. CHOReVOLUTION provides such a method. Most of the present technologies are relying on orchestration, which means you have a unit that controls all the services. We need a more efficient solution for the huge number of connected things and for the data flows to be transmitted over the Internet. We think CHOReVOLUTION is potentially providing such a solution.

What is Viktoria Swedish ICT mission? 

Lei.jpg
Lei Chen: Viktoria Swedish ICT is one of the research institute in Sweden. We are working mostly in the transport sector, with industries and universities to bring sustainable transport solutions to the society.

Cristofer Englund: Viktoria Swedish ICT research institute is working on transport research within five key areas: electrified mobility, connected systems, business models, sustainable transports and how companies are digitizing their business.

What is your contribution to the project and where is it critical? 

Lei Chen: We are working on one of the use cases of the project, which is the Urban Transport Coordination. We are trying to provide a highly responsive traffic solution to the drivers, with real time information on the road situation, accidents, congestions, and providing the most eco-friendly route to help them reduce their carbon emission and save fuel. This is one of our sustainable path within the transport sector. We have a clear vision to develop the solution using the CHOReVOLUTION platform. The critical part in the project is that we are still in an initial development phase of the platform itself. 

What key innovation do you think CHOReVOLUTION is bringing? 

Markus Millfjord: It’s always nice to be able to separate how different services are interacting, and to make things cleaner. In the CHOReVOLUTION approach, the BPMN 2 choreography diagrams let you place the logic that makes sense in one context on one place and your business logic on a different place. From that perspective, improvements and fixes will be easier and as an end result the CHOReVOLUTION platform will make applications simpler to maintain.

In real life, for what kind of applications will you use service choreographies? 

Cristofer.jpgCristofer Englund: With the urban traffic control, we are building a user application to demonstrate how the choreographies are used to coordinate traffic. 

Markus Millfjord: In our use case, we are focusing on route suggestion. The platform can help you find the best route whatever are the conditions, from an eco-friendliness perspective. We’re trying to coordinate different services to gather information from public APIs, then we’re trying to add contents to these routes to compare them, to predict and to select which one is the best from the ecological perspective. The reason to use CHOReVOLUTION is its flexibility to be able to add more services, more data providers, including different kind of data to our business logic as a whole.

We are building an environment to create new advanced applications

Where does the CHOReVOLUTION project come from? 

This project was selected by the European Commission during the first Horizon 2020 call. It started in early 2015 and will extend for three years. Its development framework follows the results of another major project, CHOReOS which began to show how to create higher-level applications, integrating various services, in the field of smart city particularly. CHOReOS brought together the expertise of 17 partners between 2010 and 2013. It showed a great potential but also revealed a need for simplification so that its results can be easily exploited by smart city project managers. 

 
What is the purpose of the CHOReVOLUTION project?

CHOReVOLUTION aims to provide an environment allowing interactions between various services currently provided by local authorities, to deliver advanced applications based for example on traffic conditions or local weather information. Combined with business traveller objectives, for instance, this environment will calculate better routes and provide more accurate information directly on his smartphone. 

Where is the main innovation?

Today, several services and data sources are used for travel guidance. We're looking to provide a way to combine them in order to deliver a higher level of services. We want to offer the infrastructure to create these new advanced applications.

What role plays Thales in this project?

Thales is the project coordinator who ensures the achievement of the project objectives. There are eight partners involved, each having a complementary role. Some of them provide technologies and others develop tangible business cases to demonstrate how to use the CHOReVOLUTION environment in domains like intelligent transportation, smart city or energy savings.

What kind of resources Thales allocates to this project?

Thales provides human resources including a project manager and several engineers to secure the development of new applications.

Are you considering collaborations with other European projects?

Several practical workshops are already planned. Our goal is to foster exchanges at this point and to re-use, as much as possible, what has been done in the context of other European projects.
