Postdoc position – PaaS Cloud Service for the Deployment and Execution of Mobile Social Applications

Scientific Advisor:

Place of Work:

  • Inria Team MYRIADS, Inria Rennes – Bretagne Atlantique

Postdoc research focus:

In urban environments, a lot of data is continuously collected, originating from a variety of sensors and from people’s smart devices. We can foresee that mining and learning from the rich and various data generated in cities from different sources (sensor networks, smart devices, open data) will lead to a new generation of mobile social applications. Clouds provide infrastructures of choice to store and process collected data, as cloud resources can be dynamically provisioned on-demand in self-service. As the volume and velocity of data to be stored and processed may vary over time, cloud-based elastic data management services are needed to enable near real-time processing of data coming from sensor networks and smartphones possibly combined with other data such as open data. The data processing chain may involve filtering, aggregating and ultimately storing resulting data for further processing by data analytics applications.

Many stakeholders are involved in the collection and the storage of data from sensor networks, smart devices and open data and in the provision of services and applications for citizens and city government. Thus, multiple private and public cloud providers are likely to be involved providing storage and computation services to urban services and applications. This calls for elastic cloud-based services, which are portable on different clouds and can be deployed on several clouds.

This objective of the proposed work is to design and implement a Platform-as-a-Service (PaaS) environment to easily program, deploy and efficiently execute cloud-based urban-scale applications involving urban and social data sensing and analytics. A PaaS-as-a-Service runtime environment dedicated to mobile social applications in the context of smart cities should provide the following features:

  • Algorithms and mechanisms to seamlessly off-load computing tasks and storage from static and mobile smart devices into the cloud,
  • Protocols for efficient data transfer from the sensors and smart devices to the services running in the cloud,
  • Elastic services for data streams processing in near real-time,
  • Elastic services for data analytics.

The design of the envisioned PaaS raises a number of challenges in terms of scalability with the number of users, devices, services, data streams, ease of deployment of the cloud-based urban services and mobile social applications, elasticity management of the data stream processing [Ananthanarayanan13] and data analytics services and flexibility and extensibility.

The work will be divided in the following steps:

  • Study the software architecture of urban services and mobile social applications and their underlying middleware [Hachem14].
  • Propose a PaaS cloud environment providing a simple web interface and API for the development and deployment of mobile social applications [Moreno-Vozmediano 2013]. The proposed PaaS cloud environment could leverage ConPaaS PaaS [Pierre 2012, ConPaaS] and customize it to the needs of mobile social applications.
  • Design and implement algorithms and mechanisms to seamlessly off-load computation tasks and storage from mobile devices into the cloud.
  • Design and implement protocols for efficient data transfer from sensors and smart devices to the services running in the cloud,
  • Integrate auto-scaling services in the PaaS environment (i) to process data streams in near real-time [Storm] and (ii) to perform efficient data analytics.
  • Validate the proposed PaaS with some of the next generation urban services and mobile social applications developed within CityLab@Inria (see https://citylab.inria.fr). Experiments will use the Grid’500 experimentation platform [G5K] and other testbeds as needed.
