DITAS Cloud Platform allows developers to design data-intensive applications that can run across cloud and edge devices in an optimal way by exploiting data and computation movement strategies. It provides tools like the DITAS SDK and DITAS Execution Environment to support designing, deploying, running, and monitoring distributed applications that leverage DITAS Virtual Data Containers to abstractly define and access data across different infrastructure providers.

1. DITAS Cloud Platform allows developers to design
data-intensive applications, deploy them on a mixed
cloud/edge environment and execute the resulting
distributed application in an optimal way by exploiting the
data and computation movement strategies, no matter the
number of different devices, their type and the
heterogeneity of runtime environments. It brings to your
developer toolbox the best of Cloud & Edge worlds.

Data Data can be stored and processed not only on
the cloud but also on more dynamic, numerous and
heterogeneous resources including various types of edge
devices (e.g., Raspberry PI, Intel Galileo, Arduino,
smartphones) and in more powerful devices (e.g. laptop,
small servers, cloudlets, and many others).
To properly manage this new ecosystem of connected things,

The initiative is being undertaken by global service providers Atos
(Spain), IBM (Israel) and Cloud Sigma (Switzerland); and European
companies IK4-DEKO (Spain) and Ospedale San Raffaele (Italy);
and researchers from leading European institutions like Politecnico
di Milano (Italy), Technical University of Berlin (Germany) and
Institute of Communications and Computer Systems (Greece).
DITAS Cloud Platform extends the classical IaaS with
an infrastructure able to offer computational and storage
resources, residing on both the edge and the cloud.

2. DITAS Practical Tools for
Data-Intensive Apps
DITAS Cloud Platform provides two main tools: DITAS
SDK in charge of supporting design and deployment,
and DITAS Execution Environment, a distributed
execution environment responsible for running and
controlling the behavior of the application powered
by DITAS Virtual Data Containers

DITAS SDK provides extensions of
popular tools such as Node-RED
to define applications.
The key element of this tool is to
allow developers to design
applications by specifying Virtual
Data Containers (VDC s) and
constraints/preferences for Cloud
& Edge resources to be exploited.
Applications are then deployed
satisfying all constraints based on
developer’s instructions and the
degree of freedom given by the
VDCs.
DITAS EE is based on our
powerful execution engine
capable of managing a
distributed architecture and
taking care of data movement
and computation, maintaining
coordination with other resources
involved in the same application.
DITAS EE also has a monitoring
system capable of checking the
status of the execution, track data
movements, and collect all data
necessary for understanding the
behavior of the application.
VDCs provide an abstraction layer for
developers so they can focus only on data, what
they want to use and why, forgetting about
implementation details. With VDCs applications
can easily access required data, in the desired
format and with the proper quality level, rather
than directly searching for and accessing them
among various data infrastructure providers.
At design-time, VDCs allow developers to simply
define data requirements, quality and how
important data is. At run-time, VDCs are
responsible for providing the right data and
satisfying requirements by hiding the complex
underlying infrastructure composed of different
platforms, storage systems, and network
capabilities.
