3. GENERAL
OVERVIEW
What ARTIST is about

4. Mission
ARTIST aims at facilitating the
transformation and
modernization of legacy
software assets and
businesses to the cloud.

5. ARTIST at a glance
ARTIST helps in the process to modernise and
transform legacy software to run in the Cloud/SaaS,
and be offered through a new business model
Adapt legacy software to run on the cloud through
the creation of a set of methods, tools and techniques
based on Model Driven Engineering, accompanying
this technical modernization with business model
aspects and considering the impact in the
organizational processes
Help organisations to evaluate if their applications are
able (and if its worth it) to run these on the cloud and
perform the entire process to migrate the
applications: assess, plan, design, implement and
validate the migration process

6. The consortium

7. Approach
Tools to support the decision of
migrating or not and to which
cloud provider
• Maturity Assessment of the
application to be migrated. Current
vs. ideal maturity
• Technical Feasibility: High Level
Reverse Engineering + other metrics
such as code reusability potential
• Business Feasibility: Impact in the
business processes, Risks, ROI +
other metrics
PRE MIGRATION
Companies that sell their
application as a product
MIGRATION
Companies that are migrating
PROVISIONING
Companies that provide SaaS
Tools to support the migration
to SaaS
Technical Transformation
• Low-level reverse engineering
(KDM, UML2)
• IaaS / PaaS and 3rd party components
modelling (PDM)
• Forward Engineering, M2M / M2T
transformations (PIM to PSM to code
using PDM) (ATL)
• Migration Methodology + Supporting
guiding tools / templates (EPF, SPEM)
• V&V (behavioural and end users)
• methods and tools
Business Transformation
• Redefinition of business processes
• Definition of the business model
Tools to support the
SaaS provisioning
• V&V (behavioural and end
users) methods and tools
• Certification model for SaaS
application providers
• Repository of
artefacts, tools, etc. for easing
the evolution

8. Expected results
 A set of tools to analyse and classify legacy SW
and business and to evaluate
feasibility, cost, implications and benefits of
migration
 Methodology (tool-supported) to guide
companies in the entire migration process
(technical, business, process)
 Model-based approach for source/target
applications and infrastructures/platforms
 Reusable set of artefacts (models and
transformations) provided through an enhanced
repository
 A validation framework for migrated
applications
 A certification model for warranty the
compliance of migrated application with cloud
 Four validation scenarios (Java and .NET) to
demonstrate the feasibility of ARTIST results

9. Impact
 Up to 90% of software cost relates to its maintenance following
implementation…
 …yet once implemented it is never again cutting edge
ARTIST impact goal:
 To slash by 50% the migration cost relative to manual migration
 Permitting more frequent migration to more suitable platforms
 Mainly addressed to ISPs, software owners, cloud providers, etc.
“Balancing software continuity with optimal
performance and cost”
