GENERAL OVERVIEW

What ARTIST is about

Mission

ARTIST aims at facilitating the transformation and modernization of legacy

software assets and businesses to the cloud.

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

The consortium

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

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

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”

Benefits of using Standards in our solution

For ARTIST tool producers:– Foster a wider uptake in the industry• Intermediate artefacts are interoperable

with other tools

–More credible– Be more competitive in the market

For ARTIST end users:– Increase productivity and efficiency– Increase revenues
