WP2 Organogram & Input from other WPs

3. WP2 Outputs
Output 4 – Use Case Portfolio
Use Cases report developed through the pooling of the
experienced consortium portfolio of relevant use cases
necessary to achieve a comprehensive Policy &
Compliance requirements report (D2.4)
This would be a portfolio of 15 use cases from
government, research and business (D2.1 Use case report).
The report would address also EU legal and policy
requirements, including SLA management
WP2 could, if relevant and appropriate, draw from the use
cases developed within other external cloud requirements
gather processes
CloudWatch Review Period 1 34 November 2014

4. T2.1 Identify international Use Cases
& Open Collaborative Models
Objectives
Develop a framework for use case selection to identify and collect a portfolio
of international cloud use cases.
Map the landscape of cloud computing relevant to stakeholders in the EU
from enterprise, government, and science with special focus on SMEs.
Define a reference model and methodology for specifying and selecting cloud
use cases
Existing national, European and international use case collections identified
and analysed.
Check points: Internal report/deliverable “Cloud Use Cases for Europe”
identifying and describing the selected
use cases (month 5-6). This report will be a prerequisite to Task 2.2.
Task Leader: Fraunhofer
Participants: UOXF, CSA

5. Reference Model Framework Report
D2.1 Reference Model Framework Report defines the information model
to create a set of coherent use cases
Presentation of use cases
derivation of standardization requirements
development of standard profiles
Classification of use cases
Application domain: academic, industrial, public sector
Category: legal, organisational, technical
Stakeholders involved: the main actors that constitute the use case and their
responsibilities
Functions/components: The technical items within a cloud infrastructure or
related to a cloud service that are exercised in the use case
Based on ISO/IEC/ITU-T Cloud Computing Reference Architecture
International Standards ISO/IEC 17789 | Recommendations ITU-T Y.3502
“Information technology - Cloud computing - Reference architecture”

6. Cloud Computing Reference Architecture
Used to analyze which
aspects of cloud
computing systems
are addressed by a
particular use case
Based on
Roles: Provider,
Customer, etc.
Activities carried out
by actors assuming a
certain role
Functional
components used in
activities

7. Use Case Presentation Template
 Analysis of several aspects (legal,
organizational, technical) of
common usage scenarios
 Simplified template to be used for
use case acquisition
 Comprehensive presentation
templates for project internal use
(see D2.1)
Use Case
Title
Description Short summary of the use case
Goals and aspirations for the
use case
Background and main message of the use case; context of the use
case
Legal
aspects
Legal domain Data privacy regulations, licensing, contracting, etc.
Legal frameworks,
laws, etc., to be taken
into account
Laws, policies, etc. which are of relevance
Compliance criteria Explanation why the use case is an illustration on how legal
requirement can be implemented
Organizational
aspects
Organization domain e.g., security procedures, data privacy procedures, etc.
Regulations and
policies to be taken
into account
Policies, standards, best practices to be taken into account
Description of
organization
procedures
The “workflow” (or procedures) on organizational level used to
achieve the goal of the use case
Compliance criteria Explanation why the use case is an illustration on how
organisational requirement can be implemented
Technical
aspects
Preconditions Assumptions made prior to the execution of the use case
Criteria for success Expected process, outcome, and side-effects. Described by
sequence charts, etc.
Failure conditions and
responses
Description of what can go wrong, and what to do about it.
Existing specifications to rely
on
Specifications and standards already dealing with aspects related
to the use case
New specifications required Specifications and standards needed to establish the goals of the
use case
Additional comments Add comments, remarks, suggestions, as you see fit

8. D2.1 Reference Model Framework Report defines the information model to create a set of
coherent case-studies from three classes of user community: academic, enterprise and
public sector.
Community engagement workshop at the EC Concertation Meeting, Brussels 12/13 March
2014 – Making the Ecosystem Interoperable: Requirements Gathering & Future Steps. 46
projects represented.
Follow-up interviews with 15 selected projects from the three sectors.
To date;
Gather use cases to complete template, without analysis, interpretation, interference
or recommendations. [D2.2]
Document and analyse user stories derived from the use cases.
Identify commonalities, either within sector or cross sector and within cloud type
exploitation
Re-interview projects for answers to specific follow up questions
Inform the development of standards profiles within WP4 by capturing;
standards or common practices used within projects e.g. both cloud and non-cloud
but which are essential in the projects functioning
extensions or changes to those standards used within these projects, e.g. A&A in
some cloud standards
additional services or interfaces needing to be documented.
