This document presents an initial system specification of the Melodic Multi-Cloud middleware platform. The document covers two important areas necessary for the subsequent development of the Melodic platform: Requirements Analysis and Technology Evaluation. The requirement analysis is essential to establish a set of initial features needed to realise an efficient middleware platform for Cross-Cloud dataintensive computing. At the same time, a complete evaluation of the available open technologies ensures that the efforts in the Melodic project are directed towards providing technology and tools that are currently beyond state-of-the-art and stateof-the-practice, and not on re-engineering solutions already available from other European and international open source projects. Based on the requirement analysis, considering both the perspective of the general data-intensive Cloud applications as well as the needs of the four Melodic use-cases, a set of functional and non-functional requirements are presented in this document. In addition, technical and business-level constraints imposed by private and public Cloud solutions are identified for the Melodic middleware platform. Moreover, a comprehensive technology evaluation comprising identification of reusable components from three identified EU projects (PaaSage, CACTOS, and PaaSword) and available big data technologies are presented in detail – together with the identified extensions needed for Melodic. The requirement analysis and the technology evaluation together resulted in a preliminary architecture of the Melodic middleware platform. This preliminary architecture, as presented in this document, will lay the foundation of the first Melodic release, the integration release, due by the end of the first year of the project.

D2.2 Architecture and initial feature definitions

The Architecture definition will detail and explain the overall architecture of the MELODIC middleware, and in particular describe the key components of MELODIC, and how these components are to interact and collaborate in order to realise an efficient multi-cloud middleware platform for data-intensive applications. In addition, the initial feature definition of MELODIC will be provided.

D2.3 Final framework and external APIs

D4.1 Provider agnostic interface definition & mapping cycle

This deliverable focuses on the provider agnostic interface definition and mapping to the system requirement analysis of D2.1. Representing the first iteration this definition and mapping cycle a first prototype of the provider agnostic interface mapper is developed. This prototype builds the starting point for the resource management framework and it is also evaluated against the the first draft of the resource management framework.

D4.2 Provider agnostic interface mapper

It revisits the provider agnostic interface definition to provide an interface for the Upperware, including management and monitoring capabilities. This first iteration of the resource management framework also includes the completed integration of PaaSage and CACTOS components.

D4.4 Resource Management Framework

This deliverable finalises the resource management framework. It revisits the prototype of D3.3 and refines the resource management framework due to lessons lerned during the development of the data processing layer and the Upperware. The resource management framework is evaluated using of the data processing layer.

D4.5 Data processing layer prototype

This deliverable describes the first iteration of the data processing layer resulting in a first prototype. Based on D4.1 and the parallel development of the rsource management framework it lifts a first data processing engine on top of the resource management framework and implements a first version of the data storage infrastructure. This first prototype is evaluated against the first iteration of use case implementation (D6.2).

D4.6 Data processing layer

This deliverable finalizes the data processing layer. It revisits the resource management framework for refining necessary changes and extensions to the data processing layer and also integrating further data processing engines into the data processing layer. The validation of the final data processing layer is based on the 2nd iteration of the use case implementation (D6.3).

Authors: Antonia Schwichtenberg, Katarzyna Materka, Kyriakos Kritikos, Paweł Skrzypek, Michał Semczuk

The efficient and appropriate usage of existing opensource software in Melodic needs a careful study with respect to the changes and adaptations required for their integration with Melodic. This deliverable is aimed at identifying such changes. The frameworks reviewed in this deliverable include PaaSage and Cactus/Cloudiator. The review methodology is designed based on existing functional and non-functional features in each framework and the assessment of implementation code for each framework. The functional features are studied based on the objectives of Melodic: multi-cloud deployment of applications, cloud-agnostic description of applications and infrastructures, and support for data awareness and data locality, to name the most important ones. Performance, reliability, maintainability, and serviceability are among the important non-functional features considered in our methodology. The code assessment is performed by verifying the quality of the code against best programming practices as well as quality assurance requirements. We use the Clean Code approach as the best programming practice for evaluation.

D5.03 Security requirements & design

This deliverable will provide a specification of security requirements of the MELODIC framework and the design of the security technical component.

A careful design of the Melodic integration strategy is very important as the main mission of Melodic is to integrate and adapt underlying frameworks, including PaaSage and CACTOS. This deliverable provides a detailed description of the requirements of this integration. The methodology for collecting integration requirements focuses on identifying the requirements separately for Control & Data Plane and Monitoring Plane. The other key set of requirements is functional testing and UI components testing, which specifies rules and conditions verifying the proper implementation of respective functional features of the Melodic system. The functional testing requirements are provided in the form of testing scenarios, which should be executed for a given Melodic release. These scenarios include initial deployment testing, global reconfiguration & local reconfiguration testing, metric management testing, reasoning related testing, and API testing. D2.1 "System specification" and use-case application descriptions are two main sources of identifying testing requirements. Apart from functional, also non-functional testing requirements are covered to verify the proper implementation of the nonfunctional features of the Melodic system. The nonfunctional testing scenarios include fault handling testing, performance testing, security testing, and other nonfunctional testing.
