Abstract

 
 
 How to deploy and manage, in an efficient and adaptive way, complex applications across multiple heterogeneous cloud platforms is one of the problems that have emerged with the cloud revolution. In this paper we present context, motivations and objectives of the EU research project SeaClouds, which aims at enabling a seamless adaptive multi-cloud management of complex applications by supporting the distribution, monitoring and migration of application modules over multiple heterogeneous cloud platforms. After positioning SeaClouds with respect to related cloud initiatives, we present the SeaClouds architecture and discuss some of its aspect, such as the use of the OASIS standard TOSCA and the compatibility with the OASIS CAMP initiative.
 
 
Highlights
Cloud computing is a model for enabling convenient and on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction [1]
After the deployment is performed, and components are being executed in different cloud platforms, a monitoring process is in charge of detecting possible requirements violations, which could eventually trigger a reconfiguration
By simplifying the development process with SeaClouds’ range of tools and framework that require minor impact on the code, and second, by simplifying the management of already deployed complex cloud applications thanks to with SeaClouds dashboard. 4.2 SeaClouds architecture We present the SeaClouds reference architecture, and discuss its novel aspects compared to previous initiatives and efforts. 4.2.1 Description Before describing the core components of the architecture of the SeaClouds platform (Figure 5), it is worth observing that the platform features a graphical user interface (GUI) for two user roles (Designers and Deployment Managers)
Summary
Cloud computing is a model for enabling convenient and on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction [1]. In a scenario where a complex application is distributed on different cloud service providers, a solution is needed in order to manage and orchestrate the distribution of modules in a sound and adaptive way. Such solution should determine the best cloud provider for each particular module based on client requirements (e.g., availability, cost). SeaClouds will be able to deploy, manage, scale and monitor services over technologically diverse clouds providers Such operations will be performed by taking into account the synchronization requirements of the application as a whole and by providing developers with support beyond the handling of single services. 1http://www.enstratius.com/ 2http://www.bmc.com/ 3http://www.abiquo.com/ 4The present paper is an extended version of [9], and it provides an updated progress report on the evolution of the project w.r.t.
