Tasks meet flows: Merging two paradigms in a Cloud applications development platform

Gustavo Alves Everton Cavalcante Frederico Lopes Ernani Azevêdo Ramide Dantas

In this paper we present a new architecture for the Cloud Integrator platform that extends it in two directions. The first one aimed at improving the way of an application can be defined by a developer. Instead of dealing with the burden of defining applications only by specifying semantic workflows in terms of activities expressed as a tuple , a developer can rely on the definition of complete executions flows or partial execution flows. The second extension aimed at the automatic deployment of applications in a cloud platform, thus allowing the simultaneous use of it by several clients over the Internet. We also present a proof-of-concept that illustrates the use of the cloud-based platform in a flight booking application.

Policy Processing: Don't Take it for Granted

IEEE International Symposium on Policies for Distributed Systems and Networks (2009)

Joseane Fidalgo Carlos Kamienski Ramide Dantas Djamel Sadok Börje Ohlman

The new advanced services and limitations of current Internet have driven a lot of initiatives in architectures for future Internet. Ambient networks is one of these initiatives, focused in providing a seamless cooperation of resources in an environment with a multitude of access technologies, network operators and business actors. There are many efforts using policy based management as a practical solution for addressing the challenges for the management of future Internet such as cross-domain management, integration and manipulation of data across the world, seamless mobility, reliability, performance and heterogeneity support. However, not much attention has been given to the policy processing itself. In this paper we present our policy processing system, currently used in the PBMAN project, a policy based management architecture and prototype for Ambient Networks. The primary contribution of this paper is to give real attention to the components of policy systems that can determine its performance as well as its successful adoption.

Advancing IoT-Based Smart Irrigation

IEEE Internet of Things Magazine (2019)

Rodrigo Togneri Carlos Kamienski Ramide Dantas Ronaldo C. Prati Attilio Toscano

Integrated Internet of Things (IoT) platforms are needed for realizing IoT potential in commercial-scale applications. The main challenge is to provide solution flexibility to meet custom application needs. We developed an IoT-based platform for smart irrigation, with a flexible architecture to easily connect IoT and machine learning (ML) components to build application solutions. Our architecture enables multiple and customizable analytical approaches to precision irrigation, making room for the improvement of ML approaches. Impacts on different stakeholders can be anticipated, including IoT professionals, by facilitating system deployment, and farmers, by providing cost reduction and safer crop yields. Examples are given based on pilots in Europe and Brazil.

Facilitating Service Creation via Partial Specification and Automated Composition

Ramide Dantas Ernani Azevêdo Cyrus Dias Thiago Lima Djamel Sadok

Service composition is an important feature enabled by Service Oriented Computing but it remains mainly a manual process. Proposals for complete or partial automation of composition exist, the majority relying on artificial intelligence-based planning, automated proof techniques, or graph-based solutions. Although sound, these approaches present practical issues that prevent their use in production scenarios. This paper presents a composition tool that allows for partial service specification along with a composition algorithm based on the semantic matching of services inputs and outputs. Early performance numbers are also presented.

XACML-Based Composition Policies for Ambient Networks

Carlos Kamienski Joseane Fidalgo Ramide Dantas Djamel Sadok Börje Ohlman

Ambient Networks (AN) pose new challenges to the management discipline, and policies are considered to be an adequate solution for providing flexibility, distributed control, and self-management features. However, the current state-of the art IETF policy framework was not designed for the challenges of new 3G/4G environments such as AN. This paper presents PBMAN, a policy-based architecture and a composition framework that extends the AN architecture, where policies are intrinsically at the underlying layer by design and not as a later ad-on. The use of policies and their interaction with network composition is the main research challenge of PBMAN. The current architecture has been designed based on previous experience, on a design-implement-test development cycle. The framework was used to model a video on demand scenario, whereto composition policies based on an extended version of the XACML policy language have been written.

Design and implementation of a policy-based management framework for Ambient Networks: Choices and lessons learned

Carlos Kamienski Joseane Fidalgo Ramide Dantas Djamel Sadok Börje Ohlman

The management of large-scale 3G and 4G wireless systems, such as ambient networks (AN), in the Internet is a challenge, due to their inherent heterogeneous and distributed nature. In this paper we present our experience with the design and implementation of PBMAN, a Policy-based Management framework for AN, which gives special attention to network composition. We discuss the main choices as well as the lessons we learned during this process and the next steps.

Effective implementation of network composition for ambient networks

Ramide Dantas Joseane Fidalgo Jennifer Lima Djamel Sadok Carlos Kamienski

Ambient Networks propose the concept of network composition for providing dynamic and instant resource access for roaming users. policy-based management (PBM) is a good candidate for a service management platform in such scenarios. However, PBM infrastructures for large-scale service management in 3G/4G environments are still to be developed. This paper presents a prototype implementation of a PBM approach for network composition that uses a tree-based information model mapped on a peer-to-peer storage mechanism. A preliminary, measurement-based performance analysis of the prototype is presented along with a discussion on the strategies used, their benefits and pitfalls.

A path to automated service creation via semi-automation levels

Journal of the Brazilian Computer Society (2014)

Ernani Azevêdo Carlos Kamienski Ramide Dantas Börje Ohlman Djamel Sadok

The manual creation of new Internet- and IT-based applications is currently a limiting factor in enabling new and innovative services to be quickly available. We advocate that semi-automated service creation techniques are feasible, whereas fully automated ones are not a reality yet. Consistently increasing the level of automation may lead to a better comprehension of the problem that will pave the way for the introduction of higher levels of automation in the future. We have developed two versions of a service creation tool, with different levels of automation, which have so far confirmed our expectations that the experience with semi-automation is a promising approach for continually speeding up the service creation process.

Workflow specification and scheduling with security constraints in hybrid clouds

Daniel S. Marcon Luiz F. Bittencourt Ramide Dantas Miguel Neves Edmundo R. M. Madeira

Hybrid cloud management must deal with resources from both public and private clouds, as well as their interaction. When workflows are executed in a hybrid cloud, dependencies among their components bring new factors to be considered during specification, scheduling, and virtual machine provisioning. In this paper, we describe three components, namely workflow code, scheduler, and resource allocator, which enable the specification and execution of workflows in hybrid clouds in the context of the AltoStratus middleware. We present a case study that shows the interaction among these components, and their applicability in practice.
