Exploiting Stream Reasoning to Monitor multi-Cloud Applications

by Marco Miglierina, Marco Balduini, Narges Shahm, I Hoonejani, Di Nitto, Danilo Ardagna
"... Abstract. This demo shows how we have used a stream reasoning mechanism, C-SPARQL, as the main component of a Monitoring Platform for multi-Clouds applications, that is, applications replicated or distributed on multiple Clouds. The C-SPARQL engine executes monitoring queries on data gathered both f ..."

Quality Aspects and Challenges In Collaboration of Multi-Cloud- A Study

by Swetha D. M. Tech (scholar, Karnataka (state India
"... Abstract- Collaboration among services or application offered by different clouds is still restricted, the adoption of these technology will improve the ease of access from one provider to another and increase open challenges which avoid the vendor lock-in issues. As the number of services and provi ..."

and providers are increasing, the complexity of the overall system and the number of potential attacks will also increase. Preserving the security among multi-cloud is very important and trust among the providers is essential as the user often store sensitive information in cloud. Different providers will have

QoS-aware Virtual Machine Scheduling for Video Streaming Services in Multi-Cloud

by Wei Chen, Junwei Cao
"... Abstract: Video streaming services are trending to be deployed on cloud. Cloud computing offers better stability and lower price than traditional IT facilities. Huge storage capacity is essential for video streaming service. More and more cloud providers appear so there are increasing cloud platform ..."

platforms to choose. A better choice is to use more than one data center, which is called multi-cloud. In this paper a closed-loop approach is proposed for optimizing QoS and cost. Modules of monitoring and controlling data centers are required as well as the application feedback such as video streaming

CloudVisor: Retrofitting protection of virtual machines in multi-tenant cloud with nested virtualization

by Fengzhe Zhang, Jin Chen, Haibo Chen, Binyu Zang - IN PROC. OF ACM SOSP, CAS CAIS, PORTUGAL, , 2011
"... Multi-tenant cloud, which usually leases resources in the form of virtual machines, has been commercially available for years. Unfortunately, with the adoption of commodity virtualized infrastructures, software stacks in typical multi-tenant clouds are non-trivially large and complex, and thus are p ..."

AjaxScope: A platform for remotely monitoring the client-side behavior of web 2.0 applications.

by Emre Kıcıman , Benjamin Livshits - ACM Trans. Web , 2010
"... ABSTRACT The rise of the software-as-a-service paradigm has led to the development of a new breed of sophisticated, interactive applications often called Web 2.0. While web applications have become larger and more complex, web application developers today have little visibility into the end-to-end ..."

-to-end behavior of their systems. This paper presents AjaxScope, a dynamic instrumentation platform that enables cross-user monitoring and just-in-time control of web application behavior on end-user desktops. AjaxScope is a proxy that performs on-the-fly parsing and instrumentation of JavaScript code

Multi-tenant SOA middleware for cloud computing

by Afkham Azeez, Srinath Perera, Dimuthu Gamage, Ruwan Linton, Prabath Siriwardana, Dimuthu Leelaratne, Sanjiva Weerawarana, Paul Fremantle - In: Proceedings of the 2010 IEEE 3rd International Conference on Cloud Computing (CLOUD). IEEE , 2010
"... Abstract—Enterprise IT infrastructure incurs many costs ranging from hardware costs and software licenses/maintenance costs to the costs of monitoring, managing, and maintaining IT infrastructure. The recent advent of cloud computing offers some tangible prospects of reducing some of those costs; ho ..."
Abstract - Cited by 9 (0 self) - Add to MetaCart
; however, abstractions provided by cloud computing are often inadequate to provide major cost savings across the IT infrastructure life-cycle. Multi-tenancy, which allows a single application to emu-late multiple application instances, has been proposed as a solution to this problem. By sharing one

Towards a Monitoring Feedback Loop for Cloud Applications

by Piotr Bar, Rudy Benfredj, Jonathon Marks, Deyan Ulevinov, Bartosz Wozniak, Giuliano Casale, William J. Knottenbelt
"... Performance monitoring is fundamental to track cloud application health and service-level agreement compliance, but with the emergence of multi-cloud deployments, it may become increasingly important also to create a feedback loop between runtime operation in multi-clouds and design-time reasoning. ..."

Application QoS Monitoring and Benchmarking As-a-Service Framework

by Khalid Alhamazani, Rajiv Ranjan, Prem Prakash Jayaraman, Karan Mitra, Chang Liu, Fethi Rabhi, Dimitrios Georgakopoulos, Lizhe Wang
"... Abstract — Cloud computing provides on-demand access to affordable hardware (e.g., multi-core CPUs, GPUs, disks, and networking equipment) and software (e.g., databases, application servers and data processing frameworks) platforms with features such as elasticity, pay-per-use, low upfront investmen ..."

run-time Quality of Service (QoS) (e.g., latency and throughput). This paper proposes, develops and validates CLAMBS—Cross-Layer Multi-Cloud Application Monitoring and Benchmarking as-a-Service for efficient QoS monitoring and benchmarking of cloud applications hosted on multi-clouds environments

JCatascopia: Monitoring elastically adaptive applications

by Demetris Trihinas, George Pallis, Marios D. Dikaiakos - in the cloud, in 14th IEEE/ACM Int. Symp. Cluster, Cloud and Grid Computing , 2014
"... Abstract—Over the past decade, Cloud Computing has rapidly become a widely accepted paradigm with core concepts such as elasticity, scalability and on-demand automatic resource provisioning emerging as next generation Cloud service-must have- properties. Automatic resource provisioning for Cloud app ..."
Abstract - Cited by 3 (2 self) - Add to MetaCart
