What we talk about when we talk about cloud network performance

Jeffrey C. Mogul, Lucian Popa
2012 Computer communication review  
However, while all cloud providers provide network connectivity to tenant VMs, they seldom make any promises about network performance, and so cloud tenants suffer from highly-variable, unpredictable network  ...  Many cloud customers do want to be able to rely on network performance guarantees, and many cloud providers would like to offer (and charge for) these guarantees.  ...  We hope, in this paper, to bring clarity to this question: what kinds of network performance guarantees make sense, for both cloud customers and cloud providers?  ...

Approaches for Software Performance Modelling, Cloud Computing and Openstack

Deepali Gill, Hari Mohan Pandey
2015 International Journal of Computer Applications  
Performance modelling when applied on the cloud is again a very challenging task. For a good model for specific software we should have a good knowledge about the software working.  ...  This paper includes all the important performance modelling approaches. Along with this, we also have an overview of the cloud and Openstack environment.  ...  When we talk about the load and functional testing, the results in the form of the Boolean value either they pass or fail.  ...

Distributed Cloud Computing

Yvonne Coady, Oliver Hohlfeld, James Kempf, Rick McGeer, Stefan Schmid
2015 Computer communication review  
In this paper, we revisit the vision of distributed cloud computing, and identify different use cases as well as research challenges.  ...  This article is based on the Dagstuhl Seminar on Distributed Cloud Computing, which took place in February 2015 at Schloss Dagstuhl.  ...  Marc argued that what programmers really care about is a consistency model's properties: guarantees (i.e., what kind of application invariants are ensured automatically by a model), scalability (i.e.,  ...

Formal Foundations for Networking (Dagstuhl Seminar 15071)

Nikolaj Bjorner, Nate Foster, Philip Brighten Godfrey, Pamela Zave, Marc Herbstritt
2015 Dagstuhl Reports  
There is a growing need for tools and methodologies that provide rigorous guarantees about performance, reliability, and security.  ...  What are some techniques for handling the distributed systems issues that arise in modeling and reasoning about networks?  ...  We must reason about an aircraft as a network of avionics sub-systems, about a fleet as a network of aircraft, and about both of these being located in the cloud.  ...

Security Issues in Cloud Computing

Aayushi Tyagi
2017 International Journal for Research in Applied Science and Engineering Technology  
The biggest concern about cloud computing these days is its security i.ewhether the data put there is secured or not.  ...  Cloud computing allows companies to keep their resources online. This concept has helped lots of companies by reducing cost and providing flexibility.  ...  OAuth -What does OAuth mean [10] , told about this security standard in detail.  ...

IPDPS 2019 Technical Program

2019 2019 IEEE International Parallel and Distributed Processing Symposium (IPDPS)  
Are there concepts that can help guide us as we design applications and computer systems in a world that is untethered from familiar landmarks like center, cloud, edge?  ...  In 2001, as early high-speed networks were deployed, George Gilder observed that "when the network is as fast as the computer's internal links, the machine disintegrates across the net into a set of special  ...  In this talk we present our latest results using both approaches and draw some conclusions about their relative effectiveness and potential.  ...

2014 SMPTE Motion Imaging Journal  
Facilitating a conversation can be difficult if participants are talking about differ- ent aspects of the cloud. There are too many notions of what the cloud is.  ...  Unfortunately, it is often difficult to have a meaningful discussion about the cloud when speaking at a high level. It is a broad area to cover.  ...
