InterCloud: Scaling of Applications across multiple Cloud Computing Environments March 20, 2010

Posted by Rajkumar Buyya in Cloud Computing, CLOUDS Lab News.

InterCloud: Utility-Oriented Federation of Cloud Computing Environments for Scaling of Application Services

Rajkumar Buyya, Rajiv Ranjan, Rodrigo N. Calheiros

Cloud computing providers have setup several data centers at different geographical locations over the Internet in order to optimally serve needs of their customers around the world. However, existing systems do not support mechanisms and policies for dynamically coordinating load distribution among different Cloud-based data centers in order to determine optimal location for hosting application services to achieve reasonable QoS levels. Further, the Cloud computing providers are unable to predict geographic distribution of users consuming their services, hence the load coordination must happen automatically, and distribution of services must change in response to changes in the load. To counter this problem, we advocate creation of federated Cloud computing environment (InterCloud) that facilitates just-in-time, opportunistic, and scalable provisioning of application services, consistently achieving QoS targets under variable workload, resource and network conditions. The overall goal is to create a computing environment that supports dynamic expansion or contraction of capabilities (VMs, services, storage, and database) for handling sudden variations in service demands.

This paper presents vision, challenges, and architectural elements of InterCloud for utility-oriented federation of Cloud computing environments. The proposed InterCloud environment supports scaling of applications across multiple vendor clouds. We have validated our approach by conducting a set of rigorous performance evaluation study using the CloudSim toolkit. The results demonstrate that federated Cloud computing model has immense potential as it offers significant performance gains as regards to response time and cost saving under dynamic workload scenarios.

CloudAnalyst: A CloudSim-based Visual Modeller for Analysing Cloud Computing Environments and Applications October 25, 2009

Posted by Rajkumar Buyya in Cloud Computing, CLOUDS Lab News.

Title: CloudAnalyst: A CloudSim-based Visual Modeller for Analysing Cloud
Computing Environments and Applications
Authors: Bhathiya Wickremasinghe, Rodrigo N. Calheiros, and Rajkumar Buyya
Report-no: Technical Report, CLOUDS-TR-2009-12, Cloud Computing and Distributed Systems Laboratory, The University of Melbourne, Australia, Oct. 23, 2009


Advances in Cloud computing enable new possibilities to Internet applications
developers. Previously, the main concern of Internet applications developers
was deployment and hosting of applications, because it required acquisition of
a server with a fixed capacity, able to handle the expected application peak
demand, installation of the whole software infrastructure of the platform
supporting the application, and configuration of the application itself.
Furthermore, server was underutilized because peak traffic happens only at
specific times. With the advent of the Cloud, solution of this problem became
cheaper and easier with the use of pay-per-use, flexible elastic infrastructure
services offered by Cloud providers. Because several Cloud providers are
available, each one offering different pricing models and located in different
geographic regions, a new concern of application developers is selecting
providers and data center locations for applications. However, there is a lack
of tools that enable developers to evaluate requirements of large-scale Cloud
applications in terms of geographic distribution of both computing servers and
user workloads. To fill this gap in tools for evaluation and modeling of Cloud
environments and applications, in this paper we propose CloudAnalyst. It was
developed to simulate large-scale Cloud applications with the purpose of
studying the behavior of such applications under various deployment
configurations. CloudAnalyst helps developers with insights in how to
distribute applications among Cloud infrastructures and value added services
such as optimization of applications performance and providers incoming with
the use of Service Brokers.

CLOUDS Lab to Release GridSim Toolkit 5.0

The Cloud Computing and Distributed Systems (CLOUDS) Laboratory at
the University of Melbourne, Australia has released the next-version of
Grid simulation software, the GridSim Toolkit 5.0.

This new version of GridSim brings a new package (i.e. gridsim.parallel) that

* A graphical user interface for debugging resource allocation policies.
* Several allocation policies for scheduling parallel jobs on clusters and
and supercomputers. The policies include aggressive backfilling, conservative
backfilling, advance reservation with conservative backfilling, selective
backfilling and agressive backfilling with multiple resource partitions.

* An implementation of the workload model by Lublin and Feitelson for modelling
the workload of clusters and supercomputers.

* A data structure to facilitate the scheduling of jobs and advance reservations.
This data structure is described as an appendix on Marcos Assuncao’s PhD thesis.

* Logging features using Java logging API.

In addition, other improvements have made GridSim more compatible with
Java 5 and 6. Some bugs have been fixed and some changes in SimJava were
required to enable a simulation to be paused and resumed.

All components developed as part of the GridSim Toolkit are released as
“open source” under the GPL license to encourage innovation and pass full
freedom to our users.

The early version of our GridSim toolkit has been used/downloaded by several
academic and commercial organizations around the world including:
University of Southern California (USA), California Institute of Technology (USA),
Argonne National Labs (USA), University of Manchester (UK), CERN,
Universidad de Santiago de Compostela (Spain), Indian Institute of Technology,
Tsinghua University (China), Sun Microsystems, IBM Research, Unisys, HP,
Northrop Grumman Information Technology, British Telecom and EMC Corp.

The contributors to the GridSim software (from early to new versions) are:
* Rajkumar Buyya, CLOUDS Lab @ The University of Melbourne.
* Manzur Murshed, GSCIT @ Monash University, Australia.
* Anthony Sulistio, CLOUDS Lab @ The University of Melbourne.
* Gokul Poduval and Chen-Khong Tham,

Since 2007, GRIDS Lab has been working on Cloud Computing along with Grid Computing. During the last 2 years, Cloud Computing related R&D activities have peaked in GRIDS Lab and we launched a new flagship
project, called Cloudbus, for Cloud Computing. In recognition of this
new thrust in Cloud Computing, we renamed GRIDS Lab as CLOUDS Lab!

2. Recently CLOUDS Lab team members have published/wrote a number of
papers related to Grid and Cloud Computing. To share a few:

Dear All:

The GRIDS Lab has recently released a detailed report on our Aneka Cloud Computing software. Brief details are enclosed below. The full report is available at:

Title: Aneka: A Software Platform for .NET-based Cloud Computing
Authors: Christian Vecchiola, Xingchen Chu, and Rajkumar Buyya
Categories: cs.DC cs.CE cs.NI cs.OS cs.PL cs.SE
Comments: 30 pages, 10 figures
Report-no: GRIDS-TR-2009-4, Grid Computing and Distributed Systems Laboratory, The University of Melbourne, Australia, May 25, 2009.
ACM-class: C.1.4, C.2.4
Abstract: Aneka is a platform for deploying Clouds developing applications on top of it. It provides a runtime environment and a set of APIs that allow developers to build .NET applications that leverage their computation on either public or private clouds. One of the key features of Aneka is the ability of supporting multiple programming models that are ways of expressing the execution logic of applications by using specific abstractions. This is accomplished by creating a customizable and extensible service oriented runtime environment represented by a collection of software containers connected together. By leveraging on these architecture advanced services including resource reservation, persistence, storage management, security, and performance monitoring have been implemented. On top of this infrastructure different programming models can be plugged to provide support for different scenarios as demonstrated by the engineering, life science, and industry applications.
