Manjrasoft Patent on Cloud Application Platform Goes National Phase in USA and India August 25, 2010Posted by Rajkumar Buyya in Cloud Computing, Manjrasoft News.
add a comment
Manjrasoft Pty Ltd, a developer of innovative solutions for Cloud Computing, announced the filing of its patent application with the Patent and Trademark Office in United States. Aneka technology, the foundation of the company’s patent for a “Software Platform for Grid and Cloud Computing”, enables rapid development and deployment of applications on private and public Cloud infrastructures.
“This is an important milestone for Manjrasoft, as we officially protect our unique and groundbreaking approach to the development and management of Cloud applications,” said Dr. Rajkumar Buyya Manjrasoft Founder and Chief Executive Officer (CEO). “Manjrasoft’s core technology enables software applications requiring high computation capability to run across a number of networked computers and servers, delivering increased performance and efficiency in a cost effective way. It is one of the many key technical inventions in our ‘Killer Cloud App Development Platform (CAP)’ that will enable enterprises to accelerate their application development, deployments and management in private and public clouds.”
Aneka technology primarily consists of two key components: (1) SDK (Software Development Kit) containing application programming interfaces (APIs) and tools essential for rapid development of applications. Aneka APIs supports three popular Cloud programming models: Task, Thread, and MapReduce; and (2) a Runtime Engine and Platform for managing deployment and execution of applications on private or public Clouds. The potential of Aneka as a CloudEngine has been successfully harnessed by its users and customers in three various sectors including engineering, life science, education, and business intelligence.
Manjrasoft’s patent application consists of 36 distinct claims that describe the company’s unique ability to provide a Grid/Cloud based application development platform on a network of computing nodes, comprising a configurable service container offering foundational services such as message dispatching, communication, network membership and persistence modules, and adapted to host pluggable service modules. When executed at the nodes at least one instance of the container includes a membership service module for maintaining network connectivity between the nodes, at least one instance of the container includes a scheduler service module configured to receive one or more tasks from a client and schedule the tasks on at least one of the nodes, and at least one instance of the container includes an executor service module for receiving one or more tasks from the scheduler service module, executing the tasks so received and returning at least one result to the scheduler service module. These capabilities of container are utilized to create different Cloud application programming models.
In addition, Aneka also comes with Design Explorer, a graphical environment enabling the rapid composition of data parallel applications such as parameter sweeps supporting the execution of the same program with different data sets. One of Manjrasoft’s customers, China Southern Railways, has utilized Aneka Design Explorer for composing Autodesk’s Maya-based rendering of locomotive design frames as Cloud application without any changes to Maya software. Then using Aneka runtime engine, they accelerated rendering operations on an enterprise Cloud built using in-house network of Windows desktop computers. This fast track approach demonstrates how enterprises can rapidly transform legacy applications into Cloud applications and execute them on Cloud computing infrastructure to solve problems faster with minimal investment.
Other users in life science domain have utilized Aneka to run their applications on public Cloud infrastructure such as Amazon EC2. Aneka supported dynamic leasing of computing capability (i.e., creating Virtual Machines) and managing application execution on them to meet customers Service Level Agreements (SLAs).
Additional information on how Aneka will reduce the cost of hardware requirement, accelerating development, easy deployment, improved management capability, and facilitate compliance with QoS/SLA services in private and/or public Cloud is available at the company’s website: http://www.manjrasoft.com/products.html

Melbourne, Australia. Aug 10, 2010 – The Cloudbus Project with one of its innovative technologies for Cloud Computing (Aneka) from the University of Melbourne and Manjrasoft Pty Ltd has been selected as one of the three finalists for the “2010 – Google Australia Eureka Prize for Innovation in Computer Science”.
Google Australia Eureka Prize for Innovation in Computer Science is awarded to a team or individual for an innovation in computer science that has the potential to improve the lives of many Australians. This prize is awarded as part of Google’s commitment to open innovation that improves the lives of people everywhere.
The Cloudbus Project, led by Professor Rajkumar Buyya, has developed architectural principles and software technologies such as Aneka that enable high-performance, scalable, and energy-efficient Cloud computing.
“We are privileged that our team is one of the finalists for the 2010 Australia Eureka Prize in the ‘Innovation in Computer Science’ category sponsored by Google Australia. This industry-wide recognition is further validation that our platform enables enterprises with the best-of-breed cloud application platform supporting multiple programming models currently available in the market,” said Dr. Rajkumar Buyya, CEO of Manjrasoft. “If an organization is considering adopting a cloud computing architecture for their application, Aneka Platform ensures greater level of agility over developing distributed applications over the cloud paradigms with focus on performance and scalability. Within a matter of time, the Aneka Cloud Application Development Platform can be provisioned on a public, private or a hybrid cloud allowing developers to build and deploy applications for solving problems rapidly on Cloud Computing infrastructure.”
Dr. Wolfgang Gentzsch, a former member of the US President’s Council of Advisors for Science and Technology (PCAST), stated that the Cloudbus Project features a collection of innovative and original technologies. In particular, Aneka, a middleware for developing computing Clouds, emerges among the similar solutions for its innovative and original features.
Dr. Craig A. Lee, President of the Open Grid Forum (OGF) said “Built on the widely used .NET infrastructure from Microsoft, Aneka provides a market-based approach to resource allocation and scheduling. As the world becomes more connected and interconnected electronically, such market-based approaches will eventually become the lynch pin for managing distributed computing infrastructures.” As the cloud computing concept continues to build more momentum, the concepts from Aneka will gain even more currency for economic advantage and the ability to improve lives.
Dr. Gentzsch said “Aneka constitutes a completely new approach for building heterogeneous private, public, and hybrid Clouds specifically designed with the goal of addressing the scalability needs of institutions that want to rely on Cloud Computing to shape their IT infrastructure.”

I would like to share a pointer to our recent work on Green Cloud
Computing. As you know our CLOUDS Lab at the University of Melbourne has
been working on energy-efficient resource management techniques for Data
Centers since 2007. Based on this experience and its growing importance
for Cloud computing, we have put together an article that offers vision,
identifies key architectural elements for Green Cloud Computing, and
open challenges and presents initial results (see below for details). I
hope you will find it useful.

Title: Energy-Efficient Management of Data Center Resources for Cloud
Computing: A Vision, Architectural Elements, and Open Challenges
Authors: Rajkumar Buyya, Anton Beloglazov, and Jemal Abawajy
Abstract: Cloud computing is offering utility-oriented IT services to
users worldwide. Based on a pay-as-you-go model, it enables hosting of
pervasive applications from consumer, scientific, and business domains.
However, data centers hosting Cloud applications consume huge amounts of
energy, contributing to high operational costs and carbon footprints to
the environment. Therefore, we need Green Cloud computing solutions that
can not only save energy for the environment but also reduce operational
costs. This paper presents vision, challenges, and architectural
elements for energy-efficient management of Cloud computing
environments. We focus on the development of dynamic resource
provisioning and allocation algorithms that consider the synergy between
various data center infrastructures (i.e., the hardware, power units,
cooling and software), and holistically work to boost data center energy
efficiency and performance. In particular, this paper proposes (a)
architectural principles for energy-efficient management of Clouds; (b)
energy-efficient resource allocation policies and scheduling algorithms
considering quality-of-service expectations, and devices power usage
characteristics; and (c) a novel software technology for
energy-efficient management of Clouds. We have validated our approach by
conducting a set of rigorous performance evaluation study using the
CloudSim toolkit. The results demonstrate that Cloud computing model has
immense potential as it offers significant performance gains as regards
to response time and cost saving under dynamic workload scenarios.

The CLOUDS Lab and its flagship Cloudbus Project at The University of
Melbourne, Australia along with collaborators from Pontifical Catholic
University of Rio Grande do Sul (PUCRS), Brazil is pleased to announce
the release of the new version of its Cloud simulation software, the
One year has passed since CloudSim 1.0 was released. Since then, Cloud
computing has gained more visibility, and a plenty of new projects, both
in academia and in the industry, emerged. To help developers of such
projects to evaluate new strategies and ideas before actual development,
CloudSim 2.0 offers support for model and simulation of hot topics in
Cloud Computing, including green/power-aware Cloud Computing and
federated Cloud Computing.
At the same time new features were added, major improvements in
simulation core allowed enhanced scalability and performance of
simulations and insertion and removal of simulation entities
during simulation execution. It increases considerably scenarios that
may be addressed in simulations, what we hope will contribute to a wider
adoption of the tool by the research ommunity.
These improvements were possible due to extensive support from the Cloud
Computing research community around the world, which used CloudSim,
appointed bugs, and provided us feedback on new features they would like
to have in future versions the toolkit. Community is invited to
keep contribution to CloudSim.
As in its previous version, all components developed as part of the
CloudSim Toolkit are released as “open source” under the GPL license to
encourage innovation and pass full freedom to our users.
