Tracking System Solutions' Decision to Deploy on Virsto vDisks
Tracking System Solutions' Decision to Deploy on Virsto vDisks
by Eric Burgener
Because storage makes up such a large part of the costs of any cloud-based infrastructure, it is an obvious place to look for cost reductions. System Solutions, Inc. (SSI), a King of Prussia, Pa.-based IT solutions provider, took that advice to heart in building MySecureCloud, a hosted infrastructure solution targeted at small and medium businesses (SMBs).

Is the Cloud Broken?
Is the Cloud Broken?
by Vince Vasquez
The underlying architecture chosen by first-generation cloud providers borrows heavily from the server consolidation and virtualization era. The major difference is that the pools of compute cores are now being deployed as public-facing services, versus running the previous generation of siloed applications. Unfortunately, the resulting inefficiencies prevent full realization of the cloud promise of truly low-cost, high-performing, elastic computing. In response, Joyent has emerged as a second generation provider, rethinking fundamental cloud architecture, and ushering in the era of what they call “Smart Computing.”

Virtualization and its Advancement
Mitesh Soni - Research Engineer at iGATE Patni

Visualization has been investigated since the early days of computing. In the 1960′s, time sharing systems were pursued as an alternative to batch processing systems. Hardware architectures for providing virtualized memory systems and privileged software execution were developed. Visualization emerged as a means to more fully utilize hardware resources and facilitate time-sharing systems.

Exploring Cloud Deployment Models in IBM Workload Deployer
Dustin Amrhein - Technical Evangelist, WebSphere Emerging Technologies at IBM

One of the fundamental tenants of IBM Workload Deployer is a choice of cloud computing deployment models. Starting in v3.0, users will be able to deploy to the cloud using virtual appliances (OVA files), virtual system patterns, or virtual application patterns. The ability to provision plain virtual appliances is a way to rapidly bring your own images, as they currently exist, into the provisioning realm of the appliance. As such, I think the use cases and basis for deciding to use this deployment model are fairly evident. However, when comparing the two patterns-based approaches, virtual system patterns and virtual application patterns, the decision requires a bit more scrutiny

Autonomic Cloud Management Approaches
Dustin Amrhein - Technical Evangelist, WebSphere Emerging Technologies at IBM

The platform services segment of cloud is multi-faceted… to say the least. Lately, likely spurred on by announcements like IBM Workload Deployer and VMware Cloud Foundry, I have been thinking quite a bit about one of those facets: environment management. To be clear, I’m not talking about management tools for end-users, though that topic is worthy of many discussions. Rather, I’m talking about the autonomic management capabilities for deployed environments.

For a lot of us, that day ended Tuesday with the announcement of the IBM Workload Deployer v3.0.

Private Cloud: Elastic, or a hair ball of rubber?
Brad Vaughan - Director of Cloud Migration Services at The Armada Group

Is your private cloud elastic, or just a tightly wrapped ball of rubber? In the war between private and public cloud, people question whether you can actually unleash the elasticity from that ball of rubber bands. This post describes how to evaluate elasticity in private cloud.

A Reference Architecture For Cloud Computing
Dustin Amrhein - Technical Evangelist, WebSphere Emerging Technologies at IBM

Admittedly, when I was heads-down in code earlier in my career, I did not pay much attention to reference architectures. We had our own internal architectures that served as ‘the way and the truth’, and reference architectures for our product or solution domain were simply out of scope. Anyway, reference architectures are, by design, not detailed enough to steer someone implementing one out of hundreds of components that will fall under said architectures. So, for the most part I ignored them, even though I could hear rumblings coming from rooms full of folks arguing over revision 25 of the reference architecture for some problem domain or another.

The IBM Image Construction and Composition Tool
Dustin Amrhein - Technical Evangelist, WebSphere Emerging Technologies at IBM

In a recent post, I wrote about the importance of well-designed, well-constructed virtual images. To be clear, I am not promoting elegant virtual image design for the sake of art. Rather, if we can improve the state of the art in virtual image design and construction, there is a chance to significantly reduce image sprawl typical to many organizations today. Reducing virtual image sprawl will go a long way in reducing the amount of time and resources organizations dedicate to managing their image inventory.

Gaining access to and providing availability of this data is crucial to support your business continuity plan in the event of a disaster.

Grid, Cloud, HPC … What's the Difference?
Randy Bias - Founder at Cloudscaling

Some view grid as a pre-cursor to cloud while others view it as a different beast only tangently related. This really comes down to a particular TLA in use to describe grid: High Performance Computing or HPC. HPC and grid are commonly used interchangeably. Cloud is not HPC, although now it can certainly support some HPC workloads, Amazon's EC@ HPC Offering. No, cloud is something a bit different: High Scalability Computing or HSC.

The Future of Cloud Computing: Opportunities for European Cloud Computing Beyond 2010 PDF
Ignacio M Llorente - Full Professor & Head of Research Group at Complutense University of Madrid
Company Profile: Seventh Framework Programme

This document provides a detailed analysis of Europe’s position with respect to cloud provisioning, and how this affects in particular future research and development in this area. The report is based on a series of workshops involving experts from different areas related to cloud technologies. In more detail, the identified opportunities are: (1) Provisioning and further development of Cloud infrastructures, where in particular telecommunication companies are expected to provide offerings; (2) Provisioning and advancing cloud platforms, which the telecommunication industry might see as a business opportunity, as well as large IT companies with business in Europe and even large non-IT businesses with hardware not fully utilized. (3) Enhanced service provisioning and development of meta-services: Europe could and should develop a ‘free market for IT services’ to match those for movement of goods, services, capital, and skills. Again telecommunication industry could supplement their services as ISPs with extended cloud capabilities; (4) provision of consultancy to assist businesses to migrate to, and utilize effectively, clouds. This implies also provision of a toolset to assist in analysis and migration.

CoSL: A Coordinated Statistical Learning Approach to Measuring the Capacity of Multi-tier Websites PDF
Company Profile: Wayne State University

By Jia Rao and Cheng-Zhong Xu. Abstract: Website capacity determination is crucial to measurement-based access control, because it determines when to turn away excessive client requests to guarantee consistent service quality under overloaded conditions. Conventional capacity measurement approaches based on high-level performance metrics like response time and throughput may result in either resource over-provisioning or lack of responsiveness. It is because a website may have different capacities in terms of the maximum concurrent level when the characteristic of workload changes. Moreover, bottleneck in a multi-tier website may shift among tiers as client access pattern changes. In this paper, we present an online robust measurement approach based on statistical machine learning techniques. It uses a Bayesian network to correlate low level instrumentation data like system and user cpu time, available memory size, and I/O status that are collected at run-time to high level system states in each tier. A decision tree is induced over a group of coordinated Bayesian models in different tiers to identify the bottleneck dynamically when the system is overloaded. Experimental results demonstrate its accuracy and robustness in different traffic loads.

Virtual Infrastructure Management in Private and Hybrid Clouds PDF
Ignacio M Llorente - Full Professor & Head of Research Group at Complutense University of Madrid
Borja Sotomayor - Haizea Developer, Research Assistant & Lecturer at University of Chicago

By Borja Sotomayor, Ruben S Montero, Ignacio M Llorente, and Ian Foster. One of the many definitions of "cloud" is that of an infrastructure-as-a-service (IaaS) system, in which IT infrastructure is deployed in a provider's data center as virtual machines. With IaaS clouds' growing popularity, tools and technologies are emerging that can transform an organization's existing infrastructure into a private or hybrid cloud. OpenNebula is an open source, virtual infrastructure manager that deploys virtualized services on both a local pool of resources and external IaaS clouds. Haizea, a resource lease manager, can act as a scheduling back end for OpenNebula, providing features not found in other cloud software or virtualization-based data center management software.

Prioritized Concerns for Building Cloud Solutions PDF
Jason Carolan - Director of Cloud Solution Development at VMware, Inc
John Stanford - Cloud Solutions Architect at VMware, Inc.

The following paper details some of the areas necessary for successful building and adoption of cloud infrastructure today. In many cases, they are imperatives that seem yet to be solved. Central and obvious to cloud environments are the APIs that control the environments, the tools built to support them, and the virtualization, billing, and utility infrastructure. There are many clouds. Clouds should and can talk to other clouds either via orchestration above the cloud or (eventually) by native capability within the cloud. But there are several aspects that are not so obvious. Security, resource management, protocols, and integration between traditional IT environments and a new “cloud-like” model must integrate together.

ElasTraS: An Elastic Transactional Data Store in the Cloud PDF
Company Profile: University of California Santa Barbara

By Sudipto Das, Divyakant Agrawal, and Amr El Abbadi. Abstract: Over the last couple of years, “Cloud Computing” or “Elastic Computing” has emerged as a compelling and successful paradigm for internet scale computing. One of the major contributing factors to this success is the elasticity of resources. In spite of the elasticity provided by the infrastructure and the scalable design of the applications, the elephant (or the underlying database), which drives most of these web-based applications, is not very elastic and scalable, and hence limits scalability. In this paper, we propose ElasTraS which addresses this issue of scalability and elasticity of the data store in a cloud computing environment to leverage from the elastic nature of the underlying infrastructure, while providing scalable transactional data access. This paper aims at providing the design of a system in progress, highlighting the major design choices, analyzing the different guarantees provided by the system, and identifying several important challenges for the research community striving for computing in the cloud.

Reflective Control for an Elastic Cloud Application: An Automated Experiment Workbench PDF
Company Profile: Duke University

By Azbayar Demberel, Jeff Chase, and Shivnath Babu Abstract: This paper addresses “reflective” control for applications that use server resources from a shared cloud infrastructure opportunistically. In this approach, an external reflective controller launches application functions based on knowledge of what resources are available from the cloud, their cost, and their value to the application through time. As a driving example, we consider re-flective control for an important use of elastic computing: a virtual workbench for digital experiments, focusing on automated benchmarking. We report progress on a Workbench Automation/Intelligence Framework (Waif), and show how it can adapt to available cloud resources by planning and launching experiments in parallel. Waif is part of the ongoing Automat project – an open testbed for programmable hosting centers, built on the ORCA resource leasing platform. We designed a prototype Waif, directed at constructing server performance models by mapping server behavior within a multi-dimensional parameter space. The planner estimates the value and cost of candidate experiments based on the results of completed experiments. In this setting, we show the potential of reflective control to accelerate progress toward a benchmarking objective in a way that balances speed, accuracy, and cost.

Private Virtual Infrastructure for Cloud Computing PDF
Company Profile: University of Maryland at Baltimore

By F. John Krautheim. Abstract: Cloud computing places an organization’s sensitive data in the control of a third party, introducing a significant level of risk on the privacy and security of the data. We propose a new management and security model for cloud computing called the Private Virtual Infrastructure (PVI) that shares the responsibility of security in cloud computing between the service provider and client, decreasing the risk exposure to both. The PVI datacenter is under control of the information owner while the cloud fabric is under control of the service provider. A cloud Locator Bot pre-measures the cloud for security properties, securely provisions the datacenter in the cloud, and provides situational awareness through continuous monitoring of the cloud security. PVI and Locator Bot provide the tools that organizations require to maintain control of their information in the cloud and realize the benefits of cloud computing.

Using Proxies to Accelerate Cloud Applications PDF
Company Profile: University of Minnesota, Twin Cities

By Jon Weissman and Siddharth Ramakrishnan. Abstract: A rich cloud ecosystem is unfolding with clouds emerging to provide platforms and services of many shapes and sizes. We speculate that future network applications may wish to utilize and synthesize capabilities from multiple clouds. The problem is this may entail significant data communication that derives from the client server paradigm imposed by most clouds. To address this bottleneck, we propose a cloud proxy network that allows optimized data-centric operations to be performed at strategic network locations. We show the potential of this architecture for accelerating cloud applications.

Nebulas: Using Distributed Voluntary Resources to Build Clouds PDF
Company Profile: University of Minnesota, Twin Cities

By Abhishek Chandra and Jon Weissman. Abstract: Current cloud services are deployed on well provisioned and centrally controlled infrastructures. However, there are several classes of services for which the current cloud model may not fit well: some do not need strong performance guarantees, the pricing may be too expensive for some, and some may be constrained by the data movement costs to the cloud. To satisfy the requirements of such services, we propose the idea of using distributed voluntary resources—those donated by end-user hosts—to form nebulas: more dispersed, less managed clouds. We first discuss the requirements of cloud services and the challenges in meeting these requirements in such voluntary clouds. We then present some possible solutions to these challenges and also discuss opportunities for further improvements to make nebulas a viable cloud paradigm.

Virtual Putty: Reshaping the Physical Footprint of Virtual Machines PDF
Company Profile: University of Minnesota, Twin Cities

By Jason Sonnek and Abhishek Chandra. Abstract: Virtualization is a key technology underlying cloud computing platforms, where applications encapsulated within virtual machines are dynamically mapped onto a pool of physical servers. In this paper, we argue that cloud providers can significantly lower operational costs, and improve hosted application performance, by accounting for affinities and conflicts between co-placed virtual machines. We show how these affinities can be inferred using location-independent VM characterizations called virtual footprints, and then show how these virtual footprints can be used to reshape the physical footprint of a VM—its physical resource consumption—to achieve higher VM consolidation and application performance in a cloud environment. We also identify three general principles for minimizing a virtual machine’s physical footprint, and discuss challenges in applying these principles in practice.

Company Profile: University of Melbourne

Cloud computing focuses on delivery of reliable, secure, fault-tolerant, sustainable, and scalable infrastructures for hosting Internet-based application services. These applications have different composition, configuration, and deployment requirements. Quantifying the performance of scheduling and allocation policy on a Cloud infrastructure (hardware, software, services) for different application and service models under varying load, energy performance (power consumption, heat dissipation), and system size is an extremely challenging problem to tackle. The use of real test beds such as Amazon EC2, limits the experiments to the scale of the testbed, and makes the reproduction of results an extremely difficult undertaking, as the conditions prevailing in the Internet-based environments are beyond the control of the tester.

Hybrid Opportunistic Computing for Green Clouds
Company Profile: North Carolina State University

Abstract: On-demand, service-oriented cloud computing infrastructures continue to increase in popularity with organizations. Three observations motivate us to investigate running high-throughput, data-intensive tasks as background workloads on these cloud infrastructures. First, the rapid growth in hardware parallelism leaves more residue resources to be exploited. Second, the "incremental power usage" of piggybacking a secondary background workload onto the foreground workload to utilize those residue resources is relatively low. Third, the advances in GPGPU (General-Purpose GPU) processing enable a novel coupling of concurrent workloads. This project will explore a new computing model of offering cloud services on active nodes that are serving on-demand utility computing users. We pla ....

Content Delivery Networks (CDNs) such as Akamai and Mirror Image place web server clusters in numerous geographical locations to improve the responsiveness and locality of the content it hosts for end-users. However, their services are priced out of reach for all but the largest enterprise customers. An alternative approach to content delivery could be achieved by leveraging existing infrastructure provided by ’storage cloud’ providers, at a fraction of the cost. MetaCDN is a system that leverages several existing ’storage clouds’, creating an integrated overlay network that provides a low cost, high performance content delivery network for content creators. MetaCDN intelligently places content onto one or many storage providers based on the quality of service, coverage and budget preferences of participants.

Virtual Machines (VMs) have become capable enough to emulate full-featured physical machines in all aspects. Therefore, they have become the foundation not only for flexible data center infrastructure but also for commercial Infrastructure-as-a-Service (IaaS) solutions. However, current providers of virtual infrastructure offer simple mechanisms through which users can ask for immediate allocation of VMs. More sophisticated economic and allocation mechanisms are required so that users can plan ahead and IaaS providers can improve their revenue. This paper introduces OpenPEX, a system that allows users to provision resources ahead of time through advance reservations. OpenPEX also incorporates a bilateral negotiation protocol that allows users and providers to come to an agreement by exchanging offers and counter-offers. These functions are made available to users through a web portal and a REST-based Web service interface.

Tilera's Chip for the Cloud Computing Age
By: Ian King and Ari Levy
It's rare for a semiconductor company to promise a chip that will deliver 10 times the capacity of Intel's (INTC) best. That's the claim Silicon Valley startup Tilera is making about a chip it intends to unveil later this year. Tilera says its design, which will pack 100 microprocessors, or cores, onto a single thumbnail-size piece of silicon, will result in faster, energy-efficient computers capable of performing more tasks simultaneously. Intel's new Xeon chip has 10 cores.

The Cloud Storage Conundrum
By: Mike Vizard
When it comes to invoking cloud computing services, IT organizations are using the cloud to primarily address backup and archiving. IT organizations don’t really want to have to buy the IT infrastructure needed to house the data that is rarely accessed. But the problem is that moving data back and forth between on-premise systems and the cloud can be expensive. One of the ways that cloud computing providers make up for providing inexpensive storage resources is by marking up the cost of network bandwidth to access it.

Platform Computing Extends HPC Reach Into MapReduce
By: Derrick Harris
High-performance computing leader Platform Computing hopes to capitalize on the big data movement by spreading its wings beyond its flagship business of managing clusters and grids and into managing MapReduce environments, as well. As was the case when Platform made its foray into cloud computing in 2009, the news is significant, because Platform has a solid foundation among leading businesses, especially in the financial services industry. If large financial organizations were leery about taking their analytics efforts to the next level, Platform might help spur them along, and it might help drive even further choice for customers by driving other HPC vendors into the MapReduce and Hadoop space.
