Workload Partitioning across Public/Private Clouds
Ilyas Iyoob - Sr. Research Scientist, and Director of Advanced Analytics at Gravitant

This presentation gives a methodology for optimally partitioning an application workload across Public/Private clouds. The key drivers are demand variability and cost predictability.


The Cloud in HP’s Cloud (Part 2): HP Discover, the Enterprise and AWS Cloud
Ofir Nachmani - Chief Evangelist at Newvem Insights Ltd.

Last month I attended HP Discover (disclosure: my participation was funded by Ivy World). The IT war already started however HP stands still not taking initiatives and real risks as true leaders should take. At the three-day conference I learned why some companies don’t last and why this IT giant is at a great risk of losing in this new era IT battle. This is a story of a lasting company that might have already lost.

This article looks at the issues that arise because of inefficiencies in large datacenters


SaaS and Cloud Computing: a lecture by Phil Waineright
Ofir Nachmani - Founder and Auther at I Am OnDemand.com
Phil Wainewright - Blogger at ZDNet & CEO at Procullux Ventures

More than a week ago I attended SafeNet and IGT event discussing monetization of cloud applications. In this event I had the pleasure of meeting and hearing Mr. Phil Waineright who lectured on the industry of Cloud Computing, including specifics for ISV as SaaS vendors. Since 1998, Phil Wainewright has been a thought leader in cloud computing as a blogger, analyst and consultant. The presentation started with a technical PowerPoint problem, so it was a bit amusing as he started the lecture in a spontaneous manner.


Cloud Performance and Availability from the Global Perspective
Paul Burns - President at Neovise LLC

A discussion on monitoring cloud performance and availability from the global perspective.


Benchmarking of EC2's new Cluster Compute Instance Type
Jason Read - Founder at CloudHarmony.com

In July 2010 Amazon released a new EC2 instance type, the Cluster Compute Instance or cc.4xlarge. This new instance type is primarily targeted for HPC workloads. The major distinguishing features between the cc.4large and other EC2 instances types are Hardware-Assisted Virtualization and 10 Gbps non-blocking network. This article summarizes 100 different CPU, IO and application benchmarks we ran on the cc.4xlarge and how the results compare to other EC2 instance types.


Shopping the Cloud: Performance Benchmarks
Geva Perry - Founder & Blogger at Thinking Out Cloud

As cloud computing matures - meaning it is being used by increasingly larger companies for mission critical applications - companies are shopping around for cloud providers with requirements that are more sophisticated than merely price and ease-of-use. One of these criteria is performance.


Cloud Server Benchmarking: Encoding & Encryption
Jason Read - Founder at CloudHarmony.com

It is often difficult to compare application performance between different IaaS services. Varied performance terminology, underlying hardware, and multi-tenancy factors add complexity to problem. In this post we summarize the results of benchmarking 150 cloud servers in 20 public clouds. In it, we focus on 7 benchmarks related to encoding and encryption application performance and attempt to provide a comparable performance metric for each cloud server benchmarked.


Disk IO Benchmarking in the Cloud
Jason Read - Founder at CloudHarmony.com

Storage IO performance varies significantly between different IaaS services. Factors that affect performance include storage type (local or networked), disk type (SATA, SAS, SSD), configuration (Raid), and multi-tenancy (shared IO). In this post we summarize the results of benchmarking 150 cloud servers in 20 public clouds. Using a physical server with SAS Raid 1+0 disks as a baseline, and the results of 7 IO focused benchmarks, we attempt to provide a comparable storage performance metric for each cloud server benchmarked.


What is an ECU? CPU Benchmarking in the Cloud
Jason Read - Founder at CloudHarmony.com

It is often difficult to compare IaaS services because the terminology used to describe compute resources is very different. For CPU resources, EC2 uses ECUs, vCloud use vCPUs, KVM uses MHz, etc. In this post we summarize the results of benchmarking 150 cloud servers in 20 public clouds. Then, using EC2's ECU as a baseline, and results of 19 CPU focused benchmarks, we attempt to provide a comparable CPU performance metric for each cloud server benchmarked.


Gomez: Which Cloud Service Is the Fastest?
By: Stuart J. Johnston
With all the urgency and excitement revolving around cloud computing these days, it's not surprising that differentiating among the various services becomes important -- and one of the top criteria is sure to be performance. In fact, newly-released "last mile" rankings for December show bitter rivals Microsoft (NASDAQ: MSFT) and Google (NASDAQ: GOOG) running neck and neck, according to Compuware's (NASDAQ: CPWR) Gomez cloud performance tracking service.
