Amazon EC2 Cloud Computing Cost Savings

This post is a long one and is part of an on-going series of some of the benefits we’ve identified in our experience in using Cloud Computing technologies, most notably Amazon Web Services (AWS) and different VMware products.

Overview

“The cloud”, specifically Amazon Web Services, has dramatically changed the landscape of High Performance Computing and Big Data Processing in recent years. Many things are computationally possible that would not have been a few short years ago. An organization can cost-effectively setup, launch and use a seemingly limitless amount of computing resources in minutes.

Most of the news media today is focused around using Hadoop on “Big Data”. SLTI has experience with this technology, but what happens if your task data set doesn’t fit nicely into this framework?? The writeup below is how we handled one such challenge.

Business Problem

The problem SLTI was trying to solve fits into the Business Intelligence/Data Mining area in the financial industry. The problem tested different inputs for an algorithm that is the basis for a quantitative equity trading system.
The algorithm had complex mathematical calculations and processing requirements across a large and diverse data set. by The problem required testing a wide range of input parameters across four dimensions. The algorithm was tested across sixty-two different data sets. A summary of the size of the problem is shown to the right – We basically have to analyze 9.9 billion data points to come up with something actionable.

While the program logic is specific to the financial trading ray ban sunglasses sale industry, it has many common concepts shared across different industries – engineering, legal services, etc. The question to ask is simple –Watch movie online The Transporter Refueled (2015)

How many processing tasks cheap football jerseys china have you had that you wished ran faster? Can they be split into multiple pieces and run in parallel? How can this be done cost-effectively?

Information Oakleys Outlet Technology and Software Solution

Cloud Computing has dramatically changed the cost landscape of IT Infrastructure, especially for prototype or short run projects like this one. In a cheap nba jerseys general sense, CPU cycles and RAM are cheap compared to the highly skilled labor required to improve performance by several orders of magnitude.

Our goal was simple – make the program to run a lot faster with minimal effort.

We have a large list of projects to be completed so development time is our most precious resource so we didn’t want to re-write the entire program. We kept the software changes and technology solution simple – it’s basically an 80/20 approach to setup the infrastructure and handle the code changes that still solves the problem, albeit in a less elegant fashion.

To accomplish our goal, we modified the program  to operate on a user-defined subset of the original data set. This allows the problem to be split into many small parts and spread apart across multiple servers. We can then distribute the pieces to each server to handle the processing for that subset.  

IT Infrastructure Architecture

In staying with a 80/20 simple solution first approach, we created a solution with the following pieces:

  1. Linux based application server (Amazon EC2 Amazon Machine Image (AMI), alternatively a VMware image could be created and converted to an AMI.
  2. Highly-Available, scalable, central filestore (Amazon S3)
  3. Master configuration data stored in Amazon S3

The cluster itself is comprised of sixteen cc2.8xlarge EC2 instances. Each instance has 88 Compute Units, has 2 x Intel Xeon E5-2670 processors (16 cores per instance), 60.5GB of RAM, 3370GB storage. The cluster provided 1408 Compute Units, 256 Cores and 968 GB of RAM.

The basic logic of the program goes something like this

  1. Load all required data into Amazon S3
  2. Launch the pre-configured AMI to run the program after the server launches
    • Get a specific subset of the data for the node from the central filestore
    • Update the master configuration data to notify the other nodes what data still needs to be processed before, during and after each test run.
    • Save the results to the central filestore
    • Shutdown the node after the work is completed

Cost Analysis

This is not intended to be a totally comprehensive cost comparison but rather a quick TCO comparison using some standard costs. To quickly do this, we used the AWS EC2 Cost Comparison Calculator on the bottom of this page.

SLTI’s EC2 based approach is roughly 99.5% cheaper than an in-house solution.  There are other similar examples of the ROI of an EC2 based approach for this type of workload here 

Key Takeaways

  1. Using the cloud enables a much more adaptive and scalable data processing infrastructure than in-house IT hardware.
  2. If you’re not using AWS (or something similar), you’re overpaying for IT infrastructure, especially for short run or highly variable workloads.

This post is a short overview on some of the ways we’re using advanced cloud computing technology to help our clients improve their IT agility and reduce IT expenses. We’re currently working on a few case studies that describe these concepts in more detail. To get updated with new research just sign up using the form on the right of this page.

Great New Amazon Web Services (AWS) Announcement – DynamoDB

Solid Logic has been using Amazon Web Services (AWS) since 2008 now with great results.  Today was a big day oakley sunglasses cheap for the AWS team.  They launched a new NoSQL service -DynamoDB- today around noon.  Like the other AWS offerings (EC2, S3, etc.) it is a scalable, variable cost service.  Here is the product listing page and other relevant info: http://aws.amazon.com/dynamodb/

Werner Vogels’ blog: http://www.allthingsdistributed.com/2012/01/amazon-dynamodb.html

Announcement Video:

http://www.youtube.com/watch?v=3I5PZv6vmZY

DynamoDB Overview Video:

We primarily use EC2, S3, CloudFront, and RDS (MySQL as a service).  AWS allows us to be much more agile and can reduce system complexity.  It removes SLTI from many of the day-to-day demands of setting cheap football jerseys up and managing Cheap Jerseys physical infrastructure.  By using AWS, we are able to launch an internal or client application in minutes to hours, instead of days to weeks.

There are tons of great reasons to switch many use cases over to an AWS cloud-hosted infrastructure instead of a physical one.  In the future, we will work up our spin on a cost-benefit model for AWS.  There are many good ones available on the web, most notably here – http://aws.amazon.com/economics/.  Unfortunately, many of the ones available do not include any intangible benefits.  In this case, I am defining an intangible benefit as something that is “fuzzy” to Sale put a price figure on and is subjective in nature.  Things like how it can affect focus, hiring practices, time-to-launch, required in-house skill sets, etc. would fit into this category.  cheap nfl jerseys These items can have a huge impact on the decision making process, especially for small-to-medium size firms or firms outside of concentrated technology areas with a large pool of qualified candidates.

We are excited about today’s announcement and look forward to using DynamoDB cheap nba jerseys for a product that we have coming to market in 2012.  As we begin to work with it more, we will try to document our findings and include them in the blog over here.
