The Cloud

The Cloud is a set of services and

technologies that delivers real-time and on-demand computing resources

Software as a Service (SaaS) delivers pre-configured applications, usually through web

browsers

Infrastructure as a Service (IaaS) deliverscomplete server and network infrastructureon-demand hosted by a cloud provider

Platform as a Service (PaaS) delivers asolution stack (like LAMP) tailored to certainapplication types


3/30

Cloud Providers

Amazon AWS

Most popular and largest provider PaaS and IaaS solutions Large number of Cloud datacenters and

services Rackspace

Offers Windows and Linux Cloud servers Hybrid cloud model allows for half cloud,

half physical infrastructures

Microsoft

Windows Azure Runs Windows andLinux

Has IaaS and PaaS offerings Many other providers, including leading

commodity hardware manufacturers


4/30

Benefits to the Cloud

Costs No capital expenses, pay as you go

Scale on demand

Ease of maintenance, simplified infrastructure

Agility in responding to business needs Instances dedicated to UAT, new projects,

patch/upgrade testing created on demand Scripted deployments for fast server

creation and application installation New projects can have server assets in

place in hours versus weeks or months

Audit and regulatory requirements

Downsides to the Cloud Downtime Risks

Amazon AWS major outages April 2011 - 36 hours, US East August 2011 1 hour, US East June 2012 6 hours, 14 hours, US

East

Major cloud providers have SSAE16/SAS70reports, and are PCI-DSS Level 1 certified

Application expertise

High throughput, high performance cloudofferings are not as fast as traditionalhardware

Cloud server configurations are limited

Overall Cost vs Performance

AWS reserved instances make current Cloudcost/performance exceed hardware in somecases

Database performance per dollar spent ishigher on hardware Storage I/O is the leading factor

Cost vs performance plays to the Cloudsexisting strengths horizontally scaledapplications

RDBMS and other applications that benefitfrom vertical scale are less cost efficientcurrently in the cloud

Hybrid OTM DR with the Cloud


27/30

OTM Benefits and Usage

Development and Test Systems Agility of

the cloud without the need for highperformance Lower costs if reserved AWS servers are

used and if servers are powered off off-

hours

Upgrade testing Test new OTM versions

without impacting existing development cycles Disaster Recovery

Running versus non-running billing forAWS

DR system is potentially lower throughput Replicate databases, do not launch app

servers until needed Training Train users on cloud systems toavoid impacting development cycles


28/30

OTM Benefits and Usage Cont

High Performance Production Cloudperformance still lags behind hardware

Support Cloud technology is still new, bugs

and support difficulties may exist Amazon and Oracle joint support

agreement for EC2 applications Amazon RDS and Oracle Future licensing

Troubleshooting Opacity Opacity toupstream issues can make troubleshootingOTM performance more difficult

Vendor certification/POC Validate new

OTM related products with lower startup costs


29/30

Future Cloud Growth

AWS prices are reduced 2-3 times per year,

on average Amazon High I/O instance is the benchmark

for near-future Cloud performance

Google has joined the Cloud market with

Google Cloud Platform

Growth trends through 2010 show a fasterdecrease in Cloud resource prices thancorresponding hardware, excluding storage

Future generations of enterprise applicationswill be tailored to cloud deployments, bothpublic and private
