Cloud Computing


“Today’s tech entrepreneurs would be out of their minds to build out their own data centers rather than

renting capacity from Amazon or another low-cost provider.”

Quote from Andy Bechtolsheim

Definition of Cloud Computing

4 Criteria 1. You consume resources as services

2. Pay per use / charge back / (free)

3. Rapid elasticity

4. Self service


“A private cloud is like having your own restaurant”


New Business Models

Are there real companies and are they making profit

in the cloud?

Are they really 100% cloud?


Netflix


Netflix

• >20 Mio subscribers / 100% AWS cloud

• $2 billion in sales last year

• 37x req/s from Jan 2010 to Jan 2011 “ …could not build new data centers fast enough… We want to use clouds – not build them.”

• SW: Tomcat, Cassandra, Hadoop, AWS Services

• HW: 1000s of AWS instances


Netflix: Chaos Monkey on AWS

Tool randomly kills production instances during business hours (!)

Will be open sourced

US Government

• Special region in Amazon Cloud

• Cloud First Policy (everything else is exception!)

• Same security as other AWS regions


Oracle Public Cloud (Intro)


State of Oracle Public Cloud

I signed up 4 times since 1y. It’s not there yet…


AWS: Sydney Region

2 Data

Centers


Amazon Web Services (Intro)


Amazon Web Services (AWS)

Infrastructure as a Service (IaaS) + Platform as a Service(PaaS)

= fully programmable

data center

-> you can automate everything…


Startup Example: Cloud Transformation for Classical Java EE Application

Static Content Dynamic Content


Amazon Web Services (AWS) Instances


AWS Instance Pricing


Pricing Options

• Spot instances with API to retrieve current/historic spot price

if bid price > spot price : it’s your instance typically 50-60% discount

what’s a good strategy for bidding?

• Reserved Instances: upfront payment (<-> cloud definition?) -> cheaper when used more than 50% of time


Pricing

• 19 Price cuts since start of AWS

• Your brain is not good with small numbers!

• Double check everything is turned off at the end


AWS: Free Micro Instance for 1 Year!

For every new customer free resources / month:

• 750 hours of Amazon EC2 Linux Micro Instance

• 10 GB of Amazon Elastic Block Storage (EBS)

• 5 GB of Amazon S3 storage

• 30 GB per of internet data transfer

• 60 days of Oracle DB instance (BYOL)

-> use it for anything you like

Amazon Machine Images (AMIs)

• Bootable OS image • Unix / Linux / Windows • 32-bit or 64-bit • Offered by Amazon, Ubuntu, Oracle, etc. • Public / private images • AMIs are per region • S3 or EBS based


Simple Storage Service

• Simple Storage Service = S3 • Cloud storage, like hashtable (name,object) • 1 byte to 5 Terabytes per object • Objects are put into “buckets” • S3 object never leaves its region -> laws, latency • SOAP / REST / BitTorrent • Not a mountable file system


Service Level Agreement for S3 Regular S3 storage

• Availability 99.99%

• Durability 99.999999999%

(Survives outage of 2 availability zones!) “of 10,000 objects stored, on average one of every 10 million years could be lost”


Reduced Redundancy S3 storage

New, cheaper option for S3 objects

• Survives outage of 1 availability zone • Durability 99.99% = 400 times of normal HD • Availability 99.99% About 2/3 the cost of regular S3 storage


S3 Pricing

EC2 Showstoppers

• Amazon crashed my SOA Suite AMI

-> they sent a sorry email… thanks anyway!

• No easy way for local EBS based AMI backup

• No easy way to copy over AMIs to other regions

• EBS volumes attachable to 1 instance only


EC2 Showstoppers

• It’s complicated to create your own AMI starting with OS ISO image.

• You can only resize stopped instances

• Dashboard is per region only

-> You can easily miss to stop resources


Oracle AMIs Limitations

• Newest Oracle SW versions only (but not WLS12c)

• WebLogic / SOA Suite images US region only

• Very few images in SE-Asia region • Some images only 32-bit • Most images still S3 based -> not

persistent


Amazon Linux Images

http://aws.amazon.com/amazon-linux-ami/






Oracle VM Templates on EC2 • Must use AWS console -> no Oracle VM Tooling -> No live migration etc • Only High-Memory EC2 instances • Oracle RAC not supported • US-East region only • You cannot import your own templates to AWS

-> “tech preview”, not for wide usage


Create your own AMI • You can bring you license / buy new license

http://www.oracle.com/us/corporate/pricing/cloud-licensing-070579.pdf

• Start with current OEL / RedHat / CentOS Linux version

• Start with EBS-based AMI • Select if 64-bit Linux (if appropriate) • Install the SW you need • After configuration -> Create a new AMI …







AWS Relational Database Service

• Oracle DB 11.2.0.2 Service: Off-Instance, no EC2 required, Zero installation

• Oracle: Standard Edition (One) / Enterprise

• CloudWatch (11 metrics: write latency, …)

• Small 1,7GB RAM, 1 ECU to 4XL 68 GB 26 ECU

• 10 GB to 1 TB data

• Resizable instances



• Read replicas (not for Oracle DB)

• Backup window and automated backups

• Minor patches and version upgrade

• No support for RAC

• OEM available as of June 2012



• Multi-Availability Zone instances

• Data Guard is not used for Multi AZ

• No SYSTEM or SYS login, restricted DBA role without ALTER SYSTEM etc.

• BYO License or License Included (from $0,11 /h)


RDS or Custom AMI? RDS is the better solution if • You need a DB quickly • You don’t have much DB or cloud knowledge • You don’t want to hire an DBA • What you care is the JDBC-URL to connect

Always calculate the monthly/yearly costs!


Oracle Clouds


The Difference (for WLS)

Do you want to install your WebLogic? (AWS=Iaas)

OR do you want to run something on WebLogic? (Oracle Java Cloud=PaaS)


Oracle Java Cloud Service • ExaLogic + JRockit Virtual Edition • EM 12c based console, CLI and REST • Extends Oracle DB Cloud Service • Get cloud credential and

deploy from IDE to “WebLogic as a Service” • Support for Oracle Virtual Assembly Builder • “Virus Scanner”: Whitelist


Oracle Java Cloud Options


Oracle Java Cloud Benefits

• OS & WLS Patching is done by Oracle

• Security and DB integration

• Zero Installation,

• No need to design for cloud

• You manage WLS instances, not servers

• Similar to RDS from Amazon

• Easy to calculate costs


Oracle Java Cloud Question to Ask I

• How many locations?

• Can you choose which location? API?

• Transfer data between locations?

• Control over WLS startup parameters?

• WebLogic Admin Console available?

• WebLogic Scripting Tool?


Oracle Java Cloud Question to Ask II

• Non-HTTP access?

• JMS supported?

• Heap > 1,5 GB?

• EJB remoting?

• For non-supported technology: is it planned?


Oracle Java Cloud Question to Ask III

• What if 3rd a party lib breaks white list?

• Can it autoscale? Based on which metrics?

• Do customers use it for 100% of their business?

• Does Oracle use it for its business?

• Why is there no hourly pricing?


Oracle Java Cloud Question to Ask IV

• When will WLS12c be supported?

• Version upgrades? Will Oracle tell you? Ask you?

• How is patching done?


Conclusion


Conclusion • AWS and Oracle Clouds complement each other • There is a learning curve! • Make sure you understand alternatives • Cloud services will make the difference • Oracle Public Cloud will be a easy and convenient starting

point Give AWS a try. You can start today!
