Cloud Computing1


What Cloud Computing is NOT

• Google Mail

• What we called „online“ 10 y ago

• What we called „cluster“ 10 y ago

• Software as a Service = SaaS

Why is it so hard to define?

• Berkeley researchers:

„We couldn‘t agree on a definition …“

• Gartner definition lists criteria:

“- Uses internet technologies …“

Definition of Cloud Computing

Criteria:

1. You consume resources as services

2. Pay per use / charge back

3. Rapid elasticity

4. Self service


Public Cloud

• No upfront payment

• More than outsourcing (no fix contract)

-> somebody else owns infrastructure

• New business models emerge

• Cloud services

8/18/2011

New Business Models

Are real companies

making money

in clouds?

AWS Instance Pricing


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

-> use it for anything you like ☺

3Oracle in Public Clouds


Oracle on AWS

1.Oracle AMIs on EC2

2.Oracle VM Templates on EC2

3.DIY AMIs

8/18/2011

13


1. Oracle AMIs for AWS

http://aws.amazon.com/amis/Oracle


Oracle AMIs Limitations

• Newest Oracle SW versions only

• WebLogic / SOA Suite images US region only

• Very few images in SE-Asia region

• Some images only 32-bit

• Most images S3 based -> not persistent

8/18/2011

14


2. Oracle VM Templates on EC2

• Oracle VM and Amazon’s EC2 are both Xen based

-> AWS now offers Oracle VM based AMIs

http://aws.amazon.com/solutions/global-solution-providers/oracle/faqs/

Expectation:

More up to date images, improved availability for different regions


Oracle VM Templates on EC2

8/18/2011

15


Oracle VM Templates on EC2

• Must use AWS console -> no Oracle VM Tooling

-> No live migration

• Only High-Memory EC2 instances

• Oracle RAC not supported

• Oracle supplied AMIs only(no documented way to create your own AMI)

• US-East region only

-> tech preview, not for wider usage


3. Create your own AMI

• You can bring you license / buy new license

• 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 …

Create your own OFM AMI

Clustering in the Cloud


JNDI-Updates / Cluster Heartbeats

• There is no IP-multicast

with AWS or Rackspace

-> use WLS unicast setting instead

(it‘s default, but less scalable)

Migration


WebLogic JMS in the Cloud

• No floating IPs in the Cloud-> No whole-server migration

• Use WebLogic service migration

• Automatic service migration requires nodemanager

-> JMS alternative for applications: Opt for AWS Simple Queue Service (SQS)

8/18/2011

19


Don’t forget: Cloud Management

Scripted configuration, monitoring, multi-cloud

support, server templates?

• Oracle Enterprise Manager

• Enstratus

• RightScale

• Group of server configs that can be cloned

• Multi-cloud images


5Cloud Services

8/18/2011

20


AWS Auto Scaling

• Automatically adds or removes EC2 instances

• Based on low/high threshold

– CloudWatch metrics (EC2, RDS, SQS/SNS, RDS, …)

– own custom metrics

• Scheduled

• Fixed size / replace unhealthy instances

• SNS notification after auto scaling


Simple Queueing Service (SQS)

• Similar to JMS queues -> async & decoupling

• Zero installation, off-instance, WS-API

• 1 to one communication

• At least once semantic

• Message automatically persisted in store

-> No HA configuration necessary

8/18/2011

21


Simple Notification Service (SNS)

• Similar to JMS topics

• 1 to one many communication

• best-effort semantics

• Supports following messaging formats

– HTTP(S) using POST

– Email

– Email with JSON format

– SQS


SQS vs. WebLogic JMS Queues

8/18/2011

22


SNS/SQS or JMS?

SQS/SNS :

• Similar in function

• Zero installation, but AWS only

• Less parameters (ACK mode, compr., flow ctrl, …)

• No HA configuration necessary

• Unlimited, managed, reliable persistent store

• APIs but no JMS interface

• Free usage tier

-> alternative for applications


Storage/DB Design Alternatives

• S3 large, static objects

• EBS persistent storage (DB data file)

• RDS DB as a Service (MySQL/Oracle)

• local transient storage

• Cloud Front content distribution network

• Simple DB simple data, indexing, query

8/18/2011

23


Launch DB Wizard

for Oracle Database


AWS Relational Database Service

Features:

• Off-Instance

• Zero installation

• Resizable instance running MySQL/ Oracle DB

• Multi-Availability Zone instances with failover

• Read replicas

• Backup window and automated backups

• Minor patches and version upgrade

• No support for APEX

8/18/2011

24


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

Note: Calculate the monthly/yearly costs!

Cloud Load Balancing (LB)

• You can’t move your HW LB into the cloud

• SW based LB (HAProxy, WLS proxy plugin):

virtualization bottleneck > 100.000 pck/s

• Amazon’s ELB = LB as a Service

• ELB is off-instance, scales itself by adding IPs


AWS Elastic Load Balancer

as a Service

6conclusion


Conclusion

• OFM is ready for the cloud

• There is a learning curve involved

• Cloud services cannot replace clustering / HA

setup for JMS for Oracle products (OSB etc.)

• Oracle’s public cloud offering can be improved

• Clouds are there. You can start today!
