Cloud Computing


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

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 ☺

Oracle in Public Clouds

Oracle on AWS

1.Oracle AMIs on EC2
2.Oracle VM Templates on EC2
3.DIY AMIs


12

8/18/2011

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


13

8/18/2011

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


14

8/18/2011

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

Distributed OFM Installations

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)

JMS Scalability / Availability

Q JMS_Surf3 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)


18

8/18/2011

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

Cloud Services

19

8/18/2011

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


20

8/18/2011

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


21

8/18/2011

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


22

8/18/2011

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


23

8/18/2011

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!
