The Oracle and AWS Partnership

Oracle Software on EC2A partnership between Oracle and AWS that allows you to develop and deliver your applications on the Amazon Elastic Compute Cloud

Easy to use. Start developing your applications on Oracle software on Amazon EC2 in minutes

No barriers. Oracle is providing software at no charge for development of commercial applications on Amazon EC2. Pay only infrastructure charges - as little as $0.10/hour.

Pay as you go. Run production versions of leading Oracle software products and pay only for what you need, when you need it using the new “Oracle SaaS for ISVs” monthly licensing model.

Portability. Use your existing Oracle licenses for most Oracle software products in the cloud or on premise - it’s now your choice.

Products. Currently Oracle Database 9i-11gR2, TimesTen, Oracle Coherence and all Fusion Middleware. Oracle Enterprise Linux and Enterprise Manager Grid Control are fully supported on AWS. The Oracle Secure Backup Cloud Module allows you to backup your databases directly to Amazon S3.

We are currently working on support for Oracle’s Enterprise Applications and Real Application Clusters.

Oracle on AWS Use CasesProof-of-Concept/Development: Many projects involving a new technology stack begin by creating development and test environments. Prior to the cloud, these environments could take months to build out and might require executive approval for the associated CapEx. With AWS, creating a new development environment takes minutes and only costs pennies per hour.

Steady State Usage: Migrate your existing Oracle software licenses to Amazon EC2 Reserved Instances and pay even less per hour for non-stop production servers.

On-Demand Usage: Oracle’s cost-effective monthly “SaaS for ISVs” licensing model combined with the Amazon Elastic Compute Cloud allows you to easily scale up or down the number of instances as your application’s workload changes over time. This model works well for unpredictable or variable workloads.

Backup and Recovery: Use the Oracle Secure Backup Cloud Module to backup your production databases directly to Amazon S3 using your existing RMAN scripts.

Disaster Recovery: Create an in-sync Oracle Data Guard standby database on EC2.

Coming Soon!In response to requests from customers running memory and I/O-intensive applications in the cloud we are planning additions to our EC2 instance family

Aimed at database, memory caching and other high-throughput applications, these instances would offer much larger memory sizes and significantly more network I/O bandwidth.

Stay tuned over the next few weeks for an announcement!

If it took 1 millisecond to process one image, the processing time for just one pass through the data

(on a single processor) would take 30 years.

Obviously the adopted solution is much faster ……. distributed/parallel processing.


AGIS: Astrometric Global Iterative Solution

Sky scans(highest accuracy

along scan)

Scan width: 0.7°

1. Objects are matched in successive scans2. Attitude and calibrations are updated3. Objects positions etc. are solved4. Higher-order terms are solved5. More scans are added6. Whole system is iterated


AGIS Architecture

Scheduling

Very simple ..Keep all machines busy all the time!

Busy = CPU ~90%

Post jobs on whiteboard

Trains/Workers Mark Jobs – and do themMark finished – repeat until done

Previous attempt had much more general scheduling It was also ~1000 times slower.

The problem

Data centre cost� AGIS run times decrease as more processors are added. Note that the

data volume increased from 2005 to 2006 from 18 months to 5 years, theprocessor power also increased but the run time went up. This wasdramatically improved in 2007. The normalised column shows throughput perprocessor in the system (total observations/processors/hours) e.g. anindication of the real performance.

Current estimation for in-house data processing for AGIS is around 1.2 million euros

Configuring AGIS Image

Launch an m1.large instance of ami-e257b08bCheckout the source code from the svn server.Create an agis user to run the process.Set up /etc/rc.local to execute the runAgis.sh Create a generic runAgis.sh script that reads data passed to the ami during boot time (using the AWS).

Data contains JVM parameters and especificapplication parameters (Depending on the DataTrainthat will be executed at that node).


Problems Encountered along the way

Creating new images takes a long time so make sure youget it right

No ASMLib drivers for 2.6.18-53.1.13.9.1.el5xen

Oracle is very fussy about it’s IP address, hence theElastic IP

Oracle instance hostname changed to be the public DNS name

Some work still needed on the startup script to make sure the ASM boots first time

The Attitude Servers took a long time to start up (20 mins)This was due to a race condition caused by spin locks in the type of java Thread Pool we were using.


EC2 Instances


AGIS Works!


I/O Transfer from disk of up to 50 MB/sec

Oracle Performance in the Cloud


Demo

Let’s see it in action!


Conclusions

AGIS and Oracle can be run in the cloud!

The Economics work out:EC2 may work out cheaper than buying the hardware!

With the knowledge that EC2 is an option we can delay buying more machines until the middle of the mission (2014) and decide then.

Now running a new feasibility study with 60 million primary stars (1/3 of the final data)

Aim is to try and scale out to 1000 High CPU instances

Translational Medicine Defined

59

Healthcare and Life Sciences

• What’s unique about healthcare and life sciences data warehousing?– Large volume of data

• Long data (thousands of patients)

• Wide data (thousands of measurements)

– Many workers• Thousands of employees, multiple locations—all of whom need to access the same data

– Diverse skill sets• Research scientists, statisticians, medical doctors, etc

• Lots of people with advanced degrees…

60

Translational Research for

Healthcare and Life Sciences:Case Study

61

Case StudyWe were hired by a major pharmaceutical company to build a data warehouse to house pre‐clinical, clinical, and third party data and publications•Helps different types of users (scientists, clinicians, CDTLs, biostatisticians, executives) find and view results

•Allows queries of data across different stages of a study or multiple studies relating to the same subject

•Provides a view of all projects across the organization

62

Case Study• Operational and technical challenges

– Limited budget• Time, Money

– Security concerns• Proprietary corporate information

– Clinical trial results, Research focus, Experimental data• Patient data

– HIPAA, European privacy laws, etc

– Agile development process• Short development cycles, working software, collaboration with customers

– Scalability• Thousands of users, terabytes of data (eventually)

• We chose Amazon Web Services for our development, testing, and production systems.

63

Case Study

Estimated System Cost10 TB Warehouse, Total expenses over 3 years

64

Case Study

Why AWS?– Lowest cost

• Lowest storage cost

• Lowest overhead

– Highest flexibility• Add or remove instances at any time

• Start with a little storage space,scale up over time

– Easiest deployment• Fast, reliable access from our development office in MA, customer sites across US and in Europe

65

Case Study• We used these AWS tools and services:

– S3 Storage• Approximately 2 TB in use right now, scaling to 30+

– EC2 Instances• Started with Oracle AMI

– Oracle Enterprise Linux Release 5 Update 1– Oracle Database 11g Release 1 Enterprise Edition

• 6 Primary instances– Separate database and application servers– Development, Testing, and Production Systems

• Additional instances– Backup– Performance testing

Case Study• Amazon Web Services is great for data warehouses– Data warehouses are different from transactional systems

• Loading data in batches• Querying data across large tables

– AWS performance characteristics are good for data warehouses

• Good I/O operations per second, but excellent bandwidth

• Ample CPU, Memory

– Unlimited, low cost storage

68

Lessons Learned

• Optimizing Oracle on AWS:– Observations

• Minimize I/O queries

• Load large blocks of data

• Leverage CPU and memory

– Recommendations• Table and index compression

• Bitmap indexes, bitmap join indexes

• Disable logging to the redo file (NOLOGGING)

• “Extra‐Large” EC2 instances (15 GB RAM, 4 cores, 64 bit)

69

Lessons Learned

• Increasing availability on AWS– EC2 instances can die

• Actual story: We lost one day of development work when I changed a configuration parameter and rebooted an AMI instance, locking us out.

– Recommendations• Make frequent backups

– Daily backups (to another AMI instance)

– Backup to S3

• Build your own AMI– Build a machine image with your app

– Make sure you can start, stop the AMI

70

Lessons Learned

• AWS security– Remember that each EC2 instance looks like a public host on the internet

– Recommendations• Use IP filtering (“AWS security groups”) to restrict access during development

• Get your organizations security staff involved early

• Start with a secure AMI

• Treat the EC2 instance like a Windows/Linux server on the public internet
