Abstract
Oracle E-Business Suite is a popular suite of integrated business applications for
automating enterprise-wide processes like customer relationship management,
financial management, and supply chain management. This is the first
whitepaper in a series focused on Oracle E-Business Suite on Amazon Web
Services (AWS). It provides an architectural overview for running Oracle E-
Business Suite 12.2 on AWS.
The whitepaper series is intended for customers and partners who want to learn
about the benefits and options for running Oracle E-Business Suite on AWS.
Subsequent whitepapers in this series will discuss advanced topics and outline
best practices for high availability, security, scalability, performance, migration,
disaster recovery, and management of Oracle E-Business Suite systems on AWS.

Introduction
Almost all large enterprises use Enterprise Resource Planning (ERP) systems
for managing and optimizing enterprise-wide business processes. Cloud
adoption among enterprises is growing rapidly, with many adopting a cloud-
first strategy for new projects and migrating their existing systems from on-
premises to Amazon Web Services (AWS). ERP systems like Oracle E-Business
Suite are mission critical for most enterprises and figure prominently in
considerations for planning an enterprise cloud migration.
This whitepaper provides a brief overview of Oracle E-Business Suite and a
reference architecture for deploying Oracle E-Business Suite on AWS. We also
discuss the benefits of running Oracle E-Business suite on AWS and various use
cases.
AWS Overview
AWS provides on-demand computing resources and services in the cloud, with
pay-as-you-go pricing. As of this publication, AWS serves over a million active
customers in more than 190 countries and is available in 16 Regions worldwide.
You can run a server on AWS and log in, configure, secure, and operate it just as
you would operate a server in your own data center.
Using AWS resources for your compute needs is like purchasing electricity from
a power company instead of running your own generator, and it provides many
of the same benefits:
• The capacity you get exactly matches your needs.
• You pay only for what you use.
• Economies of scale result in lower costs.
• The service is provided by a vendor who is experienced in running large-
scale compute and network systems.
Amazon Web Services Concepts
This section describes the AWS infrastructure and services that are part of the
reference architecture for running Oracle E-Business Suite on AWS.

Page 2
Regions and Availability Zones
Each Region is a separate geographic area isolated from the other Regions.
Regions provide you the ability to place resources, such as Amazon Elastic
Compute Cloud (Amazon EC2) instances, and data in multiple locations.
Resources aren't replicated across Regions unless you do so specifically.
An AWS account provides multiple Regions so that you can launch your
application in locations that meet your requirements. For example, you might
want to launch your application in Europe to be closer to your European
customers or to meet legal requirements.
Each Region has multiple, isolated locations known as Availability Zones. Each
Availability Zone runs on its own physically distinct, independent
infrastructure, and is engineered to be highly reliable. Common points of
failure, such as generators and cooling equipment, are not shared across
Availability Zones. Because Availability Zones are physically separate, even
extremely uncommon disasters such as fires, tornados or flooding would only
affect a single Availability Zone. Each Availability Zone is isolated, but the
Availability Zones in a Region are connected through low-latency links. The
following diagram illustrates the relationship between Regions and Availability
Zones.
Figure 1: Relationship between AWS Regions and Availability Zones

Page 3
The following figure shows the Regions and the number of Availability Zones in
each Region provided by an AWS account at the time of this publication. For the
most current list of Regions and Availability Zones, see

Note that you can’t describe or access additional Regions from the AWS
GovCloud (US) Region or China (Beijing) Region.

Amazon Elastic Compute Cloud
Amazon Elastic Compute Cloud (Amazon EC2) is a web service
that provides resizable compute capacity in the cloud that is billed
by the hour. You can run virtual machines (EC2 instances) ranging
in size from 1 vCPU and 1 GB memory to 128 vCPU and 2 TB
memory. You have a choice of operating systems including
Windows Server 2008/2012, Oracle Linux, Red Hat Enterprise
Linux, and SUSE Linux.
Elastic Load Balancing
Elastic Load Balancing automatically distributes incoming
application traffic across multiple Amazon EC2 instances in the
cloud. It enables you to achieve greater levels of fault tolerance in
your applications, seamlessly providing the required amount of
load balancing capacity needed to distribute application traffic.
Elastic Load Balancing can be used for load balancing web server
traffic.
Amazon Elastic Block Store
Amazon Elastic Block Store (Amazon EBS) provides persistent
block level storage volumes for use with EC2 instances in the AWS
Cloud. Each Amazon EBS volume is automatically replicated
within its Availability Zone to protect you from component failure,
offering high availability and durability. EBS volumes offer the
consistent and low-latency performance needed to run your
workloads.
Amazon Machine Image
An Amazon Machine Image (AMI) is simply a packaged-up
environment that includes all the necessary bits to set up and boot
your instance. Your AMIs are your unit of deployment. Amazon
EC2 uses Amazon EBS and Amazon S3 to provide reliable, scalable
storage of your AMIs so that we can boot them when you ask us to
do so.

Page 5
Amazon Simple Storage Service
Amazon Simple Storage Service (Amazon S3) provides developers
and IT teams with secure, durable, highly-scalable object storage.
Amazon S3 is easy to use. It provides a simple web services
interface you can use to store and retrieve any amount of data
from anywhere on the web. With Amazon S3, you pay only for the
storage you actually use. There is no minimum fee and no setup
cost.
Amazon Route 53
Amazon Route 53 is a highly available and scalable cloud Domain
Name System (DNS) web service. It is designed to give developers
and businesses an extremely reliable and cost-effective way to
route end users to Internet applications by translating names like
www.example.com into the numeric IP address.
Amazon Virtual Private Cloud
Amazon Virtual Private Cloud (Amazon VPC) lets you provision
a logically isolated section of the AWS Cloud in which you can
launch AWS resources in a virtual network that you define. You
have complete control over your virtual networking
environment, including selection of your own private IP address
range, creation of subnets, and configuration of route tables and
network gateways. You can leverage multiple layers of security,
including security groups and network access control lists, to
help control access to EC2 instances in each subnet.
Additionally, you can create a Hardware Virtual Private Network
(VPN) connection between your corporate data center and your
VPC and leverage the AWS Cloud as an extension of your
corporate data center.

Page 6
Amazon Elastic File System
Amazon Elastic File System (Amazon EFS) is a file storage
service for EC2 instances. Amazon EFS supports the NFS v4
protocol, so the applications and tools that you use today work
seamlessly with Amazon EFS. Multiple EC2 instances can access
an Amazon EFS file system at the same time, providing a
common data source for workloads and applications running on
more than one instance. With Amazon EFS, storage capacity is
elastic, growing and shrinking automatically as you add and
remove files, so your applications have the storage they need,
when they need it.
AWS Security and Compliance
The AWS Cloud security infrastructure has been architected to be one of the
most flexible and secure cloud computing environments available today.
Security on AWS is very similar to security in your on-premises data center—but
without the costs and complexities involved in protecting facilities and
hardware. AWS provides a secure global infrastructure, plus a range of features
that you can use to help secure your systems and data in the cloud. To learn
more about AWS Security, visit the AWS Security Center.1
AWS Compliance enables customers to understand the robust controls in place
at AWS to maintain security and data protection in the cloud. AWS engages with
external certifying bodies and independent auditors to provide customers with
extensive information regarding the policies, processes, and controls
established and operated by AWS. To learn more about AWS Compliance, visit
the AWS Compliance Center.2
Oracle E-Business Suite on AWS
In this section we cover the major components of Oracle E-Business Suite and
its architecture on AWS. It is important to have a good understanding of Oracle
E-Business Suite architecture and its major components to successfully deploy
and configure it on AWS.

Page 7
Oracle E-Business Suite Components
Oracle E-Business Suite has a three-tier architecture consisting of client,
application, and database (DB) tiers.
Figure 3: Oracle E-Business Suite three-tier architecture
The client tier contains the client user interface, which is provided through
HTML or Java applets in a web browser for forms-based applications.
The application tier consists of Oracle Fusion Middleware (Oracle HTTP Server
and Oracle WebLogic Server) and the concurrent processing server. The Fusion
Middleware server has HTTP, Java, and Forms services that process the
business logic and talk to the database tier. The Oracle HTTP Server (OHS)
accepts incoming HTTP requests from clients, and routes the requests to the
Oracle Web Logic Server (WLS), which hosts the business logic and other
server-side components. The HTTP services, forms services, and concurrent
processing server can be installed on multiple application tier nodes and load
balanced.
The database tier consists of an Oracle database that stores the data for Oracle
E-Business Suite. This tier has the Oracle database executables and the Oracle
database files that physically store the tables, indexes, and other database
objects in the system.

Page 8
Please refer to the Oracle E-Business Suite Concepts guide for a deeper dive on
the Oracle E-Business Suite architecture components.3
Oracle E-Business Suite Architecture on AWS
The following reference diagram illustrates how Oracle E-Business Suite can be
deployed on AWS. The application and database tiers are deployed across
multiple Availability Zones for high availability.
Figure 4: Sample Oracle E-Business Suite deployment on AWS
User requests from the client tier are routed using Amazon Route 53 DNS to the
Oracle E-Business Suite application servers deployed on EC2 instances via
Elastic Load Balancing. The OHS and the Oracle WLS are deployed on each
application tier instance. The OHS will accept the requests from Elastic Load

Page 9
Balancing and route them to the Oracle WLS. The Oracle WLS will execute the
appropriate business logic and communicate with the Oracle database.
The various modules and functions within Oracle E-Business Suite share a
common data model. There is only one Oracle database for multiple application
tier nodes.
Load Balancing and High Availability
Elastic Load Balancing is used to distribute incoming traffic across multiple
application tier instances deployed across multiple Availability Zones. You can
add and remove application tier instances from your load balancer as your
needs change, without disrupting the overall flow of information. Elastic Load
Balancing ensures that only healthy instances receive traffic by detecting
unhealthy instances and rerouting traffic across the remaining healthy
instances. If an application tier instance fails, Elastic Load Balancing
automatically reroutes the traffic to the remaining running application tier
instances. In the unlikely event of an Availability Zone failure, user traffic is
routed to the remaining application tier instances in the other Availability Zone.
Other third-party load balancers like the F5 BIG-IP are available on AWS
Marketplace and can be used as well. Please refer to My Oracle Support
document 1375686.1 for more details on using load balancers with Oracle E-
Business Suite.4
The database tier is deployed on Oracle running on two EC2 instances in
different Availability Zones. Oracle Data Guard replication (maximum
protection or maximum availability mode) is configured between the primary
database in one Availability Zone and a standby database in another Availability
Zone. In case of failure of the primary database, the standby database is
promoted as the primary and the application tier instances will connect to it.
For more details on deploying Oracle Database on AWS, see the Oracle
Database on AWS Quick Start.5
Scalability
When using AWS you can scale your application easily due to the elastic nature
of the cloud. You can scale up the Oracle E-Business Suite application tier and
database tier instances simply by changing the instance type to a larger instance
type.

Page 10
For example, you can start with an r4.large instance with 2 vCPUs and 15 GiB
RAM and scale up all the way to an x1.32xlarge instance with 128 vCPUs and
1,952 GiB RAM. After selecting a new instance type, only a restart is required for
the changes to take effect. Typically, the resizing operation is completed in a few
minutes, the EBS volumes remain attached to the instances, and no data
migration is required.
You can scale out the application tier by adding and configuring more
application tier instances when required. You can launch a new EC2 instance in
a few minutes. However, additional work is required to ensure that the
AutoConfig files are correct and the new application tier instance is correctly
configured and registered with the database. Although it might be possible to
automate the scaling out of the application tier using scripting, this requires an
additional technical investment. A simpler alternative might be to use stand by
instances as explained in the next section.
Standby Instances
To meet extra capacity requirements, additional application tier instances of
Oracle E-Business Suite can be pre-installed and configured on EC2 instances.
These standby instances can be shut down until extra capacity is required.
Charges are not incurred when EC2 instances are shut down—only EBS storage
charges are incurred. At the time of this publication, EBS General Purpose
volumes are priced at $0.10 per GB per month in the US East (Ohio) Region.
Therefore, for an EC2 instance with 120 GB hard disk drive (HDD) space the
storage charge is only $12 per month. These pre-installed standby instances
provide you the flexibility to use these instances for meeting additional capacity
needs as and when required.
Storage Options and Backup
AWS offers a complete range of cloud storage services to support both
application and archival compliance requirements. You can choose from object,
file, block, and archival services. The following table lists some of the storage
options and how they can be used when deploying Oracle E-Business Suite on
AWS.

Page 11
Storage Type Storage Characteristics Oracle E-Business Suite Use Case
Amazon EBS –
GP2 volumes
SSD-based block storage with up to
10,000 IOPS per volume
Boot volumes, operating system &
software binaries, Oracle database
archive logs
Amazon EBS –
IO1 volumes
SSD-based block storage with up to
20,000 IOPS per volume. Multiple volumes
can be striped together for higher IOPS
Storage for the database tier – ASM
disks, Oracle data files, redo logs
Amazon EFS Highly durable, NFSv4.1 compatible
filesystem
PCP out and log files, media staging
Amazon S3 Object store with 99.999999999%
durability
Backups, archives, media staging
Amazon Glacier Extremely low-cost and highly durable
storage for long-term backup and archival
Long-term backup and archival
Amazon EC2
Instance
Storage
Ephemeral or temporary storage, data
persists only for the lifetime of the instance
Swap, temporary files, reports cache,
Web Server cache
The application and database servers use EBS volumes for persistent block
storage. Amazon EBS has two types of solid-state drive (SSD)-backed volumes:
Provisioned IOPS SSD (io1) for latency-sensitive database and application
workloads and General Purpose SSD (gp2) that balances price and performance
for a wide variety of transactional workloads, including development/test
environments and boot volumes.
General purpose SSD volumes provide good balance between price and
performance and can be used for boot volumes, the Oracle E-Business Suite
application tier file system, and logs. They are designed to offer single-digit
millisecond latencies and deliver a consistent baseline performance of 3
IOPS/GB to a maximum of 10,000 IOPS per volume.
Provisioned IOPS volumes are the highest performance EBS storage option and
should be used along with Oracle Automatic Storage Management (ASM) for
storing the Oracle database data and log files. You can provision up to 20,000
IOPS per io1 volume. These volumes are designed to achieve single-digit
millisecond latencies and to deliver the provisioned IOPS 99.9% of the time.
You can use Oracle ASM to stripe the data across multiple EBS volumes for
higher IOPS and to scale the database storage.

Page 12
To maximize the performance of EBS volumes, we recommend that you use
EBS-optimized EC2 instances.6
EC2 instances have temporary SSD-based block storage called instance storage.
Instance storage persists only for the lifetime of the instance and should not be
used to store valuable, long-term data. Instance storage can be used as swap
space and for storing temporary files like the report cache or web server cache.
If you are using Oracle Linux as the operating system for the database server,
you can use the instance storage for the Oracle database Smart Flash Cache and
improve the database performance.
Parallel Concurrent Processing (PCP) allows you to distribute concurrent
managers across multiple nodes so that you can use the available capacity and
provide failover. You can use a shared file system like Amazon EFS for storing
the log and out files while implementing PCP in Oracle E-Business Suite.
Amazon S3 provides low cost, scalable, and highly durable storage and should
be leveraged for storing backups. You can use Oracle Recovery Manager
(RMAN) to back up your database and then copy the data to Amazon S3.
Alternatively, you can use the Oracle Secure Backup (OSB) Cloud Module to
back up your database. The OSB Cloud Module is fully integrated with RMAN
features and functionality and the backups are sent directly to Amazon S3 for
storage.
Benefits of Oracle E-Business Suite on AWS
In the following sections we discuss some of the key benefits of running Oracle
E-Business Suite on AWS.
Agility and Speed
Traditional deployment involves a long procurement process in which each
stage is time-intensive and requires large capital outlay and multiple approvals.
With AWS, you can provision new infrastructure and Oracle E-Business Suite
environments in minutes, compared to waiting weeks or months to procure and
deploy traditional infrastructure.

Page 13
Lower Total Cost of Ownership
In an on-premises environment, you typically pay hardware support costs,
virtualization licensing and support, data center costs, etc. You can eliminate or
reduce all of these costs by moving to AWS. You benefit from the economies of
scale and efficiencies provided by AWS and pay only for the compute, storage,
and other resources you use.
Cost Savings for Non-Production Environments
You can shut down your non-production environments when you are not using
them and save costs. For example, if you are using a development environment
for only 40 hours a week (8 hours a day, 5 days a week), you can shut down the
environment when it’s not in use. You pay only for 40 hours of Amazon EC2
compute charges instead of 168 hours (24 hours a day, 7 days a week) for an on-
premises environment running all the time; this can result in a saving of 75% for
EC2 compute charges.
Replace CapEx with OpEx
You can start an Oracle E-Business Suite implementation or project on AWS
without any upfront cost or commitment for compute, storage, or network
infrastructure.
Unlimited Environments
In an on-premises environment, you usually have a limited set of environments
to work with; provisioning additional environments takes a long time or might
not be possible at all. You do not face these restrictions when using AWS; you
can create virtually any number of new environments in minutes as required.
You can have a different environment for each major project so that each team
can work independently with the resources they need without interfering with
other teams; the teams can then converge at a common integration environment
when they are ready. You can terminate these environments when the project
finishes and stop paying for them.
Have Moore’s Law Work for You Instead of Against You
In an on-premises environment, you end up owning hardware that is
depreciating in value every year. You are locked into the price and capacity of
the hardware once it is acquired, plus you have ongoing hardware support costs.

Page 14
With AWS, you can switch your underlying instances to the faster, more
powerful next-generation AWS instance types as they become available.
Right Size Anytime
Often customers over-size environments for initial phases and are then unable
to cope with growth in later phases. With AWS, you can scale the usage up or
down at any time. You only pay for the computing capacity you use, for the
duration you use it. Instance sizes can be changed in minutes through the AWS
Management Console or the AWS Application Programming Interface (API) or
Command Line Interface (CLI).
Low-Cost Disaster Recovery
You can build extremely low-cost standby disaster recovery environments for
your existing deployments and incur costs only for the duration of the outage.
Ability to Test Application Performance
Although performance testing is recommended prior to any major change to an
Oracle E-Business Suite environment, most customers only performance test
their Oracle E-Business Suite application during the initial launch in the yet-to-
be-deployed production hardware. Later releases are usually never performance
tested due to the expense and lack of environment required for performance
testing. With AWS, you can minimize the risk of discovering performance issues
later in production. An AWS Cloud environment can be created easily and
quickly just for the duration of the performance test and only used when
needed. Again, you are charged only for the hours the environment is used.
No End of Life for Hardware or Platform
All hardware platforms have end-of-life dates, at which point the hardware is no
longer supported and you are forced to buy new hardware again. In the AWS
Cloud, you can simply upgrade the platform instances to new AWS instance
types in a single click at no cost for the upgrade.
Oracle E-Business Suite on AWS Use Cases
Oracle E-Business Suite customers are using AWS for a variety of use cases
including the following environments:
• Migration of existing Oracle E-Business Suite production environments

Page 15
• Implementation of new Oracle E-Business Suite production
environments
• Implementing disaster recovery environments
• Running Oracle E-Business Suite development, test, demonstration,
proof of concept (POC), and training environments
• Temporary environments for migrations and testing upgrades
• Temporary environments for performance testing
Conclusion
AWS can be an extremely cost-effective, secure, scalable, high-performing, and
flexible option for deploying Oracle E-Business Suite. This whitepaper outlines
some of the benefits and use cases for deploying Oracle E-Business Suite on
AWS. Subsequent whitepapers in this series will cover advanced topics and
outline best practices for high availability, security, scalability, performance,
migration, disaster recovery, and management of Oracle E-Business Suite
systems on AWS.
