Regions and Availability DomainsOracle Cloud Infrastructure is hosted in regions and availability domains. A region is a geographic area (like the Eastern United States), and an availability domain is one or more data centers located within a region. A region is composed of several availability domains that are connected to each other by a low latency, high bandwidth network, which makes it possible to build replicated systems in multiple availability domains for both high-avail-ability and disaster recovery.

When you sign up for Oracle Cloud Infrastructure, Oracle creates a tenancy for your company, which is a secure and isolated partition within the Oracle Cloud Infrastructure where you can create, organize, and administer your cloud resources. This is not shared with any other customer.

IntroductionThe principal platform for software applications is no longer a local hard drive, it’s a web browser. Software is now frequently delivered over the internet from the cloud. In order to reduce infrastructure costs, many companies are rapidly adopting the cloud with a cloud-first strategy for new systems and the migration of existing applications to the cloud. ERP solutions like Oracle E-Business Suite (EBS) are business critical applications for most enterprises but some have already migrated EBS to the cloud and many more are planning a move.

This whitepaper provides an overview of Oracle Cloud Infrastructure and a reference architecture for deploying EBS on Oracle Cloud Infrastructure. We will explore the benefits of running Oracle E-Business suite on Oracle Cloud Infrastructure and describe various use cases.

Oracle Cloud Infrastructure OverviewOracle Cloud Infrastructure is a combination of cloud services that enables users to build and run a wide range of applications and services in a highly-available hosted environment. Oracle Cloud Infrastructure offers high-perfor-mance compute capabilities (such as physical server instances) and storage capacity in a flexible virtual network that is securely accessible from your on-premises network.

Oracle Cloud Infrastructure BenefitsInfrastructure as a Service gives IT users agility, great flexibility and cost savings. Benefits include:

• Pay as you go – only pay for the IT resources you need, when you need them

• IT resources can be deployed rapidly when needed and discarded when no longer required.

• Oracle Cloud Infrastructure (Bare Metal Cloud Service), Oracle Database, Oracle E-Business Suite, and Oracle WebLogic Server are all Oracle products or services and are built to work together.

Oracle Cloud Infrastructure ConceptsThe following Oracle Cloud Infrastructure elements are necessary for implementing and operating Oracle E-Busi-ness Suite on the Oracle cloud.

Oracle E-Business Suite On Oracle Cloud Infrastructure

A Virtual Cloud Network is a virtual version of a traditional network—including subnets, route tables, and gate-

ways—on which your server instances run. A cloud network resides within a single region but can cross multiple

availability domains. You need to set up at least one cloud network before you can launch server instances. You can

configure the cloud network with an optional Internet Gateway to handle public traffic, and an optional IPSec VPN

connection to securely extend

Oracle Cloud Infrastructure ConceptsThe following Oracle Cloud Infrastructure elements are necessary for implementing and operating Oracle E-Busi-ness Suite on the Oracle cloud.

Networking

Compute

The Oracle Cloud Infrastructure Compute Service lets you provision and manage computer servers, known as

instances.

Oracle Cloud Infrastructure offers both Bare Metal and Virtual Machine instances

• Bare Metal - A bare metal compute instance provides dedicated physical server access for the highest performance and strong isolation.

• Virtual Machine - A Virtual Machine (VM) is an independent computing environment that runs on top of physical bare metal hardware. The virtualization makes it possible to run

The Oracle Bare Metal Cloud Block Volume Service lets you dynamically provision and manage block storage

volumes. You can create, attach, connect and move volumes as needed to meet your storage and application

requirements. Once attached and connected to an instance, you can use a volume like a regular hard drive.

Volumes can also be disconnected and attached to another instance without the loss of data. Block Volume Service

volumes can be either 256 GB or 2 TB, with 2 TB volumes offering better overall performance. By default, Block

Volume Service volumes are 256 GB.

The Oracle Bare Metal Cloud Object Storage Service has a simple REST-based storage management interface that allows users to easily manage storage at scale. The elasticity of the platform enables users to start small and scale seamlessly, without experiencing any degradation in performance or service reliability.

A Virtual Cloud Network is a virtual version of a traditional network—including subnets, route tables, and gate-

ways—on which your server instances run. A cloud network resides within a single region but can cross multiple

availability domains. You need to set up at least one cloud network before you can launch server instances. You can

The elasticity of the platform enables users to start small and scale seamlessly, without experiencing any degradation in performance or service reliability.

Object Storage

The Database Service lets you quickly launch an Oracle Database System (DB System) and create one or more data-

bases on it. Users have full access to the features and operations available with Oracle Database, but Oracle owns

and manages the infrastructure. Databases are available as 1-Node, 2-Node RAC or Exadata systems.

Load Balancing

VCN



Requests submitted by users from the desktop tier are routed to the Oracle E-Business Suite application servers

provisioned on compute instances on the Oracle cloud via the Oracle Load Balancing Service. The OHS (Oracle

HTTP Server) and the Oracle WebLogic Server are provisioned on each application node. The OHS will accept the

requests from the load balancer and direct them to the Oracle WebLogic Server which executes the relevant busi-

ness logic and interfaces with the Oracle database. The various modules and functions in Oracle E-Business Suite

share a common data model. Multiple application nodes share a single database.

Load Balancing and High Availability

Incoming traffic for the EBS application provisioned on various compute instances can be managed using a load

balancer available within the virtual cloud network (VCN). In order to configure a load balancer, application nodes

must be provisioned in different availability domains. In the case of an application tier or availability domain

failure, the load balancer will redirect the requests to the other application tiers provisioned in another availability

domain.

The database tier is deployed on a compute instance or can be provisioned through database as a service (DBaaS).

Unlike other database as a service suppliers, Oracle provides command line access and full server access to DBaaS

users. Backups can be configured using the Database Backup service and placed in an object storage bucket. Oracle

Recovery Manager (RMAN) can also be used for backups of the database to an object storage bucket.

Advantages of Running Oracle E-Business Suite on Oracle Cloud Infrastructure

Technical Considerations

Oracle Cloud Infrastructure is offering 2-node RAC database and exadata database services where users can

migrate their on-premises RAC instances and exadata machines to the cloud. Oracle also provides command line

access to DBaaS instances unlike other cloud based databases. Database patches can be rolled back in DBaaS

instances.

Agility and Speed

The time required to provision Oracle E-Business Suite on Oracle Cloud Infrastructure is far less than for conven-

tional infrastructure. A traditional server provisioning involves a large number of resources and processes which

cause delay. In an agile environment frequent software updates often require hardware updates or changes too. It

can be difficult to provide this level of flexibility in a traditional data center but in the cloud it is easy.

Installation of Oracle E-Business is faster with Oracle Cloud Infrastructure than with competitive cloud environ-

ments. In our tests we found that installation times were reduced by more than 30%.

Economical Usage

In a typical on-premises datacenter, companies must pay for hardware, software licensing and physical mainte-

nance and IT staff are needed for round-the-clock monitoring. All these can be replaced by Oracle Cloud Infrastruc-

ture. IT resources are scalable. For example an environment that is used up to 8 hours a day, can be shut down after

working hours and restarted when required. This can save 16 hours of resource cost or 66% of the total. Running

Oracle E-Business Suite on Oracle Cloud Infrastructure is also much less expensive than other public clouds,

mainly because a considerable number of IOPS are included in the Oracle cloud's storage cost. This can reduce

costs by up to 80%.

Application Performance Testing

Performance testing is highly recommended prior to any change to an Oracle E-Business Suite environment. Appli-

cations are usually tested in the preliminary stages of deployment in an IT environment that is identical to the

planned production hardware. Subsequently it is difficult and expensive to test the performance of later develop-

ments because of the requirement to create a duplicate hardware environment for testing.

We found that network performance of the Oracle cloud was better than other public clouds because data transfer

was more than 20% faster and there was a 25% improvement in bandwidth. We also found that installation times

were up to 30% less on the Oracle cloud.

Hardware Immortality

Hardware upgrades are a necessary evil in an on-premises data center. As server hardware ages and new hardware

technologies are developed, IT organizations have to plan for a hardware upgrade or replacement. With Oracle

Cloud Infrastructure, a hardware upgrade is easily achieved by a single mouse click and at no cost.

Use Cases for Oracle E-Business Suite on Oracle Cloud Infrastructure

Oracle E-Business Suite customers are using Oracle Cloud Infrastructure for a variety of use cases including the following:

• Migration of existing Oracle E-Business Suite environments from on-premises and other cloud or hosting vendors

• Implementation of Oracle E-Business Suite on a 2-node RAC

• Implementing cloud based disaster recovery for Oracle E-Business Suite

• Running Oracle E-Business Suite development, test, user acceptance testing (UAT), proof of concept (POC), and training environments

• Provisional environments for migrations and upgrade testing.

• Transient environments for performance testing

Conclusion

Oracle Cloud Infrastructure is a secure IT environment that is flexible and scalable. It is adaptable to any kind of IT

environment and it is available at a competitive price.
