Considerations For Designing an Oracle Cloud Architecture

Application & Infrastructure leaders, planning to migrate Oracle applications to Oracle Cloud Infrastructure face substantial challenges when embarking on a full or partial migration from Oracle E-Business Suite (EBS). They must create and execute a detailed plan/blueprint to successfully deploy EBS in Oracle Cloud Infrastructure.

  • They have to prioritize conducting an Oracle Cloud Infrastructure readiness assessment in order to avoid delays and escalating costs.
  • Collaboration between application, infrastructure and other functions such as business & finance is required to cement support for the desired migration path for the organization to cloud.

The following content presents, supporting services and reference Oracle cloud architecture for E-Business Suite (EBS) customers to move from on-premises to OCI.

Challenges Faced by Technical Influencers & Architects

  • Will cloud-based solutions for EBS meet all our current requirements?
  • Will the project be slow, difficult, painful, risky?
  • Will cloud-based solutions address our pain-points, e.g. capacity planning, seasonal scaling, etc.?
  • How does Oracle Cloud address certain specific challenges (like security)?

Considerations for Provisioning Oracle EBS on OCI

If you want to provision Oracle E-Business Suite on Oracle Cloud Infrastructure or migrate Oracle E-Business Suite environments from your data center to Oracle Cloud Infrastructure, you can plan a multihost, secure, high-availability topology.

This blog will cover supporting services and reference Oracle cloud architecture for E-Business Suite (EBS) customers to move from on-premises to OCI.

Fundamentals of a Successful EBS Migration

Applying Best practices and Reference Architectures Across OCI Solutions

Networking & Connectivity

Key Considerations

  • Isolation from other customers
  • Access from your HQ to E-Business Suite
    • Private network links
    • Encrypted links over public internet
    • Public internet endpoints
  • Private network connectivity
  • Isolation between application tiers
  • Monitoring, management access
  • Load balancing
  • Low network latency

The primary objectives for the networking and connectivity architecture is to provide secure, high-speed connectivity between your cloud resources and any users and/or systems that would need to access those resources. Additionally, it illustrates mechanisms by which you can design a network topology that best meets your needs, with the ability to isolate resources between bastion host, application tiers, database tiers and load balancing for security and management purposes.

Resiliency & High Availability

Key Considerations

  • Multiple active-active nodes at each application tier
  • System resilience
  • Backup strategy for non-database tiers
  • Redundancy strategy for database tier
  • Backup requirements for database tier

The primary objective for this architecture is to build resiliency, redundancy and high availability (HA) into the cloud infrastructure that is supporting E-Business Suite and its backend datasets.

Disaster Recovery

Key Considerations

Single region DR

  • Active-active components across ADs
  • Active-passive components across ADs
  • Regional subnets across ADs
  • Load-balancing
  • Storage synchronization
  • Database DR

Multi region DR

  • Application replication between regions
  • Storage replication between regions
  • Database protection between regions

The primary objectives for the following architectures are to ensure you can build disaster recovery (DR) into your deployment in case of unforeseen events which would require you to failover and still keep E-Business Suite up and running.

Security and Identity

Key Considerations

  • Ensure EBS and associated data assets are isolated
  • Protect internet-facing applications
  • Data encryption
  • Segregate operational responsibilities and restrict access to cloud services
  • Use existing and 3rd party security assets
  • Audit and monitor actions
  • Demonstrate compliance readiness

The objective of the security architecture is to enable you to maintain your security posture when running your business-critical EBS and associated applications in the Oracle Cloud.
Even though you may be reducing the overhead of building and maintaining data center infrastructure, you still need unparalleled control and transparency over what you’re running in the cloud.

Cost Management & Governance

Key Considerations

  • Set and manage cloud budgets
  • Prevent overspending
  • Ensure accurate cost tracking across departments and projects
  • Analyze which departments, services and projects are contributing to cloud usage over time
  • Get granular usage details for invoice reconciliation
  • Identify areas to optimize costs

When transitioning from a CapEx model, where many costs are fixed at the implementation of a project, to an OpEx model, where costs scale up and down with the usage of the system, customers often require cost management tools to understand, control, and communicate these cloud costs within their organization. Oracle provides tools to meet these needs and help you.

Key Considerations

  • Monitor health and capacity of cloud resources
  • Optimize E-Business Suite performance in real time
  • Detect and fix anomalies before they can impact your business
  • Identify bottlenecks and underutilized resources

You need to be able to monitor the health and capacity of cloud infrastructure resources in order to optimize performance at all times and in real time. Objectives include ensuring availability and performance in the cloud, including the ability to detect and fix anomalies before they can impact your business. Additionally, you may require the visibility to identify bottlenecks and under-utilized resources for optimize accordingly.
Chances are, you are already leveraging monitoring tools like Oracle Enterprise Manager and Oracle Management Cloud for your existing EBS deployment. Oracle Cloud Infrastructure offers infrastructure monitoring natively within the console, but it can support your existing monitoring tools.

Migration and Deployment

Key Considerations

  • Application-aware tooling so you can keep existing customizations and integrations
  • Post-migration application configuration
  • Data migration

We understand that when it comes to migrating a complex, highly customized and deeply integrated application like EBS, it’s important to do it with as little re-architecture as possible so that there’s limited downtime and the transition is completely seamless for end-users.

Expected Outcomes When You Move E-Business Suite to Oracle Cloud

Most on-premises deployments can be migrated to Oracle Cloud Infrastructure without requiring significant re-architecture, re-integration nor business process changes, and will result in a solution that is more flexible, more reliable, and delivers higher performance at a lower cost than deployments running on-premises or with other cloud providers.

Operating EBS in Oracle Cloud Infrastructure can be up to 38% less than running it on-premises. Significant savings come from eliminating upfront hardware, ongoing facilities, IT administration and support costs. Oracle also estimates that EBS costs upto 44% less on Oracle than on Amazon Web Services (AWS).

There are also significant performance benefits when you run on Oracle’s cloud.

  • OCI’s unique non-oversubscribed networks and single-tenant offerings like bare metal compute and Exadata ensure consistent performance.
  • Customers have experienced upto 30-50% performance improvements.
  • Unlike other clouds, OCI also offer service level agreements to back up performance guarantees.

Additionally, Oracle Cloud Infrastructure offers unique infrastructure capabilities, tools and support that are optimized for Oracle applications.

  • At the highest level, Oracle tests on Oracle Cloud Infrastructure and not on any other cloud.
  • EBS Cloud Manager is available only for workloads running in the Oracle Cloud to help streamline migration and ongoing lifecycle management.
  • And then there are single vendor support advantages to running your Oracle application and database on Oracle’s cloud infrastructure.
