Pathways to Oracle Database migration and modernization with RAC/Exadata features

Enterprises running critical Oracle workloads face significant obstacles when migrating to the cloud, especially those relying on Real Application Clusters (RAC) and Exadata systems. These systems offer unique capabilities designed for high availability and performance, including Active-Active clustering for continuous operation, scale-out architecture for dynamic growth, built-in load balancing, transparent failover, shared cache for consistent performance, and rolling patching to minimize downtime. Exadata enhances these features with Smart Scan technology, Smart Flash Cache for improved throughput, in-memory columnar processing, Hybrid Columnar Compression to reduce storage costs, low-latency RDMA over Converged Ethernet (RoCE) networking, and elastic scalability for both Online Transaction Processing (OLTP) and analytics. AWS already offers a broad set of proven options for Oracle database migration and modernization—including Amazon RDS for Oracle, as well as replatforming to Aurora or any other purpose-built databases enabling customers to optimize for cost, agility, and innovation. However, for customers whose mission-critical applications are tightly coupled with RAC or Exadata features, achieving the same operational model in the cloud has historically required additional effort and design trade-offs. A common workaround was a hybrid approach, with applications running on AWS while databases remained outside AWS. This setup introduced significant challenges: increased latency between applications and databases that slowed performance, operational complexity from managing two platforms, dual billing, and fragmented support. These factors placed additional strain on IT teams and slowed broader digital transformation initiatives.

With the introduction of Oracle Database@AWS, these challenges are now being addressed. Customers can run the same RAC and Exadata technology directly on AWS, combining Oracle’s enterprise-grade capabilities with AWS’s scale, flexibility, and low-latency connectivity to modern, cloud-native applications on Amazon Ec2, Amazon EKS or Amazon ECS. This unified approach simplifies operations, accelerates modernization, and unlocks new opportunities for innovation at scale.

Solution overview

Oracle Database@AWS fundamentally brings Oracle Cloud Infrastructure (OCI) directly into AWS data centers through a unique architecture. With Oracle Database@AWS, you can migrate your Oracle Exadata workloads to Oracle Exadata Database Service on Dedicated Infrastructure or Oracle Autonomous Database on Dedicated Exadata Infrastructure within AWS with minimal changes, creating an unprecedented level of integration between the two platforms. You can purchase, provision, and manage your Oracle Database@AWS deployments through familiar AWS tools and interfaces such as AWS Management Console, AWS Command Line Interface (AWS CLI), or AWS APIs for applications running on AWS. The AWS APIs call the corresponding Oracle Cloud Infrastructure (OCI) APIs necessary to provision and manage the resources. The solution operates through OCI child sites that physically reside within AWS Availability Zones, where Oracle manages Exadata infrastructure while customers configure and access it through the AWS Management Console.

The ODB network provides a private isolated network for Oracle infrastructure that can be peered with Amazon Virtual Private Cloud (VPC), enabling direct connectivity between AWS applications and Oracle databases. The following diagram illustrates this architecture.

Navigating Your Oracle Database Modernization Journey on AWS with Accenture: A Five-Phase Approach to Success

In today’s rapidly evolving digital landscape, modernizing your Oracle Database infrastructure is crucial for maintaining competitive advantage. Through Accenture’s proven five-phase methodology for Oracle Exadata and RAC migrations, organizations can achieve a seamless transition while maximizing business value. Let’s explore how each phase delivers specific benefits in your modernization journey.

1. Foundation Services: Building the Bedrock of Success

Accenture begins by establishing secure application and data infrastructure foundations through automated database discovery, Oracle license optimization, and comprehensive migration planning. Leveraging Accenture myNav’s extensive cloud project experience, this phase:

• Creates modern, on-demand data foundations.
• Ensures architectural compatibility with on-premises deployments.
• Establishes optimized landing zones for mission-critical applications.
• Implements proven reference architectures for streamlined operations.

Accenture has developed a comprehensive suite of tools and accelerators specifically designed for Oracle database migrations.

• eLicense360 is a comprehensive Oracle database license management tool that enables organizations to conduct detailed assessments of their Oracle database feature and options utilization. This tool collects and analyzes both current and historical product usage data, providing detailed insights into feature utilization patterns.
• Enkitec Sizing and Provisioning Tool (eSP) is a system sizing solution that takes a data-driven approach to resource planning. Unlike traditional sizing methods that rely on general rules of thumb, eSP collects detailed metadata about system resources, including CPU, memory, disk space, IOPS, and MBPS. This fact-based tool enables organizations to quickly evaluate various what-if scenarios and alternative plans, ensuring optimal resource allocation for Oracle database deployments.
• eDB360 serves as a database analysis platform that provides a holistic view of Oracle database environments and their interactions with hosting systems and applications. This powerful tool analyzes load characteristics over time, typically spanning a month, and delivers detailed insights into top resource consumers. It performs analysis across multiple dimensions, including database configuration, memory usage, I/O patterns, and system parameters. The tool also conducts risk assessments for database availability, scalability, and performance, while providing actionable recommendations for database optimization based on good practices.
• SQLD360 is a specialized diagnostic tool designed for deep analysis of individual SQL statements within Oracle databases. It generates detailed reports at both cluster-wide and instance-specific levels, leveraging data from AWR and ASH. The tool provides comprehensive insights into execution plan details, object statistics and metadata, performance metrics, and database configuration. Through its graphical representations of performance data and trends, SQLD360 helps organizations identify and resolve SQL performance issues effectively.
• eSEC360 is a sophisticated security assessment tool specifically designed for Oracle databases that takes a multidimensional approach to security analysis. Without collecting any application data, it performs comprehensive security checks across various dimensions, including SQL injection vulnerabilities, privilege escalation risks, password security, and sensitive data exposure.

2. Database Migration: Ensuring Seamless Transition

The migration phase employs tool-driven approaches, backed by Accenture’s Enkitec Group’s expertise from over 1,000 engineered systems configurations. Key benefits include:
