Cloud Migration Strategies using Oracle Cloud Infrastructure (OCI)

A comprehensive guide to migrating enterprise workloads to OCI, focusing on the four key strategies: Rehost, Replatform, Refactor, and Repurchase. It details the Five Critical Phases of the migration journey, from Assessment & Planning to Optimization & Scale, and covers essential topics like cost reduction (67% average savings), security, compliance, and overcoming challenges like data transfer complexity and application dependencies.

confidence and strategic precision

2. The Enterprise Cloud Imperative
Why Migrate Now?
Digital transformation is no longer optional.
Organizations face mounting pressure to reduce
infrastructure costs, improve agility, and scale operations
efficiently.
Traditional on-premises environments struggle with
capacity planning, lengthy procurement cycles, and
escalating maintenance costs.

3. Oracle Cloud
Infrastructure: Built for
Enterprise
Security First
Isolated network virtualization and automated threat detection
protect critical workloads at every layer
High Performance
Bare metal compute and NVMe storage deliver predictable, low-
latency performance for demanding applications
Cost Efficient
Transparent pricing with no data egress fees and flexible
consumption models reduce total cost of ownership
Oracle Optimized
Native integration with Oracle databases and applications ensures
seamless migration and optimal performance

4. Four Migration Strategies
Selecting the right approach depends on your timeline, budget, technical debt, and business objectives. Each strategy
offers distinct advantages for different scenarios.
Rehost (Lift & Shift)
Move applications as-is with minimal changes. Fastest path to cloud with immediate infrastructure benefits.
Replatform
Make targeted optimizations during migration. Balance speed with cloud-native capabilities like managed
databases.
Refactor
Redesign applications for cloud architecture. Unlock full cloud potential with microservices and automation.
Repurchase
Replace legacy systems with SaaS solutions. Reduce maintenance burden and accelerate time-to-value.

5. The Migration Journey: Five Critical Phases

Assessment & Planning
Inventory applications, analyze
dependencies, calculate TCO, and
define success metrics

Proof of Concept
Validate approach with pilot workload,
test performance, and refine migration
playbooks

Architecture Design
Design landing zones, network
topology, security controls, and
disaster recovery strategy

Migration Execution
Execute wave-based migration, validate functionality, and
optimize configurations

Optimization & Scale
Monitor performance, implement automation, and
continuously improve cloud operations

6. Overcoming Common Migration Challenges
Data Transfer Complexity
Large datasets require bandwidth planning. OCI Data
Transfer Service and FastConnect provide high-
speed, secure transfer options.
Application Dependencies
Mapping interconnected systems is critical.
Automated discovery tools identify dependencies
before migration begins.
Downtime Concerns
Zero-downtime migration is achievable with proper
planning. Database replication and traffic
management enable seamless cutover.
Pro Tip: Start with non-critical workloads to
build team expertise and refine processes before
migrating mission-critical systems.

7. Cost Optimization in OCI
Right-Sizing Resources
Match compute and storage to actual workload requirements. OCI's
flexible shapes allow precise capacity alignment without over-
provisioning.
Reserved Capacity
Commit to predictable workloads with reserved instances for up to
% savings. Combine with on-demand for variable capacity needs.
Automation & Scheduling
Automatically start and stop non-production environments during off-
hours. Implement auto-scaling policies to match demand patterns.

8. Security & Compliance Framework
OCI provides enterprise-grade security controls that meet the most
stringent regulatory requirements. Built-in compliance frameworks
accelerate certification processes.
Network Isolation
Virtual Cloud Networks with
private subnets and security
lists provide defense-in-depth
protection
Identity Management
Fine-grained IAM policies
and federation with corporate
directories ensure least-
privilege access
Compliance Ready
Pre-configured templates for HIPAA, PCI-DSS, SOC , and ISO
accelerate certification
