Cloud Migration: Get in Front of Your Options
Abacasys
Cloud computing has changed how organizations store data, run applications, manage infrastructure, and scale technology. Instead of relying entirely on physical servers and on-premises data centers, businesses can use cloud infrastructure to access computing resources over the internet.
For organizations operating legacy applications or aging infrastructure, cloud migration can provide an opportunity to improve scalability, flexibility, operational efficiency, and long-term technology management. However, successful migration requires more than simply moving servers and databases to the cloud. Businesses need a clear strategy covering applications, data, security, infrastructure, integrations, performance, and ongoing operations.
What Is the Cloud?
The cloud refers to computing resources—such as servers, storage, databases, networking, and software—that are provided through internet-accessible infrastructure.
Cloud computing allows businesses to consume technology resources without owning and maintaining all of the underlying physical infrastructure themselves. Depending on the cloud service model, organizations can use infrastructure, platforms, databases, applications, and other services on demand.
In simple terms, cloud computing allows organizations to:
Store and access data remotely
Run business applications on cloud infrastructure
Scale computing resources according to demand
Reduce the need for extensive on-premises infrastructure
Support distributed and remote teams
Improve infrastructure flexibility
Adopt managed services and automation
Cloud computing does not eliminate physical infrastructure. Instead, the infrastructure is operated by cloud providers or managed through cloud environments, depending on the deployment model.
What Is Cloud Migration?
Cloud migration is the process of moving digital assets, workloads, applications, databases, data, and supporting IT resources from one environment to another, typically from on-premises infrastructure or a legacy data center to a cloud environment.
A migration can involve different types of workloads, including:
Databases
Enterprise applications
Virtual machines
File and object storage
Business data
APIs and integrations
Development and testing environments
Analytics platforms
Supporting infrastructure
Cloud migration does not necessarily mean moving everything to the cloud. Some organizations use a hybrid cloud strategy, where certain workloads remain on-premises while others operate in the cloud.
The right approach depends on business objectives, application architecture, compliance requirements, performance needs, cost considerations, and existing technology investments.
Why Do Businesses Consider Cloud Migration?
Organizations may consider cloud migration for several reasons, including:
Scalability
Cloud infrastructure can provide flexible computing and storage resources that can be adjusted according to workload requirements.
Infrastructure Modernization
Migration can be part of a broader modernization strategy for organizations running aging infrastructure or legacy environments.
Business Agility
Cloud services can help organizations provision infrastructure and technology services more quickly than traditional infrastructure procurement processes.
Operational Efficiency
Managed cloud services can reduce some infrastructure-management responsibilities and provide automation, monitoring, backup, and other capabilities.
Business Continuity
Cloud architectures can support backup, disaster recovery, redundancy, and high-availability strategies when designed appropriately.
Global Accessibility
Cloud-hosted applications and services can support geographically distributed users when network architecture, security, and application design are properly configured.
Important Things to Consider Before Cloud Migration
Cloud migration is a major technology decision. Before moving workloads, organizations should determine why they are migrating, what they need to migrate, where workloads should run, and how the migration will be managed.
Here are some important considerations.
1. Define Why Your Business Needs Cloud Migration
The first step is to establish clear business objectives.
Ask questions such as:
What problems are we trying to solve?
Are our existing systems difficult to scale?
Are infrastructure costs increasing?
Do we need improved disaster recovery?
Are applications becoming difficult to maintain?
Do we need faster infrastructure provisioning?
Are we modernizing legacy applications?
What business outcomes should migration deliver?
A cloud migration should support measurable business and technology goals rather than becoming a technology exercise without a clear purpose.
2. Work With a Cloud Architect
A cloud architect can help establish the technical foundation for migration.
They can evaluate:
Existing infrastructure
Application architecture
Database dependencies
Security requirements
Networking
Identity and access management
Compliance requirements
Performance expectations
Disaster recovery
Cloud operating models
The goal is to select an architecture and cloud platform that fit the organization's actual requirements.
3. Choose the Right Cloud Platform
Organizations can choose from major public cloud providers as well as private and hybrid cloud environments.
The right platform should be evaluated based on factors such as:
Existing technology investments
Application compatibility
Database requirements
Security and compliance
Geographic availability
Performance
Pricing
Managed services
Integration capabilities
Skills available within the organization
The cheapest cloud option is not always the most cost-effective option. Total cost of ownership should include infrastructure, licensing, migration, networking, operations, monitoring, support, and optimization.
4. Decide What Should Be Migrated
Not every application or database needs to move to the cloud.
Perform an application and infrastructure assessment to identify:
Applications suitable for migration
Databases that require modernization
Workloads that should remain on-premises
Applications that can be retired
Systems that require redesign
Dependencies between applications and databases
This assessment helps organizations avoid moving unnecessary workloads simply for the sake of migration.
5. Choose the Right Cloud Migration Strategy
Different workloads may require different migration approaches.
Common strategies include:
Rehost
Move an application or workload to cloud infrastructure with minimal architectural changes.
Replatform
Move the workload while making selected improvements, such as adopting a managed database or cloud service.
Refactor
Redesign parts of the application to take greater advantage of cloud-native capabilities.
Repurchase
Replace an existing application with a cloud-based software service where appropriate.
Retain
Keep a workload in its existing environment when migration does not currently provide sufficient value.
Retire
Decommission applications that are no longer required.
Choosing the right strategy for each workload is often more effective than applying one migration approach across the entire organization.
6. Single Cloud or Multi-Cloud?
Organizations can operate workloads across one cloud provider or multiple cloud providers.
A single-cloud strategy can simplify architecture, skills, governance, and operations.
A multi-cloud strategy may be appropriate when organizations have specific technical, geographic, regulatory, or business requirements that benefit from using multiple providers.
However, multi-cloud environments can also introduce additional complexity around:
Security
Monitoring
Networking
Identity management
Governance
Cost management
Skills and operations
Multi-cloud should therefore be adopted for a clear business or technical reason rather than simply because multiple providers are available.
7. Establish a Performance Baseline
Before migration, establish baseline measurements for important applications and databases.
These can include:
Response time
Transaction throughput
CPU and memory utilization
Database performance
Network latency
Storage performance
Availability
Error rates
User experience
After migration, these measurements can be compared against the baseline to determine whether performance has improved, remained stable, or requires optimization.
8. Analyze Dependencies and Prioritize Migration
Applications rarely operate independently.
An application may depend on:
Databases
APIs
File systems
Authentication services
Reporting systems
Third-party applications
Network services
Other internal applications
Understanding these dependencies is critical.
Organizations should create a migration sequence that considers technical dependencies, business criticality, risk, and complexity.
Less complex workloads may be suitable for early migration pilots, while highly integrated or business-critical applications may require more extensive planning and testing.
9. Create a Detailed Migration Plan
A successful migration requires defined tasks, owners, timelines, dependencies, and acceptance criteria.
A migration plan should address:
Discovery
Assessment
Architecture
Security
Network configuration
Data migration
Application migration
Testing
User acceptance
Cutover
Rollback
Monitoring
Post-migration support
A detailed plan provides visibility into progress and helps teams identify risks before they affect the business.
10. Consider Application Retooling and Modernization
Cloud migration can also be an opportunity to improve applications rather than simply moving them unchanged.
Application modernization may involve:
Improving user interfaces
Optimizing database queries
Updating application architecture
Improving APIs
Modernizing integrations
Automating deployment
Improving monitoring
Adopting managed cloud services
For Oracle-based environments, organizations may also consider Oracle APEX as part of a broader application modernization strategy, particularly when modernizing data-centric Oracle applications while continuing to leverage existing Oracle Database investments.
The Cloud Migration Process
Once the strategy and architecture are defined, the actual migration can begin.
A typical migration process includes:
Step 1: Discovery and Assessment
Identify applications, databases, infrastructure, dependencies, data volumes, security requirements, and business priorities.
Step 2: Architecture and Planning
Design the target cloud environment and determine the appropriate migration approach for each workload.
Step 3: Migration Preparation
Prepare networks, identities, security controls, environments, backup processes, and migration tools.
Step 4: Data Migration
Transfer databases and other data to the target environment while maintaining data integrity and validating the migrated information.
Step 5: Application Migration
Move or modernize applications according to the selected migration strategy.
Step 6: Testing
Perform functional, integration, performance, security, and user-acceptance testing.
Step 7: Cutover
Move production workloads to the target environment according to the approved migration plan.
Step 8: Validation and Monitoring
Monitor applications, databases, infrastructure, security, and user experience after migration.
Post-Migration: What Happens Next?
Cloud migration does not end when workloads are successfully moved.
Post-migration operations are essential for maintaining performance, security, reliability, and cost efficiency.
Organizations should establish processes for:
Backup and recovery
Performance monitoring
Security monitoring
Patch management
Capacity planning
Cost optimization
Availability monitoring
Disaster recovery testing
Access management
Application maintenance
Cloud environments also need ongoing optimization. Resources that are not properly sized or monitored can lead to unnecessary costs.
How to Make Cloud Migration Successful
A successful cloud migration depends on more than selecting a cloud provider.
Organizations should:
Define measurable business objectives.
Assess applications and infrastructure before migration.
Map application and database dependencies.
Select the appropriate migration strategy for each workload.
Establish security and governance requirements early.
Create performance baselines.
Start with a controlled migration or pilot where appropriate.
Test applications and data thoroughly.
Prepare a rollback and disaster-recovery strategy.
Monitor and optimize the environment after migration.
Cloud Migration and Oracle Modernization
For organizations running Oracle databases and applications, cloud migration can be combined with application modernization.
Instead of simply moving an aging application to a cloud server, organizations can evaluate whether parts of the application should be modernized at the same time.
Oracle APEX can be considered for building or modernizing data-centric web applications that use Oracle Database. It provides a low-code development environment with deep Oracle Database integration, allowing teams to modernize application experiences while continuing to leverage SQL, PL/SQL, existing data, and business logic where appropriate.
This approach can be especially useful when organizations want to modernize legacy Oracle applications without automatically replacing the underlying database and business data.
