Cloud migration is a fairly complicated process, with multiple considerations and moving parts. Organizations that approach cloud migration without proper preparation often face unexpected challenges, cost overruns, and limited benefits from their investment. According to the Velostrata and Dimensional Research report in 2017, 62% of businesses claim that adopting a cloud infrastructure was more difficult than they had anticipated.
So, if you’re currently considering migrating your organization’s data and applications to a cloud-based infrastructure, here’s your complete roadmap to successfully migrate your business to the cloud.
1. Develop a Comprehensive Cloud Migration Strategy
Your cloud migration journey begins with establishing a clear, well-defined strategy that outlines your objectives, timelines, and success metrics. This foundational step determines the scope of your migration and identifies key stakeholders across your organization.
Understanding the six fundamental approaches to cloud migration is also essential, such as rehosting (lift-and-shift), replatforming, refactoring, repurchasing, retaining existing systems, and retiring obsolete applications. These strategies determine the nature of migration, whether deep or shallow.
Deep cloud migration involves transferring your entire IT infrastructure to cloud environments, maximizing cloud-native benefits like scalability and cost optimization. Shallow migration takes a hybrid approach, moving few workloads while maintaining critical systems on-premise, such as hosting applications in the cloud while keeping sensitive databases locally.
Your migration strategy must also define your preferred cloud deployment model: public, private, hybrid, or multi-cloud. Each model presents unique advantages and challenges that should align with your business requirements, compliance needs, and budget constraints.
You can also involve a cloud service partner, like Transnet Cloud, during this phase to help evaluate service compatibility and identify optimal migration pathways.
2. Select the Right Cloud Service Provider
Choosing your cloud service provider (CSP) is a critical decision that impacts every aspect of your migration and long-term cloud operations. The cloud services market offers numerous providers, each with distinct strengths, pricing models, and service portfolios. Consider these key evaluation criteria when making a choice:
- Pricing structure and cost transparency
- Security protocols and compliance certifications
- Service availability and performance guarantees
- Technical support quality and responsiveness
- Integration capabilities with existing systems
Leading cloud providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform each offer unique advantages. AWS provides the most comprehensive service catalog, Azure excels in hybrid cloud scenarios and Microsoft integration, while Google Cloud Platform leads in data analytics and machine learning capabilities.
Consider conducting proof-of-concept projects with shortlisted providers to evaluate real-world performance and compatibility with your specific requirements.
3. Calculate Total Cost of Ownership (TCO)
Accurate cost estimation is crucial for cloud migration success and ongoing budget management. Your total cost of ownership extends beyond basic infrastructure costs to include migration expenses, training, and operational changes.
Cost Components to Consider:
- Initial migration and data transfer costs
- Monthly cloud service subscriptions
- Compliance and regulatory requirements
- Staff training and certification programs
- Potential licensing changes or renewals
- Ongoing management and monitoring tools
Most cloud providers offer cost calculators and assessment tools to help estimate expenses. However, consider engaging cloud economics specialists from Transnet Cloud for complex migrations involving multiple workloads and services.
Also, include the learning curve associated with cloud-native operations. Your team will need time and training to optimize cloud resource utilization and avoid unnecessary costs like over-provisioning or idle resources.
4. Prepare Your Organization for Change
Cloud migration represents a significant organizational transformation that affects technology, processes, and people. Successful migration requires cultural adaptation and skill development across your organization. It is advisable to change your management strategies:
- Conduct comprehensive cloud readiness assessments
- Implement cloud training programs for technical teams
- Organize workshops to demonstrate cloud capabilities
- Encourage cloud certifications for key personnel
- Establish cloud governance policies and procedures
Application modernization often accompanies cloud migration. This may involve refactoring legacy applications, implementing cloud-native architectures, or adopting containerization technologies. Testing and validation become critical components of this transformation process.
Create feedback mechanisms to address concerns and resistance to change. Early adoption champions can help drive organizational buy-in and share success stories.
5. Build a Detailed Migration Roadmap
A well-structured migration timeline ensures systematic progress while minimizing business disruption. Your roadmap should prioritize workloads based on business criticality, technical complexity, and interdependencies.
Migration Sequencing Options:
- Phased approach: Gradual migration of applications and data
- Big bang approach: Complete migration during a planned maintenance window
- Parallel approach: Running systems simultaneously during transition
Your migration roadmap should specify exactly when, what, and how each component will transition to the cloud. Prioritizing business-critical applications often provides faster return on investment and demonstrates cloud value to stakeholders.
Include comprehensive backup procedures, data synchronization protocols, and rollback plans in your roadmap. Many cloud providers offer specialized migration services—such as AWS Database Migration Service—that can significantly simplify and accelerate the process.
Testing phases should also be integrated throughout your timeline to validate functionality, performance, and security at each migration milestone.
6. Establish a Cloud Migration Center of Excellence
Form a dedicated cloud migration team combining IT expertise with business knowledge. This specialized team focuses exclusively on planning, executing, and optimizing your migration process. Your team should include:
- Cloud architects and engineers
- Security specialists
- Project managers
- Business analysts
- Change management coordinators
Provide your migration team with appropriate resources, including cloud training, migration tools, and direct access to your chosen CSP’s support resources. Many cloud providers offer technical account managers and solution architects to assist during migration.
Your center of excellence should establish cloud governance frameworks, security policies, and operational procedures that will guide both migration and post-migration management.
7. Implement Effective Communication Strategies
Clear, consistent communication ensures all stakeholders understand migration objectives, timelines, and their specific responsibilities. Develop a comprehensive communication plan alongside your technical migration strategy. Your communication elements could include:
- Regular progress updates for executives and department heads
- Detailed technical documentation for IT teams
- User training materials and guides
- FAQ resources addressing common concerns
- Feedback channels for reporting issues
Create visual migration dashboards that track progress against key milestones. This transparency helps maintain organizational support and identifies potential issues before they impact timelines. Also, document lessons learned throughout the process to improve future migrations and share knowledge across your organization.
8. Plan for Post-Migration Optimization
Migration completion marks the beginning of cloud optimization and management. Without proper post-migration planning, your organization may experience cost overruns and suboptimal performance that diminish cloud benefits. Consider the following post-migration focus areas:
- Cloud cost optimization and resource right-sizing
- Performance monitoring and tuning
- Security policy implementation and compliance
- Backup and disaster recovery procedures
- Ongoing staff training and skill development
Implement cloud financial management practices to monitor spending and optimize resource utilization. Set up automated policies for resource scaling and cost alerts to prevent budget surprises.
Regular optimization reviews with your CSP can identify opportunities to leverage new services, improve performance, and reduce costs. Many providers offer managed services that can simplify ongoing cloud operations.
Additional Cloud Migration Considerations
Security and Compliance: Implement robust access management systems and encryption protocols to protect applications and data in cloud environments. Understand the shared responsibility model with your chosen provider to ensure comprehensive security coverage.
Performance Monitoring: Establish key performance indicators (KPIs) and monitoring systems to track cloud resource performance against business objectives. This data helps justify migration investments and identifies optimization opportunities.
Disaster Recovery: Design and test disaster recovery procedures specific to your cloud environment. Cloud platforms offer enhanced backup and recovery capabilities that can significantly improve your organization’s resilience.
