For instance:
- For enterprises where speed, cost and risk are prioritized, rehost or list and shift will be the ideal strategy
- Also, if you don’t want to modify the mission-critical application and still want to enjoy the benefits of cloud migration, lift and shift could be the right choice
- Again, organizations that want moderate improvements should go for replatform
- In case your legacy application is outdated and not performing well, consider retiring them for smoother operations
- If you can afford higher upfront investments in terms of both time and financial resources – also aim to fully utilize the power of could in the long-term, refactor will provide most cloud-native advantages and scalability.
3. Selecting a Cloud Provider
Consider the following factors when selecting a cloud provider:
- Costs
- Existing relationships with cloud providers
- Security options
- Agency-specific requirements
4. Transferring and Restoring Backup
Migrating backups to the cloud requires careful planning, especially for large datasets. Consider options that meet project objectives and timelines and ensure efficient transfer over WAN connections.
5. Establishing User Connectivity
Ensure users can connect to the application while maintaining the organization’s security requirements.
Key factors:
- Available bandwidth
- Number of users
- Security pathways to connect to the cloud provider
6. Testing the New System
Define a test plan before migration to ensure the application works as expected. Testing should cover both common and uncommon user functions
Steps for testing:
- Perform tests on the original system before migration
- Conduct tests on the new system post-migration
- Compare results to verify functionality
7. Disaster Recovery and Business Continuity
- Cloud migration offers new disaster recovery and business continuity options
- Incorporate appropriate recovery options to ensure mission success and system viability
8. Plan for Post-Migration Support
- Create a post-migration support plan to tackle any issues that might surface
- Monitor system performance closely
- Ensure users are well-trained and have a rollback strategy ready for critical failures
How to Reduce Risk During Cloud Migration?
If done properly, cloud migration of legacy systems comes with a wealth of benefits. To achieve an efficient data center, make sure you avoid the potential risks in each stage of the journey. Here are the key risks involved:
Underestimating Complexity
Complex dependencies, custom setups, and outdated tech aren’t always visible at first glance. These factors can complicate and prolong migration efforts significantly.
Data Integrity Issues
Mishandling or incorrect mapping can lead to data corruption, loss, or inconsistencies. It protects your operations and upholds trust in your systems. Without it, vulnerabilities can arise and can impact reliability and confidence.
Performance Issues in the Cloud
Moving on-premises applications to the cloud isn’t always smooth. Architectural differences can degrade performance, affect customer satisfaction, and drive-up operational costs. The result? Lost revenue opportunities. This is why it’s important to get help from experts who have done it first-hand.
Misaligned Goals and Expectations
Without clear objectives, businesses risk ending up with infrastructure that falls short of their needs. Misaligned goals often result in inefficiencies and poor performance. This misalignment can hinder your ability to fully realize the anticipated benefits of cloud adoption.
Lack of Cloud Expertise
It demands a thorough grasp of both legacy systems and cloud environments. Teams lacking cloud expertise may struggle with application optimization, security, and performance. This can result in a migration that falls short of expectations.
Inadequate Testing
Legacy applications can act unpredictably in the cloud. Insufficient testing can degrade performance, cause system crashes, and expose security vulnerabilities. Post-migration, these issues may disrupt operations.
Vendor Lock-In
Relying solely on one cloud provider can restrict your future options. Vendor lock-in complicates migration and limits access to top solutions. Over time, this dependence can hinder growth and flexibility. Costs may also rise if pricing changes unexpectedly.
Budget Overruns and Hidden Costs
Cloud migration projects frequently encounter unexpected expenses. These costs often stem from underestimating the project’s scope, facing technical hurdles, or experiencing delays. Such budget overruns can drain financial resources and diminish the migration’s ROI – risking the project entirely.
Compliance and Regulatory Risks
Sensitive data requires tight compliance with privacy legislation and industry regulations. If not resolved, these issues can lead to hefty penalties and lawsuits.
