Overview:
Cloud migration in 2027 requires businesses to choose the right workloads, balance costs, and protect critical operations.
Common challenges include rising cloud expenses, data dependencies, security gaps, and disruptions during migration.
Clear success measures, tested recovery plans, and regular performance reviews help businesses achieve lasting value from cloud migration.
Moving systems to the cloud is not the hard part anymore. Protecting business continuity while changing the infrastructure behind daily operations is. Flexera's 2026 State of the Cloud Report found that organizations estimated 29% of their infrastructure and platform cloud spending was wasted. That marks the first rise in five years. The report points to growing complexity from AI workloads and newer cloud services.
Businesses planning a migration should treat this as a signal. Forecast AI-related costs early. Set spending controls before workloads move, not after.
A well-planned migration reduces infrastructure constraints and supports new capabilities. Financial benefits often take time to show up, though. Migration changes management responsibilities. It does not remove them.
Choosing the Right Migration Strategy
Each case requires a different strategy. Rehosting involves moving an already existing application to the cloud with minimal changes. This approach is known as 'lift and shift.' Such a solution is useful for working systems that operate using obsolete hardware. Migrating the application alone will not reduce costs or increase performance.
Replatforming involves some minor adjustments during the migration process. The company could migrate its databases to a managed service while keeping most of the application untouched. Refactoring requires much work. This strategy involves redesigning the application.
Such an option would be justified if improved performance and/or maintainability or future growth were needed. Discontinuing involves eliminating old and unnecessary applications that do not provide any value to the business. Each approach depends on the particular situation.
Common Challenges Businesses Still Face
Costs may quickly become unmanageable if you do not control them closely. The unused services will continue to run. You spend on more computing resources than needed. You accumulate data transmission charges. The combination of old and new systems while performing the migration is another cause of growing costs. Reviews allow people to discover waste and manage costs.
Data dependencies complicate the migration process even more. For example, you have a customer database that performs many functions, including sales, support, order management, and report generation. Without proper analysis of such dependencies, migration could affect several processes at once. You should discover and analyze dependencies before migration to avoid any trouble.
The issue of security deserves your attention as well. The old access rights do not fit the new environment. You should verify access rights, encrypt sensitive data, and check backup procedures.
Best Practices That Actually Work
Start with a pilot phase with a less risky project to identify possible problems. Objectives should be clearly set with respect to acceptable downtime, data accuracy, performance, and recovery. A single migration manager should manage the project in terms of time, budget, risk management, and coordination of technology and business people.
Keep monitoring your cloud costs throughout the entire process. Monthly monitoring will reveal any unexpected expenses. Any unexpected expenses need to be alerted and someone needs to review them.

A Practical Decision Framework
Measuring Migration Success
The accomplishment of the migration does not necessarily imply its success. Evaluate the outcome of the migration based on the established criteria. Here are the five criteria to take into account: the ratio between the budget and the expenditure, application availability, the response time, the recovery time in case of failure, and employee productivity. Match the criterion with its value before the migration.
Analyze the metrics mentioned above monthly during the three months after the completion of the migration process. Explore the reasons behind the overspending and long response time and redistribute the available resources. Share the information with your team members so that everyone could see the results.

Final Thought
To make sure that your cloud migration goes successfully, you should have well-defined reasons for each step, an acceptable level of risk, and evaluation procedures. Protect those things in your business, without which you would be ruined. Carefully control your costs and test your plan B ahead of time. Only then will you be able to upgrade and make sure that nothing unexpected occurs. Speed does not matter here. Efficiency does.

FAQs
1. What is the difference between rehosting and replatforming?
Rehosting moves an application to the cloud with almost no changes. Replatforming makes small improvements during the move, such as switching to a managed database service, while keeping most of the application the same.
2. Why do cloud costs often rise after migration instead of falling?
Costs rise when unused services keep running, computing resources are larger than needed, or old and new systems operate together during the transition. Clear budgets and regular cost reviews help catch this early.
3. How is a rollback plan different from a disaster recovery plan?
A rollback plan reverses one failed application move. A disaster recovery plan covers how the whole business recovers from a major outage, including acceptable data loss and how fast services must return.
4. How soon should businesses measure migration success?
Reviews should start right after migration and continue monthly for the first three months, comparing spending, availability, response time, recovery time, and productivity against pre-migration figures.
5. Why do some applications stay on existing infrastructure instead of moving to the cloud?
When migration costs outweigh the benefit, keeping an application on its current setup makes more sense. Not every system needs to move for the business to gain value from the cloud.
