Top Cloud Migration Services Companies

What Is Cloud Migration and Why It Matters in 2026

Cloud migration refers to the process of moving apps, data, workflows, and IT infrastructure from on-premise environments or legacy systems to cloud platforms like public, private, or hybrid cloud environments.

Cloud migration will become an essential task for US enterprises in 2026, as most of the businesses are being forced to upgrade their legacy systems. Cloud migration services for companies help them to decrease infrastructure costs while providing capacity for growth and improving their cybersecurity and AI analytics capabilities. The need for multi-cloud strategies, compliance, and remote workforce enablement is also increasing.

With such a rising need, successful cloud migration is not just a technical lift-and-shift project. US businesses consider it a transformation initiative that requires careful planning on the structure, risk management, governance, and choosing the right vendor.

Main Types of Cloud Migration Solutions

US companies have different needs for modernization. The cloud migration solutions also vary depending on legacy system complexity. The most common approaches are:

• Rehosting (Lift and Shift): You move apps to the cloud with very few code changes, which leads to accessing only limited cloud-native capabilities. This solution is suitable for quick transitions.
• Replatforming: You perform some optimizations, such as database upgrades or managed services adoption, without fundamentally changing the app’s architecture. This strategy assists in balancing speed and cloud efficiency.
• Refactoring (Re-architecting): You re-architect the apps to use all cloud native services, microservices architecture, containers, or serverless computing. Refactoring improves application performance while enhancing system capacity to handle increased workload.
• Hybrid or Multi-Cloud Migration: You distribute workload between on-premises and multiple cloud platforms. It enhances flexibility, compliance, redundancy, and vendor risk management.
