AWS Cloud Migration: Modernizing Business Infrastructure for Agility and Growth
As organizations continue to embrace digital transformation, migrating to the cloud has become a strategic priority. Among cloud providers, Amazon Web Services (AWS) stands out as the leading platform for scalable, secure, and cost-efficient cloud computing. AWS Cloud Migration enables companies to move their applications, databases, workloads, and infrastructure to the AWS environment to achieve higher agility, improved performance, and long-term operational resilience.
Whether businesses are shifting from on-premises environments or modernizing outdated systems, AWS offers a complete suite of tools, services, and frameworks for a smooth and efficient migration journey.
What is AWS Cloud Migration?
AWS Cloud Migration is the process of transferring digital assets—including applications, data, infrastructure, and workloads—from on-premises systems or other cloud platforms to Amazon Web Services. Migration can involve:
Rehosting (Lift and Shift)
Refactoring / Modernizing
Repurchasing SaaS solutions
Retiring or retaining legacy components
AWS provides automated tools, migration accelerators, and best practices to streamline the end-to-end journey.
