What is cloud migration?
Cloud migration is the process of moving an organization’s applications—including data, services, processes and other business components—to a cloud computing environment. It typically involves transitioning these elements from on-premises data centers and servers to the cloud or from one cloud environment to another.
Among the cloud migration approaches are: greenfield, which entails building applications on cloud with a “cloud-first” approach and ingesting cloud-native functionality; brownfield, which includes rehosting, replatforming, rearchitecting and refactoring; and a combination of greenfield and brownfield strategies.
What are the business benefits of cloud migration?
By migrating some or all of its data assets to the cloud, an organization can achieve the following benefits:
- Business transformation. Move and innovate faster, modernize aging infrastructure, scale globally, get better insights from data and restructure organizational models to create better customer experiences.
- Digital transformation. Achieve digital transformation by enhancing agility, enabling better use of advanced technologies and facilitating culture change.
- Data center consolidation. Spend less time managing data centers and more time running the business by migrating to the cloud.
- Cost savings. Control costs using consumption-based pricing and eliminate capex-heavy on-premises environments.
- Agility and scalability. Use autoscaling and scalability to meet the organization’s peak demands without provisioning for excess capacity.
- Geographic reach. Access applications from any location, on any device, leveraging the connectivity backbone of cloud service providers (CSPs).
- Integration. Integrate with other systems (application programming interface) seamlessly—and cost-effectively.
- Simplicity. Hasten and simplify the setup of data and applications and make updates automatic.
- Low maintenance. Turn responsibility over to a CSP for maintaining hardware, software and network infrastructure.
