6 R’s of Cloud Migration

Migrating to cloud computing is essential for companies that want agility, scalability, and cost-efficiency. The cloud migration process is complex and intimidating without a strategy. We’ll explore six common strategies to migrate cloud services, offering insights, best practices, and practical tips for organizations.

Understanding 6 R’s:

These six migration strategies are often referred to as the six R’s. They provide a framework that allows organizations to plan cloud migration projects systematically. These strategies include:

  • Rehost
  • Replatform
  • Repurchase
  • Refactor
  • Retain
  • Retire


Each approach offers unique advantages and considerations. This allows organizations to customize their approach according to their specific requirements, constraints, and objectives.

1. Rehost: Lift and shift for quick wins

Rehosting (lift-and-shift) involves moving servers or applications to public cloud infrastructure from their current hosting environment without major modifications. Considerations include:

  • Exporting applications via third-party export tools.
  • Creating images for deployment on cloud computing instances.
  • Containerization as a tool for the migration of monolithic applications.

2. Replatform: Optimizing during migration

Replatforming is a step up from the Lift and Shift approach. It optimizes the application architecture during migration. This strategy enables organizations to improve inefficiencies and shortcomings. Considerations include:

  • Identifying opportunities for performance optimization or cost reduction.
  • Cloud-native technologies or services for increased efficiency.
  • Minimize disruption by balancing migration speed and optimization efforts.

3. Repurchase: Transition to new solutions

Drop-and-shop or repurchasing involves switching to new services or products that cloud or third-party vendors offer. This strategy is ideal for organizations modernizing or migrating to cloud-native technologies. Considerations include:

  • Evaluation of compatibility and migration paths for existing applications.
  • Costs and licensing agreements associated with new solutions.
  • Plan for training and adoption of new technologies in the organization.

4. Cloud Services Refactored: Enhancing services for the cloud

Refactoring, or rearchitecting, involves fully redesigning and optimizing applications or services to utilize cloud-native features. This strategy is driven primarily by performance, scalability, or compliance requirements. Considerations include:

  • Opportunities for architectural modernization or improvement.
  • Impact on application performance, functionality, and user experience.
  • Balance refactoring with migration timelines and business objectives.

5. Retain Assets: How to preserve on-premise assets

Retention is retaining some aspects of an IT portfolio within the on-premises environment while moving other components into the cloud. This hybrid approach is ideal for organizations with specific compliance, regulatory, or performance requirements. Considerations include:

  • Identify critical workloads and applications that aren’t ready for migration to the cloud.
  • Hybrid cloud solutions for maintaining connectivity and data consistency.
  • Planning ongoing management and integration of on-premises and cloud environments.

6. Retired: Streamlining operations

To streamline operations and cut costs, retiring involves decommissioning assets or services that are obsolete or underutilized. This strategy allows organizations to focus resources on high-value services while reducing unnecessary complexity. Consideration includes:

  • Conducting an inventory and assessment of assets and services.
  • Assessing the impact on business and dependencies of retiring specific components.
  • A phased retirement approach is the best way to minimize disruptions and reduce risks.

Benefits of cloud migration and optimization

Some of the benefits of cloud migration and optimization include:

Flexibility and scalability:

Cloud environments offer elastic resources that can be dynamically scaled up or down based on demand.
Cloud Services allow organizations to deploy and provision resources instantly. This allows rapid development and deployment of new applications and services.

Savings and efficiency:

Cloud providers offer a model that allows businesses to pay only for resources they use. This reduces upfront capital costs while optimizing operational costs.
Organizations can optimize resource use and reduce waste using cloud optimization technologies like instance scheduling, automated scaling, and right-sizing. This will lead to significant long-term savings.

Security and compliance:

Cloud providers offer robust security features, including compliance certifications, data encryption, and robust security features. Cloud providers also offer identity and access monitoring and security monitoring.

Organizations receive regular security patches and updates to keep them up-to-date with new threats. They can also maintain regulations and compliance.

Increased performance and reliability:

Cloud Services are accessible in many geographical regions. This allows companies to distribute workloads and applications closer to end users. It reduces latency and improves performance.
Cloud service providers offer high availability and redundancy. This ensures that data and applications are available without interruption through automated failover mechanisms and replica mechanisms.

Collaboration and streamlined operations:

Cloud environments offer consoles and tools that are managed centrally to simplify administration, monitoring, and troubleshooting. This reduces operational complexity and increases efficiency.
Cloud Collaboration Platforms enable seamless communication and collaboration among remote teams. They allow real-time collaboration and sharing of files, documents, and information anywhere.

Understanding Cloud Migration Process – A Step-by-Step Guide

Cloud migration can transform a business. Before making any decisions, companies must thoroughly understand the migration process. Let’s look at the main steps in moving to the cloud and how companies can successfully navigate each phase.

Build your business case and define your strategy

To successfully migrate your business to the cloud, you must define your strategy and build a convincing business case. The companies must identify the value they can gain by moving their business to the cloud. It is important to align the migration goals with the business’s overall goals and outcomes.

Key activities:

  • Identify objectives and outcomes.
  • Determine the applications that are suitable for migration.
  • Determine the best cloud environment for your needs.

Discovery and assessment

After establishing a strategy, you must comprehensively discover and assess the existing infrastructure, data, and applications. The current architecture is scanned and assessed to determine which data and applications are candidates for migration.

Key activities:

  • Application Discovery and Dependency Mapping.
  • Risk assessment based on current usage.
  • Pre-migration predictive analysis.
  • Cloud migration assessment is used to make informed decisions and minimize risks.

Cloud migration

After thoroughly understanding the landscape and the company’s objectives, they can move on to the migration phase. The heavy lifting is done here, with the migration of data and applications to the cloud. This may include modernizing applications to the cloud, creating new cloud-native apps, and transforming architecture and infrastructure.

Key activities:

  • Modernizing applications for cloud computing.
  • It helps in developing new cloud-native applications.
  • Transforming Architecture and Infrastructure
  • It has automated management and migration tools to improve efficiency and consistency.
