Migration Strategies

Different migration strategies, such as Rehost, Refactor, and Rearchitect, are employed to move applications, data, or infrastructure from one environment to another. Each strategy has its advantages and disadvantages, and the choice depends on various factors.


Also known as Lift and Shift, this strategy involves moving applications or infrastructure as-is from one environment to another. It is typically the quickest and simplest. Rehosting may be ideal when there are budget or time constraints or if existing infrastructure doesn’t require significant changes.


Also known as Replatform, this strategy involves minor modifications or optimizations to the application or infrastructure. It may mean moving to a newer platform version or converting a monolithic application into a microservices architecture. Refactoring can help improve performance, scalability, and cost efficiency.


Also known as Redesign, this strategy involves significant changes to the application or infrastructure to align with modern cloud-native principles and architectures. It may include breaking up monolithic applications into microservices, adopting serverless technologies, or utilizing managed services provided by cloud providers. Rearchitecting can enable increased scalability, resilience, and flexibility.

Consider these factors when choosing a migration strategy

  • Assess the complexity of your application or infrastructure. Applications with tight dependencies, complex data models, or heavily intertwined components may require more effort during refactoring or rearchitecting.
  • Consider the urgency and timeline for migration. Rehosting can provide a quick solution, but refactoring and rearchitecting may take longer due to the need for code changes, testing, and deployment.
  • Evaluate the cost implications of each migration strategy. Rehosting typically has lower upfront costs, while refactoring and rearchitecting may require additional resources and investment.
  • Determine whether your application requires scalability or performance improvements. Refactoring and rearchitecting can provide opportunities to optimize and scale applications more efficiently.
  • Consider future business requirements or goals. Replatforming or rearchitecting applications using modern architectures can help ensure long-term compatibility, extensibility, and easier adoption of emerging technologies.

It’s also critical to assess the skills and resources within your organization. Do you have a migration expert on staff? Consider partnering with external experts.

Data migration techniques

Evaluate your specific requirements and choose the tools and technologies accordingly. Here are some best practices for data backup and migration:

Define your backup strategy

Determine what data needs to be backed up, how often, and where it will be stored. Consider factors like data sensitivity, regulatory requirements, and business continuity. Perform regular backups and store your data in multiple locations. Use on-premises servers, cloud storage, or offsite backups, then test to ensure they’re reliable.

It’s critical to protect your sensitive data during backup and migration processes by using safeguarded encryption methods.

Now, let’s talk about some tools and technologies that can facilitate a smooth data transfer

Cloud platforms offer interfaces and reliable transfer options for data migration to the cloud. Tools like Carbonite, Acronis, and EaseUS provide efficient solutions for moving data between different storage systems, such as transferring from an old computer to a new one.

If you need to migrate large databases, tools like AWS Database Migration Service, Microsoft SQL Server Migration Assistant, or Oracle Data Integrator can simplify the process.

Utilize protocols like FTP (File Transfer Protocol), SFTP (Secure File Transfer Protocol), or SCP (Secure Copy Protocol) to transfer data securely between servers or computers.

Depending on your needs, you can also consider hiring data migration specialists to handle the entire process, ensuring a smooth and hassle-free transfer.

  • Implement resource tagging to easily track and optimize resource usage, allocation, and costs.
  • Optimize storage by choosing the most cost-effective storage options, such as cold storage for infrequently accessed data.
  • Monitor and analyze usage to identify opportunities for optimization, such as downsizing or rightsizing instances.

Strategies for effective cost management

  • Leverage cloud provider cost estimation tools to anticipate and plan for cloud expenses and to help with budgeting and usage optimization.
  • Implement cost allocation tags to distribute costs to departments, projects, or teams by tagging resources appropriately – understand cost breakdowns to optimize spending.
  • Continuously monitor and analyze resource usage patterns to identify areas where costs can be reduced. This can include downsizing, resizing, or eliminating unused resources.
  • Commit to longer-term usage commitments with reserved instances, which can offer significant cost savings compared to on-demand instances.

Manage data security and compliance

  • Use robust authentication and authorization mechanisms, such as multi-factor authentication and role-based access control, to restrict access to sensitive data.
  • Encrypt your data at rest and in transit using industry-standard encryption.
  • Implement regular data backup practices to protect against data loss or corruption. Ensure backups are stored securely and can be easily restored if needed.
  • Conduct regular vulnerability assessments and penetration testing to identify and address any potential security vulnerabilities. 
  • Stay compliant with regulations by familiarizing yourself with relevant data protection laws and regulations specific to your industry and geography. Implement controls and procedures to ensure compliance, such as data retention and privacy requirements.

Implement robust identity and access management to control and manage user access to cloud resources based on need and principle of least privilege. 

It’s critical to regularly monitor and audit your cloud environment for security incidents and vulnerabilities. Use tools and services that provide real-time alerts and insights into security events. Automation is a big help here, with tools and scripts to enforce security processes like patch management, vulnerability scanning, and compliance checks. 

Prioritize security training,awareness, and maintain a culture of security awareness. Regularly educate your workforce about emerging threats and techniques to mitigate them.
