Migrating from an on-premises data center to a cloud environment is a critical step for many organizations seeking to enhance scalability, flexibility, and cost-efficiency. One of the most popular approaches for this transition is the “lift and shift” method, where applications, workloads, and data are moved to the cloud with minimal changes. This strategy allows businesses to quickly reap the benefits of cloud computing without the need for extensive re-architecting of their systems.

Among the various cloud service models available, Infrastructure as a Service (IaaS) stands out as the most suitable for lift and shift migrations. IaaS offers a virtualized version of the traditional hardware infrastructure, providing familiarity for IT staff, control over the operating environment, and the ability to scale resources as needed.

In this blog, we will explore why IaaS is the ideal choice for lift and shift migrations, and highlight some leading IaaS providers.

Why IaaS is Best Suited for Lift and Shift

Minimal Changes Required: IaaS facilitates the lift and shift migration of applications and data with minimal architectural modifications. This simplifies the transition to the cloud, ensuring continuity without extensive redesigns, and reducing operational disruption.

Familiarity: IaaS provides a virtualized environment akin to traditional on-premises hardware, familiar to IT teams. This familiarity streamlines management processes and supports operational continuity, leveraging existing skills and practices.

Control and Flexibility: Organizations retain control over operating systems, storage, and applications with IaaS, similar to managing on-premises infrastructure. This control ensures seamless integration and customization to meet specific business needs.

Scalability: IaaS offers scalable computing power and storage resources on-demand. This flexibility eliminates the need for upfront hardware investments, enabling agile resource allocation to match fluctuating workload demands.

Ease of Deployment: IaaS simplifies deployment by minimizing the need for extensive architectural changes, ensuring a smoother transition to cloud environments.

Resource Flexibility: Businesses can scale computing resources according to demand with IaaS, optimizing performance and operational efficiency without upfront hardware costs.

Cost Efficiency: Adopting IaaS reduces operational costs associated with hardware maintenance, space, and energy consumption, promoting cost-effective cloud migration strategies.

Management Simplicity: IaaS environments are managed similarly to on-premises systems, providing familiarity and ease of management for IT teams.

Examples of IaaS Providers

Amazon Web Services (AWS) EC2: AWS EC2 provides diverse instance types tailored for various applications. It supports scalability and performance optimization, enabling businesses to deploy and manage applications efficiently.

Microsoft Azure Virtual Machines: Azure VMs offer robust support for multiple operating systems and seamless integration with existing on-premises systems. Azure’s global infrastructure ensures high availability and compliance.

Google Cloud Compute Engine: Google Cloud Compute Engine features customizable VM configurations and a pay-per-second billing model. It supports efficient resource management and cost optimization for businesses of all sizes.

Considerations during an IaaS lift and shift migration:

Compatibility: Verify operating systems, databases, and applications are compatible with the IaaS platform to avoid compatibility issues during lift and shift migration.

Resource Sizing: Accurately assess CPU, memory, and storage requirements to ensure optimal performance and scalability in the cloud environment.

Data Migration: Plan a secure and efficient transfer of data to prevent data loss, ensuring integrity and minimal downtime during the lift and shift migration process.

Performance Testing: Conduct thorough tests to evaluate network latency, application responsiveness, and overall performance to meet user expectations post-migration.

Security: Implement robust security measures including encryption, access controls, and compliance certifications to protect data and meet regulatory requirements in the cloud.

Cost Management: Optimize costs by choosing appropriate pricing models, monitoring resource usage, and scaling resources based on demand to avoid unnecessary expenses.

Monitoring Tools: Utilize monitoring tools provided by the IaaS platform to track resource utilization, identify performance bottlenecks, and optimize infrastructure efficiency.

Backup Strategy: Develop a comprehensive backup strategy with automated backups and data replication across regions to ensure data resilience and quick recovery in case of failures.

Training: Provide training for IT team on managing and troubleshooting the IaaS environment effectively to minimize operational issues and maximize productivity.

Integration Testing: Conduct rigorous integration testing to verify application functionality, data integrity, and compatibility with other systems post-migration to ensure a seamless transition to the cloud.


When undertaking a “lift and shift” migration from an on-premises data center to the cloud, Infrastructure as a Service (IaaS) emerges as the optimal choice.
