Guide to Cloud Migration: From PaaS to IaaS

Migrating from Platform as a Service (PaaS) to Infrastructure as a Service (IaaS) involves a comprehensive approach that addresses assessment, planning, provider selection, architecture design, and execution while avoiding common pitfalls such as inadequate planning, underestimated security needs, and overlooked cost controls. This process requires evaluating current PaaS environments, choosing an appropriate IaaS provider, and designing a scalable architecture using tools like Infrastructure as Code (IaC). Migration strategies can range from lift-and-shift to refactoring, depending on the desired level of optimization and cost-efficiency. The transition emphasizes the importance of rigorous testing, resource optimization, and security measures to ensure performance and reliability. Automation tools like Qovery simplify migration by providing rapid deployment, auto-scaling, compliance readiness, and AI-driven assistance, thus facilitating a smooth transition and enabling businesses to achieve greater control, scalability, and cost efficiency.
