Embrace a phased approach, prioritizing critical workloads first. Leverage cloud-native services & implement auto-scaling to optimize resource utilization. It's like building a house - start with the foundation & essential rooms, then add the fancy stuff later. Don't forget to monitor & right-size regularly!

In my view, you must prioritize essential features and phases of the project. You can explore cost-effective cloud solutions and consider phased migrations to spread expenses over time. Additionally, seek potential grants or partnerships to offset costs and ensure careful monitoring of spending throughout the process.

Cost-Effective Cloud Migration: Key Strategies Plan meticulously: Thoroughly assess data and workloads. Identify essentials and avoid overspending. This detail ensures a smooth and cost-effective migration. Optimize relentlessly: Right-size instances, leverage reserved/spot, implement data tiering, deduplicate/compress, and automate. Migrate strategically: Prioritize critical apps/data, consider a hybrid model, and phase your migration to manage risk and costs. Control costs proactively: Use cloud cost management tools, allocate costs, set budgets, and forecast to avoid unexpected costs. Additional Tips: Utilize open-source solutions. Negotiate with providers. Train your team on cloud cost optimization. Regularly review and optimize.

Know and map your environment and the business, then define the keys steps and etl's (in the context of data engineering and architecture!) that are essential to the business. Start with only the essentials and control the increase in needs, building the environment so that it is healthy in opex. Leave the perfumery for later, and focus on the archiving and performance of your storage and scripts.

Consider hybrid cloud solutions to make a cloud-based data infrastructure migration work under budget constraints. You can control costs while gaining flexibility by keeping some operations on-premises and moving only critical components to the cloud. Prioritize optimizing your existing infrastructure before the migration to reduce inefficiencies. Explore open-source tools for migration and management to avoid expensive proprietary software. And... don't forget to collaborate with the cloud provider to negotiate cost-saving plans and leverage their expertise to streamline the migration process without exceeding your budget.
