Hello @gupta, Utkarsh
The cost-effectiveness of Azure SQL VM, Azure SQL Managed Instance, and Azure Synapse depends on your specific requirements and workloads.
Azure SQL VM provides the most compatibility with on-premises SQL Server deployments and is the most cost-effective option for workloads that require a high degree of customization and control.
Azure SQL Managed Instance is a fully managed PaaS offering that provides high-performance and scalability, with minimal maintenance and management overhead. This option is best suited for workloads that require a high degree of scalability and performance and are not as sensitive to cost.
Azure Synapse is a cloud-native data integration and analytics platform that provides a seamless experience for data integration, data warehousing, and big data analytics. This option is best suited for workloads that require advanced analytics and data integration capabilities and are not as sensitive to cost.
Based on the explanation above, you can make the choice with ease now.
