SQL Server Lift & Shift on Azure - SQL Saturday 921
This document discusses options for migrating SQL Server databases to Azure, specifically focusing on lift and shift strategies using Azure SQL Database or SQL virtual machines. It provides an overview of the different Azure SQL offerings including databases, managed instances, and SQL VMs. The key advantages and use cases of each option are outlined. The document also addresses some common myths around choosing virtual machines over Azure SQL Database, noting that the database service offers fully managed high availability, security, backups and more without ongoing maintenance.

This model allows you to independently choose compute and storage resources. It also allows you to use Azure Hybrid Benefit for SQL Server to gain cost savings. Best for customers who value flexibility; control and transparency Customers can select compute and storage independently Allows customers to right-size their compute requirements in the cloud vCore sizing offers flexibility of choice Database Transaction Unit (DTU) model.

- #36 Azure SQL Database serverless is our answer to cost-effectively resourcing these types of unpredictable and intermittent workloads. It is a dynamically scaling, on-demand version of Azure SQL Database that eliminates the complexity of resourcing and managing unpredictable workloads. Simply create a serverless database and connect your application, with no upfront resource configuration required. Serverless SQL databases automatically pause, resume and scale compute based upon your app’s requirements, making them particularly cost effective for variable or unpredictable workloads – or when you’re simply unsure of your requirements. With resources available on-demand, serverless SQL databases optimize costs with pay per-second billing that aligns with the app’s performance, so you only pay for the compute resources you use . Built upon the SQL Server architecture, serverless SQL databases are fully-managed, always up to date and highly available with a 99.99% uptime guarantee. Combined with built-in intelligence to optimize database performance and security, serverless SQL Databases help you be more productive so you can focus more on what you do best, building great apps faster and more cost effectively.
