Azure SQL Managed Instance is a scalable cloud data service that provides the broadest SQL Server database engine compatibility with all the benefits of a fully managed platform as a service. Depending on your scenario, Azure SQL Managed Instance might offer more options for your database needs.
Like Azure SQL Database, Azure SQL Managed Instance is a platform as a service (PaaS) database engine, which means that your company will be able to take advantage of the best features of moving your data to the cloud in a fully-managed environment. For example, your company will no longer need to purchase and manage expensive hardware, and you won’t have to maintain the additional overhead of managing your on-premises infrastructure. On the other hand, your company will benefit from the quick provisioning and service scaling features of Azure, together with automated patching and version upgrades. In addition, you’ll be able to rest assured that your data will always be there when you need it through built-in high availability features and a 99.99% uptime service level agreement (SLA). You’ll also be able to protect your data with automated backups and a configurable backup retention period.
