Concepts

Managed Instance in Azure is a fully managed instance of SQL Server that provides a seamless transition for moving your on-premises SQL Server workloads to the cloud. It offers a range of benefits such as automatic patching and version upgrades, built-in high availability, and the ability to scale compute and storage independently. Let’s explore the key features and advantages of using Managed Instance.

1. Compatibility and easy migration:

Managed Instance is designed to provide compatibility with the latest on-premises SQL Server versions. You can migrate your existing SQL Server databases to Managed Instance with minimal effort and code changes. The compatibility features ensure that your applications continue to work seamlessly in the cloud.

2. Fully managed service:

With Managed Instance, Microsoft handles the infrastructure management tasks, such as patching, backups, and monitoring, allowing you to focus on your databases and applications. This reduces the administrative overhead and frees up your time to concentrate on other critical tasks.

3. High availability and disaster recovery:

Managed Instance provides built-in high availability with automatic database backups and point-in-time restore capabilities. It leverages Azure’s regional availability to ensure your databases are protected against hardware failures and other outages. You can also configure geo-replication for disaster recovery purposes.

4. Scalability and performance:

Managed Instance offers flexible compute and storage options. You can easily scale up or down the compute resources depending on your workload requirements. The storage can be expanded without any downtime or application interruption. Additionally, Managed Instance supports features like in-memory OLTP and columnstore indexes to enhance query performance.

5. Security and compliance:

Security is a top priority for Managed Instance. It provides a secure environment with features such as Azure Active Directory authentication, transparent data encryption, and firewall rules. Managed Instance is also compliant with industry standards and regulations, such as GDPR, HIPAA, and ISO.

SQL Server on Azure Virtual Machines (VMs)

Now, let’s also discuss SQL Server on Azure Virtual Machines (VMs), another option for running SQL Server in the Azure cloud.

1. Full control and customization:

SQL Server on Azure VMs allows you to have complete control over the SQL Server environment. You can choose the version and edition of SQL Server, configure custom settings, install additional software, and manage the underlying operating system. This makes it suitable for complex applications with unique requirements.

2. Lift and shift migration:

If you have existing on-premises SQL Server deployments, SQL Server on Azure VMs offers a lift and shift migration approach. You can migrate your databases to VMs with minimal modifications, replicating your on-premises environment in the cloud.

3. Hybrid scenarios:

SQL Server on Azure VMs facilitates hybrid scenarios where you can connect your on-premises infrastructure with the cloud. This allows you to extend your existing environment to take advantage of cloud resources, such as backup and disaster recovery, scalability, and analytics.

4. Cost optimization:

SQL Server on Azure VMs provides cost optimization options by allowing you to choose the VM size and performance characteristics based on your workload requirements. You can also leverage Azure Hybrid Benefit, which enables you to use your existing SQL Server licenses with eligible Azure VMs, reducing your overall cost.

It’s important to choose between Managed Instance and SQL Server on Azure VMs based on your specific needs. Managed Instance offers a fully managed service with greater simplicity, whereas SQL Server on Azure VMs provides more control and customization options. Assess your workload requirements, budget, and administrative preferences before making a decision.
