Instance Classes & Storage Options for Oracle to Azure VM Migrations
Author: Glenna Coultas | | July 15, 2021
Choosing the right instance class and instance storage for your Oracle to Microsoft Azure VM migration is essential for getting the most out of your technology investment. The correct choice depends on your use case, current and future capacity requirements, and the specific Oracle workload you’re addressing.
Database Instance Classes for Your Oracle to Microsoft Azure VM Migration
When you set up Azure VM, you select a database instance class for specifications that include the virtual CPU and RAM.
The most affordable instance class is the B-series. It comes with one vCPU and one GB RAM, with pricing that begins at $0.008 per hour. The ideal use cases for this option are workloads that are not typically resource intensive, but they may require burst capacity every so often. The B-series is also a good choice if you want to test Azure VM without a significant financial investment.
Compute Optimized F
Resource-heavy Oracle workloads find an excellent match with Azure VM’s F-series. When your primary focus is on getting the most compute power possible, you’ll want to use this instance class. You get access to two vCPUs based on Intel Skylake, along with 4 GB RAM, with pricing starting at $0.085 per hour.
General Purpose D
Oracle database workloads are rarely at one extreme or another when it comes to resources. When you have databases that need a good balance between CPU and RAM to accommodate a flexible range of workloads, the D-series comes into play. You get two vCPUs and 8 GB RAM with costs starting at $0.096 per hour.
Are you working with a lot of analytical workloads or other use cases that demand significant memory? The E-series gives you access to a massive 16 GB RAM with two vCPUs for $0.126 per hour.
Instance Storage Options for Your Oracle to Azure Migration
The storage you choose for your Azure VM instance is just as important as the database class.
Magnetic: Magnetic hard disk drives are the most affordable option, but they’re also the slowest. Use these for test environments and other Oracle database experiments.
General-purpose SSD: Solid state drives provide a good mix of performance and pricing, allowing you to use this option for a wide range of use cases.
Provisioned IOPS: Microsoft Azure VM allows you to provision IOPS based on your workload’s requirements. This storage option is excellent for your production workflows.
