VM.Standard.A1.Flex shape (Arm-based Ampere A1 Compute): Because the VM.Standard.A1.Flex shape is a flexible shape, you can customize the number of OCPUs and amount of memory that are allocated when you create or resize an instance. You can use all of the Always Free OCPUs and memory to create a single instance, or create multiple smaller instances that each use a portion of the resources.
Processor: 4 OCPUs total, which you can allocate flexibly
Memory: 24 GB total, which you can allocate flexibly
Networking: The network bandwidth and number of VNICs scale proportionately with the number of OCPUs. For details, see Flexible Shapes.
