What's the difference between core and node in Azure Integration Runtime - Microsoft Q&A (2024)

Hello @mikhail.zulkifli ,

Welcome to the MS Q&A platform.

In general, a node refers to a VM that is part of a cluster and "core" refers to a CPU core in a VM.

But In this context, "node" and "core" are used interchangeably to refer to computing resources.

We need to consider the below three factors when defining an integration runtime.

1. Cluster type
2. Cluster size
3. Time to live

Cluster type: General purpose or Memory optimized

Cluster Size(node size): Small, Medium or Large

Time to live: how long the cluster stays after completing a pipeline or external activity run if there are no other active jobs.

If you have 4 worker nodes, it means you have 4 CPU cores available. The number of nodes you will have depends on the cluster size.

If you choose the default cluster size(small), you will have 4 driver nodes and 4 worker nodes.

In total = 8 nodes( 4 driver nodes + 4 worker nodes) which is equal to 8 CPU cores (small cluster size)

For your question, when you choose Auto IR and small node, then the default cores are 4worker cores+ 4 Driver cores = total 8 V cores.

I hope this clarifies your question. Please let me know if you have any further questions here.
