The c5.24xlarge is a compute-optimized AWS EC2 instance: 96 vCPU and 192 GiB of memory, 2.00 GiB per vCPU. In the name, "c" stands for compute, "5" is the generation and "24xlarge" is the size within the c5 family. It runs on Intel Xeon Platinum 8275L at 3.4 GHz, and AWS introduced it in June 2019. AWS has since shipped c6i, c7i, c8i and c9g; c6i.24xlarge is the direct replacement at this size. No single Spot node covers 96 vCPU and 192 GiB, so the equivalent is a fleet: 6 × ch.vs1.2xlarge, 96 vCPU and 192 GiB in total, about 94% below the US East (N. Virginia) on-demand rate. Spot delivers compute as managed Kubernetes, so a node pool of that size is the native shape of the answer rather than a workaround — provided the workload scales horizontally.

c5.24xlarge gives you 96 vCPU and 192 GiB in a single machine. The largest comparable Spot node, ch.vs1.2xlarge, is 16 vCPU and 32 GiB, so the equivalent here is 6 nodes rather than one.
Spot runs as managed Kubernetes, so a 6-node pool is the normal way to run things rather than a workaround. If your workload already sits behind a load balancer, a queue or a scheduler, it spreads across them without changes. If it needs all 96 cores and 192 GiB in one process, it does not.
