Graviton

ARM-based; 20-40% cheaper than x86 equivalents.

Spot pricing for Graviton instances. Stack the discounts.

Spot pool is smaller; diversify across types.

Test apps on ARM in dev. Most just work; some have ARM-specific issues.

Container images: build multi-arch. Images run on either arch transparently.
