Cloud phones are overkill and way too expensive for managing basic IG accounts. You don't need dedicated physical hardware for each account—just switch to an anti-detect browser paired with static ISP or 4G/5G mobile proxies.
Your suspicion is right: posting from multiple accounts on the same phone/IP on the same day triggers Instagram's device-linking detection. An anti-detect browser isolates each account's canvas, cookies, and device fingerprints completely, while unique IPs keep them clean. It's much cheaper and far easier to scale.
