Should I host on Cloud99, Maxer, or AWS Frankfurt for Hungarian data residency?

Depends on your volume + DevOps tolerance + data-residency posture:

• Cloud99, Hungarian managed-hosting (Budapest DCs). Strong on Hungarian customer support (HU + EN), familiar with Online Számla / NAV + ÁFA setups. Good for HUF 50M, 500M Magento stores. Less auto-scaling than hyperscalers; more hands-on DevOps from us.
• Maxer Hosting, another Hungarian provider, popular with Shoprenter migrants. Hungarian-language admin + invoice in HUF. Mid-tier reliability, good price/perf.
• AWS Frankfurt (eu-central-1), not technically Hungarian residency but Frankfurt is the closest hyperscaler region (latency ~10-15ms to Budapest), GDPR-compliant, NAIH-acceptable. Best for HUF 500M+ stores wanting auto-scaling, Cloudfront, RDS, ElastiCache.
• Adobe Commerce Cloud (Frankfurt region), best if you’re already on Adobe Commerce license. Fully managed, 24/7 Adobe support, Fastly CDN. Costs €25k+/yr.
• OVHcloud / Hetzner Helsinki, budget EU options, work fine for Hungary if you don’t need ms-level latency.

NAIH doesn’t mandate HU-only hosting, but some conservative Hungarian B2B clients (especially in regulated sectors) prefer HU-soil residency for optics, in that case Cloud99 / Maxer win on the procurement-questionnaire alone.
