Fly.io is strongest for full-stack apps needing global low latency. IONOS is strongest for budget shared/VPS hosting. Here's how they stack up on price, uptime, and support.

Feature	Fly.io	IONOS
Starting price	$0.01/mo	$0.02/mo
Best for	Full-stack apps needing global low latency Docker-native deploys Small teams wanting per-second billing Postgres close to compute	Budget shared/VPS hosting Windows workloads EU-based data residency Granular building-block cloud pricing
Stated uptime SLA	No blanket platform SLA published; Enterprise support plans include custom SLAs	99.99%
Storage	SSD	NVME
Regions	35	6
Managed Kubernetes	Yes	Yes
Support channels	Community forum, Docs, Ticket (paid support plans), Enterprise Slack (Enterprise plan)	24/7 Phone, Ticket, Docs, Live Chat
Compliance	SOC 2	GDPR, ISO 27001
Hidden costs to watch for	Machine prices vary by region -- the reference/base rates in this dataset are for the Amsterdam (ams) region; several regions carry a price premium Extra RAM beyond a preset's base allocation is billed separately (~$5 per 30 days per additional GB, prorated per-second) Stopped Machines still incur a rootfs storage charge of $0.15/GB per month Volume snapshots are billed at $0.08/GB per month above the first 10GB free per month Dedicated (non-shared) egress IPs are billed hourly (~$0.005/hr, ~$3.60/mo) in addition to the free shared IPv4 Cross-region private networking traffic is billed per GB and varies sharply by region group (Africa/India up to $0.12/GB egress) Wildcard/extra SSL certificates beyond the first 10 free per org are billed monthly	Intro pricing on VPS+ and Web Hosting plans (e.g. $2/mo, $1/mo) is a 3-month or 1-year promotional rate on a 1-year contract; renewal pricing after the promo/contract period is 2-6x higher Additional static IPv4 addresses billed at $6.00 per 30 days each Outbound data transfer beyond the free 2TB pooled allowance is tiered: $0.036/GB (2-10TB), dropping to $0.018/GB beyond 150TB Windows Server and RedHat Enterprise Linux require separate per-vCPU/core license surcharges on top of Compute Engine/Cube pricing IONOS CLOUD Compute Engine building-block pricing (Cores + RAM + Storage priced independently) can be harder to estimate than fixed-tier competitors without using their price calculator
