Understanding Bandwidth Costs
Cloud egress (outbound) bandwidth is one of the most significant and least predictable infrastructure costs. Providers charge differently: some by the GB with tiered pricing, others offer generous included bandwidth. During a DDoS attack, unwanted inbound traffic can also trigger massive egress costs from your applications responding to malicious requests.
AWS charges $0.09/GB for the first 10TB of egress, while Hetzner includes 20TB free with most servers. This difference means the same 10TB workload costs $900/month on AWS versus potentially $0 on Hetzner. Understanding these costs helps you choose the right provider and budget accurately.
How DDoS Attacks Inflate Bandwidth Bills
Volumetric DDoS attacks can generate hundreds of gigabytes of traffic per hour. Even with inbound traffic being free on most providers, your servers' responses to malicious requests generate billable egress traffic. Flowtriq helps you detect and mitigate attacks in seconds, preventing runaway bandwidth costs.
