Hello @Bojan Zivkovic
In an Active-Standby Azure VPN Gateway design, you typically do not pay full price for both instances. Unlike Active-Active configurations, where both gateways are actively processing traffic and incur full charges, Active-Standby setups usually involve one instance being on standby, which may lead to cost savings.
However, in an active-active configuration, you would indeed pay for both instances, as they are both actively engaged in managing traffic. This means that while the active-active setup allows for greater availability and load balancing, it's also typically more expensive due to the need for two public IP addresses and the two instances being billed.
Pricing Differences:
- Active-Standby Mode: You are charged for a single gateway instance at any given time. The standby instance is available for failover but does not incur additional charges unless it becomes active.
- Active-Active Mode: Both instances are always active, meaning you pay for both instances simultaneously.
Azure VPN Gateway pricing is based on the gateway SKU and the number of tunnels. You can check the official Azure VPN Gateway pricing for detailed cost breakdowns.
Hope the answer helps!
