Elastic Load Balancing | Network Load Balancer Pricing Flashcards
Is there any impact of cross-zone load balancing on Network Load Balancer limits?
Network Load Balancer Pricing
Elastic Load Balancing | Compute
Yes. Network Load Balancer currently supports 200 targets per Availability Zone. For example, if you are in 2 Availability-Zones, you can have up to 400 targets registered with Network Load Balancer. If cross-zone load balancing is on, then the maximum targets reduces from 200 per Availability Zone to 200 per load balancer. So, in the example above when cross-zone load balancing is on, even though your load balancer is in 2 Availability Zones, you are limited to 200 targets that can be registered to the load balancer.
Q:How does Network Load Balancer pricing work?
You are charged for each hour or partial hour that a Network Load Balancer is running and the number of Load Balancer Capacity Units (LCU) used by Network Load Balancer per hour.
What is a Load Balancer Capacity Unit (LCU)?

Elastic Load Balancing | Compute
An LCU is a new metric for determining how you pay for a Network Load Balancer. An LCU defines the maximum resource consumed in any one of the dimensions (new connections/flows, active connections/flows, and bandwidth) the Network Load Balancer processes your traffic.
Is new connections/flows per sec same as requests/sec?

Elastic Load Balancing | Compute
No. Multiple requests can be sent in a single connection.
Will I be billed on Classic Load Balancers by LCU?

Elastic Load Balancing | Compute
No. Classic Load Balancers will continue to be billed for bandwidth and hourly charge
How do I know the number of LCUs a Network Load Balancer is using?

We will expose the usage of all three dimensions that constitutes a LCU via Amazon CloudWatch.
Will I be billed on all the dimensions in an LCU?
Network Load Balancer Pricing
Elastic Load Balancing | Compute
No. The number of LCUs per hour will be determined based on maximum resource consumed amongst the three dimensions that constitutes a LCU.
Will I be billed on partial LCUs?

Yes.
Is a free tier offered on a Network Load Balancer for new AWS accounts?
Network Load Balancer Pricing
Elastic Load Balancing | Compute
Yes. For new AWS accounts, a free tier for a Network Load Balancer offers 750 hours and 15 LCUs. This free tier offer is only available to new AWS customers, and is available for 12 months following your AWS sign-up date.
