Cost Attribution
Data transfers between services can be a large but opaque portion of total cloud infrastructure costs. Know which service pairs generate the most cross zone and egress traffic to optimize their behavior and verify that changes to traffic patterns have the desired effects.
Avoid unnecessary cross zone traffic in microservices
Platforms like Kubernetes make it incredibly easy to deploy containers across zones and mistakenly generate extremely large network transfer bills.
Measure egress network traffic
Understand the service source and destination of all traffic that leaves your environment.
Quantify the costs of high availability
Measure the impact of operating cross zone or cross region to trade off availability, cost, and performance.
Flowmill gave us visibility into an area we generally don’t look at. We never dealt too deeply into the networking itself. We never really realized how important it was. No one, even Amazon, provides good tooling and detail in this area or a means of turning this detail into knowledge.
