No, you only pay for egress (outbound traffic) not ingress.  You pay for operations (GETS and PUTS) on each side but the total costs are going to be dominated by the egress.<p>In addition to free egress within GCP regions, we also recently announced reduced egress pricing for major CDN partners: <a href="https:&#x2F;&#x2F;cloud.google.com&#x2F;interconnect&#x2F;cdn-interconnect" rel="nofollow">https:&#x2F;&#x2F;cloud.google.com&#x2F;interconnect&#x2F;cdn-interconnect</a> .<p>So how much data do you store and serve? ;)
