Copy to Cloud requires outbound access on ports depending on your environment configuration and requirements so that objects can be copied from ECS to ECS or Amazon S3 over the internet.
Table 3 shows network port requirements for Copy to Cloud. We recommend opening the HTTPS port only to create a secure encrypted connection for Copy to Cloud.
From | To | Protocol | Port (Type) |
ECS | Amazon S3 | TCP | 443 (HTTPS) / 80 (HTTP) |
ECS | ECS | TCP | 9021 (HTTPS) / 9020 (HTTP) |
Note: If the target ECS is configured with a network load balancer, the defined HTTPS/HTTP ports on the load balancer will be used and opened for Copy to Cloud.
