The nodes of a Snaplex need to communicate among themselves, so it is important that each node can resolve each other's host names. This requirement is crucial when you are making local calls into the Snaplex nodes for the execution of the Pipelines instead of initiating it through the SnapLogic Platform. The Pipelines are load-balanced by SnapLogic with Tasks passed to the target node.
Communication between the customer-managed Groundplex and the SnapLogic-managed S3 bucket is over HTTPS, with TLS enforced by default. The AWS-provided S3 URL also uses an HTTPS connection, with TLS enforced by default. If direct access from the Groundplex to the SnapLogic AWS S3 bucket is blocked, then the connection to the AWS S3 bucket communication falls back to a connection through the SnapLogic Control Plane that still uses TLS 1.2.
To successfully implement the Zero Trust policy on the Kubernetes in any environment, use the following S3 URLs.
snaplogic.com is required for all users.
snaplogic-prod-sldb.s3.amazonaws.com and s3.amazonaws.com access is required for file operations that use
sldbprotocol (For example, FileReader / FileWriter Snaps that are configured to usesldbprotocol).

Network Guidelines for Snap Usage
In the SnapLogic Platform, the Snaps actually communicate to and from the application endpoints. The protocols and ports required for this communication are mostly determined by the endpoints themselves and not by SnapLogic. Cloud and SaaS applications commonly communicate using HTTPS, although older applications and non-cloud or SaaS applications might have their own requirements.

Diagnostic test | Recommended value | Examples of current value displayed in the diagnostic test |
Nodes have insufficient swap space | If the maximum value is not present, the system displays the value of 50% of the RAM configured or 8GB, whichever is greater. | If the value is not as per the recommended value the current value is displayed in red. |
Max Slots | If there is no minimum value, then the recommended value is calculated as follows: RAM configured or 8GB) * 2000 (max value) rounded to the nearest 500. | Example: If the maximum value is 3840, the current value displayed is 4000 |
Thread limit | Minimum value = 65000 | Displays the thread limit in red if the value is below the recommended value. Example: 4000 |
Max file descriptors | If there is no maximum value and the minimum value is 65000, then the recommended value should be 65000. | Example: 65535 |
Max jvm heap | The minimum and the recommended value is calculated as follows: Minimum value = 12GB Recommended value = 12GB | Example: 12.44GB |
RAM configured | Minimum value = 4GB Recommended value = 4 GB | Example: 2.73% |
RAM available | More than 15 minute period per day where memory utilization is > 75% or average memory utilization is > 60% | Example: 2.78% |
Disk storage configured | Minimum value: 40GB Recommended value: 100GB | Example: 39.98 GB |
