A **Manager** is used to manage all incoming and outgoing connections to a server.

On startup all remote servers must be specified. 
From that individual connections will be spawned to each remote server, 
or incoming requests will be hooked up to the appropriate connection.

To get a connection to a specific server, use `Manager.Connection(host)` to get a connection to the specified host.
From this connection individual requests can be made.

```

> NOTE: A zero value of `requests_max` means MinIO will automatically calculate requests based on available RAM size and that is the default behavior.

### Configuring connection (wait) deadline

This value works in conjunction with max connection setting, setting this value allows for long waiting requests to quickly time out when there is no slot available to perform the request.

MINIO_NOTIFY_POSTGRES_MAX_OPEN_CONNECTIONS (number)             maximum number of open connections to the database, defaults to '2'
```

> NOTE: If the `max_open_connections` key or the environment variable `MINIO_NOTIFY_POSTGRES_MAX_OPEN_CONNECTIONS` is set to `0`, There will be no limit set on the number of

 * HTTP/2 support allows all requests to the same host to share a socket.
 * Connection pooling reduces request latency (if HTTP/2 isn’t available).
 * Transparent GZIP shrinks download sizes.
 * Response caching avoids the network completely for repeat requests.

OkHttp perseveres when the network is troublesome: it will silently recover from common connection

        - it connects to K8S using the kubeconfig and JWT token copied from install-cni to get Pod and Namespace. Since this is a short-running command, each invocation creates a new connection.
        - If so, calls `istio-iptables` with params to setup pod netns
        - If ambient, sets up the ambient logic.

- `istio-iptables`

Similarly, if your TLS certificates do not have the IP SAN for the MinIO server host, the MinIO Console may fail to validate the connection to the server. Use the `MINIO_SERVER_URL` environment variable  and specify the proxy-accessible hostname of the MinIO server to allow the Console to use the MinIO server API using the TLS certificate.

- MinIO object storage set up per <https://min.io/docs/minio/linux/index.html>
- Veeam requires TLS connections to the object storage.  This can be configured per <https://min.io/docs/minio/linux/operations/network-encryption.html>
- The S3 bucket, Access Key and Secret Key have to be created before and outside of Veeam.

The field of `getObjectContext` means the input and output details for connections to MinIO. It has the following fields:
