Answer 1

 $serverInfo = [
                'host' => "host",
                'username' => "username",
                'password' => "pwd",
            ];   
// use construct injection sftp : \Magento\Framework\Filesystem\Io\Sftp
$this->sftp->open($serverInfo); //the serverinfo is server config
$this->sftp->cd($path);//the path is you will upload path
$this->sftp->write($filename, $source); // filename and string data or local file name
$this->sftp->close();
