UDP or TCP packets in Java AppEngine

[jesus cabrera polo]

Hello, Im migrating a project to AppEngine and i want to get the packet from several devices . Before in a centos server , i had a java service that open socket and listen for udp packet and store it in bd .
there are not to much information about it  only that socket it is for paid app , can not be a listen socket .
i read it using a net.DatagramSocket like :
socket = new DatagramSocket(port);
byte[] data= new byte[300];
DatagramPacket packet= new DatagramPacket(data, data.length);
socket.receive(packet);

Can you please suggest me a alternative to read the device packets in Appengine.?
Thanks a lot.

Really in Appengine you should be receiving the data in HTTP format*. Rather than arbitrary 'packets'. 

As you say you can't open listening sockets. AppEngine is really setup for handling HTTP requests. 

*( there are interfaces to transform other protocols into HTTP for you eg receiving Emails, XMPP messages, or WebSocket style interace via the Channel API - various underlying protocols in reality) 

Compute Engine would be a better choice

https://cloud.google.com/compute/

Having said that there is

https://cloud.google.com/appengine/docs/managed-vms/

which is estentially a AppEngine managed Cloud Compute instance. So you get the great APIs of appengine, but a bit more flexiblity - I think that would include opening listening sockets.
