High scalable document generation service
Disclosed are some implementations of systems, apparatus, methods and computer program products for implementing a scalable computing system. The scalable computing system includes an intermediate system that facilitates communications between a core server system and a third-party system. The core server system processes a client request for a third-party service in association with a web page having a corresponding web address. The intermediate system communicates with the core server system to obtain a session token, and transmits the session token and web address to the third-party system. The third-party system may then access the web page via the web address using the session token.
1. A method, comprising:
processing, by a server system, a client request associated with a web page, the client request being received from a client device;

wherein obtaining, by the server system, the first document includes retrieving the first document from a storage medium responsive to the document ready message.
6. The method of claim 5 , wherein transmitting the message is performed via a first queue of a second set of queues, the document ready notification message being received from the third-party service via a second queue of the second set of queues.
7. The method of claim 1 , further comprising:
configuring, by the server system, a token lifetime associated with the session token;
wherein authenticating the web page request using the session token includes verifying that the session token has not expired.
8. A system comprising:
a database system implemented using a server system, the database system configurable to cause:
processing, by a server system, a client request associated with a web page, the client request being received from a client device;
responsive to the client request, transmitting, by the server system, a third-party service request including a web address associated with the web page and a user identifier to an intermediate system, the third-party service request being a request for a third-party service;
processing, by the server system, a session token request received from the intermediate system, the session token request including the user identifier;
generating, by the server system, a session token using the user identifier;
transmitting, by the server system, the session token to the intermediate system responsive to the session token request;
processing, by the server system, a web page request including the web address and session token, the web page request being received from a third-party system, wherein the session token is not provided by the server system directly to the third-party system;
authenticating, by the server system, the web page request using the session token;
responsive to authenticating the web page request, transmitting, by the server system, the web page to the third-party system;
obtaining, by the server system, a first document associated with the web page and generated by the third-party system; and
providing, by the server system, the first document to the client device.
9. The system of claim 8 , wherein obtaining the first document comprises:
retrieving the first document associated with the web page from a storage medium responsive to receiving a document ready message from the intermediate system.
10. The system of claim 9 , wherein transmitting the third-party service request includes providing the third-party service request via a first queue of a first set of queues, and wherein the document ready message is received via a second queue of the first set of queues.
11. The system of claim 8 , the database system further configurable to cause:
transmitting, by the intermediate system, a message including the session token and web address to the third-party service.
12. The system of claim 11 , the database system further configurable to cause:
processing, by the intermediate system, a document ready notification message received from the third-party service; and
transmitting, by the intermediate system, a document ready message to the server system responsive to processing the document ready notification message;
wherein obtaining, by the server system, the first document includes retrieving the first document from a storage medium responsive to the document ready message.
13. The system of claim 12 , wherein transmitting the message is performed via a first queue of a second set of queues, the document ready notification message being received from the third-party service via a second queue of the second set of queues.
14. The system of claim 8 , the database system further configurable to cause:
configuring, by the server system, a token lifetime associated with the session token;
wherein authenticating the web page request using the session token includes verifying that the session token has not expired.
15. A computer program product comprising computer-readable program code capable of being executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code comprising computer-readable instructions configurable to cause:
processing, by a server system, a client request associated with a web page, the client request being received from a client device;
responsive to the client request, transmitting, by the server system, a third-party service request including a web address associated with the web page and a user identifier to an intermediate system, the third-party service request being a request for a third-party service;
processing, by the server system, a session token request received from the intermediate system, the session token request including the user identifier;
