This project was designed to operate as a Kahoot clone although the front-end never got completed by the other member of the pair (This was written in React).
|
||||
</p>
|
||||
<p>
|
||||
This was created in a pair as part of the Cloud Computing module at City, University of London. It was built for use using google cloud and therefore
|
||||
uses many Google Cloud Platform Technologies including:
|
||||
<ul>
|
||||
<li>Compute Engine - For VM runners with master or application servers (And a relay to a database instance).</li>
|
||||
<li>Instance Groups - Contain 1 instance each and allow for use within a load-balancer.</li>
|
||||
<li>Health Checks - Used to check the status of the servers on each VM for load-balancer routing management.</li>
|
||||
<li>Firewall Rules - Secure compute instance ports via the use of tags.</li>
|
||||
<li>VPC Subnets - Reduced to 1 as no other regions needed.</li>
|
||||
<li>VPC Network Peering - Connects to another VPC that has a relay VM that connects to a Cloud SQL database - allows for funding to be shared by both members of the pair.</li>
|
||||
<li>Extra Service Account - Used by the master server to check instance status and manage running state spinning down VMs when un-needed and therefore saving money.</li>
|
||||
<li>OAuth Consent for Google Sign-in - Allows for Google Accounts to be used for authentication.</li>
|
||||
<li>Cloud Storage Bucket - Accessible by the public and is used for the static resources of the front-end.</li>
|
||||
<li>Load Balancer - Muxes connections for the backend instances against access from the rest of the internet.</li>
|
||||
<li>SSL Certificate - Used for the load balancer to allow for secure connections by users.</li>
|
||||
<li>Cloud SQL - MariaDB is used and is fully managed by the Google Cloud Platform.</li>
|
||||
</ul>

The communication protocol uses JSON packets passed either through a WebSocket connection or a REST based protocol that polls the server for data while sending the queued packets.
|
||||
The REST connection is used as a fallback system where WebSockets do not work; in addition, a REST connection is made to the master server to first work out which app server has
|
||||
the least load, once found, this is sent back to the client where the client will then attempt a WebSocket connection and, on failure, a REST session is created (A key is returned
|
||||
which is then used as a parameter in subsequent communications). In the event there is no more capacity, a service unavailable error is sent and a new VM will be spun up, in the case
|
||||
that any are left. The source code for this library can be found at <a href="https://github.com/Captain-ALM/gc-c-com">https://github.com/Captain-ALM/gc-c-com</a> and the master server source
|
||||
code can be found at <a href="https://github.com/Captain-ALM/gc-c-master-srv">https://github.com/Captain-ALM/gc-c-master-srv</a>.

The main game loop was supposed to allow user generated quizzes once logged in along-side allowing for public quizzes that could be used and copied by other users.
|
||||
Only logged in users could start games where any user - both logged in or not - could join and answer questions within a set amount of time, with the person answering
|
||||
the fastest getting more points than people who answer later. The system would also have a leaderboard shown at the end of each question; it was also designed to recover
|
||||
from crashes and resume from the last question executed. The source code for the app server can be found at <a href="https://github.com/Captain-ALM/gc-c-app-srv">
|
||||
https://github.com/Captain-ALM/gc-c-app-srv</a> where all this functionality does exist in the backend.
|
||||
</p>
|
||||
<p>
|
||||
The database system contains tables including:
|
||||
<ul>
|
||||
<li>Servers - Contains App-Server sub-URLs and the time of the last successful uptime check by the master server.</li>
|
||||
<li>Game - Contains a list of active games which are associated with a specific App-Server and Quiz.</li>
|
||||
<li>Guest - Contains a list of guests against the game they are connected with along side their nickname</li>
|
||||
<li>Quiz - Contains the quiz data, associated with a user who is the owner.</li>
|
||||
<li>User - Contains the user email and token hash for login, null when no active session is available.</li>
|
||||
</ul>
|
||||
More metadata of other required fields in each table also exists but has not been stated here; the source code is available at <a href="https://github.com/Captain-ALM/gc-c-db">https://github.com/Captain-ALM/gc-c-db</a>.
