Hi!
We built this challenge to get to know you better by understanding your thought processes and methodologies.
This challenge is divided into 2 non-sequential parts, Planning and Execution.
Both parts will include detailed instructions on what to do and how to do it.
We're building MultiVAC, a multi-purpose self-adjusting and self-correcting computer that will help us understand how to reverse the universe's entropy.
Of course, we're at the very early stages, and as such, we're starting with the bare minimum. Our MultiVAC is currently in the form of a single application that uses a web api through http with a limited number of endpoints.
There are several actions MultiVAC can perform, and answer only one question.
Question:
* How can the entropy of the universe be reveserd?
Actions:
* Acquire more data.
* Process data.
App Architecture
* Flask Server
* Workers Machines
* Redis Server
* MongoDB
Endpoint mapping
- Question
GET /multivac
- Acquire more data
POST /multivac/data
body params:
data: String
To run MultiVAC do:
python manage.py runserver
python manage.py worker
Multivac needs to learn until it provides a meaningful answer to our question.
To test it do as follows:
- Invoke the
GET /multivacendpoint and check if MultiVAC is able to answer - If MultiVAC is not giving you a propper answer, you need to feed it with more data and make it process it.
- To feed data into MultiVAC invoke
POST /multivac/dataand pass data to answer the question. - While MultiVAC processes data asynchronously, try to keep question it a couple of times to see if it can answer back. If not, repeat the whole process and feed more data into it.
Describe the deployment architecture and how you would implement it. Please mention what measure would you take for.
- Security
- Scalability
- Logging
- Monitoring
- Automation
For this part you need to request ssh for a machine. Please do that before we start.
Write the necessary scripts for deployment for this APP. Note this can be a single machine deployment, no concerns with scalability are necessary. You should do so using Ansible and Fabric. If you have no experience with these tools but have experience with equivalent ones, please use the other tools.
Set up a continuous integration system that runs the project tests after each commit and displaying on github the status of the build (Preferably use Jenkins).
Endpoint /zzz/ has a bug. Tell us exactly what the problem is, and for extra credit try to fix it.
