AWS as a playground
Our major concern was to ensure that nobody could solve the challenge by himself in one day, so we worked on a scenario that would require the implementation of several technical components:
We reviewed the knowledge and motivations of everyone to be sure to build 2 teams able to take up that challenge, which will be called:
The challenge’s content was finally revealed to the whole tribe the afternoon before, via an 8-page PDF document containing the instructions and the description of the architecture to implement.
With the game scheduled to begin at 9.30 am, the tribe has never been so punctual. At 9.00, everybody was gathered in the room, waiting for the « go ». Considering all the tasks to do, it was to be the start of a full thrilling day. The amazing dashboard filled with red indicator perfectly complemented the challenge’s environment.
To strengthen the team spirit, each participant received a customized T-shirt with the team’s name and logo, his trigram and a personal, funny nickname.
To meet that challenge, the « Pandas » and the « Otters » were free to organize themselves to create working groups and process the different tasks in parallel: API development, CI installation, certificates implementation, storage infrastructure, AWS infrastructure configuration...
Inspired by the DevOps’ culture, each team chose a kanban on the wall, then filled it with a backlog of the tasks to be done and with 1-hour iterations.
With 10 people by team and 5 bricks to implement, pairs naturally formed to share the tasks and define the target architecture.
Team decisions | The Cuddling Sea Otter Pups | The Laughing Red Panda Cubs |
Language | Node.js | Ruby |
Certificate | Let’s Encrypt | AWS Certificate Manager |
Object Storage | Use of S3 while waiting for the Ceph cluster to be ready | Use of S3 while waiting for the Ceph cluster to be ready |
Application packaging | Docker | Docker |
At the end of each 1-hour iteration, the team would present the progress report:
With the first performance test expected at 1 pm, they had less than 3 hours left to develop the application, publish it and deploy it using the CI on AWS.
High availability, scalability and Ceph clusters? Let’s leave that for later!
Results weren’t long to come: the « Otters » took the lead!
During each iteration, the teams were facing several kinds of difficulties. When a pair was blocked, they would ask the rest of the team for some help, and by working together as a team, ideas emerged to solve the problem.
The goal of the morning was to bring up the entire infrastructure to make all the dashboard red indicators go green thus validating the proper functioning of implemented architectures.
Quick lunch: between the last ones that need to be kicked out of the room and the first ones coming back from lunch, no more than 30 minutes had passed.
The first performance campaign initially scheduled at 1 pm was finally postponed to 2 pm in order to let the teams finish assembling the bricks. The « Otters » still had a slight advantage on the « Pandas ».
And the stressful (but not for everyone) performance campaign session could finally begin.
The stress scenario was as follows:
During the performance tests, the organizers trigger the following events:
Whereas the « Otters » were leading the race with a slight advantage for a while, the following performance campaign reversed the trend, and it was with goodwill that the « Pandas » were celebrating this event with modesty.
The tribe successfully met the challenge: by the end of the day, each team had an entirely working solution with only tiny differences.
With a ROTI of 5 on this day, the objective was reached:
In addition, here are a few verbatims of the tribe who enjoyed the whole day:
“Thank you, it was awesome. Congrats to all the OPS and to the organizers (Eric, Yann and Arnaud) who really rocked !” “Thank you guys it was really great ! Ok to do it again tomorrow ;) Big up to all the bogops !!!” “Simply exceptional. Thank you for everything, and congrats to panda team : we kicked some otters’ asses.” “Thank you to the Otters team who kicked pandas’ asses the whole day, as expected :)” “A great moment of open friendship and healthy friendly competition !” “Great day :) Thanks to the organization team (which was magical and enlightening) and to the player team.”
With a message shared several times and which still echoes: “It's awesome to learn while having fun !”
Next time, come and play with us.
And if you behave, we will disclose to you the backstage of the preparation of such a great day.
