Il ruolo dello Sviluppatore
Si preoccupa di:
✅ SCRIVERE codice
✅ GESTIRE codice
✅ BUILD e TEST
✅ MONITORARE
✅RILASCIARE
Non vuole:
⛔️ GESTIRE l’infrastruttura necessaria
⛔️ RALLENTAMENTI dovuti alle complessità

Coursera Provides Online Courses to More Than
25 Million Worldwide Using AWS CodeBuild
Coursera needed a scalable
build solution that could
reduce build times for its
JavaScript web applications.
The company also wanted to
automate the process of
deploying JavaScript.
The company chose AWS
CodeBuild for its build
solution because it processes
multiple builds concurrently. It
used Amazon ECS to deploy
the JavaScript applications
and AWS CodeBuild to
automate the deployment
process.
• Reduced build times by 83%
• Runs 300–500 builds a day
• Can run multiple jobs
concurrently, so no jobs are
left waiting in the queue
• Continuous scalability for
build processing
SolutionChallenge Benefits
We can run 50 or 60 jobs in parallel, and the build
time is only the time it takes for the longest
application to build.
