Production Application Architecture
Contents
CI/CD Pipeline
Continuous Integration and Continuous Deployment
- Ensures our code goes from the repository (i.e. version control) through a series of tests and pipeline checks to a production environment without manual intervention.
- i.e. Github Actions, Jenkins, etc.
Load Balancers
- Allows us to evenly distribute user requests across multiple servers
- i.e. Nginx, Traefik, Caddy, etc.
External Storage
- Running in a different server, connected over a network
- i.e. PostgresQL, MySQL, MongoDB, S3, Cloud Storage, etc.
Logging and Monitoring
- Keeps and eye on every microinteraction and/or store logs for analysis
- It is standard practice to store logs on external services, outside of our primary production server
- i.e. Sentry, Prometheus, Kibana, etc.
Alerting
- Typically connected to our logging/monitoring systems
- Alerts us and/or users about issues, errors, etc.
Safe Environments
- If possible; never debug or test directly in production environments
- We typically have a development/staging environment to test code or debug production issues.
