How to organize system scaling if you have a thousand developers, each of whom has created from one to two unique applications?

When scaling a system with a thousand developers, each having created one or two unique applications, it is important to organize infrastructure and processes to ensure manageability, standardization, and automation.

Main approaches:

1. Modularity and microservices — divide applications into independent services with clearly defined APIs.
2. Centralized version and dependency management — use package management systems and repositories (e.g., Nexus, Artifactory).
3. Automation of CI/CD — set up build, testing, and deployment pipelines for each application using templates and infrastructure as code.
4. Organization of teams and processes — implement coding standards, reviews, documentation, and a task management system.
5. Cloud infrastructure and orchestration — use Kubernetes or similar platforms for container management and scaling.
6. Monitoring and logging — centralize metrics and log collection for quick problem detection.

Thus, scaling is achieved through standardization, automation, and the use of modern infrastructure and process management tools.
