The document discusses the creation of CI/CD infrastructure for open-source projects by Denis Soldatov, highlighting the importance of speed, openness, and control throughout the process. It covers various tools used, such as Travis CI and GitLab CI, as well as the costs associated with dedicated servers for Linux, Windows, and macOS. The overall goal is to achieve a fast and robust implementation while maintaining licensed purity and supporting distributed teams.

the high speed of assembly and testing
support for distributed teams
openness of process
cross-platform
the convenience of control during all stages
the licensed purity
What was required?

3. #paritytech
GitHub+Travis CI
assembly timeout
time limits
support for Linux + MacOS only
What was going on?

9. #paritytech
The cost of rent dedicated linux servers ~ 60 $ per
month - 1 server.
The cost of renting Windows and MacOS ~ $ 100 per
month - 1 server with licensed software and licensed
hardware.
What's the price?

10. #paritytech
1. Flexible confguration and scalability.
2. Painless expansion during creation of new projects
Perspective

11. #paritytech
our assembly infrastructure expenses are about $500
a month
quicker assembly
cross-platform
license purity of assembly
support for distributed teams
CD/CI control "in one window"
What was received?
