Symfony e micro (non così tanto) services
0 likes724 views
The document discusses microservices and splitting a web application into smaller independent services. It provides examples of how a web application could be split into services for the main web, mobile, community, ads, images, and comments. It describes advantages of smaller services including being easier to maintain, deploy, and test in isolation. Challenges of microservices like service interaction, failures, and maintaining backwards compatibility are also covered.

- 16. micro vs macro
- 17. How many ways can you split an app?
- 19. Web: the main web (sf1) Mobile: mobile version (sf components) Vxl: community site (sf2 v2.8)

- 55. What if you are removing an endpoint?
- 56. What if you are adding an endpoint?
- 57. What if you are modifying an endpoint?
- 58. Maintenance
- 59. n smaller app to keep updated
- 60. MicroKernelTrait
- 61. Testing
- 62. Test a service in isolation
