72. @XebiconFR @Horgix 72 #Xebicon18 Summary - Immutable infrastructure ▼ Build immutable images ▼ Do not change anything at runtime ▼ Pass these images across environments ▼ Appropriate tooling makes it easier Bonus points: ▼ Fiability ▼ Deployment speed

74. @XebiconFR @Horgix 74 #Xebicon18 Logs
75. @XebiconFR @Horgix 75 #Xebicon18 Summary - Log centralization ▼ Do not store anything on instances ▼ Ship logs & index them ▼ Non-structured document store Bonus points: ▼ Dashboard / search ▼ Retention policy
