● IT-Ops: perceived trade-off between throughput and stability
● N. Forgsgren, J. Humble [1]: positive correlation
– Survey among 7522 IT profs from dev, ops and devops depts.
● Reducing size of changesets
● Microservices:
– One failed deployment does not necessarily affect the entire system.
– Trade-off: distributed system → loss of determinism.
– Fill the gap: failure-tolerance
