Powered API Governance

2. The era of platform businesses
Softwares are transforming to platforms
Growing partners means growing APIs
Partners 📈 issues 📈 governance 📉

3. Monitoring the API platform
Logging
Alarms & Alerts
Usage reports
API security tools

4. A hidden problem in all API platforms
Partners pivot in use cases of APIs can cause:
● Lengthy investigation
● Long engagements
● Tough negotiation
● Shutting down of API accesses

5. Poorly governed vs. well governed
Poorly governed platforms:
● End users’ complaints
● Partners’ self-reporting/self-policing
● Just wait for incidents to happen
Well governed platforms:
● Engineers audit
● Sales / partnership team check in
● Mandated self-reporting for new use cases

7. What kind of
problem is this?
Anomaly detection?
Categorisation!

8. Clustering analysis
Unsupervised learning
How similar are datasets
Metadata of APIs
Human needs to tweak
