Top 5 challenges to cloud native adoption… Monitoring Security Lack of Training Cultural Challenges Complexity 0 5 10 15 20 25 30 35 40 45 Percentages https://www.cncf.io/blog/2018/08/29/cncf-survey-use-of-cloud-native-technologies-in-production-has-grown-over-200-percent/
Other Challenges • Storage (30% down from 41%) • Networking (30% down from 38%) • Reliability (17% down from 20%) • Logging (25% down from 32%) • Scaling (20% down from 24%) Technical Challenges Decrease But still Major roadblock https://www.cncf.io/blog/2018/08/29/cncf-survey-use-of-cloud-native-technologies-in-production-has-grown-over-200-percent/
Kubernetes & Cloud Native Challenges • Managing, maintaining, upgrading Kubernetes Control Plane • API Server, etcd, scheduler etc…. • Managing, maintaining, upgrading Kubernetes Data Plane • In place upgrades, deploy parallel cluster etc…. • Figuring out container networking & storage • Overlays, persistent storage etc… - it should just work • Managing Teams • How do I manage & control team access to my clusters? • Security, security, security Source: Oracle Customer Survey 2018
