Microservices und Container
Donnerstag | 15. Februar 2018 | 10:00 Uhr
Man braucht die richtigen Werkzeuge, wenn man agil entwickeln und
Microservices schnell und oft ausbringen will. Das Paketieren in Containern ist
heute oft Mittel der Wahl, unterstützt durch die breite Palette an offenen
Lifecycle-Management und Orchestrierungswerkzeugen. Die umfassenden
Möglichkeiten der Oracle Cloud für vollautomatisiertes, Container-basiertes CI/CD
werden vorgestellt.

Oracle Strategie für Container-Based-Infrastruktur
• Deliver a container based capabilities that are complete, integrated and open
– Orchestration/Scheduling, CI/CD, Management/Operations, Analytics/Introspection
– With application development platform for serverless and microservices
• Based on community driven open source technology
– Investing in open source communities and foundations (Kubernetes, Docker, CNCF) via
engineering resources, code contributions & sponsorship
• Differentiated on quality of service and operational excellence
– Full, transparent management
– Deployed to Oracle Cloud Infrastructure
– Enterprise grade security, HA and governance

Oracle & Open Source und Container-Community
• Oracle’s participation in open source community
– Active Participation – Cloud Native Compute
Foundation and Kubernetes
– No forked code – straight from the source
– Continue precedence of Java, MySQL, Linux
• Lead by example
– Oracle software on Docker Store
– Kubernetes engineering in CNCF
• Innovate in open source
– Utilities like K8S installer, smith, railcar, crashcart
• Sponsor & contribute to key conferences
– DockerCon, Kubecon, CoreOS Fest, others
