1、Orlando,FLOctober 69IBM TechXchange 2025Leveraging Cloud-Native Capabilities with Kubernetes and ContainersSession 2142Next-Gen Informix:Agenda Introduction to Containers Kubernetes key concepts Kubernetes benefits Informix ContainersContainer Technology Unlike a VM,containers virtualize just the OS

2、 Kernel and run with minimal overhead Allows more services to run on a single system compared to multiple VMs Faster startup Contains all prerequisite packages and configurations Avoids conflicts with the host OS and packages Easily run multiple instances of the container without conflictsKubernetes

3、 Kubernetes views the world as a collection of services and resources Service Applications are deployed as“pods”They contain one or more containers interconnected to create the service Services are intended to scale horizontally by adding more pods Manages pods across one or many systems/nodes Some

4、services maintain a persistent state,while others do not Distributed storage systems for replicating persistent volumes across clusters in different regions.Service InternalsServices at a minimum have a statefulset or deployment definition.Several other kubernetes objects may also be created includi
