IBM Cloud Private (Kubernetes)

19. IBM Cloud Kubernetes Service (public)
As a certified K8s provider, IBM Cloud Kubernetes Service provides intelligent scheduling,
self-healing, horizontal scaling, service discovery & load balancing, automated rollouts and
rollbacks, and secret and configuration management..
 Simplified cluster management
 Security and isolation is built in, not
bolted on
 Cloud and Watson services at your
fingertips

Helm Charts
• Helm is the open standard for Application Packaging and Deployment for
Kubernetes
• Helm charts automate the deployment of resources and prereqs including
locations of Docker images

22. ICP
Microclimate Local or
ICP
Option for 3rd Party
LEGEND:
IBM Microclimate
Applications are run in containers from day one and can be delivered into production on
Kubernetes through an automated DevOps pipeline using Jenkins. Microclimate can be
installed locally or on IBM Cloud Private.

23. WAS lift-and-shift

24. 24
Lift and shift intro
Advantages of tWAS ND lift-and-shift:
• Leverage administrative skills (experienced staff)
• Leverage operational artifacts (legacy scripts)
• Speed up provisioning of new topologies
• Assisted migration and version upgrade
• Cloud services augmentation (Watson, integrated logging, etc)
• Enables the “strangler pattern”

Multi Tenant or Single Tenant
Deploy WAS for IBM Cloud VM on
private bare-metal hardware in which
the physical cores, memory, and
storage is isolated to one customer Intelligent workload placement, VPN,
firewall, DirectLink high speed
connection up to 10Gps, & Softlayer
VLAN spanning to expand to
additional customer solutions
