Containers on SDDCUse Cases



bution

Containers on SDDC: Use Cases

• Modernize traditional apps• No refactoring

• Develop new 12-factor apps• App refactoring

Application Repackaging Cloud Native

• Enable developer agility• Self-service portal

Developer Sandbox




bution

Use Case Example:Developer Sandbox

Use Case Description:

• Ticketless development environment with IT governance and control

VMware Value Proposition:

• Enable developer agility on vSphere

• Efficient utilization via resource pools

• Simplified container framework deployment

• Enterprise-class registry (AD/LDAP, replication, content trust, scanning)

• Unified enterprise tooling with logging, monitoring

Customer Benefits:

• Enable developer agility

• Faster application time to market

• Docker and Kubernetes

bution

Developer Sandbox – Real-world Example

• Developer self-service with VI Admin governance

– Developer consumes resources via Docker API/CLI

• Provides developers with self-service for applications not yet in the enterprise service catalog

– Rapid prototyping

• Run a full-fledged docker engine as a ContainerVM using vSphere Integrated Containers and the Docker API/CLI

– DCH are packaged in a docker image and can be instantiated on VIC like any other container

– DCH provides command-line options to enable/disable features of the docker engine

– All DCH packages are based on PhotonOS

• Source, dockerfiles and documentation available at github.com/vmware/vic-product
