The Journey to Cloud Native – A case study with mantl.io

• Key Concepts

• Open Source Container Stack: Mantl

• Developer Experience: Shipped

• Key Benefits

• Case Study: Webex Mantl adoption

Outline

Key Concepts

Pets vs. Cows

IT treats the servers as a Pet. A lot

of care and time is spent to ensure

the server is running.

IT treats the servers as Cows. Even if a

Cow dies is not important. They will be

replaced, the important thing is that the

“heard” survives.

If your servers have names … you are treating them as Pets!

Bimodal IT: Mode 1 vs. Mode 2

Containers vs. Hypervisors

Containers are segregate space in the OS kernel, Docker makes

those spaces accessible using API

Developer Experience Required:Shipped and Mantl

• Interface for cloud native development.

• Developer/Operations friendly.

• Easy-to-adopt, easy-to-use.

• Builds a ‘Developer-Experience / PaaS layer’ on top of our Mantl Container stack.

Case Study: Webex

• Managing VMWare deployments is becoming increasing complex• Distributed software architecture

• Limited automation (manual installs)

• Manual VM allocation/Network Configurations

• Very long deployment process• Compute CPU and Memory requirements documentation

• Each functional program follows this process resulting in low resource utilization

• Desire to achieve better resource allocation

• Drive to more efficient orchestration and availability/assurance of services

Drivers for Cloud Native Project

• Global Service Discovery

• Flexibility with Load Balancer options (deep integration)

• Require RBAC and tenant security capabilities

• Tenant Monitoring, Host Metrics and Logs plus Events

• IP per container on Mesos/Marathon

• Global service deployments synchronized

• Support of the cloud native components
