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

Host Operating System
cgroups Hypervisor

Containers are segregate space in the OS kernel, Docker makes
those spaces accessible using API

Hypervisors enable multiple Guest OS’s onto a single host,

• An open source, end to end, integrated stack for running container workloads. Including Deployment automation & assurance.
• Pluggable, designed to grow into a platform for application and data services.

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
