5 What is a Service Container? Service Containers use virtualization technology to provide a hosting environment on Cisco routers & switches for applications which may be developed and released independent of platform release cycles Cisco and/or its affiliates. All rights reserved. Cisco Public 5

6 Use Cases for Service Containers Virtualized environment on a cisco device. Use Case Cisco Virtual Services: Work/Appliance Consolidation Example: ISR-WAAS on ISR4451-X Use Case Cisco Agents: Integral Router Features with decoupled release cycles Example: RESTFul API in the CSR1000v Use Case Signed Third Party Services: Container Hosted OnePK Applications Service Containers Network OS Container Virtual Service 2013 Cisco and/or its affiliates.

15 Terminology Virtual-Service: This refers to the container service configuration object. It is sometimes also called the Virtual Machine: (VM) or the container. Host: The IOS-XE, NXOS system software Guest: An instance of the foreign software being hosted. It is sometimes referred to as the application. OVA: The software package provided by the application writer which contains the application and metafiles used to create the hosting environment. (Open Virtualization Archive) Distribution: The complete set of software provided by the application development team. KVM: Kernel Virtual Machine LxC: Linux Container 2013 Cisco and/or its affiliates. All rights reserved. Cisco Public 15

16 IOS & Host Service IOS & Host Service Service Container Technologies KVM Description: KVM is a virtual machine emulation of the underlying hardware. KVM runs as a Type 2 hypervisor on IOS-XE. IOS/VMAN provide VM management Services. Characteristics: Isolates Guest Operating System from Host OS Takes advantage of CPU hardware extensions found on server-class processors (e.g., Intel s VT-x technology) Provides the highest level of guest/host isolation. LXC Description: This is an operating system virtualization technology (not a hypervisor) that shares the host kernel with the guest but provides isolation through namespace extensions to the Linux kernel. Characteristics: Native Performance, no device emulation or CPU specific requirements Support across Processor Architectures (MIPs, PPC, Intel) More easily allows sharing of host services/libraries into guest Host has direct visibility into resource usage and contention Guest applications run on the same OS kernel and thus there s less isolation and fault separation Application Guest Root File System Application Guest Root File System Guest OS Kernel Host OS (Linux Root File System) Host OS (Linux Kernel) Hardware Resource Host OS (Linux Root File System) Host OS (Linux Kernel) Hardware Resource 2013 Cisco and/or its affiliates.
