Containers Eco-System and Use Cases

Containers is a popular technology and is being rapidly adopted in the market

•5x user growth (to ~8% of customers)

•Docker runs on 6% of monitored hosts from near zero earlier this year

•Container adoption is higher in larger companies

•Users triple number of containers in 3 months

Source: Datadog survey (7000 customers)

•2B Docker Hub Pulls

•20x growth in past year!

• A Linux container allows to run multiple applications isolated from one another on the same operating system

• Docker automates the deployment and portability of any application and all dependencies within a lightweight, editable, self-sufficient container

• Containers have the potential to disrupt and replace traditional datacenter virtualization

PortabilityPackaging Performance

APP

- Image contains all libraries needed for application

- Easy to build, share, update

- Unit of testing / distribution

- Near bare metal performance

- Minimal overhead per container

- Near zero “boot” time

- Move apps between private clouds

- Shift workloads to/from public cloud

- Easy to move through CI/CD

What is a container?

Containers bring benefits in the app development space because of their portability and flexibility• Agility in app development

• Application lifecycle management

• CI/CD and ease of deployment

• Improve business process architecture using a composition of services

• Cost reduction: • Increase DC utilization / higher

density than virtual machines• Reduce costs of virtualization

Contiv: Making Infrastructure/Solutions Ideal for containers

• Container industry is focused on creating ability to define applications through Docker Compose, Kubernetes Pod definition etc.

• As applications move from development to production, there is need to able to define and enforce infrastructure operational policies

• Contiv is creating industry thought leadership around need for infrastructure policies for containerized applications in a shared infrastructure

• Contiv provides framework and implementation to address operation intent for Infrastructure.

Contiv Addressing Enabling Infrastructure to Run Production Containerized Applications Better

• Agile - Increased speed of infrastructure provisioning• Networking: network creation, endpoint reachability convergence security policies instantiation• Storage: Storage policies for volumes as they are instantiated• Handling short lived containerized applications

• Scalable providing higher performance• Support 10x scale (when compared to VMs) for network, compute, and storage entities• Scale performance by leveraging underlying infra capabilities

• Predictable providing better reliability and easier to troubleshoot• Enable efficient resource utilization via enforce operational policies on Infrastructure• Enable application level visibility

Contiv – Open Source Project focused on Policy Based Infrastructure for Containerized Applications

• Contiv.io is an open-source project that creates a policy framework in different domains of containers

• Network Policies: Policies for Application Security, Prioritization, and Network Resource Allocation

• Network Services for Apps (Virtual or Physical Service appliances)

• Analytics/Diagnostics

• Integrates with Cisco ACI, Nexus, and UCS Solutions

• Ecosystem: Docker, Kubernetes

• Status: Beta

Contiv Networking provides policy-rich container networking that integrates with Cisco Nexus and ACI

Contiv– Best Choice for Enterprise Containerized Application Deployments• Best integration with existing infrastructure install-base, any network

topology• No topology/connectivity/feature changes to get started with containers

• Best leverage of infrastructure hardware (UCS, Nexus)• Integrated with Cisco ACI for container applications for highly scalable solutions

• Consistent behavior with variety of workloads (VM, Container, Bare-metal)• Native visibility of container workloads in network

• Value added features • Scalable Policies based approach, Multi-tenancy with telemetry and fully

automated cluster maintenance• Feature Rich Integration with Container eco-system - Docker,

• Project Mantl integrates different components of a container infrastructure (orchestration, etc.) to make it simple to deploy, also in multi DC environments

• Project Shipped integrates different tools to make it easy for developers to deploy applications on an agnostic platform

• Ecosystem: Mesosphere, Kubernetes, CloudFoundry (open-source), OpenShift, Docker

• Contiv will provide infrastructure differentiation for Shipped/Mantl

Shipped aims at creating an agnostic container experience for developers and with Contiv, provides infrastructure differentiation

Conclusion

• Containers and Micro services based applicaton architecture will likely disrupt /replace traditional data center virtualization

• Contiv provides tools necessary to maintain operational policies in a containerized infrastructure.

• IT needs to evolve to embrace Fast IT
