Agenda
1 Overview of Cloud-Native Applications
2 Running Containers on VMware Infrastructure
3 Introducing the VMware Photon Platform
Application Design is Changing
Properties of a Microservice
• Small code base
• Easy to scale, deploy and throw away
• Autonomous
• Resilient
Benefits of a Microservices Architecture
• A highly resilient, scalable and resource efficient application
• Enables smaller development teams
• Teams free to use the right languages and tools for the job
• Rapid application development
Monolithic/Layered Micro Services
What are Cloud-Native Applications?
Developer access via APIs
Microservices, not monolithic stacks
Continuous integration and deployment
App-defined Availability
Built for scale
Decoupled from infrastructure
Application
Motivation Behind Cloud-Native Applications
Software-Defined Everything
Regardless of industry, businesses increasingly rely on technology to differentiate
IT shifting from cost center to enabler of growth
Rich Customer Experience
Customers demanding enhanced engagement Third Platform: mobile, social, analytics, cloud
Speed and Agility
Improving time-to-value with DevOps, Agile New architectures to streamline workflows
New Capabilities and Priorities
Infrastructure must be dynamic, API-driven, highly scalable Small teams able to manage large fleets
Cloud-Native Architectures Less Reliant on Rich Infrastructure
Traditional App Cloud-Native App
Architecture Monolithic Microservices
Configuration Procedural Declarative
Availability Handled by infrastructure Integrated with app
Storage Centralized, redundant Scale-out object
storage and NoSQL /
key-value stores
Response Shifting demand handled
by DRS, scale-up
Scale-out,
load balanced traffic
Interface GUI, robust orchestration API/CLI preferred,
integration with
DevOps toolchain
Containers Are Aligned with Cloud-Native Architectures
• Application portability supports wide range of environments
• Automation and integration with CI/CD and DevOps workflows
• Quick to instantiate and iterate, shortening feedback loops
• Stateless nature aligns with scale-out designs
But containers are not just next-generation VMs

Linux Containers
OS-level Isolation
• Isolation at individual kernel subsystem level (e.g. filesystem, process table, etc)
• User-level process (LXC, libcontainer) orchestrates these subsystems to create a container
Existed for Many Years
Solaris Zones, FreeBSD Jails, OpenVZ
Why?
• Process isolation
• Reproducible environment
• Enables management at scale
is a “Shipping Container” for Code
Developers because …
• Frictionless deployment and maximum portability
On developer laptop:
Then on server:
That’s it!!
• A natural fit for 3rd Platform, 12 factor, microservices
• It makes DevOps much, much easier

VMware vSphere Provides Perfect Infrastructure for Containers
• Run containers alongside your existing workloads on vSphere
– Leverage proven infrastructure, skill sets, and operational processes
• Allocate resources effectively to meet SLAs
– Network services, data persistency options
• Maximize uptime with vSphere services
– HA, DRS, vMotion, SRM
• Consistent management tools
– vCenter and vRealize integration for management, monitoring, compliance
• Performance on par with bare metal – possibly better
– NUMA scheduling, hardware interrupts
You came for the virtual infrastructure… Now stay for the containers!
Unified Hybrid Platform
vSphere Integrated Containers
• Give developers the flexibility, portability and speed containers deliver
• Containers are first-class citizens direct on top of the hypervisor
• Fast container deployment (on top of VM) through VMfork
• Leverage existing investments in VMware infrastructure, people, processes and management tools
• DRS, vMotion, HA/DR
• Storage and Network Integration (VSAN and NSX)
• Virtualization brings many benefits: Security, Isolation and multiple-OS support
• Apply same isolation, data persistence, networking, management and robust service levels you have today
• No rebuilding or re-architecture required
• Full compatibility with broad ecosystem of existing tools
• No need for a separately managed Linux container host, ESXi is the container host

vSphere Integrated Containers
(Instant Clone, Project Bonneville, Photon OS)
vSphere Integrated Containers Friendly to Container Ecosystem
• A virtual Docker API endpoint backed by a pool of trusted vSphere resources
– Compatible with clients or container orchestrators like Kubernetes
– Containers run as lightweight VMs – no shared Linux kernel
• Fast, Light, and Secure
– Instant Clone
– Project Photon OS
– Lightwave enterprise-grade trust
• Currently in “Tech Preview”

A Clean-Slate Approach: Optimized for Cloud Scale
Focused Feature-Set
Purpose-built for cloud native, it provides just the features needed to provide a secure and SLA-capable infrastructure for next-gen apps.
API-first Model
Built on clean, development-friendly APIs, enabling consumption and operations to automate heavily to handle massive scale.
Scale-Out Control Plane
A scale-out control plane optimizes for the creation of 1000s of simultaneous new workloads while also delivering active-active availability of system APIs.
New Economics Enables new “pay for what you need, when you need it” consumption model that is suited for large-scale deployments with elastic and variable workload requirements.
What is Photon Controller NOT? A vCenter Replacement
• They are alternatives, targeting different sets of workloads.
• vCenter will continue to be the right platform for non-cloud native apps, even once Photon Controller is released.
• Not feature compatible.
– Photon Controller will do far fewer things, at far greater scale.
– No VM Backup, HA, FT, SRM
– No explicit placement, movement of VMs or storage (*-vMotion, *-DRS).
– Limited VM hardware settings to configure.
• Not Tool or API compatibility: New model for both workload consumption, and operations (some operational tools will apply across both, e.g. auto-deploy, OVFtool, etc.)
• No “upgrade path” from vCS.
Photon Controller High-Level Architecture (Long-Term)
