Cloud Native Application

  2. 2. Disclaimer • This presentation may contain product features that are currently under development. • This overview of new technology represents no commitment from VMware to deliver these features in any generally available product. • Features are subject to change, and must not be included in contracts, purchase orders, or sales agreements of any kind. • Technical feasibility and market demand will affect final delivery. • Pricing and packaging for any new technologies or features discussed or presented have not been determined.
  3. 3. Agenda 1 Overview of Cloud-Native Applications 2 Running Containers on VMware Infrastructure 3 Introducing the VMware Photon Platform
  4. 4. 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
  5. 5. 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
  6. 6. 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
  7. 7. 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
  8. 8. 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
  9. 9. Hardware OS Kernel OS File system Userspace Container Appprocess Appprocess Appprocess Appprocess Appprocess Container Appprocess Appprocess 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
  10. 10. 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 ~# docker build my_app ~# docker push my_app ~# ~# docker pull my_app ~# docker run my_app ~#

  14. 14. 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!
  15. 15. 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 NSX VSAN vRealize vSphere vSphere Integrated Containers (Instant Clone, Project Bonneville, Photon OS)
  16. 16. 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” Forked Child Container Forked Child Container Forked Child Container Photon Parent VMware vSphere Infrastructure Virtual Docker API Shared Images

  20. 20. Introducing Photon Controller
  21. 21. Cloud-Native Platform VMware Photon Platform Photon Controller Photon Machine Photon Platform Host controller & scheduler: High scale distributed control plane, includes Lightwave Compute host: Lightweight hypervisor, based on ESX Includes Photon OS Deep integration with modern, open source frameworks & app platforms
  22. 22. Photon Platform Architecture 23 Photon Machine PhotonOS Photon Machine PhotonOS Photon Machine PhotonOS Photon API Photon Controller Clustered design delivers massive scale and high- availability. Combination of local and/or shared Photon Machine datastores.

  23. 23. 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.
  24. 24. 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.
  25. 25. Photon Controller High-Level Architecture (Long-Term) ESXi ESXi Storage / Virtual SAN NSX Best-of-breed virtualization infrastructure, capable of using off-the-shelf hardware. Multi-tenant API-driven fabric optimized for scale, churn and high-availability (not vCenter).
