'Cloud-Native' Ecosystem - Aug 2015

Publié le

Over the last several years, we’ve seen the emergence new application architecture – dubbed “cloud native” – that is highly distributed, elastic and composable with the container as the modular compute abstraction. With that, a new breed of tools has emerged to help deploy, manage and scale these applications. Cluster management, service discovery, scheduling, etc. – terms that previously were unknown or, at best, reserved for the realm of high-performance computing – are now becoming part of every IT organization’s lexicon. As the pace of innovation continues at breakneck speed, a taxonomy to help understand the elements of this new stack is helpful.

The “Cloud-Native” Ecosystem presentation is the consequence of many conversations with developers, CIOs and founders who are playing a critical role in shaping this new application paradigm. It attempts to define the discreet components of the cloud-native stack and calls out the vendors, products and projects that comprise the ecosystem.

Note, this is an ever-evolving document that’s meant to be collaborative and is by no means a hardened or exhaustive industry landscape. If you have suggestions, edits and/or know of products or companies that should be included please don’t hesitate to get in touch.

'Cloud-Native' Ecosystem - Aug 2015

  1. 1. The ‘Cloud-Native’ Ecosystem August 2015 : @lennypruss
  2. 2. • Characteristics of the “cloud-native” stack:  Containers as the modular compute building block with…  Composable, microservices-oriented application architectures and…  Dynamic, self-healing scheduling • Today Docker, CoreOS, Kubernetes (Google) and Mesosphere are leaders but there are no winners yet o We still don’t know what the components of the container stack will look like…  Distributed service discovery is still broken (etcd is not highly available)  Autonomic scheduling is promise not yet reality: Kubernetes is right abstraction, Mesos is right scheduling algos, but neither has it nailed  There are major unresolved issues around persistence, storage and security  But the biggest issue facing the ecosystem? Lack of best practices and know-how • Most of market is competing at management layer, but as we saw with virtualization and cloud: you win from the bottom up – in this paradigm that’s the orchestration/cluster management layer • Containers are still missing a “killer app” and a business case (virtualization :: consolidate IT) • With standards now emerging (Open Container Initiative, Cloud Native Foundation) we expect to see the emergence of a hardened toolchain which should unleash a second wave of innovation Key Findings and Summary
  3. 3. The “Cloud-Native” Stack – Taxonomy Physical Infrastructure Virtual Infrastructure Minimal OS Container Engine Service Discovery Orchestration: Scheduling & Cluster Management Workflow / Management Code Tools Infrastructure Programming languages, frameworks and libraries that comprise applications Code deployment pipelines, automation and configuration management frameworks, container and infrastructure management Tools which automatically run and manage jobs, containers and hosts in a cluster; often modeled after Google Borg/Omega Tools enabling an application or service to discover information about its environment and other components needed to form a larger system Specification and execution engine for operating-system-level virtualization environment for running multiple isolated Linux systems Lightweight operating system to manage compute resources necessary to deploy applications in containers Emulated physical compute, network and storage resources that are the basis for cloud- based architectures Physical servers, switches, routers and storage arrays that occupy the datacenter

  6. 6. Appendix: What are Linux Containers? Virtual machines include the application, the necessary binaries and libraries and an entire guest operating system - all of which may be tens of GBs in size Containers include the application and all of its dependencies, but share the kernel with other containers, runing as an isolated process in userspace on the host OS. Containers run on any compute substrate (laptop, bare metal, cloud) • Containers are an operating-system-level virtualization environment for running multiple isolated Linux systems on a single Linux host • Containers package a software application in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries • Benefits: • Small: hold only the application logic and dependencies needed to run so disk footprint is tiny • Fast: no CPU or I/O penalty because there is no virtualized hardware to pass through or boot • Portable: because containers are packaging format that holds an application with all of it’s dependencies and configurations it will run the same in any environment
  7. 7. Appendix: Why Do They Matter?  As every organization becomes a software organization, faster release cycles are a source of competitive advantage  “DevOps” defined by convergence of IT ops and software development to streamline deployment cycles  Continuous deployment – practice of continually shipping code to production – could be containers’ “killer app”  Microservices architecture, a development practice of writing applications as a series of modular, discrete services, has been increasingly adopted by organizations in an effort to improve speed-to-market and agility  All this is to say: containers enable organizations to write better software faster
