  1. Positioning Yourself for the Future Some technologies and trends that

    I recommend watching or learning Scott Lowe, VCDX 39 vExpert, Author, Blogger, Geek http://blog.scottlowe.org / Twitter: @scott_lowe
  2. Before going any further • Get involved! Audience participation is

    encouraged and requested. • If you use Twitter, feel free to tweet about this session (use @VMUGSydney, @MyVMUG or hashtag #VMUGSydney) • I encourage you to take photos or videos of today’s session and share them online • This presentation will be made available online after the event
  3. • In Oct 2012, I gave a presentation titled “Three

    Technologies Worth Watching or Learning” • Presentation is available online at <https://speakerdeck.com/ slowe/three-technologies-worth-watching-or-learning> • This presentation is an update to that one • Attempts to answer the question, “How can I best position myself for future trends?” Some history
  4. • Linux • Network virtualization • OS and application containers

    • RESTful APIs Some new technologies to watch/learn (2014 edition)
  5. • Popping up more and more throughout the data center

    • Serves as the basis for many products • Inexpensive solution for a variety of issues • Key things: • Pick a distribution (Ubuntu & Red Hat/CentOS seem to be most prominent) • Figure out how to do common tasks (DHCP, DNS, firewall, web server, proxy, etc.) Why Linux?
  6. • A key part of a cloud/SDDC strategy • I’m

    doing an NSX deep dive today at 3pm • Key things: • Some networking basics (learn the language) • SDN (original definition) and OpenFlow • Open vSwitch (OVS) • Network encapsulation protocols (STT, GRE/NVGRE, VXLAN) Why network virtualization?
  7. • Lightweight way of providing isolation • Two examples are

    Linux containers (LXC) and Docker • LXC primarily targeted at OS containers • Docker primarily targeted at application containers • Can provide greater scale for the right use cases • Complementary to full machine virtualization (like VMware) Why OS and application containers?
  8. Dockerfile example FROM ubuntu MAINTAINER Scott Lowe <[email protected]> # Make

    sure package repositories are correct RUN echo “deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list # Update packages and install OpenSSH RUN apt-get update RUN apt-get install -y openssh-server # Expose port and run SSH daemon EXPOSE 22 CMD [“/usr/sbin/sshd -D”]
  9. • The data center is increasingly API-driven • Public cloud

    services against which IT is being compared are API-driven (AWS, for example) • Understanding APIs helps understand how to integrate solutions • Key items: • JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) • Using cURL to interrogate an API Why RESTful APIs?
  10. JSON example { "result_count": 3, "results": [ { "_href": "/ws.v1/lswitch/3ca2d5ef-6a0f-4392-9ec1-a6645234bc55",

    "_schema": "/ws.v1/schema/LogicalSwitchConfig", "type": "LogicalSwitchConfig" }, { "_href": "/ws.v1/lswitch/81f51868-2142-48a8-93ff-ef612249e025", "_schema": "/ws.v1/schema/LogicalSwitchConfig", "type": "LogicalSwitchConfig" }, { "_href": "/ws.v1/lswitch/9fed3467-dd74-421b-ab30-7bc9bfae6248", "_schema": "/ws.v1/schema/LogicalSwitchConfig", "type": "LogicalSwitchConfig" } ] }
