Where We’re Headed and Where NSX Fits In

A look at broad industry trends and how it affects networking

Before we begin

• Please get involved! Feel free to ask questions, share your experience, or contribute your viewpoint.

• Feel free to take pictures, record videos, or post social media updates (use #ScottishVMUG or @ScottishVMUG)

• Out of courtesy to others, please silence your electronics • This presentation will be available after the event

It really all boils down to this

• It’s about helping your organization get through this cycle faster

So what are some trends that have evolved as a result?

Why DevOps?

• DevOps rose out of a need to eliminate delays and problems in deploying software

• DevOps != Automation • It’s primarily about culture and process (automating a broken process just

gives you an automated broken process) • Automation is an important part of DevOps methodologies

Why cloud computing?

• Faster “mean time until I can start getting work done” • Self-service infrastructure without a ticket • No more waiting on servers or VMs or networking or security

• “Unlimited capacity” (from the perspective of the consumer) • Automation is pretty much a necessity (especially from the operator’s

perspective)

Page 14: Where We're Headed and Where NSX Fits In

Why Docker?

• Makes it super-easy to deploy applications just about anywhere • Docker advocates a “single process per container model” • That naturally leads toward a microservices-based architecture

• An application is decomposed into smaller, more focused services • 1 application = many services, 1 service = multiple containers

• Manual operations in a microservices-based architecture simply don’t cut it

Page 16: Where We're Headed and Where NSX Fits In

Why Kubernetes?• Kubernetes is aimed at orchestrating containers to build applications using a

microservices-based architecture • A Pod is a group of containers • Pods are presented to the outside world as Services • Services make up applications (microservices-based architecture)

• Heavily leverages load balancing as a key element (the “Service” is a load-balanced VIP that services a group of pods)

• Manually configuring networking isn’t going to work for Kubernetes

Page 17: Where We're Headed and Where NSX Fits In

The “TL;DR” is this

• Microservices-based architectures mean more endpoints (sometimes dramatically more)

• Container orchestration tools mean endpoints being created and/or destroyed in automated fashion

• Cloud computing models means logical network constructs being created and destroyed on the fly

• Security is needed in all these cases • This simply can’t be done without some form of network automation

So where does NSX fit into all this?

Page 19: Where We're Headed and Where NSX Fits In

VMware NSX enables network automation• Supports the use cases we’ve described here

• Private cloud use cases (via vRA or OpenStack) • Public cloud use cases (demonstrated at VMworld 2015) • Microservices-based architectures with Docker (demonstrated at VMworld

2015) • Provides the distributed network services needed (switching, routing,

firewalling, load balancing) • Hardware-agnostic (only requires IP connectivity)
