A look at broad industry trends and how it affects networking

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)

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

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](https://reader034.fdocuments.net/reader034/viewer/2022042723/587903ad1a28ab6f658b4737/html5/thumbnails/17.jpg)
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](https://reader034.fdocuments.net/reader034/viewer/2022042723/587903ad1a28ab6f658b4737/html5/thumbnails/19.jpg)
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)
