vRA and NSX – Part 3, Security Groups and Policies

Automation, NSX, Tech200, VMware, vRA3 Comments

Introduction

Recapping Part 2 of this series: We staged a number of NSX Logical Switches to be consumed by vRA machines as External Networks. vRA collects and identifies these networks as traditional [vSphere] Network Paths and allows them to be wired for consumption in the Converged Blueprint (CBP) designer as needed (or using custom properties, but that’s beyond this post). Logical Switches can be created for a consumption-only model, automatically created per Deployment when using On-Demand services, or some combination of these.

Moving on…

Similar to it’s relationship with NSX Logical Switches, vRA provides both consumption-based and dynamic security services to deliver a number of use cases leveraging NSX Security Groups and Security Policies.

A Security Group defines — and logically groups — the objects you want to protect (e.g. virtual machines) and the policies that protect them (via a security policy). Group membership can be static or dynamic (e.g. based on logical naming, containers, tags, or as members of other security groups). Pre-created security groups are collected by vRA endpoint inventory and consumed as Existing Security Groups (SG) within the Converged Blueprint designer. These security groups may ultimately contain a combination of unmanaged vSphere VMs and vRA-managed machines.

vra7-327vRA also supports On-Demand Security Groups (ODSG) within CBP, which requires the use of an existing Security Policy.…

vRA and NSX – Part 2, Staging Logical Networks

Automation, NSX, Tech200, VMware, vRA3 Comments

Introduction

A logical switch emulates a traditional network switch by creating logical networks that can be used to connected one or more vnics of a virtual machine to the corresponding logical network. In an NSX environment, logical switches are directly mapped to an available Transport Zone (VXLAN) and is stretched across all hosts and clustered configured with that VXLAN. Similarly, a Universal Logical Switch is deployed when used with Universal Transport Zones and can be stretched across hosts, clusters, and even vCenters. Logical switches are typically created and managed using the vSphere Web Client. Once created, machines can be logically wired to them for connectivity to other machines and/or upstream services (e.g. NSX Edge Services Gateway or Distributed Logical Router…or anything else wired to the resulting logical network). Thanks to the power of NSX, these networks can be spun up rapidly (albeit statically) and exist exclusively in the virtualization layer, saving countless management cycles and associated overhead (+ cost).

As you are well versed by now, NSX delivers the critical services needed for a modern network infrastructure while lifecycle automation of network and security services — from provisioning to decommissions (and everything in between) — are defined by the automation layer.…

vRA and NSX – Intro to Network and Security Automation

Automation, NSX, Tech200, VMware4 Comments

Network and security automation — and specifically the use of on-demand services — will continue to play a more significant role as NSX (and network virtualization in general) continues to become more and more prominent. Customers are still trying to understand the impacts of app-centric networking and whether or not they’re ready to hand these critical services to automation tools. There’s a perception that automation reduces control and/or visibility into networking and security services that traditionally involve a ton of ownership, red tape, and several siloed personalities that love to hear their own voice (I used to be one!). Plus, there are personal domains and certifications to protect!

Once these folks realize vRA + NSX will provide greater control, more governance, and better visibility than they’ve ever had before, heads tend to deflate a bit. NSX adoption is on a rocketship and its benefits are resonating with traditional network silos and modern shops alike. As adoption (and resulting trust) continues to grow within an enterprise, the second part of the equation — automation — become the obvious next step for streamlining network and security services, often getting kicked off with two wonderful words: now what? Enter vRealize Automation.

For its part, vRA is designed to bridge the gap between a pure consumption model and on-demand everything.…

vRA and NSX – Part 1, vSphere Prep

Automation, Install Guide, NSX, Tech200, VMware, vRA1 Comment

Introduction

There are a few prerequisite steps to complete on the vSphere and NSX side before vRA can be configured to consume its services or deliver on-demand networking and security. In Part 1 of this series, we will use the vSphere Web Client to review the NSX baseline deployment and add the necessary configurations for staging. What is configured here will depend on the desired objectives and use cases…I’ll cover minimum requirements.

Note: These steps assume you have already deployed NSX Manager, registered NSX with vSphere, and prepared hosts / clusters per best practice.

Objectives:

  • Review NSX deployment in vSphere to ensure prerequisites are in tact
  • Validate Logical Network / VXLAN configuration

As mentioned previously, this guide assumes a basic NSX deployment has been completed. This section will review the lab configuration and validate NSX has been properly deployed and configured.

1.  Log in the vSphere Web Client.

2.  Navigate to Networking & Security to review the existing NSX deployment configuration.

3.  Select Installation in the Networking & Security pane.

4.  In the Management tab, verify that at least one primary NSX Manager is available and at least one NSX Controller Node has been deployed (with status: Connected):

5.  In the Host Preparation tab, expand the target clusters and ensure Installation status, Firewall, and VXLAN are all showing a green check mark:

In this example, there are two configured clusters — Cloud Cluster and Mgmt Cluster.

vRA and NSX Integration Series

Automation, NSX, Tech200, VMware, vRA7 Comments

It should be no surprise that VMware is putting a lot of time and energy around the benefits of vRealize Automation and NSX. The #BetterTogether campaign has taken off and just about anyone touching either of these solutions should be able to articulate that message by now. I’ve been focusing on the integrations between vRA and NSX partly because it’s within my charter, but primarily due to being huge believer in the transformative nature of the technology behind it. Whether at a VMUG, in a briefing, building internal content, or in my home office as my puppy, Millie, begs to go out and play just as I start recording a video (it’s like clockwork!), this has easily become one of my favorite topics.

While the benefits are easily articulated and demos [usually] go off without a hitch, much of the feedback I get suggests there’s a perceived complexity with the integration. “Not so!”, says I. While complex is a relative term, integrating vRA and NSX doesn’t have to be, especially if you have a basic understanding of the two solutions individually. Although I will agree on at least one thing — while documentation is generally getting better, there’s still a major gap in prescribed [how-to] content.…

Adding a Network Selection Drop-Down in vRA 7

Automation, Tech200, VMware, vRA14 Comments

Ever since the early days of vCAC, customers have needed the ability to provide a variety of additional control options to vRealize Automation’s self-service consumer. I’m specifically referring to inputs and selection options that are made available to the consumer during request time. Some of the most common examples include fields for plain text input, drop-down menus, checkboxes, value lists, and text descriptors. The input or selection can be basic information or used for downstream processing during machine provisioning.

Custom Properties

There are hundreds (thousands?) of use cases and unique requirements that make it just about impossible for VMware to deliver every option as an out of the box. function. Instead, vRealize Automation (vRA) leverages Custom Properties to provide a quick-n-easy way to control many aspects of machine provisioning. Custom properties can be used across much of vRA’s configuration constructs, including Blueprints, Business Groups, Compute Resources, Reservations, and Endpoints (in that order of precedence). Custom properties are a core component of vRA’s massive extensibility engine and are often used in collaboration with the Property Dictionary, Property Groups, vRealize Orchestrator (via workflow stubs), and the new Event Broker. If you’re unfamiliar with custom properties and these concepts, be sure to read the documentation.…

vRA and NSX – Using Baseline Security Groups

Automation, NSX, VMware, vRA2 Comments

vRA and NSX came together back when vRA (a.k.a. vCAC) 6.0 was released, just as VMware was transitioning from vCNS to NSX. In vRA 6.x, inventory-collected security groups must be selected (checked) per Reservation prior to being available for consumption by a multi-machine blueprint (and only MMBP’s support NSX in vRA 6.x). As I’ve highlighted several times before, the latest release of vRealize Automation (7.x) delivers deeper integrations with NSX and unified service authoring capabilities to make delivering application-centric networks the new norm. See this post for how vRA and NSX are better together…I won’t repeat those details here.

With vRA 7’s deeper integration and broader use cases, one hugely powerful feature is the ability to incorporate one or more NSX Security Groups — either Pre-Existing or On-Demand — into your service design using the new Converged Blueprint Designer (CBP). You simply drag-and-drop the security group right on to the unified canvas and bind it to the desired machine components…

As a result, the provisioned machines are automatically added to the security group (Existing Security Group) or a new security group is dynamically created and bound to an existing security policy at request (On-Demand Security Group).…
