Composer

VMwareNSX

The NSX service composer is one of my favorite features of NSX. I’ve never really considered myself to be lazy when it comes to doing something the right way…but I’ve never been one to overwork myself to do that. Dad always said “Work smarter, not harder”. The service composer is a combination of both. It’s a way to create multiple rules in your virtual infrastructure for items that are alike or that need to have the same type of services allowed or denied. For you Cisco guys, this is a familiar concept. Think objects and object groups on a ASA. For example, say I have a group of 6 web servers that I want to block ICMP traffic. Well that would normally mean that I would have to create 6 individual rules, one for each web server, to block this. With the service composer, however, I can create one rule. With the use of security groups and security policies, service composer makes life easy…and that doesn’t mean that you’re lazy 🙂

In this blog post, I will show you how to use the service composer to create a security policy and apply it to multiple servers.

First navigate to Networking & Security > Service Composer
