Game Changing: Day 2 Enterprise Data Management Tasks with VMware NSX and vRealize Network Insight

As a Staff Partner Architect at VMware, I tend to look at our platform and products through a slightly different lens than some of my colleagues. Rather than focusing solely on our feature rich product sets and platform, I take a top down approach and identify which of these features are most interesting for mission/business critical deployments in a Software-Defined Data Center (SDDC).

VMware NSX is one of those game changing technologies which should interest application owners, database architects, CIOs, and of course network IT professionals. You can think of NSX as a network hypervisor, as such NSX administrators now have the ability to abstract and reproduce a complete set of layer 2 to layer 7 networking services. The ability to abstract and reproduce layer 2 to layer 7 networking services is certainly meaningful to network operations but what does it mean to enterprise architects? Why should our customers care, and why should CIOs care?  The answer is hair-pinning. Continue reading

Demo – Extended Oracle RAC across sites with VMware NSX

Our team has been working on building solutions for NSX with Business Critical Applications around Zero trust security, application mobility, operational efficiency, increased security and more .

In a previous post I published a demo about database cloning and enforcing dynamic security policies using NSX: http://blogs.vmware.com/apps/2016/04/dynamically-enforcing-security-on-a-hot-cloned-sql-server-with-vmware-nsx.html

In this blog post we are showcasing the ability to stretch an Oracle RAC solution in an Extended Oracle RAC deployment between multi-datacenter and using VMware NSX for L2 Adjacency.

With Extended Oracle RAC , both Storage and Network virtualization needs to be deployed to provided high availability, workload Mobility, workload balancing and effective Site Maintenance between sites. Continue reading

Demo – Dynamically Enforcing Security on a Hot Cloned SQL Server with VMware NSX

VMware NSX is a software defined solution that brings the power of virtualization to network and security.VMware NSX

There are many great papers about NSX in general: for example here & here and many others, the purpose of this demo is not to dive into everything that NSX does, Instead I have focused on one capability in particular and that is the intelligent grouping of NSX Service Composer with the Distributed Firewall (DFW) and how to utilize it to make life easier for SQL DBAs and security admins, its doesn’t have to be only SQL Server, it can be any other database or application for that matter but for this demo I am focusing on SQL Server.

First, a bit of background: The NSX Service Composer allows us to create groups called “Security groups”. These Security groups can have a dynamic membership criteria that can be based on multiple factors: It can be part of the computer name of a VM, its guest OS name, the VM name, AD membership or a tag (tags are especially cool as they can be set automatically by 3rd party tools like antivirus and IPSs, but that is for a different demo)

These Security groups are than placed inside the Distributed Firewall (DFW) rules which allows us to manage thousands of entities with just a few rules and without the need to add these entities to the Security Group manually.

In the demo I have created an environment that is set with 0 trust policy, that means that everything is secured and every packet between the VMs is inspected, the inspection is done on the VMs vNIC level in an east-west micro segmentation way. That means that if a certain traffic is not defined in the DFW it is not allowed to go through.

This is something that wasn’t really possible to do before NSX

Our production app database is an SQL database and in the demo the DBA wants to hot-clone it aside for testing purposes, but obviously the cloned SQL Server needs to have some network traffic allowed to pass to it, yet it needs to be secured from everything else.

Instead of having the traditional testing FW zone with its own physical servers, I created the rules that apply to a test DBs in the DFW, created a dynamic membership Security Group, and nested that group in the rules. Now, any database server that I will clone which corresponds to the criteria will be automatically placed in the rules.  What’s really nice about this is that no traffic is going northbound to the perimeter FW because the packet inspection is done on the vNIC of the VMs (and only relevant rules to it are set on it) , no additional calls to security admins to configure the FW are needed after the first configuration has been made. This is a huge time saver , much more efficient in terms of resources (physical servers are now shared between zones) and a much more secure environment than having only a perimeter FW.
