Veeam Backup & Replication – Part 1 – Building Replication Capabilities

Reading Time: 7 minutes

Just like the time I witnessed my first ever vMotion, seeing Veeam replication in the wild had a similar effect. As its name suggests, Veeam Backup & Replication is about more than just backups and offers customers rather neat replication functionality.

This article discusses Veeam Backup & Replication v10 offsite replication jobs. We also protect a business-critical virtual machine by replicating it to a secondary site. In Part 2 (Veeam Backup & Replication – Part 2 – Recovery From Failover), we will migrate the VM’s live operations to the secondary site before reviewing the available failback options.

VMware vRealize Network Insight (vRNI) – Part 6 – Importing Recommended Firewall Rules into NSX-T via Python Script

Reading Time: 5 minutes

As the holiday season is almost upon us (just two days), why not finish with one final article in my vRNI series and an article that will likely finalise my blog posts for the year.

In my previous article (VMware vRealize Network Insight (vRNI) – Part 5 – Data Flow Analysis & Micro-Segmentation), we analysed collected data flows in vRNI to manually micro-segment an application utilising the VMware NSX-T Distributed Firewall (DFW). However, what if we want to automate this process? After all, applications that require a small number of firewall rules (such as the application used in the previous article) are rare.

This article looks at Martijn Smit‘s great script, which imports vRNI recommended firewall rules into VMware NSX-T Data Center via a Python script.

VMware vRealize Network Insight (vRNI) – Part 5 – Data Flow Analysis & Micro-Segmentation

Reading Time: 6 minutes

In the previous articles of this series, we covered the installation (VMware vRealize Network Insight (vRNI) – Part 1 – Installation) and configuration (VMware vRealize Network Insight (vRNI) – Part 2 – Configuration) of vRealize Network Insight, before integrating vRNI with Microsoft Active Directory via LDAP (VMware vRealize Network Insight (vRNI) – Part 3 – Identity & Access Management via LDAP).

In the most recent article (VMware vRealize Network Insight (vRNI) – Part 4 – Application Discovery), we delved into application discovery. We defined four applications via several options – manual creation of an application, as well as automated discovery based on vSphere Tags/Custom Attributes and VM naming conventions.

In this final article of the series, we will explore and analyse the collected data flows of one of the previously defined applications. The goal here is to identify all valid traffic flows required to secure the application utilising the NSX-T Distributed Firewall (DFW). My friends, today we look at micro-segmentation.

VMware vRealize Network Insight (vRNI) – Part 4 – Application Discovery

Reading Time: 9 minutes

In the previous articles in this series, we covered the installation (VMware vRealize Network Insight (vRNI) – Part 1 – Installation) and configuration (VMware vRealize Network Insight (vRNI) – Part 2 – Configuration) of vRealize Network Insight, before integrating vRNI with Microsoft Active Directory via LDAP (VMware vRealize Network Insight (vRNI) – Part 3 – Identity & Access Management via LDAP).

In this article, we will dive a little deeper and begin looking at how we can define our applications and, in Part 5 (VMware vRealize Network Insight (vRNI) – Part 5 – Data Flow Analysis & Micro-Segmentation), begin analysing the collected data flows to implement micro-segmentation via the NSX-T Distributed Firewall.

Veeam Certified Engineer (VMCE)

Reading Time: 4 minutes

This one has been a long-time coming. I’ve been using Veeam Backup & Replication and Veeam ONE since 2014 and, in anger, since v8.0. I’ve designed, deployed, and managed Veeam solutions; however, I’ve never gotten around to obtaining any Veeam certifications.

If you’ve ever met me in person, I’ve likely told you how much I love the Veeam Availability Suite and how cool it is that Veeam keeps cramming-in so many awesome features with every release. Despite so many great features, Veeam still retains the ability to keep things simple, and I’m a fan of keeping things simple.

VMware vExpert 2021 Applications are Open!

Reading Time: 4 minutes

Don’t miss out on the opportunity, be sure to apply before January 9th, 2021. The vExpert awards will be announced on February 19th, be a part of the announcement!

What is the vExpert Program?

The vExpert Program is simply about giving back to the community beyond your day job. It isn’t a certification, and it isn’t focused on certifications, and neither does it relate to how much you know about VMware technology.

Patch VMware vSphere Host via ESXCLI

Reading Time: 2 minutes

There may be some scenarios where you will need to patch a vSphere Host manually. Maybe the host is air-gapped for security purposes, or maybe the host is simply a standalone ESXi Server and isn’t connected to a vCenter Server.

Patching the host is a simple enough exercise, and in this article, I detail both the implementation and validation steps.

Upgrading VMware NSX-T Data Center to 3.1

Reading Time: 7 minutes

With the recent announcement and general availability of VMware NSX-T Data Center 3.1 on Friday 30th October 2020, we have a number of enhancements, new features, and functionality. The new features and functionality can be seen in a previous post (VMware NSX-T 3.1.0 Release Announcement), however, I realise I’ve never discussed the upgrade procedure itself.

Upgrading NSX-T Data Center couldn’t be easier. Yes, there are some disruptive elements, however, if your NSX-T design has redundancy built-in, we aren’t talking much. Upgrading the edge and transport nodes is as simple as you can imagine, as is the process of upgrading the NSX Managers themselves and, in this article, I cover the process from start to finish.
