Burro! it’s not about you, it’s about the business!

  The Donkey has a well know reputation for stubbornness, a strong sense of self-preservation, means it’s difficult to force a donkey into doing something it perceives to be dangerous. Yet, Donkeys can be very dependable, although cautious they are also, intelligent, friendly, playful, and eager to learn. (Ref: wikipedia.org/wiki/Donkey)     The Managed Service Model [...]

Use PowerCLI to mass assign tags and storage based policy management

Storage Based Policy Management (SBPM) has been around for a while, when working with storage tiers, metro clusters, or vSAN, it's either fundamental or best practice. But clicking on anything more than half a dozen vms and datastores is a bit too much hard work. Using a mix of PowerCLI and the web client I [...]

VMware Cloud on AWS – Elastic Resource Management

In my previous post, I talked about the setup of a SDDC on AWS. Now I want to focus on resource management and the scalability features Add/Remove Hosts One of the coolest features of VMC, is the ability to scale up or down (keep in mind 4 hosts is the minimum). The Add /Remove Host feature allows [...]

Why don’t we do like AWS do? – Multisite Networking

When I started playing with virtual machines, I got a real buzz at how easy it was, spin up a vm, move it between servers or storage, right click and action. I get a similar buzz from working with AWS, they make technically complex but desirable solutions look easy. For example distributing an application across [...]

VMware Services on AWS

VMware have just announced a partnership deal with AWS that will allow the running of dedicated vSphere based services directly on AWS clouds. Customers can either integrate on-premises vSphere services with AWS cloud services, or have a hybrid model of  on-prem and cloud vCenters. For example this would allow an vm running in a local datacenter to leverage [...]

VMware NSX Security Features – Who should pay for them?

One of the typical questions when considering NSX deployments is who should be the administrator?  However this is often a two horse race, between Network and Virtualization Systems Administrators. Although NSX is SDN (software defined networking), the driver behind much of what it does is due to security requirements, using vlans to segregate layer two networks, [...]

NSX – Availability and Redundancy

vSphere administrators normally have two great fears, failure of Storage and failure in the network layer, as both of these can result in 100s or 1000s of virtual machines simultaneously going off line. Software defined networking such as NSX or vShield have the potential to bring those failures even closer to home. How has NSX been architected to make it [...]

vSphere Integrated Containers – Manageability and Security

vSphere Integrated Containers. For the last few years I’ve been noting with increasing anxiety the rise of docker and the predicted invasion of the virtualized machine environment. When VMware previewed the open source Photon platform and the vSphere Integrated Container initiates I breathed a sigh of relief that they had noticed the amassing armies of [...]

Using infrastructure qualities to assess new technology

Change is the only constant. Everything changes and nothing stands still. That is especially true of technology. Many of today’s products will be outdated in a single life cycle. As new features are added at each major release products can be completely transformed within a few short years. Technology vendors pitch themselves as solution providers, [...]

Surviving a security audit

The main point of a security audit is not to try and strangle the auditor, he is just doing his job, although you might think he is there to make your life impossible.
