Pets, Cattle, Ants Pets vs cattle as an analogy to manage IT assets and cloud infrastructure is a decade old. Even before this observation bacame commonplace, this is something that I’d seen first-hand. When I came into the IT industry, I was often supporting assets named after Knights of the Round Table, Lord of the Rings or Star Wars. Over the past two decades that’s changed to devices named after site locations and functions to… Read More »Pets, Cattle, Ants and a Lone Wolf
Cloud Migration Value Creation I recently read an excellent post by Bill Hunt titled Cloudbusting. In this article Bill outlines and challenges some of the myths of cloud computing as he sees it from his federal role. Bill is a contributor to the 2019 Federal Cloud Computing Strategy, “Cloud Smart”, which introduced a subtle change to strategy in this sector by advocating not for a ‘cloud first’ (which is often translated as cloud only) but… Read More »Cloud Migration Value Creation
What is the limit on how many virtual machines that can be deployed at once? This came up in conversation, where we were considering where to place template storage and what the implications might be behind various choices. which leads to… Limits on Simultaneous Migrations The answer for how many virtual machines can be deployed at once, is closely coupled with the limits on simultaneous migrations. This is because simply put the operations are very… Read More »What is the limit on how many virtual machines that can be deployed at once?
Following on the migration theme just recently, I’ve had a lot of queries over the past month related to VMware HCX licensing, so thought I’d pull this post together for reference. Remind me what is HCX again? VMware Hybrid Cloud Extension (HCX), in its own words is: “an application mobility platform, simplifies application migration, rebalances workloads and optimizes disaster recovery across data centers and clouds. HCX enables high-performance, large-scale app mobility across VMware vSphere and… Read More »VMware HCX Licensing
How should I migrate VMware virtual machines between VMware data centres? This is a question I got asked just before I broke for the festive period. In previous posts I’ve covered how to work around some of the most common issues that I see, providing mechanisms to help with Application Discovery and Network Mapping. There are always nuances with any large scale migrations so with any migration the true consultative answer to this question is… Read More »How should I migrate VMware virtual machines between VMware data centres?
IDS and IPS in NSX-T IDS/IPS IDS stands for Intrusion Detection System and IPS stands for Intrusion Prevention System. It is what is says on the tin, it protects your environment from an attack. IDS is a system that monitors the traffic in case of an attack and In the event of this IPS will block the network traffic. In the newest release of NSX-T which was 3.0 this came with IDS with IPS following… Read More »IDS and IPS in NSX-T
Import Azure Rate Card to vROPs I’ve been working with a customer over the last day or so to import their Azure cost information (or Azure rate card) into vROPs so that they can run a what-if analysis to plan a migration to the public cloud. Within vROPs we have the option to upload our public cloud rate cards into the service, so the the data that is provided from the service reflects the actual… Read More »Import Azure Rate Card to vROPs
How to get the available Azure VM sizes with – Get-AzureRmVmSize I was recently working with a customer who was struggling to get a list of available Azure VM sizes for the locations he wanted to deploy Az IaaS VMs. Whilst I work mainly with VMware technologies a customer is a customer, so I was more than happy to help. PowerShell As luck would have it there is a PowerShell module to provide just the… Read More »How to get the available Azure VM sizes with – Get-AzureRmVMSize
Simple Network Mapping In an earlier post I demonstrated how you could use a very simple toolset such as VMware tools and Netstat to create visualisations for what devices are talking to each other on a network. I had a few thoughts of my own on some additional simple steps that could be taken to improve the data and visualisation still further. A few conversations on Twitter and LinkedIn, convinced me to pull them together… Read More »Extending Simple Network Mapping – TCP Port Descriptions
Network Mapping I had fun working out a simple way to extend application discovery using VMware tools, following a retweet or two (or 17) it seems like a lot of folks enjoyed reading about it too. So fresh from putting together a simple method to interrogate application data, helped by some very clever engineering from the VMware tools team and the function from William Lam, I thought I’d write up how we can reuse the… Read More »Simple Network Mapping using VMware tools and Netstat
