Pets, Cattle, Ants and a Lone Wolf

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

PowerShell within CloudConfig – Disk Identification Formatting and Labelling

  • simon 

In a previous post I’d worked through a few issues with formatting and labelling disks with PowerShell and part of a CloudConfig element.  I had someone get in touch with a similar issue linked to how they could use PowerShell within CloudConfig to provide Disk Identification Formatting and Labelling, for disks being added across multiple SCSI controllers. Thanks again to Dean and Chris, for providing environments for me to test against and validating the logic.… Read More »PowerShell within CloudConfig – Disk Identification Formatting and Labelling

PowerShell CloudConfig and vRealize Cloud Assembly

Adventures with PowerShell, CloudConfig and vRealize Cloud Assembly This week I had a customer with some errors trying to use the following componenets together: PowerShell, CloudConfig, and cloudbase-init within a Cloud Assembly blueprint.  To put it bluntly, the code was not running correctly.  The customer could run the code locally without any issue.  However, as soon as the same PowerShell was included within a CloudConfig element it did not work and they could not understand… Read More »PowerShell CloudConfig and vRealize Cloud Assembly

I deployed TKG 1.4 into Azure and the focus of my article is… Read More »Unable to access public load-balanced IPs on Azure Tanzu Kubernetes Grid cluster

VMware Perpetual vs SnS vs Subscription vs SaaS

VMware Perpetual vs SnS vs Subscription vs SaaS As VMware move more and more licensing to a subscription model one question I’m getting asked more frequently is “what is the difference between VMware Perpetual vs Subscription vs SaaS vs SnS?” and “what is the best way for my organisation to purchase licensing from VMware now?” Below is a quick overview of the different licensing definitions along with an overview of when an organisation might use… Read More »VMware Perpetual vs SnS vs Subscription vs SaaS

Cloud Migration Value Creation

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

VMware HCX Licensing

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?

Deploying Tanzu SQL to Tanzu Kubernetes Grid Clusters

  • simon 

Deploying Tanzu SQL to Tanzu Kubernetes Grid Clusters I’ve been reading up on the Tanzu SQL announcements I found a bit of time to have a look and some space on a Tanzu Kubernetes Grid (TKG) cluster deployed via the excellent TKG demo appliance fling. What Tanzu SQL does is enables us to operate a relational database-as-a-service function, running on any cloud.  A relation database-as-a-service function enables a developer the flexibility to install and self-manage… Read More »Deploying Tanzu SQL to Tanzu Kubernetes Grid Clusters
