I must admit that I wasn’t on the Kubernetes bandwagon from beginning. However, I’ve seen it mature rapidly over the last 4 years with an expanding ecosystem and high rate of adoption that has given me confidence that there is a future with Kubernetes and now is the time to invest in learning it. Here are the 3 things I observed over the last 12-18 months to solidify that now is the time for me to focus on becoming a Kubernetes expert:
Cloud Native Landscape Explosion
The Cloud Native Computing Foundation (CNCF) began publishing the CNCF Cloud Native Landscape back in 2016 to illustrate the projects and enterprise software that are part of the cloud native ecosystem and community. The Cloud NativeLandscape graphic originally contained three projects: Kubernetes, Prometheus, and Opentracing. Today, it includes over 48 (not including CNCF member/non-member products and projects)! Observing this type of growth signals heavy investment by organizations and individuals to improving core functionality of Kubernetes or filling gaps in the ecosystem.
When I first start working with an API, I aim for low-hanging fruit. REST APIs, by nature, should be very generic in how they’re interacted with; however, there’s usually small nuances to take into consideration. For example, I recently found out that the VMware Cloud on AWS API uses a csp-auth-token header for authentication and authorization.
While authorization and authentication to the VCF API was straightforward (SDDC Manager username and password), I struggled the first time with POSTing a new VMware license due the API requiring a specific format for productType.
In a recent post, I wrote about interacting with VCF using the API to add a new license key as a simple way to begin familiarizing myself with the API. As a huge proponent of PowerShell, I began looking for a module to talk to the API but came up empty handed. I began working on a module with vSphere admins in mind because I know the important role PowerShell plays in day-to-day operations. During a conversation with Jase McCarty, he told me about the PowerVCF project which does exactly that! The module was initially developed and is maintained by Brian O’Connell and has 50 cmdlets which covers ~70% of the API calls in VCF 3.9.0:
Today I took my first VMware certification exam in 7 years and happy to report that I successfully passed the Professional vSphere 6.7 Delta Exam 2019(2V0-21.19D) to become a VMware Certified Professional again!
A common question I
receive from customers is why they don’t see a VMware
Cloud Foundation license in the MyVMware portal. What appears instead is
licenses for each individual product that make up the VCF
edition you purchased. Which is typically:
I’ve been at VMware for 12 weeks now and continuing to work towards being a vSAN expert. One of my many challenges facing that goal is not only learning the current state of vSAN’s features and capabilities (the latest being 6.7U3) but also learning how vSAN operated in previous versions to articulate to my customers why feature X in this release is relevant to them.
VMware has released updates to vSAN 75 times since the initial release in 2014 and 12 updates in 2019 alone. So where is the best place to start for having a foundational understanding of modern vSAN functionality?
VMware Cloud Foundation 3.8 was released in July 2019 and the biggest news in this release is the addition of public RESTful APIs for common tasks that are performed for workload domains and other day 2 operations. Managing Cloud Foundation in the SDDC manager is incredibly intuitive but customers have significant investment in existing IT and business systems such as vRA or ServiceNow.
In large scale cloud foundation deployments like I work with in Global Accounts, this will be a heavily used feature because customers now have the ability to utilize existing provisioning workflows in vRA or create new workflows that allow ops teams to orchestrate even higher levels of automation. Some common operational tasks that are available in version 1 of the API are:
Commission and decommission hosts
Create and delete workload domains
Manage network pools
Cloud Foundation 3.8 also adds capability for the SDDC manager to patch and upgrade all vRealize Suite components and NSX-T. In previous versions, SDDC manager could deploy vRealize Suite but initial config, patching, and upgrades were handled manually through each individual component. The Cloud Foundation engineering teams has been rapidly deploying enhancements and this version comes just 6 weeks since the last major release.
For further details such as release notes and planning and upgrade guides for Cloud Foundation 3.8, visit VMware Docs.
Let’s be honest — if you’re a VMUG member, you get quite a few emails from VMUG and probably delete them without looking or quickly scan it and then delete it. I tend to do the latter but the one I received this morning caught my attention and quickly turned to excitement and I wanted to do my part to promote what I’m expecting to be a very beneficial event.
The SE organization at Pure has been hard at work promoting VMware VVols as it enables customers to take the next step in their virtualization journey: mobility. In an earlier post on the Pure Storage blog, Ray Mar wrote about the simplest VVols implementation in the industry. Getting up and running with VVols is effortless but there’s always those pesky minimum requirements to know about before you can begin implementing VVols.
In a previous post, I wrote about taking FlashArray snapshots with Veeam using a PowerShell script. At the time, there was a limitation that prevented Veeam from seeing protection group snapshots. The Pure Storage Plugin for Veeam version 1.1.40, was released on August 24, 2018 and support for volume snapshots created as part of a Pure Storage Protection Group are now available. Check out the KB article to download the update. Installation is a simple wizard that takes a minute or so to install.
