Writing effective scripts using VMware PowerCLI

30/12/2017

20171224-00Lately I have been busy writing some Windows PowerShell scripts for a vSphere environment. I noticed that there are some similarities between learning a spoken language and a programming language. In both cases you start by learning the grammar and vocabulary and develop your skills by a lot of practicing. But for both skills, when you have not used them for a while, the skills will fade.
While writing and testing my scripts, I realized that a good preparation and a structured way of working will help you becoming more productive and making fewer mistakes.
This post is not a full blown Windows PowerShell course, but contains some insights I would like to share with you. If this is all new, I recommend following a PowerShell Getting Started training. Pluralsight offers over 11 Windows PowerShell courses from beginner to expert level. So if you are relatively new to Windows PowerShell and the VMware PowerCLI, please read on.

Do you need to know Network Virtualization ?

06/03/2017

Why NV?

20170304-01I recently took the VMware Certified Professional 6 Network Virtualization Exam. Preparation for a technical exam like one of the available VCP exams takes a lot of your free time, so why choose this one?
In recent years, I increasingly encountered the product NSX Manager, usually in VDI deployments with endpoint protection products like McAfee Move, Trend Micro Deep Security, to name a few. And while working on the upgrade of a VMware View environment, also comes the question, how to handle the endpoint protection part; How do we upgrade these components?
In the concept of the SDDC, besides the well known Compute and Memory providers, I consider Storage virtualization (like vSAN) and Network virtualization (NSX) as fundamental building blocks that should be part of your “basic” VMware knowledge.
I also noticed that VMware is doing a lot of promotion for the subject of micro-segmentation, and for a good reason.
So, I decided the time has come, to extend my knowledge. So where do you start? If you are on a VCP-DCV level, but cannot tell the difference between layer 2 and layer 3, I recommend start reading a book like “Networking for VMware Administrators” by Chris Wahl and Steve Pantol.
At that time, I was in between jobs with no budget, to attend regular VMware training courses like the “VMware NSX – Install, Configure and Manage” course.

All Hands on Deck / VMware

19/02/2017

201701-01Although VMware is best known for its core virtualization product vSphere, it may not come as a surprise that since their first product releases, a lot has changed. Over the years, on top of this solid foundation, VMware built a “Software Defined Everything” stack (SDDC), a Cloud stack with all the Automation and Orchestration tools, Monitoring tools, an End User Compute environment etc. This has led to a very large number of VMware products.
As you are as curious as I am, product
data sheets and documentation maybe helpful, but the best way in my humble opinion is to download, install and try the bytes yourself.
In addition to options already there, VMware launched a new one; Product Walkthroughs. So time for an overview how to get familiar with these fine products.
