Certified Kubernetes

Posted on by Nils Vogels Posted in Automation, Virtualisation

After working with Kubernetes for about 1.5 years for various customers, the time has come for Aves IT to validate the Kubernetes knowledge by certifying it’s most experienced Kubernetes expert by taking the Kubernetes CKA exam.

The exam took about 24hrs of preparation, but this resulted in a well-earned passing grade!

Aves IT is glad to help you with your questions, challenges or projects regarding Kubernetes, either on-premises, at a cloud provider, or as a cloud managed service, such as Google Kubernetes Engine, Elastic Kubernetes Service from AWS or Azure Kubernetes Service from Microsoft.

Infrastructure services.

In 2014 SURFnet was approached by 6 universities of applied science who asked SURFnet to offer a broad set public IaaS services meeting a very strict set of (security, privacy and governance) requirements. As SURFnet did not have the skillsets available which were needed to develop this service, Nils Vogels from Aves IT was brought in (end 2015) as one of two architects who investigated the requirements and proposed that a Cloud Management Portal (CMP) was to be used to create the single pane of glass access to all providers needed to enable institutions to pursue a real multi-cloud strategy.

A market analysis was undertaken to see which CMP’s would be able to meet the requirements drafted by the institutions. CloudBolt was quickly identified as one of the potential products, given the ability of CloudBolt to operate on-premises, with support for multi-tenancy and at the time 15 different cloud technologies. Nils helped draft the technical and functional requirements for the tender selecting the CMP, which was won by CloudBolt.

Nils has been given the responsibility to develop the CMP for SURFnet’s multi-tenant use and was able to have an initial version operational ready for production within three months’ time, connecting initially two VMware based resource sets and preparing for many more cloud vendor technologies, including Amazon Web Services, Microsoft Azure, OpenStack. Nils quickly became the trusted technical advisor and integrator of the CMP, ensured all issues were dealt with quickly, gave trainings on the usage of the CMP, created roadmaps with feature enhancements and oversaw the tactical relation with CloudBolt, initiating, motivating and managing all requests for enhancements and bug fixes. Nils performed all these tasks in an unsupervised way, taking control of all these processes while keeping stakeholders informed.

Nils has the ability to explain technical issues in layman’s’ terms, is fully accepted as a peer by our highly technical network and identity management engineers and write reports on a tactical/strategic level while working completely unsupervised.

Nils has been instrumental for the success of the SURFcumulus services (insert link to English website?) and we wholeheartedly recommend him to any organization looking for an architect on cloud infrastructure services or setting up a CMP.

Are you vulnerable to Flip Feng Shui? PowerCLI tells you!

Posted on by Nils Vogels Posted in Virtualisation

Trying to find out if you are vulnerable to Flip Feng Shui on your VMware platform?

PowerCLI can tell you with a few commands.

As VMware tells us in https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2097593 that TPS is enabled under certain circumstances only in recent releases.

Specifically: If Mem.ShareForceSalting is 0, or if it is set to 1 and sched.mem.pshare.salt is not set, or if Mem.ShareForceSalting is set to 2, and sched.mem.pshare.salt or vc.uuid are not unique.

So how do we check this?

First: Mem.ShareForceSalting.

Get-VMHost|Get-AdvancedSetting -Name Mem.ShareForceSalting|ft Entity,Name,Value -AutoSize

Second: sched.mem.pshare.salt.

Get-VM|Get-AdvancedSetting -Name sched.mem.pshare.salt

And lastly: vc.uuid.

Get-VM|Get-AdvancedSetting -Name vc.uuid

So, you are vulnerable to Flip Feng Shui if:

  1. Mem.ShareForceSalting is set to 0
  2. Mem.ShareForceSalting is set to 1 and sched.mem.pshare.salt is not set on every VM
  3. Mem.ShareForceSalting is set to 2, and sched.mem.pshare.salt is not absent or unique for every VM
  4. Mem.ShareForceSalting is set to 2 and vc.uuid is not absent or unique for every VM

 

Good luck finding out!

NAS2016

Posted on by Nils Vogels Posted in Storage

After a few years of steady service, my current NAS (a Synology DS411+II)  is getting old, and is not up to the task anymore of serving the VM’s I run, and while support from Synology is still very good for this productline, I do see the limitations that the hardware platform brings.

Since I am increasingly using my home NAS for lab-use, as this is sometimes required by my customers, I should step up the storage a bit, and the compute as well, when I’m at it.

My new solution will be based around an all-in-one solution for both compute and storage, and we’ll see how this goes. It’s one big experiment, really.

 

In the series of posts to follow, I will describe the following steps:

 

1. BOM and reasoning (starts below)

2. Part acquisition

3. Assembly

4. OS install

5. Performance testing

6. Additional setup

New: Aves-IT

Posted on by Nils Vogels Posted in Aves-IT

Na ongeveer 20 jaar voor diverse werkgevers in de wereldwijde IT Infrastructuur-branche te hebben gewerkt, wordt het nu toch tijd om een en ander als ondernemer anders te gaan doen. Meer de nadruk op de inhoud, minder op de vorm. Vandaar ook deze blog: Vanwege de inhoud!

Op deze blog ga je straks in ieder geval gratis en voor niets kunnen vinden:

  • Informatie over nieuwe ontwikkelingen in de IT Infrastructuur
  • Reviews van producten
  • HOWTO’s .. hoe los je dat ene probleempje nu eigenlijk op?
  • Alledaagse dingen in de IT Infrastructuur

Natuurlijk vind ik het fijn als je dit iedereen in je netwerk vertelt, maar nog fijner zou ik het vinden als je me zou overwegen voor een volgend IT Infrastructuur project. Via Aves IT is het mogelijk om volledige invulling te geven aan eenieder welk IT Infrastructuur project. Neem gerust contact met me op voor de mogelijkheden.

Mocht je hier komen omdat je op zoek bent naar een IT Infrastructuur professional, bekijk gerust even mijn LinkedIn of About.Me pagina, die ik natuurlijk graag toelicht.
