Re:Invent 2018

I’m getting poked by colleagues and industry friends on the frequency of the post on my page here. I had a lot of exciting things happening with my job at Avi Networks and also a wonderful family expansion that certainly took away any second from an opportunity to write any blog posts.

There are few highlights as follow up of the biggest conference I’ve ever attended

  • The most important – the company and the product that is the center of my existence for the last year was presented on the expo floor and I had an incredible opportunity to talk to the existing and potential customers and learn a lot of great things in terms of emerging technologies and unique use-cases
  • The second important thing was contribution in the strong vExpert community by giving talk around  "API as a foundation of Datacenter operations" at VMware {code} booth organized by vBrownBags and meeting a lot of great technologies via that community. (most of them first time). The post covering my talk is published on PacketPushers community blog page.
  • Also I learned of the new unique and hype food called Eggslut.

Linux Northwest and other news


It has been three busy months since my last blog post which is difficult to accept. Before - we were almost on weekly blog post schedule.. However it doesn’t mean the professional life is boring. There are few things that require a reflection:

  • Linux Northwest Fest – probably the best community event I have ever attended. (well it was my fourth time here). It’s so crazy to get to know the crowd that drives open source projects and get more information around the projects themselves. In many cases I’m not able to easily accept that the majority of the projects will be successful, but some of the ideas are great and the common motivation of making the world freer is appealing to me. Here are few details to share:
    • The best session I had was “Automation with Ansible” – where Mark Foster (ExtraHop Networks) was able to demonstrate on how to build and test Ansible automation on your local machine. It inspired me so much that on my return I was able to automate Avi Networks deployment on my own (Avi Networks has official playbooks on Github but it’s always fun to do it on your own from the scratch)
    • Another favorite session “Harness the power of Kubernetes and Istio” by Spencer Krum (IBM) – the session was alive lab that was all done on IBM cloud. The biggest discovery was that IBM Cloud actually has its own native support of Kubernetes.  So now GCP, AWS, Azure and IBM Cloud all have Kubernetes support which makes it an official public cloud docker orchestration platform in my view
    • Actually Azure part has been confirmed by another session from Arun Chandrasekhar (Microsoft) that was called “Hybrid multi-cloud infrastructure as code using Terraform” and basically reassured that Azure is pretty serious about orchestration and infrastructure as a code.
  • The other item that I would like to touch on is Openstack summit in Vancouver and couple of the technologies that sounded new to me. The Summit was in Vancouver (which is local to me) and Avi Networks had a booth on the expo floor. I’m covering the details here on Packet Pushers blog
  • Another event that is coming soon and I'm heavily involved with VMUG Usercon - very successful annual event, and as Vancouver VMUG Leader - I'm happy to help with it
  • Lastly, I’ll do my best to be more active here on the CrispyFog page with more periodic blog posts and also Avi Networks is hiring – ping me if you’re interested – we’re looking for all kinds of smart people – the full list is here  and also more TAMs (certainly I can tell you everything about that role)

Newsletter - March 2, 2018


February wasn’t very socially active month for me – due travel and getting up to speed at work, family obligations and a bit of traveling made it pretty quiet. 

Also Vancouver with the most of the planet got cold which made me to try to limit any possible commutes including events participation.

There are only two event to cover today:
  •  I’m happy to report that as new VMware User Group leaders in Vancouver – Carlo and myself had our first VMUG meeting. All credits go to Carlo as the organizer and the presenter. Also it was very dangerous to have non-sponsored VMUG meeting, but at the end of the day it was complete success. We have a couple of ideas for the next group meetings, but please feel free to reach out to us with your own ideas. Also thank you to Fortinet for providing us with a great meeting space and taking us on a tour around the facility afterwards.
  • The only other meeting that I got invited to was Nutanix User Group. I have no idea how I got invited, but since I’ve never been to one – I registered. The meeting was in a different format with much more networking activity and almost no death-by-powerpoint side. Also Veeam as a sponsor was great in their very condensed presentation. I don’t think I’ll go back as (a) I’m not a Nutanix user and (b) the experience was good but there is no need for a repetition.

 What really shocks me when I attend local Vancouver technology meetings on
  • how legacy technologies rooted in so many datacenters that there is no way to escape unless you rip everything off and re-architect your DC from scratch
  • negative discussion about public cloud – c’mon it’s 2018 – everyone should accept it’s a question of ‘when’ not ‘if’
  • cost discussion around the first two items. How it can be really done precisely when you have risks, regulations, security concerns, unpredictable loads and surprising requirements of the applications that business decided to onboard. All cost discussion reminds me a quote from “Security Metrics” by Andrew Jaquith – “you can use the numbers to proof any statement you’d like”. Do you want to keep your DC – look numbers prove that, you want to go to the cloud – look number prove that you’re right again!

I personally tired of wasting my time on interesting but pointless problems that public cloud already figured out for you and would like to spend my time on something that has value and unique for my customer or employer. Today my article is on ChatOps – if you’ve heard of the term in 2017 – you’re ahead of me and can skip my blog post on Packet Pushers web-site.

Petr's new beginning


Mostly evidence that I'm writing it on my way from Europe

It’s been awhile since my last post, and I owe explanation where I spent my last 2.5 months. Now on my flight back from Europe I finally have time to put an update together. I hope for a short update, however can’t guarantee it.

2017 was an awesome year for me, I had an opportunity to stop my career from stalling and eventually following of the cliff to the miserable state when you go to work for one single reason, called “paycheck”. My family and myself are so lucky that currently we can afford such pause in career and find something that interests me.

The goal was to take few months easy, work 20-30 hours a week, blog, spend time with my beautiful baby and wife. It was surprising to find such a high demand in the IT security market in Vancouver. So needless to say – it was difficult to balance between lucrative contract opportunities, family and continuous learning.

When I was asked if I want to start a permanent job – it was close to impossible to explain to recruiters, HR people etc, that I would go for another full time permanent job if it’s the right company – meaning awesome and modern product, culture of doers (not a paycheck collectors), and ability to be an influencer of the product direction.

My job dating game was going for a long time, but it wasn’t a right fit, right opportunity, right location (or working remotely possibility) or right skillset. And again, because I didn’t have an urge to land a new job, I took it at as a quest for perfection. Interview questions (or mostly at this level – great conversations with my peers and industry influencers) allowed me to rethink what I want to do and formulate my ideal job.

And my patience was rewarded when first through innocent tweet around “BADaaS” t-shirt I found
an exciting company AVI Networks and their ADC (Application Delivery Controller – next generation of Load balancers). Everything about the product excites me – SDN architecture, support of multiple Public Clouds, Native Container form factor and support of container orchestration engines, integrations with VMware NSX and Openstack. Also company culture and very interesting set of customers confirm that it’s a dream place for me to be.

My role with AVI Networks becoming one of the first TAMs – where I can bring my past TAM experience and contribute in building the strongest TAM program in the industry. People I met at AVI Networks are all superstars and together we’re able to make AVI Customers the happiest customers in the industry.

I started on December 4th and drinking out of firehose. Due my previous plans and obligation we’re away for family vacation for two weeks, then it was Christmas and now I spent another 10 days in Europe dealing with a long unfinished business in Russia. (I can't call it a vacation)

Now I’m done with my travels and look forward to focus on AVI Customers, Product and TAM Program.  Please excuse me but my blogging in the next little while will be all around AVI Vantage platform, integrations and use cases. If you want to join AVI – here is an URL and email me directly if you’re interested.

Early November 2017 - Events and Technologies review


It seems that this week I had more events that one can possibly attend, and it should be few weeks to process. Someone mentioned to me recently that the technology is moving so fast and no one cares if you were Exchange 2003 guru 14 years ago, your skills need to be current in technology and it means continuous training all the time. So pour us technology guys who have to learn how to socialize.

It’s official – my application has been approved and I’m Vancouver VMUG Leader among with two other exceptional individuals – hope to get more interesting topics and speakers to be brought to VancouverVMUG next year. I already got a lot of support from Western Canada VMware team and community! Thank you Everyone!

We’ve considered doing another small event this year however the holiday season is approaching rapidly – it will make sense to do the next event in 2018. In my packet pushers blog post – I’ll cover Datrium and Rubrik technologies that were presented at Vancouver VMUG meeting this week.

TechVancouver had a couple of very inspirational talks one from Jeremy Baker (Retail Zipline) on mentorship. For me the most interesting part of Jeremy’s experience is view on Silicon Valley from a Canadian who’s born and raised in BC – very eye-opening remarks around culture, approaches, past and future of the tech. Also, Francis Dupuis, President & CEO of PayByPhone almost  sconfession presentation reminded me that most of technologists forget about everything else when the technology is cool – it’s definitely an alarm that I wish was embedded in my head. The rest of the talks also was very interesting and touched the points that don’t cross my mind daily.


Another thing this week is iTech conference Vancouver – unfortunately due my other obligations I couldn’t listen to too many sessions.

The Global Knowledge presentation on IT Pro’s in 2017 was interesting in terms on how traditional education service is trying to pivot their offering and to interest the market. Also it was news to me the Global Knowledge acquired ctc   Also I had real fun listening to Pierre Roman from Microsoft on Serverless, Microservices and Containers. The whole presentation was “We (Microsoft) are telling the developer community on how to build a new generation applications but we’ll not inform you that the approach comes from others such as Netflix and Amazon”. I decided to not get on fire by asking if the speaker considers Exchange, SQL, Sharepoint to be monolithic applications and if there are any plans to build new versions in form of microservices so Microsoft can demonstrate the power of the approach through their own applications.

Additionally I attended a couple of InfoSec meetings and talks that kept reminding us that unfortunately the factor of luck is a big component of success in any security program. However I learned few practical advices and going to publish those discoveries when I can.

URL List and coming. Back to blogging

After a few weeks of silence with an exception of a blog post at Packet Pushers on my return from FireEye conference . The reason for it is mostly there was no opportunity to sit down and get organized due multiple streams of work and life.

It always scares me that I’ll run out of topics to write but so far it didn’t happen. So I have few topics in the  pipeline but I need a bit more time to complete them.

The biggest market shaking announcement this week is VMwareintent to acquire SD-WAN vendor VeloCloud Networks  - I’m still trying to wrap my thoughts around this move – Packet Pushers discussed few very positive observations here
lso working on a security project on audit of AWS deployment - pretty new to me but exciting and energizing!

Below is the list of Interesting URL’s in last few weeks:

I’ll work on updates for my packet pusher community blog page and report here as soon as I have some published.

Securing Windows 10, Mesos on GCP and NFS Storage VMotion

This week I was mostly working on securing Windows 10 built 1703 enterprise image. It’s unbelievable how hard the customers pushed to use the product the vendor way. It really comes to hardcore tweaking and almost hacking the OS.  Collection of few hardening URLs that I come across and might help others are here:
  •           Disable Edge Icon in IE – https://goo.gl/AHexYK
  •           Disable EDGE start pages - https://goo.gl/u4Wf8f
  •           Customizing Start Menu through XML file - https://goo.gl/PSTqfV
  •           PowerShell script to remove “Standard Applications” that have are very similar to Office 365 products (Mail, Calendar, Skype, Notes etc) - https://goo.gl/4FeQjZ
  •           Very helpful set of Microsoft assets for hardening Windows 10 (v1703) - https://goo.gl/NfTdEa
  •           Previous version of the URL above with more details on differences between 1608 and 1703- https://goo.gl/wKXkJ6

The second project that was touched by me (not planned) is Google Cloud Platform (GCP). It started with preparing my refresh of Mesos/Marathon Tutorial that I did run already in 2015 just before Openstack summit in Vancouver. The tutorial that time required Vagrant to run locally, vagrant was using Oracle VM Box. In 2015 I wanted to use VMware Workstation and bought Vagrant module for VMware workstation and spent some time tweaking it to get the tutorial running. This week when started reviewing preparation steps I discovered that now AWS, GCP and others can be used. I have a significant amount of free GCP credits – so I started setting up Mesos in GCP.  

I’m almost done with the setup and will blog about it when it’s all working. But the experience so far was BREATHTAKING – I can’t stop saying “this is so cool” to myself while deploying VMs in GCP, configuring automation through Ansible and deploying Mesosphere pieces.

Switching topics - I was approached a colleague of mine, virtualization architect and former customer with the question around VMware Storage VMotion traffic flow in NFS Environment. It was interesting research project and I’m writing about my blog post on Packet Pushers

Finally few awesome reads for this week:
