London VMUG June 2017

Last month I was back in London for another VMware User Group meeting. There was a good mixture of familiar faces and first-time attendees all ready to lap up a day of learning. As usual I came away with pages of notes, so here’s a rundown of my experiences.

Nimble Storage

Peter Evans from Nimble Storage brought us the first of the sponsor sessions- “What can a storage vendor bring to your virtualisation platform?”. I’ve looked at Nimble before (including at this event) and their jewel-in-the-crown is still their Infosight analytics platform. This set the (possibly unintentional) theme for the sponsors today- plenty of analytics, machine learning, and predictive solutions.

90% of Nimble arrays are used with VMware infrastructures, and integration with SPBM and VASA features helps promote that. They’ve obviously worked hard to develop a reputation for reliability within that ecosystem. From their own figures they are reporting five-nines of uptime across all their customer estates partly helped by their cloud analytics which allow a problem at one customer to be proactively prevented at the others.

It will be interesting to see how the Nimble platform develops following the acquisition by HPE earlier this year. We were told at the VMUG that the analytics capabilities are expected to be integrated into the HPE storage platforms and we’re already seeing some product announcements.

#VMWonAWS

First announced last year, VMware on AWS is arriving this summer and Frank Denneman was here to update us on the latest developments as this approaches that GA date.

IMG_20170622_110509060With most organisations having at least a hybrid cloud strategy, and others are looking even further towards zero datacentres, Frank explained how this can cause issues with those legacy applications. He went on to talk about how cloud providers expect high availability to be implemented at an application level- VMware solved this in the datacentre with vSphere HA, but short of building a new app from the ground up it can be difficult in a regular cloud setting to emulate this ability.

We were told how VMware on AWS takes bare metal servers on the AWS global infrastructure and installs the vCenter/vSphere/vSAN/NSX stack- basically offering private cloud on a public cloud provider and consistency with the existing on-premises solutions.

This gets even more interesting as we’re promised that more and more of the native AWS services will be made accessible to the hosted VMware environment- there’s definitely a buzz in the room when this is mentioned as people start thinking about the possibilities this opens up.

Serverless

In the last session of the morning Julian Wood asked us “Can I order some servers for my serverless please?”- an interesting session with an overview of the ideas behind serverless and how they fit in with our current technologies.

Julian offered an interesting metaphor here which helps explain “serverless”- Serverless has servers in the same way that a wireless network has wires. The servers are still there, but the interaction is with the functions (FaaS) or the backend systems (BaaS) rather than the tin, hypervisor, operating system, or container.

The three main offerings of Amazon Lambda, Azure Functions, and Google Cloud Functions were discussed, along with the differences between the FaaS and BaaS services- Functions are stateless, with logic whilst BaaS offers more data longevity (for example by writing to a database) but without any logic.

My impression is that this is a new technology finding it’s niche with a few successful use cases (training service A Cloud Guru was mentioned as one) and adds another potential architecture to the catalogue of any modern application developer.

Blue Medora

After lunch there were two sponsor tracks available, SIOS were presenting in Track B and I picked Track A where Alain Geenrits and Ian Wells from sponsors Blue Medora  were talking on “Predictive Analytics for IT Operations Using VMware vRealize”.

This talk covered some of their range of vRealize Operations plugins which allow dashboards in vROps to present a wider view of the applications and infrastructure stack. These other components include storage from vendors such as Dell, databases such as MySQL and SQL Server, and then additional bits of infrastructure monitored through Nagios or SCOM.

Their system detects the relationship between these components, creating an inventory tree and helping explain to the admins and operators how the pieces of the infrastructure are interconnected.

Diving Deep

in the last session of the day Frank Denneman and Niels Hagoort gave an insight into some of the topics covered in their new book- “VMware vSphere 6.5 Host Resources Deep Dive”. “Deep Dive” is a bit of an understatement here- and you’ll have to buy the book to get the details- but there’s some really good nuggets of information that everyone can use.

For example (and check out page 224-228 of the book for the full details)- are you aware of the impact on performance that can be created by filling memory slots in a server? The performance of all the memory can be severely reduced (by as much as 25%) by the controller to prevent signals overloading the bus when using 3 DIMMs per channel. To quote their words:

“DIMM population guidelines create a challenge whether the capacity can be solved using higher capacity DIMMs or taking the throughput hit as more capacity is only obtainable by populating all DIMM sockets.”


Overall there was a good story behind the sessions at this event- from the core VMware hypervisor in the Host Deep Dive, through the surrounding ecosystem in the sponsor sessions and then out of the datacentre and “into the cloud” with talks on VMware on AWS and Serverless technologies. All of this was wrapped up by the community of attendees, speakers, and of course the VMUG Leaders who without the event wouldn’t happen.

#vBeers

As in previous years the London VMUG team upped their game for the social after the summer event and Dave Simpson once again proved he could organise a booze up in a brewery.  Thanks are also due to Nutanix for sponsoring this part of the event.

IMG_20170622_185029673_HDR

So after the close of the event most of the attendees decamped to the FourPure brewery down the road in Bermondsey for a bit of drink, food, and talking shop. As always this was a great end to the day and a real opportunity to discuss the day’s revelations alongside what we’ve all been up to back in the office. This really brings the community together and is, in my opinion, one of the major selling points of the user group experience.

Future Dates

The UK VMUG “UserCon” is back in Birmingham on 16th November 2017, and the next London date is 18 January 2018. Both events are always on the lookout for new speakers too- particularly from the community. Details and a sign-up form can be found here- tinyurl.com/VMUG-CFP.

#vBeers – trying out a new gathering

vBeer1

vBeers- “an opportunity for virtualization enthusiasts and professionals to meet and enjoy discussing all things virtualization and anything else in the world of tech”

vbeers.org

Over the past year or so I’ve bumped into a number of fellow virtualisation pro’s in the community who live in the commuter belt around London. We’ve often met up for a #vBeer or two in the capital, and I’ve floated the idea of a “vBeers in the Country”- i.e. evening meetups in a pub to talk tech but held outside of the M25. The suggestion was generally well received, so I set about putting something together. Here’s an insight into went on to organise this in case anyone finds it useful in putting on their own event.

Working out Availability

imageWhilst I could have gone with the option of “My local, two weeks on Wednesday”, I decided to try and find out when people were usually available and where they were likely to travel to for a meetup. That way we could organise something with potentially better attendance. I chose a selection of locations that I could get to by train (I thought it would be nice if I could go too 🙂 ) and put together a survey on Google Forms to find out what night the majority of respondents would be available, and where they would be interested in going to.

Picking a time and a place

We had a number of responses, and the results clearly pointed to a Thursday night in Guildford being the favoured option. Picking a particular Thursday was the next step. I was keen to avoid clashing with other tech events (local VMUGs, Cloud Camps, AWSome Days, etc.) that people might be interested in, and also avoiding January – paychecks are often stretched that month and some people join in with the “Dry January” events for charitable or health reasons which don’t necessarily play well with an evening in a pub.

Next up was picking a suitable venue. Guildford is lucky to have a number of nice public houses and many are close to the train station. Carefully navigating the calendars of the various hostelries I discovered that one of the nice riverside pubs, the Britannia, was open for food and drink and didn’t have a band or pub quiz happening on the evening in question. One twitter and email chat later and the nice staff there even reserved a table for us- and seemed happy with my “I’ve no idea how many people will turn up” position.

Getting the word out

imageThe vBeers.org website (“Where vGeeks Come To Meet”) was my first point of call following a suggestion from Jane Rimmer.  Once the page there was published I started getting the word out on the Twitters and via tech Slack groups I’m in. We also had a London VMUG event before the date and Simon Gallagher kindly plugged the event in his opening slides and it gave me the opportunity to tell people in person.

The Results

Well, after a nervous 15 minutes sat in the pub wondering if I’d be spending the evening on my own with a beer (hey, even failure has it’s benefits!) Dave and Andy, both friends and fellow vExperts from the London VMUG, were the first to arrive and the evening got going. In amongst some excellent food and drink we discussed all manner of things technical- from the new VMware releases to our latest war stories and (as Andy was bribed with points to come along) the current batch of CloudCred tasks.

What Next?

Whilst the number of attendees wasn’t massive I think we all had a good time, so I’d like to carry on the idea and see if it grows. I’ll be thinking about organising another event later in the year, possibly moving the location around- if anyone knows of a nice country pub with good food, good beer, and a garden which is close to a station let me know and we might go there in the summer. Cheers!

VMworld Europe 2016 Social, Community, and vPeople

be_Connected – The people-networking side of VMworld is vital

VMworld is not all about announcements and sessions, some of the most valuable content is found in the social and community side of the event. It brings together over ten thousand people in the IT industry and there’s always lots to talk about and plenty to learn outside of the scheduled keynotes and breakouts. The social side isn’t just about popping out for a few vBeers courtesy of a sponsor- it’s the opportunity to meet your fellow professionals, hear what their up to, what they’ve seen at the show, what problems they are facing back at the datacentre or office, and possibly what solutions they can offer for your own issues. It makes for a week of long days, but it’s definitely worth it.

The community side of VMworld started for me even before leaving for Barcelona, as I had an impromptu meetup at London Gatwick with a couple of other vExperts (great to meet you Mark and Giuliano) who were waiting for the same flight.

vRockstar2Upon touchdown at El-Prat there was just time to check-in to the hotel and change before heading off for the opening social gatherings organised by the awesome events team that is Patrick Redknap and Marco Broeken– the Cohesity “Pre-Beer Party” at the Obama English Pub and then the annual vRockstar party held at the Hard Rock Cafe. Thanks to the vRockstar sponsorsRubrik, Nutanix, Veeam, VMUG, Hytrust, EMC Elect, Zerto, and Exelerys. These events were a great opportunity to catch up with old friends and make some new ones before the conference officially started the next day.

 

WP_20161017_11_29_36_Pro_LIMonday morning saw my first opportunity to get into the Gran Fira venue, register, and get down to the VMVillage for my first taste of the Hands-On Labs. There were prizes to be won, and I finally met Noell Grier when collecting a SocialLabs T-shirt from the Cloud Credibility booth. This area was also the scene of a “Team London VMUG” photo opportunity later that morning.

 

For me, Monday evening started with a walk down the beach to the Dell EMC reception at W Barcelona, right up the tower at the Eclipse bar. This featured VMworld themed cocktails such as the “vMojito” and an “All-Flash Martini” and stunning views across the city as the sun set. Later on in the evening I got a taxi across town to the Nutanix event at Cafe Ocana. Again, there were some regular faces and I met a whole host of new people, including Stephen Foskett of TechFieldDay fame.

WP_20161020_14_01_54_Pro_LIAs I mentioned in my session write up of the Tuesday, the day kicked off with the Keynote and as I was lucky enough to have a bloggers pass (thanks again Corey Romero and the team) I managed to get a reserved seat right down at the front. Tuesday morning was also the first opportunity to get into the Solutions Exchange. Here there’s the opportunity not only to pick up some vendor SWAG but, more importantly, find out what the latest product developments in the VMware ecosystem are.

OpenTechCast podcasters Gareth and Amit interviewing (or being photobombed by) Dave Simpson

Tuesday evening was the vExpert Reception held at L’eggs with a brief appearance by Pat Gelsinger himself. Also present were the OpenTechCast team conducting interviews.

After that drew to a close a small group of us took a trip to a local pub with London VMUG’s man on the ground, Alaric. Whilst the idea of a late-night party in a beach-front club is all well and good, the opportunity to have a chat with friends without having to shout was much appreciated.

Between sessions, much of my Wednesday was spent in the Hang Space and Bloggers area in the VMvillage including some last minute preparation for by vBrownbag presentation and some time to catch up on both my own blog posts and what others had been writing.

 



WP_20161019_18_53_26_Pro_LIFinishing up Wednesday was the VMworld Party. held in the keynote hall. This year the headline band was Australian outfit “Empire of the Sun”. Again the networking continued, the hall is large enough that even with the band or DJ in full flow at the front there is space at the other end of the arena for meet-ups and conversations.

Thursday is generally a quieter day at VMworld, and it offered the chance to do one last trawl through the Solutions Exchange- looking up those products and services that people had mentioned were worth a look at. The VMvillage got quieter and quieter as the afternoon went on as people left for the airport. An ideal time to take stock of the week’s happenings and finally get a go on that circular pool table!

Circular Pool Table in the Hang Space

VMUG London January 2015

Despite having attended the annual VMware-hosted London vForums a few times this was my first VMware User Group meeting. The all-day event, held at the London Chamber of Commerce and Industry, featured a number of talks from, and discussions with, both suppliers and the VMware user community.

A Giant Mountain of Awesomeness

Following the introduction to the day, the first presentation was from PernixData and CloudHelix on using their FVP software to improve storage performance- at a very basic level, it uses flash drives and memory located on the Virtual Host layer to deliver more IOPS, allowing the architect to scale the SAN for average performance rather than the peak, and avoid the issue of stranded storage- capacity that can’t be reached because the system has “run out” of IOPS. I’ve seen PernixData before, but this was still an interesting presentation- bringing in scenes from Spaceballs, The Flash, and Flash Gordon whilst talking about a 1.6 million IOPS “Giant Mountain of Awesomeness”.

Riding the Lightning

Next up were the vFactor Lightning Talks- these were 5 short presentations delivered by community members, rather than vendors, which focussed on using VMware products (rather than buying them). I really enjoyed these talks, they were full of useful nuggets of information and it’s always nice to see where others have encountered the same issues as you (or the issues you’re about to get!) and how they’ve overcome them. Philip Coakes (@CoakesPhilip) gave some good advice on saving money and spending wisely, summed up by his comment of “Spend your company’s money as if it’s your own”. Alec Dunn (@LegoYoda) also had some important things to remember:


Swimming with Whales

After those presentations I attended a session on where VMware interacts with Docker presented by Andy Jenkins (@stonestokie) and Robbie Jerrom (@robbiej) from VMware. Everyone had heard of it, a few were using it in Dev/Test but no-one in the audience had production loads on the platform. It’s interesting to see the VMware take on Docker- it has many functionality similarities to their virtualisation platform, and is something that VMware (along with Microsoft as shown in this timely blog post from Ed Baker) are keen to show can be positioned well into a traditional virtualisation stack. I can see the benefits here, the ability to rapidly spin up potentially massive numbers of the Docker applications and the hybrid cloud hosting resilience are enough to convince me not to uninstall ESX just yet.

Is there a DR in the house?

Next on the block was a presentation from Unitrends on Datacentre failover, based around their ReliableDR product. Ian Jones highlighted the two biggest problems with datacentre failover- Failback and Documentation- and demonstrated how their product automates the process, even using existing Array/Software based replication between sites. The automatic testing (and documentation of said testing) appeals to me, but led me to wonder how easy it would be to get complacent that everything was working- do we need an “automated DR tester” tester? 🙂

Designer DataCentres

“Bringing the SDDC to life- a real world deployment”: A detailed talk from Phil Monk and Jon Kemp (both VMware PSO) and Michael Poore (Xtravirt) covering a lot of the design work in deploying a Software Defined DataCentre. This talk was much more project orientated to start with, diving into how the design process worked before looking at the conceptual, logical, and physical designs and some of the decisions behind them. An interesting mix of process and technical details.

Quick Recall

My sessions were rounded off with a presentation from Valentin Bondzio (we were told “Cloud is in the other room, and that’s a fad!”). This was by far the most technical talk of the day, and thankfully the distance between the CPU core a process is running on and the cache it’s data is sitting in is not a day-to-day concern for me. Despite the technical depth of NUMA, memory access latency, Ready states and locality, the clear presentation style meant I came away from this thinking I had definitely learnt something I hadn’t known that morning.

All in all a very good day- a wide variety of topics without a heavy sales pitch- followed by some vBeers (thanks to 10ZiG for the sponsorship). My first VMUG, but hopefully not my last.
