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.

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.

London VMUG January 2017

Last week saw the first London VMware User Group of the year, another great meetup with many of the usual faces along with some new ones. This was another informative event at the TechUK site just off Fleet Street, and was again very community orientated. If you want to go and find out how people are using VMware products (and others in the surrounding ecosystem) then I’d thoroughly recommend these events- there’s just the right balance between real technical accounts direct from the coalface and marketing of new and interesting products Continue reading

2016, a year of industry friendliness

You may have seen various posts in blogs and social media over the past few days about VMware staff accounts being blocked from joining the Nutanix community website, and the VMware User Group- VMUG- blocking Nutanix staff from leadership committees. I’m not party to the detail or the reasons behind these moves, but I’m surprised at the developments with the backdrop of 2016’s collaborative direction. As an industry we managed so well being friendly in 2016 despite the divisive world landscape with things like the US Election and Brexit, what happened over the Christmas break to mess this up? Here’s a few things I picked up on in the past year which paint a picture of much more inter-vendor friendliness, hopefully the issues in this particular case will be ironed out quickly and we can revert to business as usual.

VMware (and Amazon Web Services)

VMware’s 2016 announcement that you will soon be able to run their hypervisor on AWS may have rubbed a few of the vCloud Air vendors the wrong way by picking a collaboration with their biggest competitor. However, look at the positives- VMware are creating a standard platform whereby customers can take the workloads they run on AWS and port them to one of the smaller vendors if it makes sense to do so. This could even be automated- if AWS is more expensive in a particular month than another provider, some or all of the customers workloads can be migrated across.

The Dell purchase of EMC (and therefore VMware) had a few people worried that the hardware side of the VMware ecosystem would be destroyed- DellEMC would push their own traditional , storage, compute tin and hyperconverged platforms at the expense of the competition. Both Michael Dell and Pat Gelsinger have been consistent in their message that this won’t happen.

There’s also other good signs from VMware with their VM encryption package in vSphere. Rather than providing a VMware Key Management System, or insisting on an application provided elsewhere under the Dell Technologies umbrella- the requirement is just for a KMIP compliant service.

Microsoft Loves Everything

Microsoft also surprised a few people with their friendly approach to former competition recently- even to the extent that Steve Jobs and Amazon’s Alexa featured prominently in a Keynote at a recent Microsoft event I attended.

We’ve seen for some time that Microsoft Loves Linux  and Open Source. And these days they get on pretty well with Apple and Google these days, focusing on their flagship applications on Android, iOS, and MacOS and sometimes adding features there ahead of their own OS.

#VMUGgate

So, I hope this current grumbling between Nutanix and VMware either turns out to be nothing or everyone turns around and agrees to just get on. The London VMUG team sound like they agree:

Events Calendar 2016-2017

It’s that time of year again, when we change the calendar on the wall, look back at what happened in the previous 12 months, and look forward to what might be coming in the next 12. Here’s some of the in-person events I enjoyed in the last year and some rough plans for 2017. The right sort of in-person events are a great opportunity to get out of the office, learn about new and existing technologies, and meet your peers. I find such events invaluable in my day job to avert the risk of living in a tech-bubble, doing things how they’ve always been done, and only using the kit that my preferred supplier’s sales department recommends.

 

2016

Aside from my playing far too much Minecraft, I went to lots of exciting places in 2016, for example……

VMworld Europe 2016
I was here as an official Blogger seeing (amongst other things) the release of vSphere 6.5. I also managed to squeeze in my first vBrownbag presentation – I think adding “International Conference Speaker” to my CV might be a little excessive, but it was a great opportunity.

VMUG
This was the first year that I made it to the full set of London VMUG meetings, culminating in the annual UK UserCon in Birmingham in November. At the UserCon I chaired a roundtable discussion about IT in Higher Education.

Insight Technology Show – I’ve been to this annual springtime event in London for many years now as it’s a great opportunity to see lots of different vendors in one day all under one roof. This years’ was a bit of a more subdued affair (I’m guessing because of the economic climate), but a useful day out none the less.

-Microsoft tech day in February titled- “What’s new in Windows Server 2016: Building a more flexible infrastructure”. A great Hands-on event

Microsoft Future Decoded returned to the Excel centre in November, I attended the Technical Day. Future Decoded has an interesting mix of content- in a breakout session you can watch SCCM and SQL Server being deployed with PowerShell, and then walk into the Keynote and hear about how scientists are able to detect sound from silent video footage (Watch this TED presentation)

 

2017

The following year has some good events already in the calendar, more of the same and maybe even something new. I’m hoping to make as many as possible:

VMworld 2017The European leg has been moved from it’s usual slot in October to 11-14 September and is again in Barcelona.

London VMUG – Dates are 19th January, 6th April, 22nd June and I expect a UK VMUG Usercon to follow in November.

I’m also trying to put together a local vBeers event – out in the “Countryside” rather than in London. Details to follow, event will hopefully be in February.

Microsoft pulled their big European tech conference back in 2014 and there doesn’t look like any hopes of a resurrection (especially as even more conferences are being folded into Ignite), but there’s usually some good content at the smaller scale local events.

And who knows what else the year will bring?
