Physical data loss in a virtual world, who ya gonna call ?

Every IT admin has disaster stories of data loss. Most people have seen the picture of the IBM array that fell through the upper floor of the DC.

Unfortunately not every admin has good backups though. Admittedly, it is not something admins like to think about too much. Speaking to KrollOntrack revealed an interesting story about virtual data loss.

Whilst everything about virtualisation gets quicker, automated and more densely packed the risk of data loss increases.  It only takes one bad action, intentional or otherwise and its a case of “Dude, where’s my VM farm gone.”

Speaking to Ernesto @ Ontrack it is a common occurrence. Reasons for data loss include many different scenarios… human error, power loss, malicious deletions, floods and natural disaster, physical array failure… The list goes on.

“We are not here to sell you anything” was a true reflection on the reactive service that you only need when something bad has already happened.

Hopefully I will be writing an interesting new  in-depth article on this for those that are interested in the how, the where and they why but for now, if you want to hear some interesting stories I recommend you drop by their booth @VMworld.

And as a parting thought, to put it into context, shipping an entire array to the clean room for recovery is quite a normal occurrence! Feel you inner nerd.

 

New VMware virtual toys… Desktops, HCX and other thoughts

The big message from this VMworld is as to be expected, hyper mobility at both the client end and the server/cloud end.

Any solution, any device anywhere is already very well known for end user computing but VMware have put their money where their mouth is and added support for Chrome devices for Workspace one. It now means that all the major players are supported.

This whole any device scenario gels with something I had noticed in general as I attend various events… more people than ever are utilising tablets and similar devices rather than classic laptops. Some misguided people even had the Ipad Pro *JK

Moving to the cloud side, it delivers HCX technology. The HCX technology allows the migration of workloads between on-premises, cloud or other other solution. We have all been there, where we have to do a migration and the downtime whilst a server is migrated. HCX solves that solution. It provides a way to do away with that downtime. It isn’t available yet, but it’s coming and it will make life very intesting. It is part of VMware’s play to be the glue that connects all the clouds together.

This change (which I assume includes parts of NSX) has vast ramifications. Think about it this way.. If you have one network that expands to cover all your environments where the VM sits is no longer important. It could be on-site, on cloud. No one cares (except the beancounters!)

This also has huge ramifications for DR.  Normally DR, even virtual DR means that failing over requires some manual or automated configuration (ie IP addreses, host names, firewalls, applications etc.)

Reconfiguring that virtual machine, under pressure of a real DR could be a real pain. That pain is about to go away. With the new VMware stack it means that in a DR scenario bringing up the DR instance becomes a much simpler scenario. No having to re-ip or rename virtual machines and then hope for the best.

Interesting times indeed.

VMware on AWS… What’s your scenario

Last year we got teased about VMWare on AWS but now it is time to show about it. We all know the VMWare / AWS is the future. How to get on to it? Depends on your scenario:

  1. Maintain and expand
  2. Consolidate and migratie
  3. Expand capacity

vSphere can help with all those scenarios. Build your vSphere stack in less than 2.5 hours !

AWS is a full SDDC stack  (vSphere, vSAN, NSX) deployed on bare metal and vCenter as control plane. It  is that simple.

Hybrid link mode for single pane of glass, tick.  Everything just works as expected as it is just vSphere under the hood. As I alluded to recently in an interview about AWS and vSPhere, it is VMware cloud. Support, VMware, Billing. VMware. It is VMware (just to push the point home.)

AWS do get a look in too. AWS serfices such as RDS, S3, IAM can also be consumed by VMware on AWS cloud customers.

vSphere on AWS Nodes consist of:

  • Compute 72vcpups
  • 512 GB ram
  •  14 TB NVME storage, 10 usable.

Other new interesting features include elastic scale. There are also several consumption models including consumption based, ad hoc (credit cards, PO’s etc and lastly, and perhaps most importantly, Hybrid Loyalty program.

Oh and lastly, VMware take care of your patching. More on this later as I am sure a lot of people are interested in that (for better or for worse).

 

 

So it came to be, VMworld Europe 2017

After a bit of travel I have arrived. I am expecting many new and interesting things this year, not least AWS and VMware, all the items they teased us with last year should all be unleashed upon us.

For those returning from last year, the whole VMworld layout is completely different so it may take some getting used to! The new badges are useful though because the password for the wifi is on the back of the rather large attendee pass (as well as a map of all the locations!)

Don’t make the same mistake I made 😉

Need to find an AWS person to talk to and get some VMware on AWS exposure…

Preparing for VMworld 2017

VMware have been gracious enough (or brave enough, depending on your point of view) to invite me back for VMworld 2017. Flights and hotel is all booked but for those VMworld virgins I thought I should post back to my post of items to remember for the Next VMworld.

There are lots of tips in there and it will save you time and hassle if you haven’t done it before!

Really looking forward to it and I am expecting some really good announcements to come out of this years VMworld. It will be especially interesting to see what, if anything, has changed re: VMware IOT offering.

Anyhow, Public service annoucement over!

Privacy As A Service, what might it look like

Privacy has become a valuable asset in today’s world and therefore the technology to protect it has become a very marketable product. When online privacy is mentioned most people automatically think about their Internet web browsing history and social media footprint.

“Every day young adults will call me up and tell me that they can’t get a job due to an ill advised tweet or Facebook issue…Education is key.” – Tony McChrystal, reputation.com

Unfortunately, the more high profile people are, the more people will make use of their online footprint and rarely for good.

The meaning of privacy

According to Dave King, CEO of Digitalis reputation management, all major recent high profile hacks including the Sony hack originated from strategically valuable individuals compromised by highly targeted attacks. The TalkTalk hack is the sole exception to this.

Your browsing history and online profile is only a tiny fraction of a much larger data picture. Publicly available data include the land registry and voter registration databases that a large proportion of us are recorded on.

A quick search of 192.com will tell anyone who has your name and postcode with full name, address, age, neighbours and property price.

Many online retailers use this publicly available data combined with users browsing history to make decisions about what items will influence their purchasing decision.

Each visit is carefully customised to provide a “frictionless” experience in data engineering terms. The more a specific site is visited the more information about the users habits are gathered.

If someone have a Google, Yahoo or Facebook account they are not the consumer, they are the product. Put simply, the more information these companies have on users the more accurately they can target them with highly tuned adverts.

Neterix, a company that specialises in privacy compliance for business commented:

“People are more aware of the value of their personal information, yet so many are willing to trade some of it for “free” services. People have to choose if that service is worth the potential privacy cost.” – Les Pritchard, Neterix.

As an individual people have limited recourse to have such information removed. Privately held databases are allowed to hold information on people as long as they abide by the data protection act (If it applies.) As long as the information is correct and used in a fair manner companies are not compelled to remove it.

The breadth of data detailed above barely scratch the surface. Several private information brokers provide even more detailed information on individuals for a fee. These companies include Experian, Equifax and many large financial organisations.

There are such a huge number of data vendors that trying to take back control of data using opt outs could become a full time undertaking and you can be sure these providers will not want anyone to have an easy ride removing the information as doing so is not in their interest.

Although there are not yet many products on the market for  “Privacy As A Service” they are starting to appear although predominantly targeted to the American market at present

Speaking to several experts on the subject of what privacy as a service looks like there was a common theme about what privacy as to what it might look like.

When asked what such an all-encompassing privacy service might look like King puts it this way:

“A service that manages my services long term and looks to manage my data as a whole, who may have access to it and for what purpose. It should have an educational component as well.  Ideally it would automatically search and monitor for my potential privacy issues.”

Common consensus across all the experts interviewed is that privacy as a service would take the form of a web based portal that will integrate privacy controls alongside a more conventional ad and tracking blocking technology.

Such a service would essentially provide a one-stop shop for management of your online profile and implement privacy controls in a consistent and controlled way. This would allow everyone to avoid online tracking

Some companies will attempt to remove  information from as many online services as possible, for a fee. All these services come with a caveat that they cannot control all the information, all the time. No matter what someone wishes for some records will inevitably stay on the web, especially where required by law.

Interestingly on a similar vein the recent “right to be forgotten” has had a mixed effect since its inception. Google’s own data would suggest that as of July 2015 Google had received requests to remove 1.25 million URLs based on 353,484 requests.

Google has also revealed that the ten most common removal requests represent a mere nine percent of all requests received. Somewhat unsurprisingly the top website for removal requests is Facebook. The second most popular site however is a profile search engine utility. This fact underscores how important it is to pause for thought before putting information on publicly available websites.

“You have to try and understand how your data is going to be used in the future and what it will be used for in the future and be aware of the changes in technology may render it useful in unforeseen ways” – Jim Killock, Open Rights Group

Peoples data is valuable and unfortunately many sites are built around the premise of collecting and mining user submitted data so those using the service essentially become the product and users data is sold on to third parties, none of whom the end user gets to know about.

Until such services are widely available anyone wanting to protect their data should look at what information they give to whom and for what reason. When using online social media familiarise yourself with the privacy tools the vendor provides. At the end of the day it is up to the individual to think before giving away valuable data.

Catch you later!

 

VMware vCenter HA – How to

One of the major shortcomings of vCenter has been lack of HA for vCenter. HA has been around for a long time but it never supported dual CPU so therefore no use for vCenter.

With the latest version of vCenter VMware have addressed this issue and created a purpose built vCenter HA configuration with a separate heartbeat network. What’s even better is that it is really simple to implement, manage and test.

You can read the full how-to of implements vCenter HA here.

Laters!

Dell XPS – The inside story

Hi Everyone,

Just thought I would create a quick blog post to mention my behind the scenes interview with Barton George and Jarred Dominguez of Linux of the Dell Linux on Laptops  fame.

The Dell Linux on laptops interview has been published in the latest edition of Linux Format. It covers how the Linux on Dell offering came to be and the the ups and downs the team experienced.

The interview covers the project skunk work startup, near brush with death and its eventual rise to fame as well as what to expect in future.

Many thanks to Barton, Jared and the Dell PR staff!
