Editor's Corner

This week's newsletter continues from last week and includes reflections by some of my contacts in the global IT community about the Intel Spectre/Meltdown fiasco and how IT pros can deal with it. Plus we have all sorts of other stuff to keep you informed and entertained.

Speaking of melting down, what would you do if our global financial system melted down? How could you prepare for such an eventuality? Here's some advice from Dilbert:


Hmm, maybe Alice has it right.

And now on to the main topic of this week's newsletter…

Reflections on Intel's Meltdown

I reached out to a number of my contacts in the global IT community asking them if they would share their thoughts, suggestions, or warnings concerning the Intel Spectre/Meltdown vulnerabilities. Several of them responded so I'm including their reflections here as they may help some of our newsletter readers devise strategies for dealing with these vulnerabilities. If you have any additional thoughts or suggestions you'd like to offer on this subject, you can email me at [email protected]

Thoughts from an Azure consultant

These first reflections are from Marnix Wolf, Senior Consultant and Azure evangelist at Didacticum Group in the Netherlands. Marnix is a senior consultant, with a strong focus on Azure (IaaS/PaaS), Microsoft Operations Management Suite (OMS) and the System Center stack, mainly Operations Manager (SCOM) and Configuration Manager (SCCM/ConfigMgr). Marnix also writes a blog about OMS, Azure and SCOM which you can read here:


"My two cents on this topic are that whether or not to roll out the patches for Meltdown, depend on a per case basis. Servers hosting VDI or database related workloads are the ones who take the biggest performance hits, far over 30%. This could result in a direct degraded performance of the offered service, hitting business in pretty bad way. Many times, for workloads like that servers aren't easily added in order to make up for the performance loss. But this doesn't mean in cases like that the patches shouldn't rolled out. Because many times, security and privacy in environments like that are paramount. As a result, companies are rolling out the patches but in batches, monitoring the total impact because it's quite hard to make a sound prediction.

To make it more complex, the patches weren't properly tested, because the news leaked out too fast. As a result, the available patches were rolled out while lacking proper testing and their results. So companies like Microsoft found themselves in a split. Either to make the patches available and make them look bad because the patches themselves introduced new issues and challenges, or not to roll them out and make them look bad as well. So now the patches are available but do have warnings because there are potential risks attached to them. As a workaround - for the Microsoft patches - you can prevent the installation. But when you do that, future patches won't install either. Meaning, somewhere in time, the patches for Meltdown HAVE to be installed, because the alternative is even worse, making your systems vulnerable to other exploits as well for which are patches available but not installed...

Cloud providers are obliged to installed the patches, no matter what. Because most of them have their business model based on the principle of maximum usage. Meaning their server hardware is used to the max, 24/7. This can only be done when you rent out the same server hardware to multiple customers. As such they are required to roll out the patches, even though it affects directly the performance of those very same servers. As a downside, those very same servers will allow for less workloads (because of the performance degradation), which is a direct hit on their business model. And this is only the patching of Meltdown, because Spectre is too hard to patch, if it can be patched at all. Finally the cloud providers have to replace their servers much earlier then expected, because in order to address Meltdown and Spectre properly, a new CPU design is required.

Finally every business running servers of their own, whether physical or virtual have to roll out the patches. In some cases, like Microsoft Azure, recommend NOT to roll out the patches on certain types of Azure VMs because that would run the performance too much. These are the lowest type of Azure VMs, running slow CPU's and a low amount of memory. 

As you can see, there is not a simple answer. It not only depends per company, but also per workload, per agreed SLA and required security/privacy, whether by law, regulations of signed contracts with the customers, whether internal or external."

Other reflections on Meltdown/Spectre

Several other colleagues I contacted responded briefly with their thoughts as follows:

Hi Mitch, luckily all my biggest customers are awaiting the implementation of the fix. At the current stage I think monitoring is more important than fixing the problem hastily and risking new and unknown challenges. Such mayor changes deep down in the core will need extensive testing, and focusing on monitoring systems and outgoing network traffic to discover patterns of exploit are critical. --Olav Tvedt, Microsoft MVP (Cloud and Datacenter Management) and Principal at Lumagate AS in Bergen, Norway. 

Olav's also has blog called "The Magic Between Data and the Users" that you can erad here:


Well first of all, with this kind of approach from Intel, it's quite hard to trust them on this matter but at the same time we have no choice but to wait. I feel like we're that their mercy as they are the verdor/chip providers which powers our servers. We just hope that the next patch for Meltdown/Spectre that Intel provides would be the permanent fix to prevent unnecessary extra work for our platform & server teams. --Jay-R Barrios, Microsoft MVP (Cloud and Datacenter Management) and Senior Systems Consultant for the NCS Group in Singapore. 

Jay-R also has a blog called "JDeployment" which can be found here:


You are right about it being a fiasco, these last couple of weeks have been hectic to say the least. But luckily for me, we at the university have teams to deal with this type of scenario. I am not directly affected but I do deal with the teams that are affected and see the demand that is put on them. Having to patch every system on the network. --Jeremy Hodgson, Data Center Coordinator for the University of Manitoba and Winnipeg Technical College in Winnipeg, Canada.

Factoid of the Week

Last week's factoid was this:

A company in France has developed an airbag device that seniors can wear around their hips to prevent them from injuring or breaking their hip if they should suffer a fall. Older IT pros should definitely buy one of these when it becomes available, right? Seriously though, what technologies help prevent you from injuring yourself in your daily work or life activities?

This brought a couple of responses from our readers. First here is one response that I totally agree with:

Question: What technologies help prevent you from injuring yourself in your daily work or life activities?

Answer: Coffee

-- Doug, Systems Administrator for a Department of Corrections in the USA

Next here is a fascinating tidbit about a serious use for personal airbags:

Mitch, my sister is a competitive horseback rider who has been using an airbag vest for years now (and swears by them, despite some of the comments in the article):
I'm not surprised to see this technology applied elsewhere, personal protection for seniors certainly sounds like a good idea to me.
P.S. I am a long-time reader WServerNews, thank you for producing one of my favorite weekly newsletters.

--Tim from San Diego

Now let's move on to this week's factoid:

Fact: A new study reportedly exposes the sugar industry's decades-old effort to stifle research linking the eating of lots of sugar to heart disease.


Question: How much sugar do you consume each day? And do you use any sugar substitutes? If so, which ones and why?
