Lessons from great leaders, Lovell, Kranz and Liebergot #failureisnotanoption

Image
"Failure is not an option" and "Houston, we have a problem" are phrases from the movie Apollo 13 (one of my greatest movies ever, review it here). Lovell, Kranz and Liebergot have a close association to the Apollo programme, especially Apollo 13, and these great leaders are central to the story of "Failure is not an option."

It's not about the uptime - time to throw away the RAGs

Image
All network management products miss the point. Their primary focus is on monitoring uptime. This is often referred to as a RAG tool. Red, Amber, Green where Red signifies down,Amber signifies intermittent connectivity problems and Green signifies good connectivity. This serves no business purpose and cannot justify any return on investment. All the development is in looking at when the situation is acceptable but none when you are in dire straits. How is this monitoring? All it does is give you a comfortable feeling. With this approach there is no difference in the value proposition of 'ping' or a network management framework product worth a million bucks. What is required is to monitor downtime. Outages require a special view that is serialized and has the outage time. However, it is not the length of time of the outage that is important but the crucial time periods within the outage the provide the metrics. These metric times are aligned with the expanded inci

Flawed "ITIL aligned"​ Incident Management

Image
Many "ITIL aligned" service desk tools have flawed incident management. The reason is that incidents are logged with a time association and some related fields to type in some gobbledygook. The expanded incident life cycle is not enforced and as a result trending and problem management is not possible. Read the article over at LinkedIn: Flawed "ITIL aligned"​ Incident Management

Why Madge Networks, the token-ring company, went titsup

Image
There I was shooting the breeze with an old mate. The conversation turned to why Madge Networks which I wrote about here went titsup. My analysis is that Madge Networks had a solution and decided to go out and find a problem. They deferred to more incorrect strategic technology choices. The truth of the matter is that when something goes titsup, its not because of one reason only, but a myriad of them all contributing to the negative consequence. There are the immediate or visual ones, which are underpinned by intermediate ones and finally after digging right down, there are the root causes. There is never a singular root cause for anything but I'll present my opinion and encourage everyone else to chip in. All of them together are more likely the reason the company went titsup.

The best social media requires no batteries

Image
Today it is all about social media such as whatsapp, facebook, twitter or even LinkedIn. However, the best social media is Craic. No, it is not to be confused with substance abuse. Let me explain. Often when people meet around a braai , dinner table, or share either a pot of beer, bottle of wine, a cup of tea or a mug of coffee a conversation is likely to happen. This conversation is invariably about things and is referred to as Craic. And it is best reinforced with a good bottle of whisky (typically an Irish one, which would be known as a whiskey). Now talking about why some people call it whisky, and other whiskey is good Craic. Read the article over at LinkedIn: The best social media requires no batteries

The business of SD-WAN from the top down!

Image
Why would any one want to change from legacy wide area networking to software defined wide area networking (SD-WAN)? See the above infographic for more details about the technology. There needs to be a business reason for it and not a technical one. Techies, the type who don't create documentation , tend to solve problems bottom up. The technology is chosen first, then there is a retrofit of underlying processes to fit with that technology, and finally the business is coerced to wave the wand at the newly acquired widgets. This engagement model is the reason why so many projects around technology fail to deliver on business value. Simply put the problem that is being solved is not one underpinning business.

5 practices that need to be taken into account when migrating to a more modern data centre

Image
I have previously written about Prestik, Scotch tape and barbed wire data centres . These problematic locations are usually legacy environments. Data centres have become highly consolidated and require technical and operational efficiencies. Thus, legacy practices need to be corrected and this article details a few of these.

Learning from great leaders, Eddy Merckx

Image
 "I chose to race, so I chose to win." Eddy Merckx, born 17 June 1945, is a Belgian considered to be the greatest pro-cyclist ever. He sells his own line of bicycles and I have owned one since 1997. He is one of my heroes and his never-equaled domination while cycling led to his nickname, when the daughter of one French racer said, "That Belgian guy, he doesn't even leave you the crumbs. He's a real cannibal." Read the article over at LinkedIn: Learning from great leaders, Eddy Merckx

A brief history of Madge Networks including the smart cow and lamb

This is my Madge Networks memory bucket. The history over at Wikipedia here is bland and has no character. Some of the photos here are old and grainy but most of the people who worked at Madge Networks are now old farts! If you have any contributions, please inbox me .

Prestik, Scotch tape and barbed wire data centres

Image
Many times I have encountered Prestik, Scotch tape and barbed wire data centres. The reason that they are called this is because it seems these are the only tools the techies have to keep things up and running. And you know it is one, because you can visually recognize the dirt, spaghetti and graffiti around the place. The management denies any request for anything else but then still expects a quality service. The reason seems to be to satisfy budget constraints and operational service delivery in the data centre seems to be low on the list of priorities. The result is obvious, major incidents that will result in large productivity and even financial damage to the companies involved.

Checklist for Change Management - the first step to avoid IT causing a titsup

Image
The following is a checklist for change management. This checklist is not for a pilot flying a plane but for use in IT, but is named as such because pilot's were the first to use this methodology. The checklist is a form used to standardise a processes. A checklist includes a list of items to check, steps to take, or information to mine. Pilots use checklists to do a pre flight check. Checklists are useful to make sure no items are missed which may happen if a person just does what they remember. Checklists can also aid in providing documentation to aid in trouble shooting.

Advanced traffic analytics using SD-WAN

Image
  Traffic analytics is an important component of SD-WAN. It provides an ability to have visibility to the usage of a last mile, as well as additional such as information security insights. Fusion Broadband provides advanced traffic analytics (ATA) using the Illuminate platform. This is in addition to the current network performance management abilities as well as the ability to directly use wireshark to capture packets off the edge hardware. Besides last mile outages and the causation associated around the problems related to these, the next item that always comes up at a site is who or what is using the bandwidth. Fusion is easily able to answer this using its advanced traffic analytics by providing full transparency to network activity for a site owner. These capabilities exceed those provided by most firewall vendors! Read the article over at LinkedIn:  Advanced traffic analytics using SD-WAN

Boilerplate example for an IT SOP (Standard Operating Procedures)

Image
Most IT environments do not necessarily utilize SOPs (Standard Operating Procedures) but in reality it is a crucial documentation that is a prerequisite.. A SOP is a document that describes procedures. Procedures are ongoing processes which are open ended as opposed to projects which have a definite starting and ending time. Commissioning a system is a project with tasks that end at a point where the system is "standing", nearly like a building is standing when it has been erected. SOPs are those procedures that are executed after the system "stands". Hence, standing operating procedures.
