This and That

Over the last few month I’ve tried to expand my horizons a little bit. Since 2009 I have worked in a few different technical roles, from helping to run data centres, and setup environments for ISV engagements at IBM, to running all systems for a rapidly growing Oracle partner, whilst on the side managing 100 websites including e-commerce sites. That led into my quick stint doing tech support in the Automotive sector before moving into customer facing roles in Jan 2016. Since then I’ve always been running on a few different threads, these have been, loosely:

  • Installs/Config for ERP systems including initial system design
  • Technical training of customers in those ERP systems
  • Technical management of escalated issues (across the world)
  • Cross-team liason for high profile or highly escalated customers
  • Coordination of international team of installations consultants
  • Development of internal tooling for installs/ technical consulting
  • Management of environments for wider team

From my recent posts it’s obvious which areas on that list have received the most focus over the last few months, notably the last two, which is where all the DevOps/Code posts are centred around. The reason so much focus has been on this, and I’ll add at this point a lot of it out of work hours, is because it’s something I enjoy, something I’ve been on the edge of before, and an area of technology that I personally believe we should all be at least aware of, and able to understand the basic principles of.

DevOps was a term coined many years before it became mainstream. Mike Loukides wrote a 20 page book called “What is DevOps” back in June 2012, which is published by the world renowned O’Reilly Media. (http://shop.oreilly.com/product/0636920026822.do) That’s some time before I came across the term, although it seems I was already aware of some of the practices that now come under that umbrella. Back then I was managing E-Commerce sites, writing PHP websites against MySQL databases and moving a very static, cumbersome “tin-factory” infrastructure over to more dynamic, sustainable growth-capable platform. With a little more time and knowledge at that time I would’ve potentially moved in different directions. I am now starting to close that circle a little from the other side.

For me, career development is crucial, I am more than happy to stay with one company, or in one role, but I will always push to make more of myself, learn new things, get involved with everything possible and break down any and all barriers. I don’t do this to benefit myself, I see it as an opprtunity for me to be a benefit to those around me, both customers and colleagues.

Outside of DevOps activities over the recent months I’ve also been working on my presentation skills, with opportunities to present to colleagues and customers about various technical topics, including System Adminstration, upcoming product changes, best practices etc. This is in part due to being given more free reign with my current role, while we work out what my future roles may or may not include, and that’s if any change at all! In the background, the day to role keeps me busy, planning installs, speaking to new customers about how to deploy, speaking to existing customers about upgrades or enhancements to their systems, all the fun stuff that keeps money in the bank and roofs over heads!

The next few months may get a little busy, well hopefully they will, and all the good stuff will be posted when the chances arise.

#Code

First things first, #notadeveloper. I cannot stress this enough, I am not trained to write code, neither am I employed to do so. However, I do enjoy writing code, I find a lot of satisfaction in hitting the run button and watching something I wrote come alive. Previously I have posted many tweets and blog entries of my coding adventures over the years. My crowing achievement to date is probably the PHP/MySQL based “Asset Management” system, a glorified inventory list ability to Assign to a person, and add a list of repairs or reinstalls against the items. It automated a part of my job I disliked, and quite frankly that is exactly what I love about code. Almost all of the scripts I have written over the years have had the primary purpose of automating repetitive tasks any sysadmin can do with their eyes closed, mostly this has been silent install scripts and updaters.

Fast forward on a little from my sysadmin days, and to the brave new world (for me) of ERP. My primary day job is planning, coordinating and performing installations of ERP software into all sorts of manufacturing and distribution companies. Some are small, many are large, so the nature of, the deployments can vary slightly. That’s generally the bit I’m good at; sizing and planning the system to meet size and expectations of the end users. What we found over the last 2 years is that whilst deployments vary slightly, there is a bulk of work that is virtually the same every time round, certainly in process if not inputs, however we found that amongst the team; time, accuracy and experience could vary, significantly in some cases. Therefore a colleague of mine, with vastly more years experience in product and process went to the efforts to write an automation tool, a set of PowerShell scripts and XML files used to automate the bulk of the installation process. Roll on a few months and instantly accuracy and time were improving, which in turn was improving everyone’s experience. Gone were the days of random (user) errors and here are the days of productivity and valid errors which have much, much more context!

 

So let’s get techy on this and roll on a little further in time; following a few changes, ownership of the tool is now with me. And with a potentially different future ahead, it may only be a short term thing (it may also be long term!), so with this in mind, I sought help of people who know what they are doing, exceptionally smart developers in this case. After a couple of remote session the following has occurred:

Task 1 – Get the code secured. We can’t have something this crucial to our process hiding on a random VM with no backups.

Solution –  Git based code repository, in this case Visual Studio Team Services (VSTS)

 

Task 2 – Get the additional features into the code, but fully tested before deploying.

Solution – Branch off. Currently running with 2 branches, one for immediate fixes/quick additions, and one for next revision which will do far more than just  installing (Shhhh it’s Top Secret)

 

Task 3 – Get the code tidied up, to some form of best practices etc.

Solution – VSTS Build running PowerShell scripts with Pester and PowerShell Script Analyzer to validate all PowerShell scripts against a set of generally accepted best practice rules.

 

Task 4 – Packaging. No one wants to manually build a zip file, upload it to a SharePoint site and email out a notification for every small fix that goes in

Solution  – NuGet and Chocolatey via a VSTS Package Feed.

 

Since this became my problem, three versions of the tooling have been released, packaging only got tested this week so isn’t the primary deployment method yet, but now we have it as a capability there will be many more versions, but that just wont matter as they will always have whatever is the latest in the master branch!

 

Ok so that all explains my random tweets from evenings and weekends over the last month or so, fortunately I’ve had some incredible guidance from some very skilled and friendly development colleagues. Without those guys, I wouldn’t be anywhere with all this other than a whole load of files and folders on one machine with no backups!

 

I’d also like to give back to the community a little, so I plan to have some scripts that I write for more generic tasks uploaded to a public facing Git at https://github.com/jaward916 further to that I have below added a list of all the bookmarks I’ve been building up, especially the ones around Tasks 3 and 4, which has been the key functionality I’ve explored and implemented in the last week.

 

I stress once again, I am not a developer, please do not laugh at my code, or my very basic explanations of the tools and processes, I am learning for fun, but developing to make everyone’s lives a little easier in my world!
