I was recently asked if Azure PaaS (Web Apps) & Azure Load Balancers supported Web Sockets, and I said yes, because well I read that it did. But I never tried it so I figured I’ll follow the Chat App tutorial from socket.io to try it for myself. Easy enough, I created the local app, added it to a git repo then deployed it to Azure Web Apps and everything worked as expected (How to use git to deploy node to Azure? Read: Continuous deployment using GIT in Azure App Service).
TL;DR: Clone & follow the steps from my GitHub repo WCFDemoApp to get started.
Recently I was able to work with a local company that had a fairly common 2-tier environment consisting of a web front end in ASP.NET and a middle tier (API) using WCF connected to a SQL database all hosted in their co-location environment on their own servers. They wanted to move this workload to the cloud and so I took this opportunity to build a walkthough on how to do exactly that.
I had an interesting call with a partner this week where the client of the partner did not want the servers (virtual machines aka VMs) deployed to the public cloud (in this case Azure) because of potential downtime. Their fundamental concern was due to planned maintenance where the host systems are patched & rebooted as needed which can lead to downtime. This is one of those good and bad things. The good being the host systems are patched and up to date (good for security & overall system health) but yes bad because it means that the system could be down for a short period of time, but only if you only run single instances!
As a Technical Evangelist I have a lot of opportunities to speak to small and large groups of people. This could be online (webinars & blogging etc.) or in person with customers as well as at events and conferences. What I’m getting at is I get to do a fair bit of presenting. I am by no means a “professional presenter” keynoting large conferences (quite the opposite), but I have picked up a few tips (sometimes the hard way) that I’d like to share. I hope this will grow as a series of posts on the subject.
The first is about timing which in regards to presenting I’ll break into two key areas: cadence & time management.
There are countless resources just a quick search a way that will list all the things you should study in preparation for a particular exam. Likely you will find Microsoft Virtual Academy courses, TechNet/MSDN articles, blog posts, books, practice exams and much more. Let me be clear, those are all super useful.
However, I will share how I passed the exams, which is not to say how you can or will, but if you are like me (just a bit?), maybe this will be helpful.
This seemingly innocent, possibly factual statement of “not in my job description” gets my blood boiling. Without going into the details of who’s and when’s let’s just say I’ve been hearing this more and more from people as they complain about their jobs. Anyone who has ever worked with me has certainly heard me get on my soapbox and give the same speech:
“I will never ask you to do something I haven’t done a dozen times myself”
I came across an interesting bug today that could show up in environments where source content is minified. The core of the issue was a regular expression (aka regex) that would work on content that had whitespace and newlines, but not on the same content which had been minified (whitespace & newlines removed, names shortened etc.)
