Worth Reading: There Is No Magic

I’m not the only one telling people not to bet the farm on Santa Claus and dancing unicorns. Pete Welcher wrote a nice blog post describing the implications of laws of physics and data gravity (I described the gory details in Designing Active-Active Data Centers and AWS Networking Deep Dive webinars).

Meanwhile, Russ White reviewed an article that (without admitting it) discovered that serverless is just software running on other people’s servers.

Enjoy!

Matt Oswalt – Speaker Bio

Photo Short Bio Matt Oswalt hails from Portland, OR, and focuses on the intersection of network infrastructure, automation, systems, and software engineering. He’s passionate about enabling engineers to evolve their careers to the next level, and sharing the bright spots that exist within the technology industry with the masses. You can often find him speaking at conferences or meetups about these topics, as well as writing about them on his blog (https://keepingitclassless.

Keeping It Classless 1970-01-01 00:00:00

One thing that’s always bugged me about the whole “You’ll be out of a job in 5,10,15 years if you don’t learn programming” is this. Who cares when you’ll be OUT OF A JOB? It’s like we’re driving a car in dense fog, trying to figure out when to perfectly apply the brakes so that we don’t go over a cliff that’s SOMEWHERE in the distance. Like - the fact that we’re even having this debate is a horrible waste of time in my opinion.

Alexa , AWS Lambda & AWS IOT MQTT and you can interact with anything

I hear a lot on IOT but don’t have a clue on underlying protocols. My interest is only to understand how it might help a business or more than that my personal interests. So continuing the server power on/off series I wanted to do it with Amazon echo voice command. Now, this is not a smart power switch where you can power-on with a command on Echo but you actually have to send a message to IDRAC, we already covered this in a previous post.

Well, the main goal isn’t to power-on a server that can be done manually as it sits beside me, the main goal is to extend this to any business / personal ideas which might get the benefit.

Summary – Develop a small interactive model to understand Alexa voice service / AWS lambda and MQTT so that we can get a feel of what can be achieved with this.

I will not go much into any tech explanations or bore you with English, I will put here two screenshots and code to git, hopefully, you should be able to give it a try.

BrandPost: How the Server Rack in your Converged Infrastructure can Speed up your Edge Computing Deployment

According to research firm MarketsandMarkets™, from 2017 through to 2022, edge computing will experience a Compound Annual Growth Rate (CAGR) of 35.4% (from $1.47 Billion US to $6.72 Billion US). Those in the business of distributing, configuring and selling IT solutions recognize that traditional IT offerings will need to be modified in order to accommodate these new edge computing environments.A number of factors influence the adaptation of edge computing in what are primarily remote locations. These include fast delivery and ease of installation, operation and management of that hardware equipment such as server racks and software. These systems also need to perform in such a way as to address latency, bandwidth cost and data location issues.To read this article in full, please click here
