I'll start by saying I have a very general understanding of DNS. I know it's often dubbed the “internet phone book” and that it translates IP addresses into URLs. I know some of the various DNS record types off the top of my head — A, AAAA, CNAME, MX, TXT — along with how each of them are used, but mostly at a high level.
As a baseline...
I just finished the Virtual Private Cloud (VPC) section of the AWS Certified Solutions Architect course and I wanted to write it out in order to gain some clarity around it.
For some reason, this has been the hardest topic of the course so far. There were certain things that were easier than I thought they'd be (subnetting), while others were much more difficult (NAT Instance vs NAT Gateway).
I've been thinking about obtaining a more professional domain name for some time now, but didn't actually pull the trigger on it until last week. I ended up purchasing two domains, which may seem silly, but there is some logic behind it.
I have to preface this by saying that I am not a developer. I can read snippets of code and muddle my way through certain things, but coding is not my strong suit.
Having said that, I need to break down API Gateway as much as I can in order to better understand it.
Serverless architecture is the current topic I'm learning in the AWS Certified Solutions Architect: Associate course from Linux Academy. It's a bit of a challenge for me because I don't have any real experience with it, but I understand the concepts at a 30,000 ft level.
I'll start with what I know and then get into some theory I've compiled.
I spent some time a few nights ago completely overhauling my resume. This is really for a few reasons...
I had originally intended to write this post about flowchart topology, but the more I wrote, the more I found myself writing about knowledge management, so I'm just going to run with it.
As I mentioned in my first post, I'm working my way through the AWS Certified Solutions Architect certification training course. I finished the EC2 Fundamentals course last night and just wanted to write some of my thoughts on it as I move onto the Intermediate coursework.
Since I'm currently going through the AWS Certified Solutions Architect course offered by Linux Academy, I'm going to need to write things out so that they make a bit more sense to me. Today, it's going to be the differences between Instance Stores and Elastic Block Stores.
First and foremost, I'm Dave. Rather than a formal introduction, click here instead to learn about me.
I'm not entirely sure what I plan on writing in this, or if I even plan on keeping it. It's more of a spur of the moment thing to do, especially since I've never really had any interest in creating or maintaining a blog.
In any case, I'll get right into it...
