Still trying to really grasp the concept of VPCs and route table. This diagram, which contains actual clouds really brought everything together for me. Also, it was pretty relaxing drawing everything out and then coloring everything in. I think I’m going to draw out a few more of these diagrams.

How to learn about VPCs…

I keep reading that VPCs (Virtual private Cloud) is such a huge chunk of the AWS Solutions Architect Exam. I’ve always with been the most shaky on this particular AWS service. I feel like I’ve just figured out how to properly set one up, so I really need to focus on this area. I have to do a presentation on AWS to my class next week, so this is a great opportunity for to really go over everything with in detail.

I made these slides to help me get the difference between Security Groups and Network ACLs. I set them up as if they were sworn enemies and there can only be one. I’m pretty sure Network ACLs would win in a fight. They just seem like a safe bet. I’m not sure my class will appreciate the super hero homage, but listen, we all have our learning aids.
