  • AWS Console: VPC+SN+SG+EC2+RT

    In this post, I’m going to detail my journey building out this infrastructure. Here’s the goal: The goal is to practice a few things besides the deployment of these resources: INTRO: There’s a lot of directions that this project can grow, but the scope for this particular project is limited in scope: the ability for…

  • EBS and EC2

    I’m exploring with EBS volumes – that is, Elastic Block Storage – and there are some interesting characteristics that I’ve discovered. They are viewed at a type of “network usb stick” in that the EBS volume can be “unplugged’ from one instance and plugged in to another one; they are versatile in that way. That…

  • Terraform: Data Source: Debian > Amazon Linux 2

    In my previous iteration of using Terraform to configure AWS resources to build out the infrastructure needed (VPC, AZ, subnet, security group, Internet Gateway, Subnet Association) to host a running EC2 server, I used a Data Source that spun up a Debian instance. That worked great but tbh I have been spending most of my…

  • Creating AWS Launch Template for EC2

    I’ve been creating EC2 instances on a one-off basis, which is great practice, but as I am wanting to learn how to use IaC methodologies, I wanted to explore creating a launch template. First, I selected Launch Template from within the EC2 dashboard. I gave the template a name, selected the Amazon Linux x86 AMI…

  • First Foray into CloudFormation

    I’m interested in learning Infrastructure as Code, and since I’ve been diving deep into the AWS waters, decided to cozy up to CloudFormation. Here’s what I did to launch an AWS EC2 instance using that tool: First, I created a stack and uploaded a custom .yml file There were a few attribute options, but I…

  • Attaching EBS Volume to EC2, Creating Redundancy

    I’ve been exploring the AWS cloud ecosystem – first, creating a VPC with a single public subnet, a security group that corresponds to that (port 22 and 80 open for SSH and HTTP), attaching an Internet Gateway to the VPC, attaching a route table to the subnet. I spun up an Ubuntu server within the…

  • VPC+Web Server + DB (pt 2)

    In my previous post, I followed a tutorial which set up a VPC, along with four subnets (two of which won’t be used), each situtated in their own Availability Zone for increased security. The DB in one, a private subnet, with a security group that is locked down -only the EC2 server, in the same…

  • VPC + DB in Private Subnet > Public-Facing Server (pt 1)

    I’ve been deep-diving networking, Linux, and studies for the CSA, so time to start pulling everything together! I decided to follow a tutorial for creating a VPC with a private subnet holding a RDB and a public-facing EC2 instance/server in a second subnet. This is a pretty common use case, so a great place to…

  • Hyper-V Virtual Machine Practice

    I’ve been spinning up VMs using VirtualBox (by Oracle), including Centos 7, Kali Linux, Ubuntu- and for this exercise I am jumping into the Windows world to spin up a VM there. Above, you can see that I used the VM Wizard to provide the attributes that I want, setting memory size, networking (external), hard…

  • Connecting VM Centos 7 to internet

    I have a Centos 7 virtual machine on my virtualbox hypervisor, which has been great for practicing vim and such. However, when trying to get onto the internet, I wasn’t successful- and poking around the configuration settings of the software platform didn’t seem to work (without doing a deep dive, anyways). I followed this video,…
