Hosting a Static React Application on Amazon S3
Amazon S3 (Simple Storage Service) is an AWS service for storing objects. Since objects are files, S3 can be viewed as a filesystem accessible over HTTP. I often use S3 for storing images, fonts, and other assets for my applications. Some examples include my jarombek.com assets and my global shared assets.
Since Amazon S3 stores files and acts as a filesystem, it can also be used to host static websites.

AWS Lambda Function for MySQL RDS Backups Part I: VPC Infrastructure
When working with Amazon RDS (Relational Database Service) or any other database, creating backups of your data is an important safety precaution. The data of an application is often its most important asset, and if its lost or damaged the app is rendered useless. With RDS, Amazon provides a backup mechanism called snapshots. Snapshots backup the database instance and allow users to restore their RDS instance from a snapshot1.
Internally snapshots are stored in an Amazon S3 (Simple Storage Service) bucket. However, these backups aren't accessible through S3, since the bucket is hidden from the users AWS account2. The only way to see snapshots is through the RDS service. Also, snapshots aren't downloadable and their contents can't be viewed. This poses some serious limitations when trying to test a database backup.

AWS Lambda Function for MySQL RDS Backups Part II: Building the Function
In my previous article I discussed my existing AWS infrastructure and the additional resources needed to automate backups for a RDS MySQL instance using a lambda function. In this article I'll create those additional resources and further explain my design decisions. Finally, I'll test the lambda function and show the backup file in my S3 bucket.

DevOps: Learning Terraform
Ever since I first heard about infrastructure as code (IaC) and Terraform 9 months ago, I’ve been intrigued by what the fuss is all about. I always developed software and nothing more. Digging through Linux or setting up email servers are things I have nightmares about. When told that learning operations is important for developers and warned of the combination of developer and operations (DevOps), I kindly said "no thank you, operations are not for me."
With my first website SaintsXCTF, I was exposed to the world of setting up linux servers to host websites. I set up an Apache web server with DNS routing and stumbled through a Postfix mail transferring agent. I felt very accomplished by all that, but quickly shifted my focus back to developing software. After all, writing code is what I love to do!
With my second website (which you are currently viewing) I started working in the cloud with AWS. I didn't enjoy my time clicking through the AWS UI, picking EC2 instances to start up and configuring S3 buckets. Clicking through a website to configure cloud infrastructure isn't fun, writing code is. If only I could configure all my infrastructure by writing code!
