AWS Adventures: Part 2 – Infrastructure As Code, Deploying a Microservice

Introduction

 

In the old days, you’d write code and allow another team called Operations (or OPs for short) to deploy it to various servers for testing, and eventually production. Quality Assurance teams would be testing your code from a few days to a few weeks ago on another server.

Developer tooling, infrastructure as a service, and shorter development cycles have changed all that. The Amazon practice of “you build it, you own it” has started to filter out to other companies as an adopted practice. Teams are now expected to build, deploy, and maintain their own software.

Today, I wanted to cover what I’ve learned about automated deployments around AWS. You’ll learn why you don’t need Ansible, Chef, or even Serverless, and instead can use AWS API’s to do everything you need.

AWS Adventures: Part 1 – Lambda

Introduction

At the beginning of October, I started a new project to help my team move a 12 year old application to the cloud. I knew next to nothing about Amazon, or their infrastructure offerings called AWS. In the past 3 months I’ve learned a ton. Today I wanted to share what I’ve learned about Lambdas: Functions you run in AWS.

Also known as serverless architecture.

Functional Programming for OOP Developers: Part 2 – No Errors and Getting Things

Introduction

In my journey to learn functional programming and drink deep of the kool-aid, I wanted to share my latest learnings. Specifically around the quest for no errors and how you get things.

I’ve also just recently applied these same concepts in Python, not just JavaScript, so I’ll mix and match the examples to show how the concepts are universal.

After reading this article, you should understand why errors aren’t helpful embedded in your code & avoiding them is good and why we use functions to get things instead of the old way of assigning variables. Check out the first article if you missed it.

Functional Programming for OOP Developers: Part 1

Yeah yeah yeah, tl;dr; and show me the code, yo!

Introduction

I have been learning Functional Programming over the past year with a friend of mine. We’ve both cut our teeth on finding who to learn from, what articles are useful, and what actually translates into your day to day programming job. I’ve also learned a lot of natural problems that arise as you start a new project from scratch with an OOP background, or if you’re refactoring some OOP code to be more functional.

In this article, I wanted to share some of what I learned. Specifically what functional programming is, why it matters, how to use pure functions and list comprehensions in the real world. While I use JavaScript in this article, I’ve learned that the concepts and libraries supporting it are available in many programming languages.
