@shahadarsh bit.ly/envs-dod-philly Agenda • Challenges affecting Developer Productivity • Real examples • Use cases for Ephemeral Environments • How to implement Ephemeral Environments • Environment as Code • Demo (if we have time)

@shahadarsh bit.ly/envs-dod-philly Show of Hands

@shahadarsh bit.ly/envs-dod-philly Caution!

@shahadarsh bit.ly/envs-dod-philly Challenges affecting Developer Productivity Troubleshooting mysterious bugs Replicating Environments is a pain Con fi guration Drift Rising Cloud Costs

@shahadarsh bit.ly/envs-dod-philly Real examples • Devs waiting weeks for a new environment to be ready • Tearing down environments is not easy • Dev teams have monthly cloud budget

@shahadarsh bit.ly/envs-dod-philly What is an Ephemeral Environment? Ephemeral environment (dynamic or short-lived environment) is the idea of provisioning an environment on-demand when needed and then destroying it afterward. It is a useful technique to test your IaC and applications running on it without a need to keep it running all the time.

@shahadarsh bit.ly/envs-dod-philly Use Cases for Ephemeral Environments

@shahadarsh bit.ly/envs-dod-philly Developer Environments • Shared Environments • Ability to create new Development environment • Tear them down when not needed

@shahadarsh bit.ly/envs-dod-philly Test Environments Test Product Features Performance/Load testing Troubleshoot Production Issues

@shahadarsh bit.ly/envs-dod-philly Environment as Code

@shahadarsh bit.ly/envs-dod-philly IaC vs EaC Infrastructure as Code Automates various Lego Pieces 
 (i.e. Infrastructure Resources) Environment as Code Automates how those Lego Pieces 
 are connected to make up a Lego Toy 
 (i.e. Entire Environment)

@shahadarsh bit.ly/envs-dod-philly Environment as Code Environment as Code (EaC) is an abstraction over Cloud native tools that provides a declarative way of de fi ning an entire Environment. It has a Control Plane that manages the state of the environment, including relationships between various resources, Detects Drift as well enables Reconciliation.
