DEVELOPMENT TO PRODUCTION

hello! I am Wale Ayandiran A Senior Software Engineer with Andela. ✘ A marathoner ✘ Pretend dancer ✘ Likes the idea of food ✘ Advocate of kindness ✘ Why so serious advocate, hence “Heaven will not fall”

What we will be covering ✘ Understanding your code environments ✘ Working in the context of a team ✘ Hands-on

Understanding your code environments

Development Environments Staging / Testing Development Production / Release

What we wish happens during development

DEVELOPMENT Your comfort zone. where you get things done, the tools you use to get the initial work done. You should be very fine failing a lot in this environment without anyone getting hurt. Tools include but not limited to; ✘ Your IDE (VSCODE, SUBLIME, ATOM, ANDROID STUDIO etc..) ✘ Operating system. ✘ Technology used (PHP, JS, PYTHON, GO etc..) ✘ Application Server (optional) ✘ Optionally, your PC (HP, DELL, MAC) etc. Things that happen here; Documentation Automated testing Systems Architecturing Deployment - CI/CD

What truly happens 20% writing coding & hoping it works 80% questioning your life choices

What truly happens 20% writing coding & hoping it works 80% questioning your life choices

When it finally works

A replica of the target environment but not entirely in terms of data and other communication services involved. Mostly for manual testing of the application by Users to see if it works as expected. STAGING Things that happen here; ✘ Q/A testing ✘ User testing ✘ A/B testing ✘ Regression testing

WHAT REALLY HAPPENS IN STAGING

The target environment, the final housing of the application to serve all the users of the application. Product <> Production PRODUCTION Things that happen here (Post deployment / production); ✘ Monitoring & Reporting ✘ Incident Management ✘ A/B testing

PRODUCTION Things that happen here (Post deployment / production); ✘ Monitoring & Reporting ✘ Incident Management ✘ A/B testing So we don’t have a case of ================>

WORKING IN THE CONTEXT OF A TEAM our office

TEAM DYNAMICS Team dynamics are created by the nature of the team’s work, the personalities within the team, their working relationships with other people, and the environment in which the team works. Environment which team work ✘ Team tools ○ Project management ○ Communication ○ Source control ✘ Workflows & convention ○ Style guide ○ Git workflow ○ Dependency manager

Team Tools Project Management ✘ Trello ✘ Pivotal Tracker ✘ Asana Communication ✘ Slack ✘ Microsoft teams ✘ Skype ✘ Whatsapp ✘ Zoom ✘ Google Hangout ✘ Email - Gmail Repository control ✘ GitHub ✘ Gitlab ✘ BitBucket

Team Tools

Workflows & Conventions Style Guide ✘ Airbnb ✘ Google ✘ PSR Git Workflow ✘ PR conventions ✘ Branch Naming ✘ Commit messages Dependency Package Managers ✘ NPM ✘ YARN ✘ Composer ✘ PIP ✘ Gradle ✘ Cocoapods

HANDS-ON Code

What we will be building ✘ A simple API service using XAPI. ✘ Move from development to production using Heroku Apps. ✘ Development to production using docker containers ✘ Auto container deployment strategy CI/CD. ✘ https://github.com/wal ecloud/xapi ✘ https://heroku.com ✘ https://docker.com ✘ https://travis.com

Our development setup ✘ PC OS - (MAC, WINDOW, LINUX etc..) ✘ Programming Language - JavaScript NODEJS ✘ Code editor / IDE - VSCODE

Staging ✘ Temporary deployment ✘ Testing ○ Automated testing ○ Q/A

Production ✘ Hosting platform - (heroku, AWS, AZURE, GCP, Digital Ocean, On-premise server). ✘ Container housing - (docker registry, heroku container registry, Privately hosted registries. ) ✘ Monitoring & Reporting - (Runscope, Bugsnap, Datadog, New relic) ✘ Analytics - (Azure App analytics, Google Analytics etc..)

Let’s review some concepts CI Continuous integration (CI) is focused on automatically building and testing code, as compared to CD CD Continuous delivery (CD), which automates the entire software release process up to production. DOCKER Docker is a set of platform-as-a-service products that use OS-level virtualization to deliver software in packages called containers. Containers Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. Registries A container registry is a collection of repositories made to store container images. A container image is a file comprised of multiple layers which can execute applications in a single instance. Cloud hosting Cloud hosting is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user
