The Future of Database Development DevOps is a hot topic in today’s software development world. However most of the knowledge and experience with DevOps is based around application software and ignores the database. We will examine how the concepts and principles of DevOps can be applied to database development by looking at both automated comparison analysis as well as migration script management. Automated building, testing, and deployment of database changes will be shown. Steve Jones Editor, SQLServerCentral Redgate Software @way0utwest

Agenda Who am I? Getting Started on a Database Project Branching for Experiments Fixing Mistakes Easy Continuous Integration The Administrative side of containers

Getting Started I got a new gig… They're letting me do web development!!!! I don’t want to worry about databases I don’t have SQL installed I have cloned the source code

SQL Server Shared Account database PostgreSQL Todo database

I get a login to Spawn (DBaaS)

Demo Getting a new developer started Nothing installed Cloned project Spawn login Yarn start

Branching A typical concern is I want to try something However, I don’t want to disturb other’s work Branches allow me to experiment and commit separately I can discard these, recreate these as needed, which means I want the database to do the same. I can merge in changes that work

Demo Branching - Checkout new branch - Getting a new data container

Oops, I did it again Often, I make some mistakes in development Usually, I can’t remember or don’t know the code to reset the database This is frustrating because app code just resets

Demo Reset Delete/change data Spawnctl reset data-container

Recap DBaaS removes the need to manage the server component Containers provide a known, consistent starting point Integration with easy deployment as a part of app config Reset can speed up testing of data issues Questions?

Continuous Integration

Independent Validation with CI We want to check changes Avoid the "it works on my machine" I want my CI process to be simple

Demo Continuous Integration

Image Building and Maintenance

Building Images DBA needs to help manage schema and data in the image How do I create a new image? Make changes and graduate Update a version and distribute out

Demo Container Management Manually Automated build spawnctl save data-container demo-account-steve spawnctl graduate data-container demo-account-steve --name steveimage --team red-gate:sharks --tag v1 --revision rev.0 Container Management Manually Automated build

Summary DBaaS is the future Containers make development easy(-ier) Handle branching easily for experimentation Reset immediately Parallelize testing with a database Lightweight and reduce setup DBAs still have control
