2.Buildpacks
What? How? When? Why?
“Buildpacks examine artifacts
to determine what dependencies to download
and how to configure applications to communicate
with bound services.
What they do?

Special thanks to all the people who made and released these awesome resources for free:▧ Presentation template by SlidesCarnival▧ Photographs by Unsplash▧ Backgrounds by Pixeden
SlidesCarnival icons are editable shapes.
This means that you can:● Resize them without losing
quality.● Change fill color and opacity.
Isn’t that nice? :)
Examples:
Now you can use any emoji as an icon!And of course it resizes without losing quality and you can change the color.
