The shortest presentation of my life - and an incredibly easy sell with a quick over-view of serving images with GridFS

1. STORING AND SERVING IMAGES WITH
GRIDFS

2. z
MEDIA STORAGE & SERVING
( without using a file-system )

3. z
WHY DO FILESYSTEMS SUCK ...?
( at serving media on the web )

4. POOR AT SCALING
( with tedious back-ups and I/O bottlenecks )

5. POOR METADATA
( lacking built-in meta storage and data queries )

6. STRICT CONVENTIONS
( naming and directory limits cause poor reliability )

7. GRIDFS ALSO USES REPLICA-SETS
( all media backed-up and load-balanced in chunks )

9. EXAMPLE PHP
CODE
GETTING IMAGES OUT

10. www.your-domain.com/images/tron.jpg
( assuming .htaccess is redirecting within folder )
// Get Filename
$slug = $_SERVER[‘REQUEST_URI’];
// Define Database
$db = $m->$options['db_name'];
// Get GridFS
$grid = $db->getGridFS();
// Get Image
$image = $grid->findOne(
array("name" => $slug)
);
// Display Image
header('Content-type: '.$image->file['type']);
echo $image->getBytes();
