Razvoj distribuiranih web sustava Goran Peretin @gperetin
student @ voditelj razvoja @ CTO @
• Bunkhouse – sustav za obradu, spremanje i distribuciju video
datoteka • 1 datoteka = 1 – 250GB (+ obrada!) • Python, Linux
None
Amazon EC2 RedisToGo Amazon EC2 ... Amazon S3
• - Skup • + Jednostavan deploy • + Integracija
s vanjskim servisima • +/- Amazon EC2 • OK
• - Stabilnost – • - S3 Torrent streaming
– limit na 75KB/s? • - File size limit 5GB (multipart) • - S3 – SKUP – Outgoing transfer – Requesti • + S3 – Disk import • SREDNJE
• + Python, Ruby, Java SDK • - Dokumentacija nije
up to date • - Zatvoren razvoj (ne primaju patcheve) • + Intuitivna integracija za korisnike • OK
• + Vrlo jednostavna integracija • + Odlična dokumentacija •
+ Dobar API • +/- S3 integracija (iako “zaborave” spomenuti detalje) • SUPER
• - Kompliciran API (upload videa – 6 API metoda)
• - Loša integracija Vimeo PRO – neki featurei nisu dostupni kroz API • + Jednostavan embed • SREDNJE
• Skup • Malo prostora • Limitiran broj konekcija •
LOŠE
• Decoupling • Log everything!!1 • Papertrail – log management
• Nikad previše dashboarda (iako 1 je idealno) • Testiranje – teško • Nakon 3 mjeseca...
Amazon EC2 RedisToGo Amazon EC2 ... Amazon S3
Otprilike...
...
storage + transfer EC2 + S3 + Heroku Hetzner 2TB
+ 1TB $559 $500 5TB + 2TB $1179 $830 20TB + 10TB $4389 $1555 Zašto? ...iako • više održavanja • sporije • Dropbox samo u SAD – 5.5MB/s na 3.5MB/s • AJAX heavy web aplikacija • Transfer sa i na Zencoder • But... It doesn’t scale?
Hvala!
