  • 1. Cloud Computing realitatea de dincolo de BUZZ word Alexandru Lăpuşan Zitec CEO & Founding Partner

    • Cloudul este bun
  • 3. Morala
    • Cloudul este bun
    • Dacă este folosit
    • cu cap
  • 4. TOP 5 motive greşite
      • Toată lumea vorbeşte despre cloud-computing
      • Acţionarii / investitorii / clienţii vor fi impresionaţi
      • Am auzit că ar fi mai ieftin
      • Dacă e în cloud dispar problemele de scalare/uptime
      • E uşor să anticipezi şi să calculezi costurile
  • 5. AWS Tips & Tricks
      • O instanță nouă nu pornește instantaneu (2-3 min)
      • Proceduri deployment
      • Limitări raportare (band-out)
      • Mici probleme cu ELB headers
        • HTTP nu implementează  PUT
        • TCP pierde informații (remote addr)
      • Utilizare corectă Elastic IP / ELB
        • DNS 
        • Trafic "străin" spre instanțele noi
  • 6. Costuri in Cloud (AWS)
      • Computing hours (EC2, SDB, RDS, alte tipuri de instanta)
      • Stocare date (S3, SDB, ELB, RDS)
      • Band-out (S3, SDB, EC2, CF etc)
      • Band-in (S3, SDB, EC2, CF etc)
      • Numar de tranzactii (ELB I/O, RDS, etc)
  • 7. Slide cu numere
      • Costuri AWS EC2 $0.03 - $2.48 / h 
        • Adica $20 - $1,785 / luna + band-in & band-out
      • Costuri Azure computing ($0.05 - $0.96)
      • Cum stocam 180 GB?
        • SQL Azure 4 x 50 GB = 4 x $500 = $2,000
        • AWS RDS $0.10 / GB / lună = $18 + computing $
      • Cum stocăm 1GB
        •   SQL Azure $10
        • AWS RDS  $1 + computing $ 
      • AWS DB Computing $0.12 - $2.96 /h   =  86$ - $2,131 /lună
  • 8. Calculul nu este simplu
  • 9. Începutul este totuşi simplu
      • Amazon (@Sign In)
        • 750 hours of EC2 running Linux/Unix Micro

        • 15 GB of band-in & 15 GB band-out
