Open Cloud BBQ - Nano Server

•
– zašto moram ponovno pokrenuti server nakon zakrpe za komponentu koju
ionako ne koristim?
– ako je i potreban restart, to ne smije dugo trajati!
•
– (pre)dugo se instaliraju i konfiguriraju!
– prijenos predugo traje i previše opterećuje moju mrežu!
– njihovo spremanje troši puno prostora!
• OK, postoji deduplikacija… ali… 
•
– manje resursa za OS = više virtualnih strojeva po hostu!
– sa više virtualnih strojeva po hostu = manji troškovi, veća efikasnost!

Server Roles/Features

•
– zakrpe i restartovi ometaju rad i servise
– vrlo velik broj servera * velika potrošnja resursa (OS) => ZASTOJI!
– provisioning velikih host imageova (gušenje mreže)
•
– Cloud-in-box (1-4 rackova sa System Center & Windows Serverom)
– treba skratiti vrijeme podešavanja i instalacije
– zakrpe i restartovi ometaju rad i servise
– nepotrebno trošenje mrežnog bandwidtha
– restartovi – compute host ~2 minute, a storage host ~5 minuta
… i onda se „desio” cloud!

Što dalje?

Zaključak
Ne radi i vjerojatno nikad neće baš sve raditi na
Nano Serveru, ali i on ipak ima svoju primjenu!
(nema razloga da ga ne koristimo tamo gdje možemo… ili ima?)
P.S. Krajnje vrijeme je za (na)učiti PowerShell… 
