Direct answer sa query mo boss: For cloud computing.
Kung medyo malabo, ang cloud server ay parehas lng sa physical server, ang kaibahan nga lang, ang cloud ay ma-access mo thru the internet, in which yung physical server obviously nahahawak at nakikita mo.
Example sa cloud computing eh yung Google services like Gmail, Google Docs, Google Drive and among other services.
AWS or Amazon Web Services is one of the many examples of Cloud Computing. Daming purpose neto, pwede mag host ng database, pwede services like email, file hosting, pwede din gamitin ang computing power gaya ng ginagawa pag folding (data crunching)..
