Advantages..

1. Performance :

Mainly because it is optimized to workwith the SPARC, it gives better performance than the

other alternatives available. You would find many ofthe Sun's server solutions running with the Solaris OSsuch as Netra series.

2 . POSIXcompliant environment: Solaris can beconsidered to be compliant with the POSIXenvironment which means a standard programminginterface for developers.

D

isadvantages..1. Uncompatible : It is not recommended to run Solaris on other

architectures such as Intel, AMD. It is possible to install Solaris onIntel however, the performance would degrade considerably since

Solaris cannot make use of Intel that efficiently.2. Lack of good GUI : Solaris does have GUI support - Common

Desktop Environment, OpenWindows etc. but they are far wayfrom the other GUI environments seen in Windows orMac.

3. Costlier: With other cheaper alternatvies such as Linux available, it

proves to be costlier to acquire a license of Solaris. Since it isintended to be used on SPARC so the end user often ends up inbuying the hardware as well.
