Advantages and Disadvantages of AS400


Hi Guys, 

One of my friend over Linkedin want to know the advantages and disadvantages of AS400. So thought of sharing the same.
Advantage of AS400
The main advantages of AS400 over other are
 1. Stability
You would have sometime re-booted your desktop twice or thrice a day. But can you afford to do the same with your Servers. I know few organizations where IT admin are not aware of AS/400 Machine reboot date
2.        Integration
Using AS400 you need not worry about integration of database, Programing languages to use
Will the security system work with the database and will the database work with the operating system, etc are questions that do not apply to AS/400. It is amazing how much time can be invested in making these things work together, but on iSeries (as with AS/400 and S/38), the question is simply irrelevant.
3.        Security
OS/400 is an object orientated operating system it is virtually immune to viruses.

Disadvantage of AS400
To count disadvantages of AS400, there would be less. Still to count, below are the few disadvantages of AS400
1.       Cost - 
          The hardware costs for NEW machines are significantly higher than other platforms.
2.       Developer Resource – 
        Nowadays RPG Developer are a rare breed of developers which comes with high Dollar value as compare to other development languages like JAVA
3.       Mindset - 
        The biggest problem is mindset of people. An AS400 is seen as a clumsy box capable of only green screen applications and suitable only for large businesses having large cash transactions. This is simply untrue. The box needs almost no supervision. All you ever have to do once it's loaded up is change the backup tapes. BUT, it is perceived as old technology when in fact it is probably more robust and cutting edge than most of it's competitors.
