Hello,
We are planning a migration from UNIX (HP-UX, AIX, Solaris) to Linux on AZURE.
I know it sounds like extremely complicated 
That's why we need your help 
We are at the beggining of stage.
We need to categorize the types of applications (software) that generally runs on UNIX systems.
For the moment, we can list Databases, Middleware, SAP, etc.
Could you list other types of applications?
Other names of most-used applications ?
Is there any tools for the migration?
Thanks
It doesn't quite work that way. Most applications that run on UNIX have a linux version. Simply put: no linux migration path == lost software business. Except in the case of legacy stuff written back in the 1980's.
Linux is a derivative of UNIX, like earlier flavors of UNIX were derivatives System V UNIX that became AIX, Solaris, and so on. The difference here is that there are POSIX standards nowadays which means, in practical terms, that porting your homegrown code to Linux is usually feasible. Often pretty close to painless.
There are some products that are OS specific. You would get a lot better answers if you told us what applications you have running now and what you want to do. A list like you asked for will get you nowhere.
Example: oracle works well on UNIXes and Linux. In fact, Oracle appliances like EXADATA machines run Linux - for other UNIX types.
Specifics are needed here.
You are asking us to enumerate the universe. Not only would that be a lengthy undertaking, most of the things we list would be things you probably don't have. Only you can tell us what you do have.
A good start would be to get a list of all running system services. From there you can look into what each of them are configured to do.
Hi.
I would guess that it depneds on your business -- for a start, see Application software - Wikipedia
