windows Server 2003 in 2017

Hello Experts,
I need to explain what are the main disadvantages
of using windows server 2003 as a virtualbox machine 4Gb RAM

Besides not having any support since 2015
it is 100% compatible with latest dot net visual Studio ? or latest Java ?
and latest MySQL database?

 need to prevent our team of working twice because I did not check on this.

What other services, facilities will be lacking ?

And finally what would be your best VM configuration for a database that handles around  1 Gb data  with 10 local connections over the LAN ?

How much RAM would you ask for your VM server and how many processors ?

Best regards,

No updates, security is lacking, it cannot be patched any more.

Why do you need to keep it?

Is for sure not supported on latest Java nor Visual Studio nor its only good if you have legacy application that you need to keep them going while in the meantime you are migrating them to newer platforms....

Now we have tested it over RDP and its ie browser is obsolete, and makes it very difficult to download, update or to do basic simple tasks.
so I think this can become a major issue when our team starts installing apps and working on it.

It costs money to maintain products compatibility.  It costs money to pay the programmers and support personnel. In order to maintain compatibility with older technologies, sometimes newer technologies cannot implement enhancements that allow newer, better things.

2003 is, as you pointed out, 14 years old.  Since Microsoft decided it was no longer supporting 2003, you CANNOT EXPECT them to test newer technologies (like Windows 7 or Windows 10) to ensure they still work with 2003.  While I doubt they are actively trying to "break" compatibility, because they are likely not testing, you cannot know when a new update to Windows 7 or Windows 8 or ANY version of Windows that's still supported will cause things not to work.

Similarly, the makers of Java, if they know Microsoft is no longer supporting it, would likely stop being (very) concerned with their product still working on that old system.

Bottom line, you almost certainly will not know if and when something breaks because the software is so old.

You need to upgrade!

You really and truly need a different IT Support person. You are laying out disadvantages on top of what we have said. Server 2003 is dead and it is really time to move on.  You do not need to make a VM of Server 2003 for business use, just upgrade and use newer server technology.

This a bit tough question because a lot of factors should be considered....the most demanding of all is what applications you have and what you need to use the server for...
For example in my Company i have a very old ERP that worked great on XP....failed miserably on Vista...worked ok on Windows 7 and has issues (speed of grid rendering) on Windows if it was to put a suggestion it would be a Windows 2008 R2 server...
Another example....when you do file operations on Windows 8.1/10 you need more permissions than windows 7 so when i was developing in Java that did posed a few issues...
If you need VS 2017 & MySQL then the best bet is at least 2012 R2 server or  2016 ....if you need some older features then 2008 R2 is a good allaround choice
