What to choose for project management if there are more than 1000 of them?

Question

ERP

We provide legal services.
There are many projects, more than 1000.
The projects themselves are small, there are no more than 50 different actions on the project.
All projects are initially long for about 1-2 years, and then it is required to perform 3-4 actions on the project once a year.
It is important to control the deadlines, in case of dismissal of an employee, so that the deadlines assigned to him do not disappear.
What did you look at.
Microsoft Project - designed for large projects, such as building a house, you need smaller ones.
www.easyprojects.net - similar to MP, only web version. Good functionality, but a very strong advantage in favor of projects in programming.
Bitrisk24 - there are projects, but for show. A maximum of 10 pieces can be played normally, then the house begins.
While we use our own development, but I want to find something more relevant.

Answer 1

Spider Project. As they say, copes with very large volumes. I have not tried it on large volumes, but it is wonderful for me to work with finances and project risks. One of the best solutions for UE.

Answer 2

MS Project server, this is a system for medium projects, you can't build a house with it, but it will help to consolidate all the information + there is a web interface.
