Infrastructure 100 Solutions

The “Infrastructure” dimension is certainly the best represented in the field of open source tools, with hundreds and even thousands of available solutions. And it is from this dimension that open source projects are born. Many have reached such prominence that they are close to being household names: tools such as the Apache HTTP server, the Nagios supervision tool, and the Linux line of operating systems. These projects and the many others included in this dimension lay the foundation for a sound infrastructure capable of hosting the best applications under optimal conditions.

Development and intermediate layers 133 Solutions

As its name indicates, the "Development and intermediate layers" dimension covers all the solutions useful to development functions, typically found between the Infrastructure and Application layers. It is also particularly well equipped with open source products.
Beyond applications like CMSs, e-shops, document management solutions, etc., there is a broad panel of open source development solutions, such as Eclipse and frameworks like Symfony and Django. It should be noted that some tools, like directories and databases, could have been classified in the Infrastructure dimension.

Applications 118 Solutions

The "Applications" dimension includes all the solutions commonly used by companies' end users. They typically offer carefully developed interfaces that are far removed from the command lines typically available in tools in the “Infrastructure” dimension. The vast majority of these tools are developed by vendors, unlike infrastructure tools, which are primarily community based. These vendors have chosen the open source model for publication of their solutions. Their economic models are mostly based on support, and even warranties, for the products in question. These tools have played a key role in the widespread adoption of open source technologies, by offering quality applications with very broad scopes. There are almost no categories now that do not include at least one open source option. Even in very specific domains like library management and business intelligence, open source solutions are available.
