SMILE . This approach has led to a range of white papers covering various fields of application: Content management (2004), portals (2005), business intelligence (2006), PHP frameworks (2007), virtualisation (2007), and electronic document management (2008), as well as PGIs/ERPs (2008). Among the works published in 2009, we would also cite “open source VPN’s”, “Firewall open source flow control”, and “Middleware”, within the framework of the WWW “System and Infrastructure” collection. Each of these works presents a selection of best open source solutions for the domain in question, their respective qualities as well as operational feedback. As open source solutions continue to acquire new domains, Smile will be there to help its clients benefit from these in a risk-free way. Smile is present in the European IT landscape as the integration architect of choice to support the largest companies in the adoption of the best open source solutions.

This comes as no surprise given the rich and varied range of open source solutions available today. Smile has been regularly publishing white papers presenting the extraordinary depth of these OM solutions since 2004: content management in 2004, portals in 2005, business intelligence in C 2006, virtualisation in 2007, electronic document management and ERPs in 2008, open source . VPNs and firewalls in 2009, e-commerce and corporate social networks in 2010, and so on. A total of 22 documents have thus been produced and are available for free to download. OSS Each text presents a selection of the best open source solutions for the domain in question, - outlining their respective strengths and providing feedback on real life experiences in using these tools. Yet one thing was missing: a central repository containing the best open source solutions on the market, which could be used to guide and orientate decision makers toward benchmark SMILE . solutions. We have received many requests for such a guide, particularly from IT Departments. The gap has now been filled with this white paper, which presents more than 170 products in 40 enterprise software domains. All product types are included, or nearly all - this paper does not, for example, look at workstation or “office automation” applications like Firefox, Gimp WWW and LibreOffice - with a summary presentation (creation date, licensing, technologies, etc.) and an assessment of each based on six standard criteria. This document was developed by more than 30 of our top technical, functional and business specialists. We hope that this white paper will be of use to you. Before launching into the following 200+ pages, we recommend you read through the next section, which describes our analytical methodology and lists our suggestions for deriving maximum value from the guide. Enjoy! Please feel free to share your opinions and assessments of the products presented in this white paper with us. Likewise, do let us know if there is a solution you would like to see included, which we have omitted.
