Why do I recommend the Spring Framework to my customers

Is Spring the new legacy as quite a few people tell you on their blogs? I disagree on many levels. Throughout this session I will holistically detail on many levels without any polemics why I do recommend using the Spring Framework and it's ecosystem. Aspects that will be covered include: operational impacts, ecosystem, coding and road maps.
