- High availability- SPAM check etc up-to-date- No local maintenance needed

- Project-related websites @sites.google.com (e.g. EALAN)- High availability- High performance collaboration with international

partners- E- and distance-learning must consider bandwidth and

access limitations - Avoid streaming-only e.g. for MOOCs- Use DRM carefully
