Messaging and collaboration services are far from being mere commodities for most organizations. Rapidly increasing user demands have led to custom deployments that are not being matched by cloud suppliers. These suppliers are challenged to meet specific needs for security, content control, and application integration. The evolution of hybrid messaging and collaboration models in areas such as message hygiene, archiving, mailboxes, and unified communications are disrupting this space, leading to new and optimized delivery models that are cheaper and can be custom built to client requirements across user profiles in various industries.
