The world is rapidly moving toward the cloud and away from traditional IT systems. Browser-based security using https has evolved and is now accepted by customers as "secure." In recent years, many browser security flaws have been identified and fixed. A major industry shift occurred when some browsers were created and maintained as open source projects. This helped increase security thanks to a community of engineers reviewing and updating the code on an ongoing basis at no cost. Since some current browsers are not controlled by private corporations, this also creates a key element of trust.
Getting to this point has been a long journey, with a number of important industry and technology events helping to make cloud computing possible and secure.
