Google has just updated its Google Apps launcher.
Before the update, Google had all the apps listed in the top of the page as pictured below.
After the update, the apps no longer appear in a toolbar on the top left. Rather, they are in a grid-like structure on the top right of the page, next to your account name and picture. To access your Apps (calendar, emails, drive, etc) you can click on the 9 small boxes to access a drop down list as shown below.
