How Microsoft Uses C++ to Deliver Office (and More) Across iOS, Android, Windows, and Mac, Part II

Log in to save this to your schedule and see who's attending!

What does it take to target multiple major mobile devices (as well as traditional environments) with portable, efficient, single-source code? This talk demonstrates architectures, techniques, and lessons learned rooted in actual experience with using C++ to deliver several major cross-platform projects across iOS, Android, Windows, and Mac: Microsoft Office (Word, Excel, PowerPoint, OneNote) and the SQL Server PowerBI. Each presents a different case study: For example, Office already used C++, whereas PowerBI was originally written in Silverlight and then rewritten in C++; Office is a set of user-facing apps, whereas PowerBI is a system component. Although some of these are demanding first-tier “Cadillac” applications, we expect this experience to be a model for the future as more and more apps fall into this category and use C++ to target many popular platforms from (mostly) a single source base. This talk will cover the following key topics and tradeoffs: Rich vs. reach, including access to latest OS features (e.g., iOS 8 additions) and hardware features (e.g., vector units, GPUs). Consistency of functionality. Client code vs. server/service web code. Sharing vs. quality, including dialing appropriately between more shared code and high quality code. Drawing the line between the bulk of C++ code and interfacing with non-C++ for UX and PALs (platform adaptation/abstraction layers) for target-specific user interface and system services. Architecting PALs, including why “mini-PALs” rather than an “über-PAL.” Forces “doing the right thing” and good architecture with composable components. How C++ enables things not feasible using other technologies. Velocity and enabling faster cross-platform development and deployment. Cost of maintenance, including time, size, and complexity (both breadth and depth). And, last but not least, developing in a single modern C++ source base built with different evolving C++ compilers, including VC++ and Clang/LLVM.
