The newer and wider scope is now designing and building web applications as well, including Internet delivered software that can run on mobile apps.Everything can now be a web application. The big vendors are pushing that thinking. With Cloud based servicers, it is easier to add value through useful applications. People are doing more and more things on their phones--not just personal but doing business things on their devices. There is a lot of stuff behind the apps. Additionally, because of the cost of mobile devices, mobile devices are becoming the primary device and they are rapidly increasing. In emerging markets, the mobile device is the primary device. In the US, some people have smartphones, wearable smart watches, tablets and laptops. In other countries, people may just have their mobile devices.Web application now is so much more than just building a web application. There are so many other pieces in terms of delivery, performance, scaling, caching, etc. It is much bigger than just writing some XML and scripts. It is deceptively simple. People may think they can take a quick boot camp to learn how to develop a web application but it really is so much more. If you have to get to 3 million users, you have to think and design a bit differently.By Joseph Eng, CIO, TravelClickINTRICACIES OF BUILDING A WEB APPLICATION
