Application modernization is all about empowering currently-running applications to meet business goals and customer expectations, which are constantly evolving. There are a number of digital technologies and artificial intelligence (AI) algorithms emerging, which are evolving quickly. We have scores of edge/digitization technologies, such as sensors, actuators, implants, wearables, stickers, tags, codes, chips, controllers, smart dust, specks, beacons, and LED elements, for creating digitized entities out of physical, mechanical, and electrical systems. That is, our ground-level physical systems become digitized, joining mainstream computing.

A bevy of digital technologies (cloud, mobility, social, IoT, and analytics) are gathering a lot of attention because they're capable of bringing in a dazzling array of digital innovations, disruptions, and transformations. With the maturity of AI algorithms, the domain of digital intelligence is gaining prominence in making sense of digital data. Thus, the real digital transformation involves digital and digital-intelligence technologies. Also, there are outdated and old-fashioned applications and technologies aplenty. To attain a real digital transformation, these old, yet currently-running, applications have to be modified using modernization and migration tools. The hugely popular digital technologies that we've mentioned have to be leveraged to bring advancement to legacy applications.
