We have categorised mostly all services into technologies that are broadly used globally. These technologies can be further extended to work with each other or work together.
A distributed public ledger used to store records and show proof of work without the involvement of a central authority. (Disclaimer: It's really not as interesting as its hype would suggest)
Tracking, collecting, streamlining, and storing of data. This data is processed into information which, in turn, is represented in a format that is either easy to visualize (for humans), or easy to customize (for software)
A way to analyze reams of data with or without human intervention, with ML techniques such as neural networks, deep learning, etc. This can be further supplemented with true AI tools such as causal models and bayesian analysis
For complex real-world systems with multiple points of input of multiple different kinds. Set up a network of sensors, displays, and processing which is optionally connected to your devices, and/or The Internet.
Bypass infrastructure requirements by cloud hosting instead of having your own server. Easily scalable, and increasingly specialized; focus on your business goals instead of operations or maintenance
Includes websites, web apps (yes, those are two different things), mobile apps, REST APIs, chat systems, media streams. Just about anything that connects to The Internet falls under web development.
When there is so much distraction, it is easy to get lost. UI/UX is to create a guiding system that not only helps people to navigate the maze but also gives a feel of joy and ease. This is not only important but rather essential.
When the digital world is filling up with so much noise, it becomes imperative to ponder about how exactly we want people to know us and interact with us. Digital marketing aids to glean every last bit of data to use to our advantage to meet the end goal.
