Let's talk about API, cloud services, and how those things can improve your business from different perspectives.
APIs, from one side, are omnipresent. They have become one of the easiest ways to connect servers and exchange data between projects and services.
Before, developers built closed systems, and if you wanted to have a new feature - you had to build it yourself. You also need to release it, test and do everything else, that nowadays we are calling "software development".
But we don't live in caves, do we? In ancient times, you had to do it all: hunting, building, guarding your territory, and counting how many grains you had for winter. Later, people invented an open market. If you are better at something, like hunting, you'll sell meat that is left to someone else, who is, for example, more skilled at collecting herbs and can help you to reduce your headache.
From that time, specialization starts to be necessary. Education and skills have a real value that you can trade. We are still moving in that direction. If you spend a lot of time mastering your skills - you become a well known professional. If people want to use your skills, they will want to pay as much as you want. If your expertise and quality of work are worth it.
If you've created some Scarcity - I'll have to pay you as much as you request...(Thank you, Yegor Anchishkin, for teaching me what Scarcity means.)
Instead of building a buggy payment accepting tool, you connect to Stripe and pay commission from transactions. Now your customers will trust you more because Stripe has substantial Brand Value and guarantees the security of the payment act. So by paying them, you get like +100 to armor.
Building products today related to working with cloud and cloud service providers. "Localhost" doesn't work anymore. I'm not a pro here, so it's better to hear an opinion and insights from the best experts.
