When thinking about your own webpages, or services offered digitally, many businesses often do not think about scalability. Because it is invisible. You do not concern yourself that the web service is scalable as long as it is working. Unfortunately, this lack of ability to react, or more simply - handle the workload, traffic, capacity, and agility might be really painful.
Imagine a huge airport’s web service where you can book a ticket, check flight’s departure, perform self-checkin and just find useful information for traveling. AND suddenly there are too many users at the same time using the service, and everything is jammed. People become angry, frustrated, sometimes scared. The helpline is already having a hiccup and all the helpdesk staff is dreaming about dropping it all and moving to Tibet. But this is only the first stage. Later, after the communicational chaos there comes the Social Media buzz and the press publications. All the positive feedback gained with years of hard work disappears in a few minutes. Then comes the most terrible payoff - lawyers with summons. But wait, the airport itself was operating - planes were departing and landing, passengers were checked-in, luggage was distributed… It’s just the web service.
