Think of any established industry. Right now, at least a dozen beginners are trying to blow up a torpedo through its shell, and many have a decent shot at it.
● Fintech startups are trying to disrupt the banking industry raised $ 34.5 billion in 2019, According to Business Insider;
● InsurTech startups who want to accelerate the insurance industry saw a 71 percent increase in funding during one quarter in 2020, according to Forbes;
● The growth of HealthTech startups, which are opening new paths in the healthcare industry, accelerated, and Venturebeat announced The pharmaceutical and biotechnology industry is very hot.
However, many of these startups are not trying to replace established competitors. Instead, they plan to collaborate with them by focusing on improving one or two areas of banking, insurance, or healthcare and selling their services to larger companies as application programming interfaces (APIs).
API-based companies are seeing momentumAccording to TechCrunch, and as APIs become the primary product to be commercialized – as they become the connecting fabric between high-tech startups and companies looking to modernize against their own internal slowness – finding the best API the tool starts. Many API-based companies place the API gateway at the top of the list.
The API gateway provides the hub Vanishing point which API consumers connect to for a variety of background services. It’s kind of like a shopping mall in the API world: a centralized place that hosts many APIs. Instead of having to configure their applications to connect to multiple endpoints, API consumers only need to connect to the API gateway to gain access to all the services behind it.
As all messages pass through the gateway, it becomes a matter of course to add functionality that covers the service offering. For example, the gateway adds TLS Encryption secure transported messages; it is layered with tracking, allowing the API provider to track usage and see which APIs are getting bets. Other features include Price cap, Authentication, cache, and server health check. Incorporating these features into the API gateway is much like getting them for free because it shortens the development time that is otherwise required to build these same features into backend applications.
The API gateway is really just a load balancer enhanced with the security, visibility, and speed-limiting features that API-based companies find desirable. Modern load balancing devices have these improvements – they are already being baked – and companies looking to reduce development time find this very convenient.
Judging from the discussions in the developer community, it appears that API developers are looking for similar features that they want for traditional web applications, but with some caveats. They need authentication, but it must be ID-based or API key based on human login. They need a cache, but it has to be short-lived because the data is updated frequently. They need price limits, but it must take into account the level of subscription to the consumer API. Because these needs are universal – they are not entirely new in the world of load balancing – they come from the beginning. In other words, these are solved problems.
The API gateway model is also popular in the ultramodern technology stack, such as Kubernetes. In Kubernetes, micro-service architecture has found a fertile ground for companies to build complex systems consisting of many independent and extreme redundant independent services. However, UI applications need a way to call these services cheaply, for example, without putting a full-scale cloud load balancer in front of each.
For this reason, engineers who design Kubernetes Chassis defined the Ingress Controller concept, which is now a solution for directing traffic to the Kubernetes cluster. The whole Ingress Controller model is really just an API gateway model. Today, you will find several Ingress Controller implementations and choose the one that suits your needs.
As APIs continue to serve as core products sold by startups, they will continue to leverage API gateways as the backbone of their offerings.
