With the wrong architecture, APIs can be a bottleneck to not only your applications but to your entire business. Bottlenecks such as downtime, low performance, or high application complexity, can result in exaggerated infrastructure and organizational costs and lost revenue. Serverless APIs mitigate these bottlenecks with autoscaling capabilities and consumption-based pricing models.
Once you start thinking of serverless as not only a remover-of-bottlenecks but also as an enabler-of-business, layers of your application infrastructure become a source of new opportunities. This is especially true of the API layer, as APIs can be productized to scale your business, attract new customers, or offer new services to existing customers, in addition to its traditional role as the communicator between software services.
Given the increasing dominance of APIs and API-first architectures, companies and developers are gravitating towards serverless platforms to host APIs and API-first applications to realize these benefits. One serverless compute option to host API’s isAzure Functions, event-triggered code that can scale on-demand, and you only pay for what you use. Gartner predicts that50 percent of global enterpriseswill have deployed a serverless functions platform by 2025, up from only 20 percent today. You can publish Azure Functions throughAPI Managementto secure, transform, maintain, and monitor your serverless APIs.
