In the first part of our series on Building, Deploying, and Observing SDKs as a Service, we delved into the world of APIs and successfully deployed our own REST APIs by wrapping the existing pet store APIs. Now, it’s time to take our journey further and unlock the true potential of SDKs. In this second part, we’ll explore how to build an SDK for the pet store API using the OpenAPI spec and the OpenAPI Generator project.

Health checks for cloud infrastructure refer to the mechanisms and processes used to monitor the health and availability of the components within a cloud-based system. These checks are essential for ensuring that the infrastructure is functioning correctly and that any issues or failures are detected and addressed promptly. Health checks typically involve monitoring various parameters such as system resources, network connectivity, and application-specific metrics.

Just how in demand is serverless computing, really? Popularized by Amazon in 2014, serverless computing had already clinched the title of the highest-growth public cloud service as early as 2018. With its total market value shooting past the USD 9 billion mark in 2022 and projected to hit a jaw-dropping USD 90 billion by 2032, it’s safe to say this relative newcomer is doing quite alright for itself.

Serverless, as you may already know, is a cloud computing model where the cloud provider dynamically manages and allocates resources to execute code without the need for server provisioning or infrastructure management on the developer. This article overviews serverless observability, monitoring, and debugging, based on distributed tracing and OpenTelemetry (OTel).
