APIs provide a way to simplify development, reduce costs, and create more flexible and scalable applications. Much of today’s development relies on APIs – in the integration of third-party services, in the communication between microservices, in mobile app development, and in other use cases. Some APIs even exist as products themselves for customers to use.

Browser instrumentation refers to collecting and analyzing data about a user's interactions with a web browser. This type of instrumentation involves using specialized tools and techniques to gather information about how a website is being used, such as page load times, network requests, and user interactions. The data collected through browser instrumentation can be used to improve website performance, identify and troubleshoot errors, and gain insights into user behavior.

OpenTelemetry is an open-source observability framework that provides a vendor-neutral and language-agnostic way to collect and analyze telemetry data. This tutorial will show you how to integrate OpenTelemetry on Kubernetes, a popular container orchestration platform. Prerequisites.

OpenTelemetry (OTel) is an open-source observability framework that provides a standardized way of collecting, processing, and exporting telemetry data (metrics, traces, and logs) from distributed systems. It was born by a merger between two previously separate observability projects, OpenCensus and OpenTracing, and it is currently maintained by the Cloud Native Computing Foundation (CNCF).

Adopting a distributed tracing solution to make an application more observable and maintainable is one of the most common key initiatives modern R&D teams have on their plates currently. With the move to microservices architectures, development teams are finding that it’s taking them longer to build applications due to tasks that are growing in complexity.

OpenTelemetry and DataDog are both used for monitoring applications. While OpenTelemetry is an open source observability framework, DataDog is a cloud-monitoring SaaS service. OpenTelemetry is a collection of tools, APIs, and SDKs that help generate and collect telemetry data (logs, metrics, and traces). OpenTelemetry does not provide a storage and visualization layer, while DataDog does.

Distributed Tracing, combined with end-to-end monitoring, lets organizations keep track of their business transactions and receive alerts when anomalies happen. End-to-end monitoring benefits business users and functional administrators more than developers and technical administrators. Nowadays, for developing integration solutions, microservice architectures are becoming the norm. A solution based on such an architecture relies on different services that shape a specific solution together.
