These services allow users to stream or download content across a broad category of devices including mobile phones, laptops, and televisions. However, some restrictions are in place, such as the number of active devices, the number of streams, and the number of downloaded titles.

We described the tools and techniques we use to gain insight within each domain. There is, however, a class of problems that requires an even stronger level of magnification going deeper down the stack to introspect CPU microarchitecture.

As companies accelerate digital transformation, cloud services such as AWS Lambda help companies to modernize their application architectures to quickly adapt to the needs of their customers while offloading the operational complexity to their cloud vendor. With the growing complexity of application architectures which can rely on tens of thousands of microservices, end-2-end observability is a requirement to optimize application performance and to deliver intelligent root-cause analysis.

So you want to build a REST API, but you don’t want to worry about the management burden when it comes to scaling it to meet the demand of your users. Or maybe you know your API will experience more burst usage than constant demand and you’d like to reduce your infrastructure costs. These are two great scenarios where a serverless architecture could benefit your API development.
