In Netflix the microservice architecture is widely adopted and each microservice typically handles only one type of data. No need to acquire locks on tables, which is essential to ensure that the write traffic on the database is never blocked by our service. The architecture of the framework is illustrated in the following Chart.

This capability is essential when performance tuning since query events include discrete CPU and IO metrics as well as runtime parameters, which are key for troubleshooting query performance problems such as parameter sniffing. Although this can be somewhat helpful, it is not the same. For some reason this thing will not go away!

In serverless architecture, when applications are developed, they are typically composed of many different services. Other benefits to serverless architecture include the following: Cost. There is plenty to like about moving to a serverless architecture, but there can be some disadvantages compared to the traditional, monolithic model.
