Amazon Virtual Private Cloud (VPC) is a commercial cloud computing service that enables users to create a logically isolated section within the AWS Cloud. Users can deploy AWS resources in a self-defined virtual network within this isolated section. In essence, it enables customers to build resources within a private, separated area of the AWS cloud, such as databases, Elastic Compute Cloud (EC2) instances, and other AWS services. AWS offers VPC to enterprises as a way to improve cloud security.

Microservices are now the architecture of choice for many developers when crafting cloud-native applications. A microservices application is a collection of loosely coupled services that communicate with each other, enhancing collaboration, maintainability, scalability, and deployment. There are several options for enabling this communication between microservices. When it comes to Python, gRPC and REST are two extremely popular directions to go.

A DNS zone transfer is the process of transferring DNS records and zone files data from the primary server to the secondary server. This updates the secondary server with the current records and zone files so that it can act as a backup during failover scenarios. Zone transfer extends network services when the primary server fails by copying the primary server’s files to the secondary server.

Nodejs is a popular Javascript runtime environment that executes Javascript code outside of a web browser. Express is the most popular web frameworks that sits on top of Nodejs and adds functionalities like middleware, routing, etc. to Nodejs. You can monitor your express application using OpenTelemetry and a tracing backend of your choice.

OpenTelemetry can be used to trace Rust applications for performance issues and bugs. OpenTelemetry is an open-source project under the Cloud Native Computing Foundation (CNCF) that aims to standardize the generation and collection of telemetry data. Telemetry data includes logs, metrics, and traces. Rust is a multi-paradigm, general-purpose programming language designed for performance and safety, especially safe concurrency.
