A centralized developer portal like Backstage acts as a "single pane of glass" for engineering teams. It unifies infrastructure tooling, service catalogs, software templates, and technical documentation into one consistent user interface. This centralization is critical for efficient cloud-native adoption as it reduces cognitive load on developers, who no longer need to hunt for disparate resources. By providing a single, discoverable access point for all platform services and knowledge, it streamlines onboarding, accelerates development workflows, and ensures that teams can easily find and use the tools and standards provided by the platform engineering team.

B. A developer portal's purpose is to support the organization's specific platform and technologies, not to provide general education on unrelated topics.

C. While knowledge sharing is a benefit, the portal is designed for official organizational software components and services, not informal sharing of personal projects.

D. The goal of a developer portal is to democratize access and empower all developers, not to create bottlenecks by restricting tools to senior staff.

1. Backstage Official Documentation

"What is Backstage?": The documentation states

"Powered by a centralized software catalog

Backstage restores order to your microservices and infrastructure... It's a single

consistent UI that sits on top of your whole infrastructure and developer tooling." This directly supports the concept of a single access point. (Source: backstage.io

"Introduction" section).

2. Backstage Official Documentation

"Core Features - Software Catalog": The Software Catalog is described as the core feature that allows you to "manage all your software... in one place." This reinforces the idea of a centralized system for all services. (Source: backstage.io/docs/features/software-catalog/

"Overview" section).

3. Backstage Official Documentation

"Core Features - TechDocs": This feature is described as a "docs-like-code solution for all your technical documentation

" which is integrated directly into the portal

centralizing documentation alongside the services it describes. (Source: backstage.io/docs/features/techdocs/

"Introduction" section).

4. Cloud Native Computing Foundation (CNCF)

"CNCF Project Page for Backstage": The CNCF

which hosts the Backstage project

describes it as an "open platform for building developer portals

" highlighting its role in creating a unified experience for cloud-native development. (Source: cncf.io/projects/backstage/

"Project Description" paragraph).
