Apollo GraphOS Studio provides a free, native schema visualization tool for federated GraphQL APIs, allowing developers to explore their supergraph without running it locally or using separate tools. This improves introspection and understanding of the graph's structure, enabling easier navigation and sharing with others. The visualization also integrates metrics for performance analysis, highlighting fields by error rate, request rate, and P95 latency, helping identify areas that need debugging or optimization.

Platform engineering continues to be a prominent theme in the CNCF's KubeCon Europe 2024 conference, with a focus on API developer experience. Leading organizations like Netflix and Adobe are leveraging GraphQL and Apollo Federation to streamline API management and accelerate application delivery. Federated GraphQL serves as a powerful composition layer within an API platform, providing several benefits that align with the principles of cloud-native architecture. Its ability to enable flexible architecture, seamless developer experience, cost optimization, improved performance, along with a thriving open-source community, makes GraphQL a crucial layer of the API platform. The adoption of federated GraphQL is driven by its ability to improve developer velocity, security and standardization, making it an attractive solution for organizations seeking to optimize their API strategies.

Apollo GraphQL has joined the Cloud Native Computing Foundation (CNCF) as a Silver member, solidifying its commitment to innovation and promoting the importance of GraphQL in platform engineering. This strategic alliance is reinforced by Apollo GraphOS, its flagship product that enables backend teams to build an API composition layer called a 'supergraph'. A supergraph provides a scalable composition layer for backend teams, enabling client teams to use a declarative query language to fetch required data, reducing cognitive load on product engineering teams. The company recently launched a centralized change management workflow for schema proposals and will be showcasing its platform at the KubeCon + CloudNativeCon Europe 2024 conference.

The Netflix API evolution is a significant journey spanning 15 years and five generations of APIs, ultimately leading to the adoption of GraphQL. The company's Director of Product Platform Systems, Bruce Wang, discussed this transformation in an insightful fireside discussion with Matt DeBergalis, CTO at Apollo GraphQL. The journey involved breaking away from complex monolithic architectures, unifying APIs across diverse platforms, and empowering domain owners to manage their APIs independently. Netflix adopted the Apollo Federation specification to scale its GraphQL architecture, creating a unified supergraph that retained the integrated "Consumer Edge" API while decoupling domain teams. This approach empowered every team member to engage with concrete information, fostering data-centric discussions. Bruce highlighted four strategic lessons from Netflix's API evolution: tackling complex challenges first, balancing the needs of API clients and service owners, leaning into developer experience and API governance, and bridging silos by fostering inter-team conversations. These insights aim to support other teams in navigating their respective challenges and applying them across the organization.

To effectively monitor and analyze the performance of modern applications, it's crucial to customize events and reporting. The Apollo Router offers a toolkit for collecting and reporting data from an application's request lifecycle through telemetry events and instruments. Telemetry events signal significant occurrences in the request lifecycle, providing visibility into what happens during processing. Custom events can be configured to capture specific moments of interest, while standard events are available for logging requests, responses, and errors. Instruments allow for collecting metrics such as active requests, request body size, request duration, and response body size. Custom instruments can also be defined to collect specific metrics relevant to the application. By combining telemetry events and instruments, developers can gain valuable insights into their application's behavior, troubleshoot issues, and optimize performance.

The traditional approach to microservices in Kubernetes requires duplicating application logic into YAML config files, leading to information fragmentation and inconsistencies. However, using GraphQL and Apollo Federation can reduce the amount of required config, prevent duplication, and improve maintainability. With Apollo Federation, routing rules are declarative and avoid custom networking rules between services, preventing conflicting API routes and ensuring that routing rules always match the application code. This approach also simplifies Kubernetes config by removing application logic from YAML files, reducing the risk of shipping broken code and improving the reliability of microservices. Additionally, Apollo Federation decouples services, allowing them to evolve independently and explicitly documenting dependencies, which can be monitored and managed through a central router. By using GraphQL with Apollo Federation, teams can improve the maintainability and reliability of their microservices while saving time for development teams.
