By using Hasura, the e-commerce application benefits from streamlined data retrieval, reduced latency, and improved performance. Clients can retrieve all the necessary information from a single GraphQL endpoint, providing a seamless and efficient user experience.
Microservices architecture promotes modular and decoupled services, enabling organizations to efficiently scale and evolve their applications. Hasura plays a pivotal role in such architectures by acting as a federated GraphQL layer that orchestrates communication between microservices.
By integrating Hasura with your microservices infrastructure, you can seamlessly aggregate and compose data from different services, simplifying the development process and providing a unified API interface for clients.
Use Case: Social media analytics dashboard
- Hasura serves as a federation for multiple microservices, including user management, social media data retrieval, and analytics.
- Each microservice exposes its own GraphQL endpoint, and Hasura aggregates the data from these services.
- Hasura applies security policies, rate limiting, and caching to provide a unified and secure API for the analytics dashboard, improving performance and data consistency.
In this architecture, each microservice handles specific functionalities within the application. Hasura serves as the centralized entry point for API requests, routing traffic to the appropriate microservices.
Clients interact with Hasura's GraphQL API, which applies security, rate limiting, and caching policies to the requests. Hasura aggregates the responses from the microservices and presents a unified API to the client. This approach simplifies client-side integration and improves performance by reducing the number of network requests.
By using Hasura, organizations can enforce consistent security policies, manage API traffic efficiently, and provide a unified interface for clients. Additionally, Hasura's data composition capabilities allow clients to fetch and combine data from multiple microservices, providing a seamless and cohesive user experience.
Federated GraphQL with Hasura
Hasura's support for federated GraphQL enables organizations to build distributed systems that span across multiple data sources. By integrating Hasura into your API ecosystem, you can federate GraphQL schemas from various services and data providers.
This approach promotes data virtualization, allowing clients to interact with a unified GraphQL schema while abstracting the complexities of the underlying data sources.
Federation architecture should ideally be used when you have access to all your sources and high-performance joins across databases are required. With federated GraphQL and Hasura, you can achieve a seamless, consistent, and flexible data access layer.
Use Case: Travel booking platform
- Multiple GraphQL services, managed by different teams, handle various travel-related functionalities like flights, hotels, and car rentals.
- Hasura acts as the federation, combining these services into a single unified API.
- Hasura's data composition capabilities allow clients to fetch data across different services seamlessly, enabling a cohesive travel booking experience.
In this architecture, Hasura acts as the federation for multiple GraphQL services (GraphQL Service 1, GraphQL Service 2, GraphQL Service 3). Each GraphQL service is managed by different teams and handles specific functionalities.
Hasura, as the federation, combines these individual GraphQL services into a single, unified API. Clients interact with Hasura's GraphQL API, which orchestrates and delegates requests to the respective services. Hasura's data composition capabilities allow clients to seamlessly fetch data from across the federated services, providing a cohesive and integrated experience.
By leveraging Hasura as the federation, organizations can adopt a micro-frontend architecture, where different teams manage their own GraphQL services independently. Hasura handles the composition and aggregation of data, reducing the complexity of client-side integration and enabling a scalable and modular architecture.
Serverless architecture enables organizations to focus on writing business logic without the need to manage infrastructure. Hasura seamlessly integrates with serverless platforms, allowing you to leverage its powerful GraphQL capabilities within serverless functions.
By utilizing Hasura in serverless architecture, you can build dynamic APIs, handle real-time updates, and trigger event-driven workflows. This combination empowers developers to create scalable and cost-effective serverless applications with ease.
Use Case: Serverless chat application
- Hasura acts as the entry point for incoming chat messages and user actions.
- Based on the GraphQL queries or mutations, Hasura invokes serverless functions to handle specific functionalities.
- Hasura's dynamic invocation of serverless functions enables a scalable and event-driven API architecture for real-time communication in the chat application.
In this architecture, Hasura acts in a serverless environment. The system consists of multiple serverless functions, such as AWS Lambda or Azure Functions, which handle specific API endpoints or functionalities.
Clients interact with Hasura's GraphQL API, which acts as the entry point for API requests. Based on the GraphQL queries or mutations, Hasura dynamically invokes the corresponding serverless functions. This approach enables a scalable and event-driven API architecture.
Hasura's capabilities allow for centralized management of security, rate limiting, and caching policies. It simplifies the coordination and invocation of serverless functions, reducing the complexity of managing individual API endpoints.
