Manage APIs seamlessly across both cloud environments and on-premises systems: Alongside Azure, implement API gateways in conjunction with APIs hosted in various cloud platforms and local servers to enhance the flow of API traffic. Ensure that you meet security and compliance standards while benefiting from a cohesive management experience and comprehensive visibility over all internal and external APIs. Accelerate your operations with integrated API management: Modern enterprises are increasingly leveraging API architectures to foster growth. Simplify your processes within hybrid and multi-cloud settings by utilizing a centralized platform for overseeing all your APIs. Safeguard your resources effectively: Choose to selectively share data and services with employees, partners, and clients by enforcing authentication, authorization, and usage restrictions to maintain control over access. By doing so, you can ensure that your systems remain secure while still allowing for collaboration and efficient interaction.

In order to transform into enablers rather than obstacles, numerous IT departments are turning to integration platforms that empower users to independently manage their projects without depending on IT professionals. With challenges like budget cuts, a difficult journey to the cloud, and an ever-growing backlog of projects, IT faces unprecedented pressures. To shift from being seen as a barrier to a vital asset, many IT organizations are adopting solutions that allow for user-driven project completion instead of relying on IT specialists. The Axway Amplify Platform serves as a comprehensive enterprise integration solution designed to simplify integration complexities, uphold IT policies, and scale operations effectively. This platform allows teams to eliminate redundant, one-time integrations and instead concentrate on creating reusable integrations that can be utilized by a broader range of internal and external stakeholders. Additionally, by transitioning on-premises integration systems to the cloud or enhancing them with hybrid deployments, organizations can achieve significant cost efficiencies and enhanced scalability, offering even more advantages for modern business needs.

Lura is a high-performance API Gateway framework that is extendable, simple, and stateless, suitable for both cloud-native and on-premises environments. When working with REST APIs, particularly within microservices architectures, consumers often need to interact with backend services that were not originally designed with the user interface in mind. While this approach is beneficial, it can introduce significant complexity and strain on the UI consumers due to the varying sizes and structures of microservices responses. Lura effectively serves as a bridge between clients and source servers, simplifying interactions by delivering only the essential information required by the UI. It aggregates data from multiple sources into singular endpoints, enabling users to group, wrap, transform, and condense responses as needed. Furthermore, the framework offers robust support for a wide range of middlewares and plugins, which can enhance its functionality, including the integration of Oauth authentication and additional security measures. With Lura, developers can streamline their API interactions, significantly reducing overhead for front-end applications.
