This paper explores the design and implementation of a cloud-based burst buffer system aimed at accelerating I/O performance for data-intensive applications in cloud environments. By leveraging the high throughput between compute nodes, the system buffers application data, effectively mitigating the I/O bottlenecks typical in shared cloud storage. A prototype implementation on Amazon EC2/S3 demonstrated significant performance enhancements, achieving up to 2.9 times improvement in execution time for real-world applications and reducing monetary costs by 50%. The proposed system not only addresses the critical issue of low I/O throughput but also offers scalable and cost-effective solutions for high-performance computing in the cloud.

Web APIs have become the backbone of modern applications, enabling everything from social media integrations to enterprise data exchanges. With this growing reliance on APIs, attackers constantly seek to exploit vulnerabilities and gain unauthorized access. This paper examines the essential role of authentication in securing web APIs. It discusses foundational security principles, popular authentication methods (such as OAuth 2.0, OpenID Connect, and JWT-based workflows), and the common pitfalls that lead to breaches. We also explore best practices and emerging trends like zero trust architecture and decentralized identity systems. Our goal is to provide readers with a comprehensive understanding of web API authentication, enabling them to implement more robust security measures and anticipate future developments.
