It gives us immense pleasure to extend a warm welcome to you for the 2024 edition of the Workshop on Hot Topics in Cloud Computing Performance - HotCloudPerf 2024. Cloud computing represents one of the most significant transformations in the realm of IT infrastructure and usage. The adoption of global services within public clouds is on the rise, and the immensely lucrative global cloud market already sustains over 1 million IT-related jobs. However, optimizing the performance and efficiency of the IT services provided by both public and private clouds remains a considerable challenge. Emerging architectures, techniques, and real-world systems entail interactions with the computing continuum, serverless operation, everything as a service, complex workflows, auto-scaling and -tiering, etc. The extent to which traditional performance engineering, software engineering, and system design and analysis tools can contribute to understanding and engineering these emerging technologies is uncertain. The community requires practical tools and robust methodologies to address the hot topics in cloud computing performance effectively.
