Kaskalis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, web servers are expected to serve thousands of client requests concurrently within stringent response time limits. In this paper, we evaluate experimentally and compare the performance as well as the resource utilization of popular web servers, which differ in their approach to handle concurrency. More specifically, Central Processing Unit (CPU)- and I/O intensive tests were conducted against the thread-based Apache and Go as well as the event-based Nginx and Node.js under increasing concurrent load. The tests involved concurrent users requesting a term of the Fibonacci sequence (the 10th, 20th, 30th) and the content of a table from the database. The results show that Go achieved the best performance in all benchmark tests. For example, Go reached two times higher throughput than Node.js and five times higher than Apache and Nginx in the 20th Fibonacci term test. In addition, Go had the smallest memory footprint and demonstrated the most efficient resource utilization, in terms of CPU usage. Instead, Node.js had by far the largest memory footprint, consuming up to 90% more memory than Nginx and Apache. Regarding the performance of Apache and Nginx, our findings indicate that Hypertext Preprocessor (PHP) becomes a bottleneck when the servers are requested to respond by performing CPU-intensive tasks under increasing concurrent load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apache" title="apache">apache</a>, <a href="https://publications.waset.org/abstracts/search?q=Go" title=" Go"> Go</a>, <a href="https://publications.waset.org/abstracts/search?q=Nginx" title=" Nginx"> Nginx</a>, <a href="https://publications.waset.org/abstracts/search?q=node.js" title=" node.js"> node.js</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20server%20benchmarking" title=" web server benchmarking"> web server benchmarking</a> </p> <a href="https://publications.waset.org/abstracts/162116/performance-comparison-of-thread-based-and-event-based-web-servers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162116.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Providing Reliability, Availability and Scalability Support for Quick Assist Technology Cryptography on the Cloud</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Songwu%20Shen">Songwu Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Garrett%20Drysdale"> Garrett Drysdale</a>, <a href="https://publications.waset.org/abstracts/search?q=Veerendranath%20Mannepalli"> Veerendranath Mannepalli</a>, <a href="https://publications.waset.org/abstracts/search?q=Qihua%20Dai"> Qihua Dai</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan%20Wang"> Yuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuli%20Chen"> Yuli Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Qian"> David Qian</a>, <a href="https://publications.waset.org/abstracts/search?q=Utkarsh%20Kakaiya"> Utkarsh Kakaiya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hardware accelerator has been a promising solution to reduce the cost of cloud data centers. This paper investigates the QoS enhancement of the acceleration of an important datacenter workload: the webserver (or proxy) that faces high computational consumption originated from secure sockets layer (SSL) or transport layer security (TLS) procession in the cloud environment. Our study reveals that for the accelerator maintenance cases鈥攏eed to upgrade driver/firmware or hardware reset due to hardware hang; we still can provide cryptography services by switching to software during maintenance phase and then switching back to accelerator after maintenance. The switching is seamless to server application such as Nginx that runs inside a VM on top of the server. To achieve this high availability goal, we propose a comprehensive fallback solution based on Intel庐 QuickAssist Technology (QAT). This approach introduces an architecture that involves the collaboration between physical function (PF) and virtual function (VF), and collaboration among VF, OpenSSL, and web application Nginx. The evaluation shows that our solution could provide high reliability, availability, and scalability (RAS) of hardware cryptography service in a 7x24x365 manner in the cloud environment. <p
