In recent years, FPGAs have been deployed in data centres of major cloud service providers, such as Microsoft [1], Amazon [2], Alibaba [3], Tencent [4], Huawei [5], and Nimbix [6]. This marks the beginning of bringing FPGA computing to the masses, as being in the cloud, one can access an FPGA from anywhere. A wide range of applications are run in the cloud, including web servers and databases among many others. Memcached is a high-performance in-memory ob ject caching system, which acts as a caching layer between web servers and databases. It is used by many companies, including Flicker, Wikipedia, Wordpress, and Facebook [7, 8]. In this paper, we present a Memcached accelerator implemented on the AWS FPGA cloud (F1 instance). Compared to AWS ElastiCache, an AWS-managed CPU Memcached service, our Memcached accelerator provides up to 9 x better throughput and latency. A live demo of the Memcached accelerator running on F1 can be accessed on our website [9].
