Shulou(Shulou.com)11/24 Report--

CTOnews.com April 25, JD.com Cloud officially released the first CVM based on ARM architecture, which is equipped with the latest Ampere Altra Max cloud native processor. Thanks to the single-core single-threaded design of ARM processor, its multi-core concurrency performance is better than that of X86 server, with a performance improvement of more than 60% and a price reduction of 20%.

Jingdong Cloud ARM CVM supports more than 20 different CVM instance specifications in 3 categories, covering general computing, computing optimization, memory optimization and other application scenarios (CTOnews.com Note: officially, the maximum specification can reach 64 cores 512GB). Customers can flexibly choose the required specifications according to their own business to meet the business needs of various scenarios.

Before the official external commercial use, JD.com Cloud ARM CVM has been tested in JD.com 's internal scenarios. It has experienced high concurrency and high load scenarios such as JD.com and JD.com, and has undertaken core and complex physical applications such as JD.com retail and logistics, and its reliability has been verified.

Jingdong Cloud ARM CVM is equipped with Ampere Altra Max cloud native processor, which is suitable for businesses with high performance requirements and high workload density. The related features are as follows:

The processor installed in this launch example has a higher main frequency, up to 3.0GHz, which can achieve ultra-high computing speed and leading single-core computing performance; constant maximum main frequency per core, stable performance.

In the single-core and single-threaded design, each vCPU of the CVM enjoys a physical core, with little performance interference between cores, which ensures that the performance improvement of the CVM is almost linear with the increase in the number of cores.

ARM architecture processors provide low-power computing while taking into account reliable performance, reducing power consumption by nearly 30%, more energy saving and lower price.

Take NGINX, the most common front-end component in Web application software stack, as an example, due to the design of ARM processor single-threaded core, larger exclusive low-latency L1 and L2 cache, and stable performance brought by constant maximum frequency, it has excellent performance in high concurrency Web application scenarios.

After testing, under the same 8-core 32G CVM configuration, the NGINX performance of Jingdong Cloud ARM CVM is improved by 60%. On the premise of high performance, it also achieves a low price. Taking the above Web application as an example, the business cost reduction can be as high as 50%.

Jingdong Cloud ARM CVM is suitable for workloads and application scenarios built with open source software stack and based on cloud native technology:

Web Service (NGINX)

Essential coding load for video services (H.264 / H.265)

Open source database (MySQL,PostgreSQL,MongoDB,Cassandra, etc.)

Memory caching system (Redis) which requires high query and processing speed

Big data system (Hadoop,Spark)

AI reasoning (TensorFlow, PyTorch, ONNX), etc.

With the rich ecology of ARM architecture, Linux commercial distributions, including kernels and toolkits, virtualization frameworks represented by KVM, Docker and K8S have natively supported ARM architecture, which can be downloaded and deployed directly in ARM CVM. Currently, Jingdong Cloud has provided a variety of official Linux images such as CentOS, Ubuntu, OpenEuler and so on.
