AiScaler

aiScaler Ltd is a software company founded in 2008 that develops application delivery controllers for dynamic websites.aiScaler Ltd 是一家成立于 2008 年的软件公司，开发面向动态网站的应用交付控制器。

Its software caches, compresses and routes HTTP traffic so that origin servers handle fewer requests during traffic spikes.其软件对 HTTP 流量进行缓存、压缩与路由，使源站在流量高峰期间处理更少的请求。

It can run as a virtual appliance in public clouds such as Amazon Web Services or Microsoft Azure, in private virtual environments, or on dedicated hardware sold with Dell.它既可以作为虚拟设备运行在 Amazon Web Services 或 Microsoft Azure 等公有云与私有虚拟环境中，也可以运行在戴尔销售的专业硬件上。

History

• The technology began in 1994 as a project called Jxel, short for Java Accelerator, inside the web development company WBS.该技术最初于 1994 年作为名为 Jxel 的项目出现，Jxel 是 Java Accelerator 的缩写，项目隶属于网页开发公司 WBS。
• Jxel was written in Java and designed to run on a Java virtual machine that shared the same computer system as the HTTP server.Jxel 以 Java 编写，设计为运行在与 HTTP 服务器共用同一计算机系统的 Java 虚拟机上。
• In July 2008 aiScaler Ltd acquired all technology of WBS for 3.8 million US dollars, according to the company's published history.根据公司公布的历史，aiScaler Ltd 于 2008 年 7 月以 380 万美元收购了 WBS 的全部技术。
• The product was rewritten in 2009 in the C language and moved onto its own dedicated server rather than sharing the HTTP server's machine.该产品于 2009 年用 C 语言重写，并迁移到独立服务器上，而不再与 HTTP 服务器共用一台机器。
• The rewrite ran only on Linux and took advantage of epoll, the operating system's event notification interface for large numbers of connections.重写后的软件只在 Linux 上运行，并利用 Linux 的事件通知接口（epoll）处理大量连接。
• Abandoning the Java virtual machine removed the need to keep a JVM in step with the HTTP server and let the accelerator run on a stripped-down Linux host.放弃 Java 虚拟机后，加速器不再需要让 JVM 与 HTTP 服务器保持同步，并可运行在精简的 Linux 主机上。
• The epoll-based design was intended to hold many idle connections open without dedicating a thread to each one, a common requirement for public websites.基于该接口的设计旨在保持大量空闲连接而不必为每个连接分配线程，这是公共网站的常见需求。
• Until 2013 the company was known as aiCache and sold a product called aiScaler.在 2013 年之前，公司名称为 aiCache，销售的产品则叫作 aiScaler。
• It then adopted the name of its main product for the company itself and phased out the aiCache brand.此后公司采用主要产品的名称作为公司名，并逐步停用 aiCache 品牌。
• The company has remained privately held and has not disclosed outside funding rounds or revenue totals.公司一直保持私人持股，未披露外部融资轮次或收入总额。
• By 2020 its website advertised on-premise, Amazon and Azure pricing together with a 30-day free trial and free installation support.到 2020 年，其网站已提供本地部署、Amazon 与 Azure 的定价方案，以及 30 天免费试用与免费安装支持。
• A Wayback Machine snapshot from 2025 shows the site still marketing aiScaler alongside aiCDN, aiVideo and cloud deployment options.2025 年的 Wayback Machine 快照显示，该网站仍在推广 aiScaler，并同时宣传 aiCDN、aiVideo 与云部署选项。

• The software can be deployed as a virtual appliance in public clouds, including Amazon Web Services, Microsoft Azure and CenturyLink environments.该软件可作为虚拟设备部署在公有云中，包括 Amazon Web Services、Microsoft Azure 与 CenturyLink 环境。
• Because it proxies traffic at the edge, aiScaler can sit in front of an origin and take over functions normally handled by a content delivery network.由于在边缘代理流量，aiScaler 可以部署在源站之前，接管通常由内容分发网络承担的功能。
• The company says the product can reduce origin load by more than 80 percent, although the figure depends on cacheable content and traffic patterns.公司表示该产品可将源站负载降低 80% 以上，不过这一数字取决于可缓存内容与流量模式。
• Its reporting tools expose more than 200 real-time metrics so operators can alert on and diagnose application problems before users notice them.其报表工具提供 200 多项实时指标，使运营方能够在用户察觉之前对应用问题发出告警并进行诊断。
• aiScaler also performs HTTPS offload and manages the user session layer, freeing origin servers from encryption and session bookkeeping work.aiScaler 还执行 HTTPS 卸载并管理用户会话层，使源站从加密与会话记录工作中解脱出来。
• Mobile redirection and content rewriting let a site present different markup to phones and tablets without changing the origin application.移动重定向与内容重写使网站能够向手机与平板呈现不同的标记，而无需修改源站应用。
• The product uses a right-threaded, non-blocking and multiplexed input-output design in which a fixed number of workers process requests regardless of how many clients connect.该产品采用右线程化、非阻塞与多路复用的输入输出设计，无论连接多少客户端，都由固定数量的工作线程处理请求。

• Pricing is published separately for on-premise, Amazon and Azure deployments, and a free trial is available before a purchase.本地部署、Amazon 与 Azure 部署分别公布价格，购买前还可使用免费试用。
• Cached responses are stored close to the edge, so repeat visitors receive content without a round trip to the origin database or application server.缓存响应存放在靠近边缘的位置，因此回访用户无需经过源站数据库或应用服务器即可获得内容。
• Compression of text responses reduces the number of bytes sent over the network, complementing caching for pages that cannot be reused.对文本响应进行压缩可减少网络传输的字节数，对无法复用的页面形成补充。
• The load balancer can spread requests across several origin servers, allowing a site to keep serving traffic when one server is unavailable.负载均衡器可将请求分散到多台源站服务器，使网站在某台服务器不可用时仍能继续服务。
• TLS termination at the edge means the origin receives plain HTTP traffic while the customer's certificate is presented to the browser by the accelerator.在边缘终止 TLS 意味着源站接收明文 HTTP 流量，而加速器向浏览器出示客户证书。
