Crisp

Crisp 使用 Cloudflare 的負載平衡來改善其客戶關係應用程式的整體性能。

Crisp is a SaaS based customer relationship application, providing customers with features such as a chat box, email replies, and an operator dashboard to quickly reply to customer queries. Crisp targets the unpenetrated markets of Eastern Europe, Asia, and the Middle East, where a customer relationship solution doesn’t exist or customers are in need of replacing outdated and expensive legacy technology.

Crisp’s Challenge: Ensure Global Performance While Maintaining Local Infrastructure

隨著 Crisp 的發展,他們希望通過維護其歐洲基礎設施來最小化額外開銷,同時仍為客戶提供高性能平台。 Crisp 首席執行官 ValérianSaliou 解釋說:「最初,我們在亞洲存在很多延遲問題,因為聊天應用程式的動態內容在使用者和歐洲伺服器之間來回往返需要花費時間。 從最開始,我們就一直在使用 Cloudflare 的 CDN,這項服務立即將靜態資產的交付時間提高了幾秒鐘,但是我們仍在尋找一種解決方案來優化動態內容的交付,並且需要使我們能夠維持歐洲標準基礎設施。」

Crisp’s Solution: A Cloud-Based, Global Load Balancer

When Crisp saw Cloudflare’s Load Balancing Early Access offering, they opted into the program to see if they could leverage it to help with the latency they were seeing with dynamic content. Cloudflare’s Global Load Balancing routes Crisp’s customers to the origin server closest to them, which not only shortens the distance content needs to travel, but also allows for cryptographic termination closer to the end user—ensuring minimal latency for the end user. The results were better than Crisp could’ve hoped— “When we rolled out Cloudflare Load Balancing,” Saliou explained “to route traffic across our atlas of websocket servers (tunneled into our core infrastructure through a VPN), we immediately got messages from customers in Asia and Oceania thanking us for the improvement.” With Load Balancing, Crisp saw latency times of their dynamic content drop an additional 2-3 seconds . Plus, with Health Checks and Failover built into Cloudflare Load Balancing, Crisp’s customers enjoy continual unfettered performance through Crisp’s ability to monitor the health of their websocket servers and automatically shift traffic to healthy servers when a server is experiencing poor performance.

當 Crisp 向公眾發佈 API 時,還享受到了 Cloudflare 的頁面規則和 DDoS 保護的好處。 「我們預設使用『緩存所有內容』來説明節省頻寬,然後使用『頁面規則』為我們的 API 指定例外,並為某些服務指定不同的 TTL。」Saliou 解釋說。 此外,Crisp 借助 Cloudflare 的 DDoS 保護對 API 提供保護。 Saliou 繼續說道:「到目前為止,我們已經阻止了 2 次攻擊,這些攻擊試圖使我們的 API 離線,在兩次情況下我們的服務都沒有中斷。」

Saliou 總結說:「成本是我們的重要決策因素,而即使我們不考慮成本,Cloudflare 在服務、入門和易用性方面仍優於競爭對手。」
