使用CDN保護你的網上店面

今日我們正生活在一個和網絡密不可分的世代 ,因此大小商戶都會建立網站,為客戶帶來方便,可是網路世界無奇不有,即使網主沒有仇家也沒挑釁過誰、網站也沒有透露政治立場,只要你的網站有商業價值,或存有保安漏洞,就有機會被黑客攻擊,當中以癱瘓網站伺服器流量的手法最常見。有見及此,商戶會使用CDN (Content Delivery Network,內容傳遞網路)服務,將網站內容散佈在暫存在不同的CDN伺服器中,即使網站被攻擊癱瘓了,會自動切換至另一台主機頂替,就像網站的影分身一樣,使你網上的店面能保持營業狀態。CDN這種雲端服務的價格也並非小企業無法承擔,好像CloudFlare就以出色的免費基本服務而聞名。
