Businesses are becoming increasingly global and need to be able to support their customers in these new markets. To minimize the impact of network latency, they can choose to have their content served from regional data centers supported by their hosting provider. As user traffic increases, the cost of supporting these new markets increase due to high bandwidth and data egress from these sites. While solutions such as content delivery networks (CDNs) have helped businesses increase their global reach more cost-effectively, many of the established providers have built monolithic legacy infrastructures that are difficult to manage and are not sufficiently responsive to meet the demands of aggressively agile workflows.
Cloudflare has built an expansive network of global data centers that cache static content closer to users. Caching frequently accessed files on Cloudflare's network reduces the distance content needs to travel to get to the user and minimizes the impact of high latency on web page load times. Cloudflare's network is API first, allowing customers to easily automate workflows with highly granular controls of how content is cached and purged. Caching content on Cloudflare's network lowers the need to source content from hosted servers or origins, and reduces bandwidth utilization costs from the origin. Customers that host their websites with any of Cloudflare’s partners will receive data transit discounts for any requests from their origins to Cloudflare's network.
