Tata Communications, a company of Indian multinational Tata Group, offers a CDN service with 400 points-of-presence (PoPs) on five continents, in 21 locations. Tata owns and operates an impressive network infrastructure, with their sub-terrestrial and sub-sea network spanning 700,000 kilometers - more than 17 times around the world. According to the company, 24% of the planet’s internet routes are on their network, which grants improved performance and flexibility.
In 2011, Tata Communications acquired BitGravity - a US-based CDN provider founded in 2006. BitGravity. The companies had been in a strategic alliance leading up to the acquisition, and the move was a logical next step for Tata Communications to improve its global CDN offering. Remnants of BitGravity can still be found, such as the Tata Communications CDN support portal.
Tata Communications offers a wide range of CDN features such as live streaming and video-on-demand (VOD), an out-of-the-box online video platform, site acceleration and software delivery. They also provide DDoS and security services, hosting, colocation and transit.
Incapsula Inc. provides a variety of CDN services, from the network itself to security, load balancing, failover solutions and DDoS protection. The company spun out from data security company Imperva in 2009. Incapsula launched Botopedia in 2012, a directory that includes community-sourced information about bots.
At the core of Incapsula’s feature offering lies the content delivery network and a variety of security features such as web application firewall (WAF) and DDoS mitigation.
Incapsula composes comparison tables of its own, which can be viewed on their website - providers they compare themselves to are Akamai and CloudFlare. In the comparison tables they dive deeper into the various security features within the content delivery ecosystem.
Like most other CDN providers, Incapsula integrates well with a variety of Content Management Systems (CMS) and also offers a downloadable extension on their website for Joomla. The extension improves security and performance for Joomla. Other security solutions for third parties offered by Incapsula are targeted at clients hosting with Rackspace, Microsoft Azure and Amazon AWS. All three of these also offer their own CDN solution.
