Microsoft’s cloud computing platform Microsoft Azure includes a CDN service in their offering. The platform was released in 2010, initially named Windows Azure and renamed to Microsoft Azure in 2014.
Azure is an Infrastructure-as-a-Service (IaaS) solution, and next to a CDN they offer storage solutions, data management, compute and networking. Their IaaS solution is similar to Amazon Web Services (AWS) and Google Compute Engine (GCE). Just like Google, Azure offers free credit to first-time users of the platform to help them get started.
The Azure CDN service uses the networks of Akamai and Edgecast, though it is fully integrated with the cloud platform and offered under the Azure brand. Because the CDN service is offered as a part of the larger Azure IaaS ecosystem, it is easy-to-use for businesses who already use the platform. Other CDNs can be used in combination with Azure products as well, for example with their storage solution.
Instart Logic is a CDN provider founded in 2010, and is headquartered in Palo Alto, California. The company is known for its $100 million contract buyout campaign targeted at Akamai customers.
Customers in the Instart Logic portfolio include, or have included: Quora, Washington Post, and Kongregate. At the time of writing, the listings on the website seem out-of-date, as GameStop, Staples, Shutterstock, Yum!, L’Oreal and Pizza Hut no (longer) look to be customers of Instart Logic. At least not for static file delivery.
Through a partnership with ChinaCache, Instart Logic offers coverage of mainland China with points of presence (PoPs) in roughly 140 cities.
Instart Logic supports SPDY.
