KeyCDN is CDN provider from Switzerland with 24 points-of-presence (PoPs) worldwide, and 8 more PoPs planned. The CDN service is part of proinity GmbH, a Swiss IT services company that’s also behind image optimiser Optimus.
KeyCDN was founded in 2012 by Jonas Krummenacher and Sven Baumgartner. Their network is non-federated; the entire infrastructure is owned by KeyCDN.
The provider’s feature offering includes two-factor authentication, DDOS protection, origin shield, real-time reporting and more than 24 CMS integrations such as with WordPress, Magento and Joomla.
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.
