Access Control
Edge Messaging Networks like PubNub provide Access Management security specifically designed for real-time messages, with fine-grain ability to enable access to each message channel for each user, even when there are billions of parallel channels.

Channel Groups
PubNub offers server-side channel control for the many use cases when you want to group thousands of sparse channels of messages together, allowing a user to subscribe to all of these channels simultaneously.

Globally Distributed Data Centers & Regional Storage
PubNub has 15 data centers distributed globally. More data availability and replication ensures that data can always be accessed quickly by users worldwide. Additionally, regional storage helps users to remain compliant with regulations.

Regional Failover and Autoscaling
Even with best efforts, data centers can sometimes fail. PubNub has the ability to failover to other geographic regions so your apps can continue to operate unhindered. Likewise, have a large event where a surge of messaging is coming in and the system would otherwise fail? PubNub helps here too by using auto-scaling, Kubernetes-based approach to ensure scale can instantly come online when customers need it, and scale down automatically to keep the customer costs low.
