Always-on – key architectural elements

There are defining features of cloud-native architectures that allow for an always-on, technically resilient architecture. This is not an all or nothing proposition, and many deployments will feature a mix of the features we are going to be talking about. Do not overwhelm yourself or your architects by believing all these features can be incorporated into a deployment overnight. An iterative, evolutionary approach is needed to adopt the key design elements we will be discussing. As Werner Vogels (CTO Amazon) says, "Everything always fails." If we plan for inevitable failure, we can design systems to avoid it.

Network redundancy

Connectivity into the cloud and across all your environments should be provided in a highly available, redundant manner. There are two main implications for this in a cloud-native world. The first implication is the physical connectivity from an on-premise environment or customer into the cloud. All hypercloud providers provide...
