Does It Survive the Provider?

About this interactive

A big cloud provider gives you all the redundancy in the world inside it: regions, zones, managed services. It all still sits on that provider's backbone. The lesson's SaaS company ran in AWS's Oregon region with failover to Virginia. When Virginia had a six-hour problem, services that leaned on S3 there went wrong too, because everything was part of the same provider. Provider redundancy spreads the service across more than one provider: AWS, Microsoft Azure or Google Cloud as infrastructure as a service; colocation, where you rent space and run your own equipment; or on-premises equipment you control yourself. The lesson's example runs in colocation, fails over to a cloud provider, and keeps on-premises servers as the last fallback.

What you'll learn

Decide whether a hosting design survives an outage across one cloud provider's whole platform, by whether its failover lies with another provider, in colocation or on premises

Key terms

Cloud Provider Redundancy: A strategy that distributes services across multiple cloud providers to prevent a single provider's outage from causing a complete service disruption.
Colocation: A data center model in which an organization rents physical space, power, cooling, and network connectivity from a third-party facility while retaining ownership of its own servers and equipment.
On-Premises: An infrastructure deployment model in which hardware and software are hosted locally within an organization's own facilities rather than in a cloud provider's data center. On-premises deployments give organizations full control over their security posture.
Infrastructure as a Service: A cloud service model that provides virtualized computing infrastructure over the internet.
