NFINIT’S POV on Recent Public Cloud Outages
Last week’s major AWS outage, along with October’s Azure outage, exposed vulnerabilities of public cloud – especially when it dominates an organization’s cloud environment. Depending on a single cloud environment for compute, critical applications, storage, and backup is the proverbial “putting all your eggs in one basket.” When the basket falls apart, everything breaks.
While using multiple Availablity Zones and Regions within a public cloud offers some level of redundancy and failover capabilities, it often doesn’t provide your organization total protection from an outage. Some of the critical core services that public clouds provide are centralized within a particular region and an outage there can have cascading effects on services running in other regions.
The best strategy is a multi-cloud approach. It spreads risk while increasing the potential for maintaining full operations when there’s an outage or incident. Public cloud is often a significant part of this approach. Notice that I put emphasis on “part”.
Should there be an outage, like what just happened with AWS, workloads can failover to a different cloud environment. There would also be multiple backups to restore data and function quickly and cost effectively.
In news coverage of the AWS event Naveen Chhabra, a Senior Analyst with Forrester, stated “Crafting a complex online service that can be easily shifted from one provider to another in case of emergency is far from simple.” Building, managing, and maintaining a multi-cloud infrastructure requires expertise with multiple cloud platforms.
The article goes on to report how customers with a single-cloud strategy are caught off guard when they want to extract data, either to restore data or to move to a competitor. Called “egress fees”, these charges can be significant.
A resilient multi-cloud strategy includes a cloud storage option that eliminates egress and transaction fees for certain applications or data types. We often recommend NFINIT Object Storage for cloud backup that doesn’t cost the client when they pull their data out.
Outages are going to happen. It happening to dominant players shows that no single cloud environment is infallible and that a multi-cloud strategy is essential.
