A common question is asked for anyone wanting a highly available cloud offering is should we use multiple cloud providers? So what are the drawbacks and most importantly, should you use a multi-cloud offering? This is common between AWS and GCP.
What is multi-cloud?
Multi-cloud is running the same workload (WordPress cluster for instance) across multiple cloud providers in a completely agnostic way. Multi-cloud is a great option when downtime must be kept at a minimum. Where a fault within a cloud or multi-region service (Multi-AZ) can not cause a material outage to your website.
When should multi-cloud be avoided?
Multi-Cloud can come with major side effects such as more downtime; usually in the form of technical debt with platforms that were not initially designed to scale this way. WordPress websites typically can scale in this manner with the proper platform
What are the cost considerations?
You may expect Multi-cloud platforms to be 2x in price, however, this would be a misconception. Multi-cloud typically costs 3 to 4 times more. Not only is there 2x the compute required but the software development required to keep these systems working. Maintenance requirements are significantly more than traditional single cloud providers.
Why Multi-cloud vs Multi-AZ with a single cloud provider?
This is a really good question; and one that needs to be carefully considered. A full cloud provider outage in multiple regions is extremely rare. With a properly configured Multi-AZ cluster, you’re almost guaranteed a five 9 uptime service level with a significantly reduced cost. You should evaluate the possible benefits of Multi-Cloud in your business vs the additional cost to make it happen.
