Ensuring True High Availability in an Online Retail Environment

Unlike most of the world, an online retail business never sleeps, which means that the systems powering an online retailer’s critical operations can never sleep either. If the organization wants to sell products and meet the needs of customers on a 24-by-7 basis, it’s going to need a way to ensure that its infrastructure remains not only online but also operational and accessible.

That “operational and accessible” part is often overlooked. Cloud service providers can offer high availability (HA) configurations with a service level agreement (SLA), guaranteeing that at least one node in a multi-node cluster will be online 99.99% of the time. However, that SLA doesn’t ensure that the applications or data powering an online business will be operational or accessible.
