Cloud Availability: The Biggest Trap of 2021
Author Carey Nieuwhof hooked me with a blog topic of the biggest trap for 2021. While not directly speaking to HA, the topic alone made me reflect on some of the trends of 2020. Cloud innovations are numerous and begin at the most fundamental levels of the infrastructure. Not to mention advances in AI, machine learning, compute capacity and algorithms, memory management and sharing, and a battery of others. All of these advances add up to making the current generation cloud the most robust, reliable and available data center. These centers, optimized with redundant power, cooling, a legion of IoT devices for monitoring and alerting, redundant networking, high speed interconnects, massive servers, storage, and disks are impressive– and quite possibly the biggest trap that may be looming in 2021.
The biggest trap of 2021 will be believing that cloud availability alone is the same as or enough for higher availability. This is a complex trap to dissect. The list of named advances that make up the backbone of many data centers is indeed vast and impressive, and it is only a fraction of the technological innovations that exist driving the cloud. So, what makes this massively redundant, high capacity, and AI driven infrastructure a trap? Namely, that hardware and infrastructure availability still leave your enterprise at risk.
