I'm curious about cloud infrastructure practices. It seems like many companies are mainly using US-East-1 as their primary region without a backup, even after the recent outage that only impacted this area. Why wouldn't they opt for US-East-2 or other regions for added redundancy? I worked in application support for the NYSE two decades ago, and they had a primary data center with a hot backup that would kick in immediately if the main site went down. Is there a reason companies don't implement similar setups in cloud environments?

AWS actually provides high availability within US-East-1 through multiple availability zones. So for most cases, companies rely on that setup to handle outages, which is often enough for them. They might not want to add the extra cost and complexity of a whole new region when they already have protections in place.
You’ve nailed it. Many businesses think their existing setup will protect them during an outage, not realizing the full extent of possible scenarios.
You’re right; it is technically possible to have backups in other regions, but most setups are not prepared for regional outages. It seems like many organizations accept the risk, probably due to costs or lack of foresight. The complexity of managing multiple regions, like added latency and cost of data transfer, makes it tough.
That’s a fair point. Building a robust multi-region strategy requires a lot of investment, which many companies are hesitant to make until they face a crisis.
And then there’s the challenge of data governance and the legal issues that arise when moving data between regions. It’s not always straightforward.
You’d think redundancy would be a standard practice these days! But many industries prefer to minimize costs and only invest in DR setups after experiencing an outage, leading to gaps in preparedness. Some companies, like Netflix, actually use chaos engineering to test their systems constantly to ensure reliability.
That’s so true! Most companies don't test their DR setups regularly, which can leave them vulnerable when a real crisis hits.
And of course, legacy applications can complicate things, as they're often not designed for high availability across different regions.
Actually, there are a lot of factors at play here. The recent outage affected services that were dependent on US-East-1, but many companies using other regions weren’t impacted. Some services like DNS and IAM are shared globally, which can create issues even if your services are in a different region. AWS usually has great post-incident write-ups if you want to understand more about specific outages.
Exactly! Even if you operate outside US-East-1, if your services rely on global resources like IAM, you could still be in trouble. It’s not just about where your primary data center is located.
Also, some vendors were affected despite using other regions due to dependencies on shared services. Some companies managed to quickly switch to another region and keep things running.
Exactly! But I think some companies don’t leverage that properly and end up underestimating the risk of a full regional outage.
