The recent Microsoft Azure outage sent shockwaves through the tech world. Businesses scrambled to stay online, and developers faced lost productivity. Overall, it was a thorough reminder of the vulnerability of even the biggest cloud providers, particularly for businesses heavily invested in the Internet of Things (IoT).
Where thousands of connected devices depend on constant uptime, even a small service disruption in IoT platforms can have very critical consequences.
Although after a few hours, everything became normal, this normal makes many worried about the abnormality that has entered the world of internet technology.
There was a question in everyone’s mind: is this a sign to jump ship from Azure to AWS, or is there more to the story?
It is not easy for IoT enthusiasts to choose a better IoT platform than AWS and Azure, as both cloud giants provide excellent platforms that easily support complex IoT deployments.
The Outage and Its Impact on IoT
The Azure outage has impacted many services such as the IoT hub which is a core component of managing connected devices.
This resulted in data loss, communication breakdowns, and potential control issues for devices relying highly on real-time communication. This complete incident highlighted the importance of platform reliability, especially for mission-critical IoT applications.
Although an outage can happen at any time on any platform, Azure is considered to be a robust platform, and people in the tech world have a lot of confidence in it.
Here’s a table summarizing the reported impacts of the outage on different cloud services:
Cloud Service | Functionality Impacted | Potential Consequences for IoT |
Azure IoT Hub | Device Management, Message Delivery | Data Loss, Communication Disruption, Control Issues |
Azure Blob Storage | Data Storage Access | Disrupted Data Analytics, Application Downtime |
Azure Cosmos DB | Database Access | Device Data Loss, Service Disruption |
Root Causes of the Azure Outage
The recent Azure outage was primarily caused by a combination of factors:
Misconfigured Network Device
The starting point of the Azure outage was the network device that was configured incorrectly in the Central US area. Due to this misconfiguration, the network’s routing tables experienced sequential failures that diverted traffic and rendered the service unavailable to a large number of users.
Configuration Change in Backend Workloads
A specific configuration modification in Azure’s backend workloads caused connection issues between storage and compute resources. This outage impacted downstream services, particularly those that serve IoT applications, causing interruptions in businesses that rely on these resources.
Automated failover issues
The automated failover mechanisms, which were supposed to help solve such situations, did not work as expected. This failure caused the difficulties to spread, affecting more services and areas than the initial site of failure.

Which IoT Platform Handles Outages Better?
Both Azure and AWS have experienced outages, but their reactions have varied. When Azure had a recent outage, Microsoft responded quickly to resolve the issue and divert traffic from the impacted areas. They also worked with other cloud providers, like AWS and Google Cloud Platform, to share knowledge and identify solutions.
AWS, on the other hand, has received praise for providing clear and useful status updates during outages. The corporation also released its first public postmortem in two years following the us-east-1 outage, which was viewed as a promising move toward transparency.
Choosing Between Azure and AWS IoT Platform
When choosing between Azure and AWS IoT platforms, you must evaluate your specific requirements and expectations.
If you already use Microsoft products or services, AzS, and flexibility, AWS may be the way to go.
It is also critical to consider each provider’s track record for dependability and reaction to outages. While both Azure and AWS have suffered service interruptions, their responses to these issues may differ.
Finally, the ideal cloud choice for your organization will be determined by your specific needs and goals. Before making a selection, it is essential to go through the table we have provided above.
Conclusion
The recent outages experienced by Azure have highlighted the importance of choosing a reliable and responsive IoT platform. While both Azure and AWS platforms offer a range of services and advantages, the decision ultimately comes down to your specific needs and requirements.
When comparing Azure vs AWS, consider factors such as integration, variety, flexibility, market share, and each provider’s approach to handling outages.
By carefully considering these issues, you can make the right selection and guarantee that you have a safe and dependable cloud solution.
