The 2021 Azure outage highlighted the significant risks associated with reliance on major cloud service providers like Microsoft, Amazon, and Google, collectively known as the Big 3, which offer indispensable services for modern enterprises. The Azure outage, triggered by a DNS code defect, temporarily disrupted services relied upon by over 280,000 companies, including critical functions like data security and system monitoring, exposing vulnerabilities inherent in vendor lock-in and single-supplier dependency. This incident, along with similar outages from AWS and GCP, underscores the necessity for businesses to develop contingency plans and consider hybrid cloud solutions or third-party platforms like Coralogix, which integrate services from multiple vendors to enhance resilience, system visibility, and security, thereby mitigating the impact of such outages on business continuity.
