In April 2021, Auth0, a major identity provider, experienced a significant outage, highlighting the vulnerability of relying on SaaS solutions. This incident is part of a broader trend where major cloud and SaaS providers face outages, prompting organizations to consider self-hosting as a potential solution for improved reliability. While self-hosting offers benefits like compliance, data ownership, and cost control, it also entails challenges such as operational demands and hidden costs. The decision between SaaS and self-hosting involves weighing factors like compliance requirements, data control, performance needs, and cost implications, which can vary based on an organization's size and industry. Although self-hosting allows for greater control and customization, it requires significant resources and expertise that not all organizations possess. As companies navigate these choices, they must also be aware of the legal implications and the potential for evolving deployment strategies, ensuring flexibility to switch between models if necessary.
