Rescuing Cloud Infrastructure & Driving Long-Term Security with AWS Well-Architected Review

Just a week into a new partnership, a digital lending company contacted NeenOpal on New Year’s Eve due to a critical infrastructure outage. Their production systems had been down for over two business days, disrupting operations during a peak traffic period. NeenOpal’s DevOps team promptly intervened, restoring services within hours. This immediate resolution was followed by a comprehensive AWS Well-Architected Framework Review (WAFR) to identify underlying reliability issues and deliver a clear roadmap for building a scalable and resilient cloud infrastructure.
