- Software used to be simple with databases, user interfaces, and glue code running on web servers.
- Businesses relied on colocation centers, which were unreliable, leading to investments in secondary sites and disaster recovery policies.
- Cloud computing introduced flexibility and speed but also complexity, making systems interdependent.
- SaaS proliferation increased reliance on third-party services, making redundancy across multiple regions impractical.
- Old paradigms of redundancy in secondary sites are outdated; focus on using cloud services correctly.
- Achieving high availability (five nines) requires significant investment in talent, standardized patterns, and disciplined engineering culture.
- Legal and compliance language around 'secondary sites' needs updating to reflect modern cloud architectures.
- Resilience is costly; businesses must assess their needs and invest accordingly.
