Pillar 4 - Reliability

What is it about?

Reliability ensures that systems remain stable and available – even under failures or load spikes. In WAF++, this means building resilient architectures that tolerate failures and can self-heal.

What is being done?

  • Redundancy: Using multi-zone and multi-region architectures.

  • Backup & restore: Regular backups and tested recovery processes.

  • Monitoring: Tracking availability and error rates.

  • Incident response: Defined processes for rapid fault resolution.

What needs to be considered?

  • SLAs & KPIs: Availability must be measurable and contractually guaranteed.

  • Failover strategies: Automated switchover on failure.

  • Testing: Chaos engineering and disaster recovery tests.

Where is this headed?

  • Self-healing: Systems detect failures and resolve them automatically.

  • Predictive maintenance: AI-powered prediction of failures.

  • Always-on: Near 100% availability as the target.
