As businesses and other organizations increasingly depend on internet-based services, attention is being focused on creating reliable infrastructure that minimizes costly downtime. In this article, we will discuss three areas where improvements could lead to less downtime for your organization. These areas are monitoring and alerting, software deployments, and high availability.
High-availability architecture for zero-downtime operations connects business uptime goals, redundancy, data protection, traffic routing, safe deployments, autoscaling, observability, and failure drills.
Cloud region failure planning needs a new high-availability model because outages, geopolitical pressure, data residency rules, and provider concentration can all disrupt digital operations.
