7 Steps to Avoiding Downtime
Blog post from PagerDuty
Ensuring high availability for applications involves adopting several strategic steps to mitigate the risks and costs associated with downtime, exemplified by Delta's costly IT outage. Transitioning to a microservices architecture allows for more resilient and independently manageable application components, reducing the risk of total system failures. Frequent and smaller releases, along with a strong emphasis on quality assurance (QA) throughout the development process, enhance application availability and competitiveness. A robust disaster recovery plan, supported by automation, ensures data redundancy and swift recovery in case of disruptions. Employing IT service management (ITSM) frameworks and incident management tools helps manage changes and alerts efficiently, minimizing mean time to resolution (MTTR) during outages. Additionally, deliberately inducing failures, as practiced by companies like Netflix, prepares teams to handle real-world downtime more effectively, ultimately fostering trust and loyalty among customers through improved app reliability.
