Use AWS FIS to test the resilience of self-managed Cassandra
Database outages can have devastating effects on your applications and business operations. For teams running self-managed Apache Cassandra clusters, unexpected node failures or memory issues can lead to service degradation, data inconsistency, or even complete system outages. AWS Fault Injection Service (AWS FIS) is a managed service that you can use to perform fault injection experiments on your AWS workloads. In this post, we review how you can use AWS FIS to craft a chaos experiment to test the resilience of your self-managed Cassandra clusters running on Amazon EC2. This can help you understand your application’s ability to reestablish a connection to a healthy node.
Building resilient applications: design patterns for handling database outages
Database outages, whether planned or unexpected, pose significant challenges to applications. Planned outages for maintenance can be scheduled but still impact users. Unplanned outages are more disruptive and can happen at critical times. Even the most robust and resilient databases will inevitably experience outages, making application resiliency a critical consideration in modern system design. In […]
