Apache Cassandra is a highly scalable, open source NoSQL database system designed to handle large amounts of data across multiple commodity servers with no single point of failure. Apache Cassandra can be run as a single node but starts making sense when its run in a cluster setup. The system is optimized for high write throughput and is known for its ability to handle big data workloads with ease at super-low latencies.
It is not always possible or necessary for an organization to rely solely on cloud resources. For example, requirements might call for on-premises infrastructure for privacy reasons. Alternatively, some organizations might use both on-premises infrastructure and public cloud services provided by companies like AWS, Azure, or Google.
Root cause analysis (RCA) is a systematic approach to defining symptoms, identifying contributing factors, and repairing faults when problems arise. The process can be applied to virtually any problem in any industry, from NASA’s Apollo 13 mission to everyday tech problems that happen within modern IT departments.
