Vertical Autoscaling with Cassandra: A Deep Dive into Scalability and Optimization

PostgreSQLCassandraApache FoundationVertically Autoscaling

Cassandra, a highly scalable NoSQL database, is renowned for its horizontal scaling capabilities, allowing seamless performance improvements by adding nodes. However, horizontal scaling often involves data migration, which can be time-consuming and complex. In contrast, vertical autoscaling offers a compelling alternative by adjusting resources on a single node, avoiding data migration and enabling flexible resource management. This article explores the nuances of vertical autoscaling in Cassandra, its technical challenges, algorithmic design, and practical applications, with a focus on optimizing resource utilization in Kubernetes environments.

In modern access control systems, the evolution from Role-Based Access Control (RBAC) to Attribute-Based Access Control (ABAC) represents a critical shift towards more flexible and context-aware security models. While RBAC provides structured role hierarchies, its limitations in handling dynamic contexts and scalability issues have driven the adoption of ABAC. Apache Fortress emerges as a pivotal solution, bridging the gap between RBAC and ABAC by integrating attribute constraints into role activation. This article explores the integration of ABAC with RBAC, focusing on Apache Fortress’s implementation and its practical applications.
