  • Secure Java Software Development: Embracing Security by Design

    Introduction Security by Design (SbD) is a methodology that prioritizes security throughout the entire lifecycle of product development and deployment┬╣. In the realm of Java software development, where inherent security features like the Java Security package and Java EE Security API exist, integrating SbD principles becomes pivotal┬╣. Principles of Security by Design in Java 1.…

  • Scaling Applications on Kubernetes with Monitoring, Backup, and Storage

    Kubernetes, a platform for managing scalable, containerized applications, employs horizontal and vertical pod autoscaling for application scaling. It also uses tools like Prometheus for monitoring, Velero for backup and restore, and Persistent Volumes (PV) and Persistent Volume Claims (PVC) for storage. Utilizing these features, alongside proper monitoring and backup, can significantly enhance application performance, reliability,…
