CVE analysis, compliance guidance, migration playbooks, and open source strategy from engineers who run these systems in production.
Multi-Cluster OSS Management: Operational Patterns for Enterprise Scale
Managing a single RabbitMQ cluster or PostgreSQL primary-replica pair is tractable. Managing dozens across multiple environments, regions, and business units requires systematic operational patterns — GitOps, centralised observability, and standardised runbooks — to avoid operational chaos.
Container Image Hardening: Reducing Your CVE Surface by 80%
Bloated base images are the single largest source of container CVEs in most enterprise registries. Switching to distroless or minimal base images and applying a structured hardening checklist can eliminate the majority of reported vulnerabilities before they ever reach production.
PostgreSQL Operational Runbook: Backup, Recovery, and High Availability
PostgreSQL's built-in backup and replication capabilities are comprehensive but require careful configuration to achieve enterprise-grade recovery objectives. We cover the full operational stack: base backups, WAL archiving, streaming replication, and validated recovery procedures.
Kafka Cluster Operations: Day-2 Management for Enterprise Deployments
Apache Kafka is operationally demanding at enterprise scale. Consumer group lag management, partition rebalancing, broker storage management, and topic lifecycle governance require systematic operational practice. Here is the day-2 playbook.
RabbitMQ Production Operations: Monitoring, Alerting, and Incident Response
Running RabbitMQ in production at enterprise scale requires more than deploying a cluster. Queue depth monitoring, memory alarm management, network partition detection, and a practiced incident response playbook determine whether a degradation becomes an outage.
Frequently asked questions
What topics does the OSSeva blog cover?
The OSSeva blog covers: CVE deep dives and technical analysis of vulnerabilities in enterprise open-source software, compliance and regulatory guidance for engineering and security teams, migration guides (Oracle to PostgreSQL, Tanzu to OSS RabbitMQ, Confluent to Kafka), EOL timelines and planning guides for major open-source projects, and operational best practices for RabbitMQ, Kafka, PostgreSQL, and Spring in enterprise environments.
Does OSSeva publish CVE analysis publicly?
Yes. OSSeva publishes technical CVE analysis for all remediations in our public vulnerability directory and expanded CVE deep-dives on the blog. These posts cover: the technical root cause of the vulnerability, how it can be exploited, which versions are affected, what the OSSeva patch does, and how to verify your deployment is fixed. These posts are designed for engineers who need to understand the vulnerability, not just apply a patch.
