Memgraph is a high-performance, in-memory graph database that powers real-time AI context and graph analytics at scale.

Vector search finds what's similar. Graph reasoning finds what's connected โ€” following relationships, dependencies, and hierarchies that similarity alone can't capture. Modern AI systems need both, and Memgraph is the graph layer - surfacing precise structural context with full audit trails in sub-millisecond time.

It serves as the graph engine for GraphRAG pipelines, AI memory systems, and agentic workflows โ€” a single high-performance layer for any system that needs structured, connected context. The same in-memory architecture drives real-time graph analytics for fraud detection, network analysis, infrastructure monitoring, and other operational workloads where milliseconds matter.

NASA uses Memgraph to connect people, skills, and projects across the agency into a queryable knowledge graph that powers real-time expert discovery and workforce planning. Cedars-Sinai uses it to link genes, drugs, and clinical pathways in an Alzheimer's knowledge graph spanning over 230,000 entities that drives drug repurposing research and multi-hop biomedical reasoning. Organizations across cybersecurity, finance, retail, and other knowledge-intensive domains rely on Memgraph for the same reason: sub-millisecond graph traversals for the structured context and real-time insight that modern systems demand.

Possible disadvantages of Apache CloudStack

  • Steep Learning Curve
    Due to its vast array of features and complex architecture, it can be challenging for newcomers to grasp and configure efficiently.
  • Community Support
    While there is a community for support, it might not be as extensive or responsive as commercial solutions with dedicated support.
  • Limited Advanced Features
    Compared to some commercial cloud platforms, Apache CloudStack may lack certain advanced features or cutting-edge integrations.
  • Upgrading Complexity
    Upgrading existing deployments can be complex and may require significant planning to ensure smooth transitions without downtime.
  • Customization Challenges
    Although highly configurable, customizing CloudStack for specific needs might require deep expertise and can be resource-intensive.

  • what do they use, or how do they do it..
    The big providers like AWS, GCP, Azure, all have fully custom solutions for the whole infrastructure. But there exist a number of open source projects which give you the ability to setup the basics (compute, storage, networking) on your own. A few such infrastructure projects I'm aware of: * Cloudstack * Openstack * Eucalyptus. Source: over 4 years ago

  • CI/CD Auto-Remediation: The Complete Guide for SRE and Platform Teams (2026)
    Auto-remediating into a worse state. The classic failure is auto-scaling a service to handle elevated error rates that are themselves caused by a downstream dependency. The service scales, hammers the dependency harder, and the dependency collapses. Fix: never auto-remediate without dependency-graph awareness.

  • Ask HN: Were Graph Databases a Mirage?
    Relational databases have a much longer history of development, and much more engineering time has went into designing RDBMS. It is not a surprise that they are mature on more levels. By looking at the age of a product, you can get a sense of how mature RDBMS systems are compared to most GraphDB projects.
