1. Introduction & Overview<\/strong><\/h1>\n\n\n\n

What is Data Service Mesh?<\/h3>\n\n\n\n

A Data Service Mesh<\/strong> is an architectural paradigm that provides secure, reliable, and observable data services communication<\/strong> across microservices or distributed systems. It decouples the data service communication logic (e.g., routing, access control, monitoring) from application logic, making it a critical building block in secure and scalable DevSecOps pipelines<\/strong>.<\/p>\n\n\n\n

\n

It extends the concept of a service mesh (like Istio or Linkerd) to data-layer communication<\/strong>, ensuring policies, encryption, governance, and observability are applied to data-centric traffic<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n

History or Background<\/h3>\n\n\n\n
    \n
  • Originated<\/strong> from the need to secure and manage communication across distributed apps.<\/li>\n\n\n\n
  • The concept evolved from Service Mesh<\/strong> technology popularized by Istio, Consul, and Linkerd.<\/li>\n\n\n\n
  • Data Service Mesh adds data awareness, access governance, and security compliance<\/strong> on top of traditional service meshes.<\/li>\n<\/ul>\n\n\n\n

    Why is it Relevant in DevSecOps?<\/h3>\n\n\n\n

    In DevSecOps, security is integrated into every stage of the development and operations lifecycle<\/strong>. Data Service Mesh:<\/p>\n\n\n\n

      \n
    • Ensures data access policies, encryption, and visibility<\/strong> are consistently enforced.<\/li>\n\n\n\n
    • Enables zero trust architectures<\/strong>, policy-as-code, and data compliance (GDPR, HIPAA).<\/li>\n\n\n\n
    • Supports audit logging and runtime data observability<\/strong> \u2013 key for DevSecOps and regulatory environments.<\/li>\n<\/ul>\n\n\n\n
