Created the architectural vision and guided the NSX teams to design and build out the NSX platform to meet the quality and scale demands of very large-scale customers. Have a very successful and impactful collaboration with product, development, and quality engineering teams. This has resulted in noticeable improvements in quality and scale over multiple NSX releases.
Selected projects include …
Data model and architecture unification: Lead the unification of the data model and the redesign of several critical components in NSX Controller. This was a very large-scale project involving more than thousand engineers in development and quality engineering over a period of about eighteen months. One of the key outcomes from this project was that NSX was able to handle almost twice the scale with much better performance.
Multi-region database replication: Created the architecture and design for enhancing CORFU (clustered datastore built and used by NSX) to be able to replicate data across multiple independent clusters. This was a technically challenging project as it involved replicating data across regions while maintaining consistency as required by the applications. Provided guidance and technical direction to the team during implementation phase that lasted about two years.
Federation: Architected the platform for federating NSX across multiple sites. Separated the membership and connectivity matrix of NSX sites/regions from the actual nsx data federation. This key architectural decision along with multi region database replication has enabled NSX federation solution to scale out to more than 64 sites or clusters.
Have mentored and enabled multiple application teams on how to build solutions using the NSX distributed platform.
