Research, Development, and Consulting
Thomas J. Watson Research Center, Yorktown Heights, NY USA



Arun Iyengar does research, development, and consulting into distributed computing, cloud computing, Web performance, as well as fault-tolerant computing and high availability at IBM's T.J. Watson Research Center. His work involves computer science research leading to publications and patents as well as software engineering leading to products, customer solutions, and open source software.

Arun's work has been incorporated into several products (by IBM and other companies) as well as commonly used open source software. His caching and load balancing techniques are widely used to improve performance for Web sites and distributed applications. He has also developed widely used techniques for dynamically generating Web content which have been incorporated into Web content management systems as well as a widely used method for preserving state on the Web without using cookies.

Arun has recently developed the following software:

  • His Universal Data Store Manager (UDSM) allows a computer program to access multiple data stores including file systems, SQL stores, NoSQL stores, and caches. A common interface is provided to make it easy for an application to easily switch between different data stores. The UDSM allows the performance of different data stores to be monitored, and a workload generator allows the performance of different data stores to be easily compared. Encryption is provided for data confidentiality, and compression is provided to reduce data sizes.
  • Enhanced data store clients (particularly for cloud-based data stores) which provide caching, encryption, and compression capabilities. His data store client library can be used for a broad range of applications in which these features are needed.

Arun is an IEEE Fellow, has won several Best Paper awards (see Selected Publications and/or Technical Work), has received the IFIP Silver Core Award, and has been named an IBM Master Inventor multiple times.
