Tiger: Next Generation Index Serving Platform for Bing

What is Index Serving?

“Microsoft Research”

http://research.microsoft.com/en-us/• Bing is serving billions of queries

every day• Each query searches for the best

webpages among billions of web documents

• It is the most critical infrastructure for the search engine

What is Tiger?• Tiger is the next generation index

serving platform for Bing• Leveraging Solid State Disks (SSD) to

deliver great performance improvements

• Translates to significant annual savings, and better user experience for Bing

• A close collaboration between Bing engineering teams and MSR Asia– Three researchers working almost full-time

for one and a half years among the product teams

– Demonstrates our commitment to leveraging research to improve Microsoft products

Data Center Connectivity• Challenges– Scaling: connect 100K-1M servers– Fault tolerance: failures are common– High performance: highly demanding apps – Low cost: commodity devices whenever

possible• Opportunity – Data centers owned by single org;

deployment can be easier than on Internet

• Packet forwarding in commodity switching ASIC– High performance and limited

programmability

• Low latency and high throughput interconnection

• Full programmability at server– Kernel module for low latency– User space for

programmability
