While the hype surrounding “NoSQL” (non-relational) database technology has become deafening, there is real substance beneath the often exaggerated claims. But like most things in life, the benefits come at a cost. Developers accustomed to data modeling and application development against relational database technology will need to approach things differently. This webinar will highlight the differences between a distributed document-oriented and relational database, the implications for application development and tips and tricks that will ease the transition from relational to NoSQL database technology.

2. WHY NOSQL?
“ Zynga’s games serve over 235 million active users per
month. We depend on technology from Couchbase to make
that possible. We have improved the performance and
availability of our games while reducing hardware and
administration costs. We will continue to transition our data
from relational databases to Couchbase technology.

Common characteristics of these “NoSQL” technologies
• No schema required before inserting data
• No schema change required to change data format
• Auto-sharding without application participation
• Distributed query support
• Automatic data replication across servers and regions
Very few organizations want to (fewer can) build and maintain database technology. Couchbase
was founded to create packaged, commercially-supported NoSQL database products.

9. Couchbase is consistently fast
Decouple application performance (user experience) from sketchy database I/O.
Application Server
Fast.
Memcached
Memcached, the most widely deployed in-memory caching technology on the planet, is built in to
Couchbase, enabling consistently low-latency data reads and writes. We wrote most of memcached.

10. Couchbase is elastic (scales out for increased capacity)
Grow with linear cost, constant performance and without downtime
Application Server
Elastic.
Expanding (or contracting) a Couchbase cluster is effortless; and requires no application downtime.
Other NoSQL solutions require complex configuration and application downtime.

Membase has proven itself in multi-hundred node deployments at Zynga, AOL and others. There is
a BIG difference between a 20 node and a 750 node cluster. Couchbase is the only NoSQL solution
that can scale, and remain manageable, from a single node to a multi-hundred node cluster.

incremental improvement in processing time
translates to huge benefits in our ability to more effectively serve the
ads needed to meet our contractual commitments. Traditional
databases lack the scalability required to support our goal of five
milliseconds per read/write. Creating user profiles with Hadoop, then
serving them from Couchbase, reduces profile read and write access to
under a millisecond, leaving the bulk of the processing time budget for
improved targeting and customization.

As long-time users and members of the Memcached community, we have

extend memcached clearly matched with their vision and we’ve worked closely with

performance and availability of our games while reducing hardware and
