This document discusses real-time data driven services in the cloud. It provides examples of business needs like adapting quickly to customer demands and scaling IT investments without risk. NoSQL databases like Apache Cassandra are presented as solutions to handle big data workloads across data centers with continuous availability and scalability. Cassandra's architecture and performance benefits are summarized. DataStax Enterprise is highlighted as a production-certified platform with analytics, search and multi-datacenter capabilities.

“I have to move as fast as my
market. I can‟t get slowed down
by people telling me this is
going to take six months. It‟s got
to be ready, quickly. No matter
what. And I need to adapt
quickly with my customers.

4. VP of IT: How Can I Scale Without Surprises?
“Given the explosion of data in the
enterprise, how can I scale my IT
investment to meet the demands of
my lines of business, without taking
on undue risk? (My choices are to
spend $10 million to scale what I‟ve
got versus do something new)”

Cassandra to replace a legacy Oracle

May 02, 2013
(AP) The company chose Cassandra from
DataStax for its flexibility to create and
manage data clusters quickly, particularly in
the cloud. Christos Kalantzis, Netflix's
manager of cloud and platform engineering,
explains that "solutions like Oracle don't run
very well on virtualized hardware ... the
architecture of Cassandra and the availability
and consistency tuning and scalability made it

12. What is Apache Cassandra?
Apache Cassandra™ is a massively scalable distributed open
source database.
Cassandra is designed to handle big data workloads across
multiple data centres with no single point of failure, providing
enterprises with continuous availability without compromising
performance.

13. Cassandra Architecture Overview
• Fast / Linear performance
• Elastic scalability
• No single point of failure
• Enterprise / multi-data center / cloud
data distribution
• Location independence – read and
write anywhere
• Tunable data consistency (per
operation)
• Familiar SQL-Like language – CQL
• Dynamic / Flexible schema
• Can store structured, semi-
structured and unstructured data
• Replication Strategies from Amazon Dynamo paper
• Data structure and storage design from Google BigTable
paper

14. Apache Cassandra Leading in Performance
“In terms of scalability, there is a clear winner
throughout our experiments. Cassandra
achieves the highest throughput for the
maximum number of nodes in all experiments
with a linear increasing throughput.”
Solving Big Data Challenges for Enterprise Application Performance Management, Tilman Rable,
et al., August 2013, p. 10. Benchmark paper presented at the Very Large Database Conference,
2013. http://vldb.org/pvldb/vol5/p1724_tilmannrabl_vldb2013.pdf

15. Who‟s using Cassandra?

16. Why We Exist
“I can create a Cassandra cluster
in any region of the world in 10
minutes. When marketing guys
decide we want to move into a
certain part of the world, we‟re
ready.”
Today‟s applications must be
always available and lightning
fast as they scale to previously
unimaginable levels.
Cassandra delivers both with a
beautifully simple and elegant
architecture.

17. What We Do Best
Cassandra was designed to do
things that are impossible in
other databases when it comes
to availability and
performance. Forget about
losing a machine here or there --
Cassandra delivers a world
where you can lose an entire
datacenter and still perform as
your customers expect.
“We have to be ready for disaster
recovery all the time. It‟s really
great that Cassandra allows for
active-active multiple data centers
where we can read and write
anywhere”
Jay Patel
Technical Architect at eBay
(Describing why they switched from legacy
relational architecture)

18. Without Breaking Your Budget
“To do what we need to
do today without
Cassandra would cost a
couple million dollars
more and would be
significantly harder to
manage operationally.”
