The document discusses the concept of a global data fabric that allows efficient collection, access, and analysis of big data across the globe, emphasizing features like low latency, affordability, and coordination between local and global operations. It highlights real-world applications, case studies, and technological advancements such as streaming data architecture and MapR's unique offerings in geo-distributed data management. Additionally, the importance of edge computing, hybrid cloud strategies, and the integration of IoT in various sectors, including telecommunications and manufacturing, are explored.

Imagine a future where …
You easily collect, access & analyze big data where ever you need it across
the globe in a seamless system under the same security & administration

5. © 2017 MapR Technologies 5
The future is here: Global Data Fabric
• Global data fabric lets you update business globally
• Local activities coordinate with global analyses
• Do this without requiring huge teams at each site
• Do this affordably, reliably, with low latency and at large scale
We’re here to explain how, but first: a real-world case study

A Year of Technical Credit, not Debt
• Streaming media delivery is inherently geo-distributed
• Must measure if you want to manage
– metrics need to be collected and processed locally
– and distributed back to central facility
• How?
Streams!

MapR Streams:
Geo-distributed data
plus separation of concerns

15. © 2017 MapR Technologies 15
Why stream?

16. © 2017 MapR Technologies 16
Mechanism for a Global Data Fabric: Streaming
• Streaming data is becoming mainstream
• Innovative technologies are emerging to handle and process
streaming data
• Stream-1st architecture is a powerful approach with surprisingly
widespread advantages

Revolution in Manufacturing: Smart Tools
• Respond quickly to new requirements
• IoT enabled “smart tools” on
manufacturing floor
• Reconfigurable factory
• Removes barriers to communication:
engineering, design, analysis,
manufacture in one space

Predictive Maintenance
• Streaming sensor data + long term maintenance histories 
• Machine learning model detects anomalous pattern
• “Failure signature” warns of need for maintenance before
damage occurs

Unique to MapR: Manage Topics at Stream Level
• Many more topics on MapR cluster
• Topics are grouped together in Stream (different from Kafka)
• Policies set at the Stream level such as time-to-live, ACEs (controlled
access at this level is different than Kafka)
• Geo-distributed stream replication (different from Kafka)

Global Namespace: Advantage for Geo-Distribution
• Enables program to refer to data anywhere
– On premise, in cloud, around the world
• Easier to manage: Supports separation of concerns
• Unique to MapR

38. © 2017 MapR Technologies 38
The Need for Cloud
• Fewer machines to purchase, flexibility regarding hardware
• Eases pressure on IT
• Cloud-bursting possible for short-term increase in computing
• Lets you optimize cluster usage (especially if you maintain
cloud neutrality)

Hybrid Cloud On-Premise Architecture
• Optimization of resources, but…
• Too complicated unless have a good platform for geo-distributed
data
• MapR is such a platform

41. © 2017 MapR Technologies 41
The Need for Containers
• To deploy exactly the same thing in many data-centers
• To get predictable behavior in production compared with testing
• Result: Docker-style containers becoming ubiquitous

45. © 2017 MapR Technologies 45
MapR Edge
• Small footprint cluster for remote processing
• Intended to run right next to the data producing device
– Unified end-to-end security policy
– Reliable replication to cloud and data center, even with occasional
connections
• Small but full MapR data services (files, tables, streams)
– Normal data protection (snapshots, mirroring, replication)
– Normal management capabilities (volumes, fine-grained access
control, monitoring)

Streaming in Telecom
• Data collection & handling happens at different levels
– tower, local data center, central data center)
• Batch: Can take 30 minutes per level
• Streaming: Latency drops to seconds or sub-seconds per level
• Ability to respond as events occur
• MapR Streams enables stream replication with offsets across data
centers
