Enterprises have organically created a legacy of data silos through short term
focused projects, mergers & acquisitions!
Data Lakes and Silos Abound
▪ Data lakes and critical data are often in a silo and challenging to access
▪ Consolidation of data lakes and silos are expensive and slow to complete
▪ Compute is everywhere

▪ Data volume, velocity and variety are avalanching - data doubles every two years*
▪ The business knows that data analytics/ML models allow them to compete
effectively*
▪ The Hadoop investment is being replaced by object (on prem and cloud)
▪ The enterprise is a multi cloud world and will remain so for some time
▪ Technical leadership wants the agility to run applications anywhere to sustain
operations offering users a transparent self-service experience
▪ Technical organizations struggle to keep up with data ingest and business demands
▪ Data is still not fully optimized yet there are many copies costing $$$$
* “The Fourth Industrial Revolution”, by Klaus Schwab

Alluxio’s Vision
"Orchestrate data for analytics and machine learning to enable
companies to grow and be agile regardless of where their data
and compute are located."
Quick start cloud adoption that optimizes cost that yields 2X –
5X analytics acceleration for –
● Fraud protection
● Research for treatments for diseases like COVID-19
● Uptime for all industrial and digital technologies we depend on

7.
What is Data Orchestration?
A platform that brings your data closer to compute across
clusters, regions, clouds, and countries.

Companies use Alluxio to …
• Gain faster results that matter to the business – advanced caching
technology
• Dramatically lower OpEx by eliminating data management and cloud
egress and compute costs – unified namespace and API translations
• Drop into existing on prem and clouds with zero programming

A Data Orchestration Approach

Approaches to Hybrid Cloud
▪ Simple tools available like distCP
▪ Works for workloads with easily
identifiable datasets
Issues
▪ Datasets for many workloads
cannot always be identified easily
▪ Significantly more data transfer than
workload requirements
▪ Additional copies are very hard to
sync back with master data
Performance can be dramatically
impacted due to cloud storage
limitations
Lift and Shift
Data copy by
workload
Compute-driven
Data Caching
▪ Migration may seem easier as no
application re-architecture needed
Issues
▪ If workloads are not made cloud-
native and elastic, infrastructure cost
can skyrocket
▪ If on-prem data copy needs to be
maintained, syncing cloud and on-
prem data can be hard
▪ Data pulled into cloud based on
compute requests
▪ Data is cached locally to reduce I/O
on remote clusters and is
automatically synced
Issues
▪ Less helpful for workloads that don’t
read data set more than once

Barrier 1: Prohibitive network
latency and bandwidth limits
• Makes hybrid analytics unfeasible
Barrier 2: Copying data to cloud
• Difficult to maintain copies
• Data security and governance
• Costs of another silo
Step 1: Hybrid Cloud for Burst Compute
Capacity• Offload on-prem cluster (both compute & I/O)
• Manage working set, not FULL set of data
• Local performance
• Automatic synchronization with on-prem changes
Step 2: Online Migration of Data Per Policy
• Flexible timing to migrate, with less dependencies
• Instead of hard switch over, migrate at own pace
• Moves the data per policy – e.g. last 7 days

18.
Alluxio at Adobe
Primary DC with large Hadoop Cluster out
of space, ad hoc SQL workloads
exponentially growing as analyst
headcount as reached 1800 ppl
PROBLEM
● 80% less network usage
● More stable infrastructure
● Lower costs
● Results come in faster
● Easier to scale
● Ability handle new analysts with no impact and increase response times
● Self-service for end-users
Leverage compute resources outside of
primary on-prem DC for multiple analytical
frameworks.
