The Forces of Disruption

The Forces Of Disruption

The Generic Dimensions of IT

u  All IT involves 4 components (only) •  Users •  Software •  Data •  Hardware

u  Change any one of these and the other three components have to adjust

u  Aggregate these and you get a process

u  Time will impose change anyway

u  We can also consider a larger field, since this applies to all systems not just IT systems

The Technology Layers

u  The buying impulse descends through the stack

u  The impact of technology change rises up the stack

u  This ensures the eventual “legacification” of all technology

The BuyingImpulse Goes

Down

TechnologyChange Rises Up

The TechnologyLayers

Technology Layer Perspectives

u  This simple model has a number of uses

u  For example, we can use it to depict the “aaS options”

u  More importantly we can use it to track disruption …

u  More of which later…

The aaS Possibilities

Disruption in The Technology Layers

u  Disruption (as innovation) can happen in any layer

u  Where it occurs, it will impact all layers above it

u  And it may also impact the layers below it (but less quickly)

u  There is no such thing as future-proof; but some technologies definitely live longer

The BuyingImpulse Goes

Down

TechnologyChange Rises Up

The TechnologyLayers

Mainframe Computer (Batch architecture)

On-line Interaction (Centralized architecture)

PC (Client server)

Internet (Multi-tier architecture)

Mobile (Service oriented architecture)

Internet of things (Event driven architecture)

Tech Revolutions

Note that all of these disruptive changes were driven by hardware innovation

Hardware Layer Disruption

u  SSD is now on the Moore’s Law curve

u  Spinning disk has almost popped its clogs

u  Memory grows and can be networked

u  CPUs still evolving: CPU and GPU merged

Hierarchical Memory

u  On chip speed v RAM •  L1(32K) = 100x •  L2(246K) = 30x •  L3(8-20Mb) = 8.6x

u  RAM v SSD •  RAM = 300x

u  SSD v Disk •  SSD = 10x

Note: Vector instructions and data compression

In-Memory Disruption

u  Memory will become the primary store for data (this impacts data flows)

u  Almost all applications are poorly built for this

u  Memory is an accelerator, as is CPU cache – this is becoming a factor

u  HP’s Memristor waits in the wings

Hadoop: Deceptive Impression Because Hadoop was built to run on 1000s of servers, there’s an impression that Hadoop needs such huge

clusters/grids

In reality the opposite is now happening, the number of servers is diminishing, which means that Moore’s Law still

operates

Putting a SoC in IT

u  It’s possible that the CPU-Memory split will vanish, possibly soon

u  This requires the emergence of the commodity SoC

u  There are already SoCs that run Linux

u  Grids of SoCs would replace grids of servers

Parallelism: The Imp Is Out of the Bottle

u Multicore chips enabled parallelism

u  It has changed the whole performance equation

u  It enabled Big Data

u  Big Data is really Big Processing

Some Architectural Principles

u  The new atom of data is the event

u  SUSO, scale up before scale out

u  Take the processing to the data, if you can

u  Hadoop is a component not a solution

Hadoop: Then, Now & Later

The Hadoop Ecosystem

u  Apache Projects: HBase, HCatalog, Pig, Hive, Flume, Storm, Sqoop, Nutch, Avro, Oozie, ZooKeeper, etc.

u  New commercial products: Actian, RedPoint, Attunity, Voltage Security, etc.

u  Languages and dev environments

Hadoop Usage

u  Data archive

u  Data staging & ETL

u  Data preparation

u  Analytics sandbox

u  Analytics platform

u  Database environment

The State of Play

Graphic from Allied Market Research

There are some straws in the wind here: it is being used everywhere

It’s a HUGE market Also VC investment is massive

Hadoop as a Clip-On

Data Lake, Refinery, Hub: In Overview

Think Logical, Implement Physical

Two Data Flows

Hadoop in the Technology Layers

Hadoop in theTechnology Layersu  Hadoop starts as a scale-

out file system with a one-dimensional development environment

u  It evolves with the addition of YARN to begin to occupy the OS & Sys Mgt layer

u  Analytics applications become synonymous with Hadoop

u  Hadoop is migrating through the stack

Hadoop as an OS

u  The Trail of OSes •  OS/360 -> OS/370 -> z/OS •  VMS •  Unix -> Solaris •  MS-DOS -> Windows •  Linux •  OS X -> iOS

u  OSes evolve in two ways •  Own development •  Third party add-ons

u  They create application ecosystems u  In time they make previous OSes

obsolete u  This is what Hadoop is in the

process of doing
