The effectiveness, efficiency and legitimacy of outsourcing your data

WHY ARE THINGS SO DIFFERENT NOW?
Historic Cost of RAM
• 1950 $4 per individual transistor• 2014 $0.00000000125 per individual transistor• Equivalent to 3.2 billion times cheaper• You would probably expect remarkable things
to be happening under these extraordinary circumstances
• And they certainly are…
DOING MORE FOR LESS – EFFECTIVENESS AND EFFICIENCY
Long Term Trends Supporting Cloud Approach
• Open Systems and Open Source• Declining cost of kit• Maturity of tools• Density of applications• Different style systems integration• Different and radically more efficient styles of
development• Cloud and Open Source is the Internet’s style
of development
REASONS GIVEN FOR NOT USING CLOUD
Reasons NOT to use cloud 1
• Fear– Can be weird, but ponytails know things suits don’t
know about systems building• Security– virtual networks, strong separation, multiple levels of
virtualisation, encryption end to end, – always a dilemma between access, usefulness and
security– Not all data can go on a public cloud, all data can
probably go on a private cloud, need to decide case by case
– Isolated data is safe (and useless)
Reasons NOT to use cloud 2
• Reliability– Cloud architectures mirror highly reliable systems,
and commodity architecture failure rates very low• Availability– The most available systems (Google, Amazon,
Azure) are private clouds– Individual cloud building blocks can fail, but whole
cloud cannot– Open Cloud means portability between cloud and
use of multiple clouds
Total cost of ownership
• Argument is that somehow supported commodity systems on enterprise hardware prove cheaper in the long run
• Eh?• Lose licensing costs for much software• Easily reconfigured/developed• Commodity hw• (importance of partnerships, different style
of development – one that works)
Applications - Lose the Lock in
• Open Source and Open Cloud maximise supplier and application independence
• Move from Cloud to Cloud, and know it will work
• Standard interfaces throughout• Thin layer of particular applications on top• Revision and development assumed
REASONS FOR USING CLOUD AND HOW TO USE IT
Open Source and Open Cloud: Re-Use
Open Source and Open Cloud: Re-Use (Effectivenes and Efficiency)
• Open Source and Open Systems allows us to build and rebuild
• Don’t throw it away and start again for every new development
• Build on systems that are working and will carry on working
• Needs an awarenes of Open Source landscape and ecosystems
Towns, Cities and Regions which are ‘Open’
• Schoten– Only Open Source throughout, including phone
systems• Munich– Peter Hofmann, CIO– 2002-2012, de-MicroSofted City
• Swedish Association of Local Government– Joint ownership of all development– All open source based, though they don’t quite
reciprocate• Partnerships versus Applications and Solutions
Cloud Approach - Agile Teams
Different styles of development for Cloud(Effectiveness and Efficiency)
• Procurement is different– need good partners and partnerships– Retain or share your IP in systems
• Apps versus applications• Agile versus waterfall• Agile development partnerships with
reconfigurable and reusable systems• Fail quickly if the development must fail
What Cloud is and isn’t
• Think people don’t quite see the difference between cloud, virtualisation and just heaps of resources
• Cloud is obviously heaps of virtualised and virtualisable resources
• But it’s how those resources are organised and can be used
• But also important that it’s an Open Cloud– Applications can migrate between Open Clouds
What’s really important
• But actually if you’re a cloud builder, and even if you’re a user, cloud is the cloud toolset
• Powerful tools are what has changed, tools lets us remember how we built things and lets us automate the building
• And if we can automate the automation (and we can), then we build huge power with each turn of the screw
Why cloud matters now
• Allows builder and user to deploy any virtual configuration
• Any estate can be virtualised to any degree and level
• Cloud allows those next level virtualisations• Any estate and its complete combination of
data and programme config can be written down for the toolset to generate once or any number of times, anywhere, on any target
What is Our Cloud?
• It’s an infrastructure cloud– Commodity hw– Open Source sw
• Compute based on OpenStack– Original development between NASA and Rackspace– Specifically to be an Open Cloud– Uses commodity compute boards– Amazon EC2 compatible interface– vSphere like controls– More configurable
What is Our Cloud
• Storage Cloud– CEPH, California based development– Uses commodity SATA discs– S3 compatible interface
• Is high performance/high throughput– Because so many nodes– Specialist data warehouse appliances will be
quicker– But 10x price (or more)
Why These Choices
• Very large scale Open Source project– it will continue to be developed– Mainstream
• Low cost base– Reduced licensing costs for base sw– Can use ‘any’ hw
• Incredibly powerful tools– We improve and automate
What Cloud and Open Source Show Us
• The key is not the kit, probably not even the software is most important
• It’s the partnerships you build which can produce solutions– get reconfigured – then produce a revised solution, again and again– And reconfigurable partnerships
• That’s how world wide Open Source projects work
• Very loose self managed projects outperform traditional projects by a mile
Effectiveness, Efficiency and Legitimacy
• Effectiveness, better systems, available, usable, reconfigurable
• Efficiency, direct cost savings, time savings• Legitimacy, it’s a responsibility for anyone
involved in procurement, public or private to start to engage with one of the quietest, most remarkable revolutions, it draws its legitimacy from its own results.
