defining the cloud by “the book”cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically the internet)

cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction

defining the cloud, the “purist” way
• leverage, mashup parts of history, current definitions– distributed computing– single instance with replication– uses systems management– computing as a service– separation into three layers– open network– connected and integrated– measured by the usage, not by the user– public, public, and public

scalability: three sustaining pillars
design for scalability
in the cloud
scalability must occur
in two ways – up
and out
define scalability by
CapacityAvailabilityPerformance
cloud scalability
the entire concept of cloud computing was conceived for scalability sake

conomicseasiest part of the equation: someone else hosts hardware, software,
maintenance
anyway to look at it, remote, distributed computing is cheaper
move from CAPEX to OPEX is very attractive to managing stakeholders
cloud ROI traditionally done by comparing IT budgets to cloud expenses

scalability, integration are cheaper and easier, security is still under (hot)
debate

lasticity
inherent to cloud architectures
makes case for scalability, high-availability, failover planning
done wrong – remember the failure of amazon EC2 and the
problems it caused
is a scale-out model in single-tenancy, multi-instance, that cannot be
tested
requires systems management for proper instance maintenance

nterprise application stores
mobile, social, user empowerment – all changed the game
users aren’t putting up with big, complex applications – they want “apps” on
iPad
best bet for support for all business is adoption of EAS, cloud is a must for that
model scalability, flexible interfaces, myriad device access via platform – all
part of the cloud two-to-three year trend, if you haven’t started – better get
going

plans for all business units in next few years include “cloud” and SaaS
plans for IT over next three-to-four years include cloud infrastructure
integration, plans from partners, providers, suppliers, associates include cloud
in next five years
expansion of any organization must include cloud going forward, no questions
if all other fails, cite the fact that competitors are expanding into cloud

volution
evolution of the world comes down to cloud, organizations have to adapt
vendors are evolving their products from hosted, on-demand to cloud
ventures with partners, other organizations will demand cloud; three-to-four
years
customers are demanding cloud –stirred up by microsoft “to the cloud” TV ads
with differentiation of what is cloud and how to deploy in it, definitely a must-
do

infrastructurreports say from 10% to 30% of IT budgets put on cloud infrastructure
reports highlight more money spent by BU than IT on SaaS applications;
continuing
organizations cannot leverage the cloud as an external service only, must
integrate
to make cloud work across organization, to retain security, to enhance
integration – IT must be responsible for centralized cloud infrastructure; CEOs
are seeing this
issues: hosted != on-demand != cloud• hosted: a vendor puts a web-interface to their apps
– MT (multitenancy) is a big deal here– licensing is by the user, as usual– reduced functionality or poor performance by comparison
• on-demand: vendors leverages SaaS, PaaS model– web interface– MT benefits vendor; not so much clients– usually SaaS and PaaS “all in one” failing to leverage cloud
• cloud: three layer distributed computing model– MT, single-instance hard to scale; ST, multi-instance better– licensing by usage, starting, is winner model for biz
issues: private cloud• short, simple, sweet
• today’s private cloud is used as a bridge between client-server, web-based, on-demand, and SaaS worlds to get to the real cloud infrastructure
• use if you must, you are better off planning around it
any well done definition of the cloud specificallycalls for open networks to support the cloud;private clouds violate core tenet of cloud
your next steps
• define the cloud (for you)• take charge of your existing “cloud” initiatives
– across stakeholders– make case for central IT control
• setup 3-5 years strategy and investment• get going, do your infrastructure while you
leverage SaaS and on demand solutions• learn, implement, learn, implement – you get the
idea
let’s talk…
