Cloud: Session 3 - Defining the True Cloud

509 views

Published on

The term “the cloud” has been bandied about somewhat recklessly in the past, to the point where its true meaning has been diminished. But understanding the cloud is important – the public cloud offers benefits unavailable through other means of hosting your CRM application. Esteban Kolsky, an outspoken observer of both CRM and cloud computing, shares his views on the cloud, the things that AREN’T the cloud, and why it’s vital for every business to understand how the true cloud can benefit their business.

    20. 20. making the case for cloud computing E3 nterprise application storesmobile, social, user empowerment – all changed the gameusers aren’t putting up with big, complex applications – they want “apps” on iPadbest bet for support for all business is adoption of EAS, cloud is a must for that modelscalability, flexible interfaces, myriad device access via platform – all part of the cloudtwo-to-three year trend, if you haven’t started – better get going Tweet: #SCON12
    21. 21. making the case for cloud computing E4 xpansionplans for all business units in next few years include “cloud” and SaaSplans for IT over next three-to-four years include cloud infrastructureintegration, plans from partners, providers, suppliers, associates include cloud in nextfive yearsexpansion of any organization must include cloud going forward, no questionsif all other fails, cite the fact that competitors are expanding into cloud #Winning Tweet: #SCON12
    22. 22. making the case for cloud computing E5 volutionevolution of the world comes down to cloud, organizations have to adaptvendors are evolving their products from hosted, on-demand to cloudventures with partners, other organizations will demand cloud; three-to-four yearscustomers are demanding cloud –stirred up by microsoft “to the cloud” TV adswith differentiation of what is cloud and how to deploy in it, definitely a must-do Tweet: #SCON12
    23. 23. making the case for cloud computing E6 infrastructurreports say from 10% to 30% of IT budgets put on cloud infrastructurereports highlight more money spent by BU than IT on SaaS applications; continuingorganizations cannot leverage the cloud as an external service only, must integrateto make cloud work across organization, to retain security, to enhance integration – IT must be responsible for centralized cloud infrastructure; CEOs are seeing this Tweet: #SCON12
    24. 24. 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 model as described earlier MT, single-instance hard to scale; ST, multi-instance better licensing by usage, starting, is winner model for bizTweet: #SCON12
    25. 25. issues: private cloud short, simple, sweet any well done definition of the cloud specifically calls for open networks to support the cloud; private clouds violate core tenet of cloud 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 itTweet: #SCON12
    26. 26. 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 ideaTweet: #SCON12
