1 Assessing the readiness to move into cloud Marisa Escalante CloudComp 2012 Wien, Austria, September 24 26, 2012
2 Brief Introduction
3 TECNALIA Largest Research Center in Spain, with 1500 researchers, mostly located in the Basque Country Result from the merging of 8 Basque Research Centers 6 Divisions (Industry and Transportation, Energy, Health, Innovation, Construction, ICT/European Software Institute, Technological Services) ICT Division composed of 6 Business Areas IT competitiveness Service Industry Entertainment & Media Telecom Optima Computer Vision
4 Assessing the readiness to move into cloud Approach to assess the maturity of an application and the convenience of migrating to the new cloud computing paradigm or not, based on quantitative indicators while always ensuring the company s business continuity
5 Cloud Computing: another Keyword? Cloud Computing: IT as a Service Cloud computing represents a major change in IT service architecture, delivery and consumption BUSINESS MODEL HAS CHANGED!!!!
6 Some challenges encountered while migrating to SaaS
7 Challenges 1. Necessary adjustments to the systems-to-be-migrated 2. Not all components can be migrated in the same way 3. Requirements come mostly from the legacy 4. Treatment of new features and additional requirements 5. Lack of support for the implementation of a service oriented architecture. 6. Multi-tenancy, monitoring, billing, security, SLA, QoS 7. Software provided needs to be managed and controlled in the provision phase generating trust in the consumer 8. Difficult to calculate the resources needed and the timeframe in which the ROI will be achieved
8 General Issues & concerns Is the cloud a suitable solution for me? Costs Feasibility Technology & business model How to adapt my applications to the cloud? Re-designing the architecture Re-modelling the application/data Base Re-engineering the code Which functionalities/modules should I add to my application for offering it as a service over the cloud? And what if I want to change my IaaS provider? CLOUD How can I assure that my IaaS provider is fullfilling the SLAs?
9 To overcome these challenges Our Approach
10 M2S: Migration To SaaS Software as a Service based Company Software as a Product based Company
11 M2S: Migration To SaaS Software as a Service based Company Pre-Migration Software as a Product based Company Pre-Migration
12 M2S: Migration To SaaS Software as a Service based Company Migration Pre-Migration Migration Software as a Product based Company
13 M2S: Migration To SaaS Software as a Service based Company Provisioning Migration Provisioning Pre-Migration Software as a Product based Company
14 M2S: Migration To SaaS Software as a Service based Company Pre-Migration Software as a Product based Company Pre-Migration
15 Pre-migration: Objectives Evaluate the feasibility of the migration, technically and in terms of business Maturity Assessment - Quadrant Know how mature our application is and how mature we want it to be in terms of business and technology Technical Feasibility Analysis Is it technically feasible? Current architecture vs. Future architecture Reusability degree, complexiti, coupling, dependencies Business Feasibility Analysis Is the migration worth the money? How big is the impact in my organisation? Do I have to change many business processes?
16 Pre-migration: Maturity Assessment (1/3) Questionnaires
17 Pre-migration: Maturity Assessment(2/3) - Current Technology - Future Technology - Current Business Model - Future Business Model
18 Pre-migration: Maturity Assessment(3/3) Business 100% revenues as SaaS. Helpdesk 24/7 multilingual. Online marketing and procedured. SLA + upgrades >60% revenues as SaaS. Helpdesk 24/7 limited. SLA and upgrading processes at high level (0, 3) (0, 2) 3 Tiers Multitenant 1 DB instance Pay per use Helpdesk 24/7 in English Updates not procedured Current situation Future situation 10% - 20% revenues as flat rate. Rest as licenses. SLA s on paper. +90% revenues in licenses. Rest in flat rate Maintenance and support as separate services. (0,0) Monolithic Licenses (0, 1) (0, 0.5) (0, 0.5) C/S Heavy client 3 Tiers Licenses No maintenance No updates (0, 1) (0, 2) C/S C/S Thin client (n-tiers sin Thin client (n-tiers with WS) + Multiple DB WS and SOA) + 1 DB instances instance + n application instances (0, 3) C/S C/S Thin client (n-tiers with WS and SOA) + 1 DB instance + 1 application instance + n tenants Technology
19 Pre-migration: Business Feasibility Analysis Cost-Benefit Analysis (CBA) Inputs Year Year Incomes Cost Customer Development Number of potential customer 1st year Analysis & developer 0 Annual Customer Increase (%) Price Operational cost Selling increase IaaS Provider Adquisition of new services of actual customers Training Maintenance/ Update Savings Helpdesk Deployment travels Marketing Development and maintenainde by one environment Total costs Non quality cost Costs Revenues Total Incomes Result ROI Measures Year 1 Year 2 Year 3 Year 4 Year 5 Net present value Return on investment 38,4% 57,9% 82,9% 105,7% 127,3% Payback (in years) 2,62
20 Pre-migration: TechnicalFeasibility Analysis Analysis of the source code: functions and parameters, complexity of the functions, code clones, usage of libraries, dependences with the proprietary development framework, internal components and other external components, analysis of the database queries, interface with other systems. High Level Analysis of the candidate functions or modules that might be exposed as services in an easy manner Analysis of the Database Schema and Tables
