9 Evolution of open source drivers, advantages *Primary/initial drivers and benefits of open source: -Cost savings through not paying license fees -Cost savings through not having to manage licenses -Rapid, easy availability of tools for developers and teams *Secondary/ongoing drivers and benefits of open source: -Time to release, time to deploy, time to market -Quality and uptime, performance -Innovation

10 Industry Trends 10 Black Duck 2013

11 Explosion of Data More Data, More Hunger... Internet of Things Mobile Digital Information created, captured, replicated... Tenfold growth over last five years surpassing 3 zetabytes in 2013 Industries look to FOSS for horizontal scalability 11 Black Duck

12 Open source in today's top trends *Cloud computing (Linux, Xen and KVM hypervisors, Tomcat and JBoss app servers, open source databases) *Big Data (Hadoop, Cassandra, memcached, NoSQL dbs) *DevOps (Chef, Puppet, CFEngine, Salt, Juju) *Mobile (Android, PhoneGap/Cordova, WebKit)

13 Open Source the Foundation of Innovation 13 Black Duck 2013

14 Rise of the user in communities Not only Web 2.0 and technology companies, but large enterprises including financial services, insurance, retail, manufacturing, media, healthcare, academic and public sector organizations are all heavily leveraging OSS components (whether they know it or not). Large users are sharing data and best practices i.e. large telecoms working together to solve common challenges and problems, expanding ecosystems. Software developers, engineers, productivity teams and business units all frequently prefer open source software for free and fast availability, customizable, modularity and extensibility.

16 Trends Coexisting Feast and Famine Abundance Over 2,000 repositories 100s of forges Maturation and proliferation causing: Balkanization Sourcing and evaluation challenges Brand confusion Scarcity Those same developers that drive abundance are themselves, scarce Demand is outstripping availability 16 Black Duck 2013

17 Legacy Migration Legacy Proprietary Software Open Source Software 17 Black Duck 2013

18 Legacy Migration Trends Organizations face mounting IT costs, limited budgets IT and operations Software development for enterprise and embedded For two decades, open source held promise Lower acquisition costs, lower TCO Increasing maturity and technical coverage Finally, open source delivers Solutions in infrastructure, development, now applications Available commercial support for most types of software 18 Black Duck 2013

19 Legacy migration beyond APIs Are open APIs the new open source? Not really both open APIs and open source software can be critical to successful technology deployments and initiatives. Recent research on OpenStack = open source software and availability of source code was critical for integrating and interfacing with existing and legacy infrastructure and investment, particularly among large enterprises.

20 The Path from Legacy to Open Source Legacy Software Catalog S/W Portfolio Rate / Rank Complexity Technical Opportunity? Yes No No No Commercial Support? Yes Yes Yes Commercial Open Source Meets $$ Criteria? Meets Risk Profile? Deploy OSS No Self- Support 20 Black Duck 2013

21 Migration Factors Candidate Identification End-of-life and end-of-contract High annual spend / license creep Declining internal usage? Challenges Technical complexity and dependencies Supplier contractual issues Maturity of FOSS targets and support ecosystems 21 Black Duck 2013

22 Legacy Software Categories 22 Black Duck 2013

23 Migration Analysis - Continuum of Complexity Complexity High Medium-High Medium Medium-Low Low Description Much or all code leveraging legacy technology must be rewritten for migration. Legacy needs combination of re-writing and straightforward porting / reintegration Legacy stacks built on standard technologies but with potential proprietary hooks and dependencies Minimal legacy dependencies but no one single migration path One-to-one porting with no/limited changes. Re-build/re-link/reconfigure L M H 23 Black Duck 2013

24 Migration Complexity Explained High Migration Complexity Much or all code leveraging legacy technology must be rewritten for migration Issues Proprietary APIs and application use of them Custom features and frequent customization to meet business requirements Example: Reporting Software Typical business reports (from DB or BI suite) written either using GUI or proprietary reporting language In most cases, report migration demands complete rewrite of each report in use H 24 Black Duck 2013

25 Example Distribution of Legacy Migration Opportunities Annual Spend High $10M High Complexity Business Intelligence & Reporting Moderate ~ $100K Web Servers Data Warehouse Enterprise DB Scientific Computing Web Portals Source Code Management SQL Databass Virtualization Operations Low Complexity In-Memory Data Base Logging & Monitoring Compilers Search Low < $10K 25 Black Duck 2013

26 Lock-in Risk for New Solutions Low Multiple sourcing/support channels for OSS Comparable/identical core functionality among solutions Standards-based or de facto industry standard itself Medium Attractive/extensive feature sets diverge from alternatives Use cases vary widely Limited alternatives in software category High Only OSS solution available OSS solution tied to single vendor 26 Black Duck 2013

27 Conclusion Considerations not so different from legacy/proprietary selection criteria Commercial Open Source Suppliers offer COTS product, support Community interface (proxy) Migration ROI Optimization Complex, interrelated factors Apples-to-apple migration may not yield significant savings Avoid Vendor and Technology Lock-in Strive to adopt standards-based and industry-standard implementations Beware of extensions, enhancements and other secret sauces 27 Black Duck 2013
