Modernizing IT with Microservices
- 1. MODERNIZING IT WITH MICROSERVICES www.leanix.net Simon Barth simon.barth@leanix.net
- 2. Key Takeaways 2 Be able to reflect Microservices in your EA inventory & see the chances for EA 1 Take the 1st steps of a Microservice transformation Understand benefits of a Microservice architecture 2 3
- 3. 3 We asked over 100 high-profile IT experts about the usage, transformation and challenges of Microservices LeanIX Microservice Study 2017
- 4. 80% of surveyed companies bet on microservices 4 We use mostly microservices 9% New components as microservices, old monoliths maintained 38% We intend to transform existing monoliths to microservices 33% Microservices are no option 20% Does your company use Microservices?
- 5. Majority thinks still in long release terms 5 Max 1 per year Multiple times per year Multiple times per month Multiple times per week 17% 24% 51% 8% How often do you deploy new releases?
- 6. Companies who use microservices are much faster 6 Max 1 per year Multiple times per year Multiple times per month Multiple times per week # RELEASES ‘NO MICROSERVICES’ Max 1 per year Multiple times per year Multiple times per month Multiple times per week # RELEASES ‘MICROSERVICES’ Companies using microservices are faster
- 7. We will see a spike in microservice usage in 2017 7 71% 1/3 does not have planned to intensify their usage of microservices in 2017 29% 2/3 of companies will intensify their usage in 2017 Do you plan to intensify the usage of Microservices?
- 8. Legacy processes & lack of knowledge are the main hurdles that companies face 8 Politics Higher complexity Legacy processes Missing knowledge & people Microservices are no option Intend to transform to microservices New components as microservices, old monoliths maintained 11% 21% 33% 35% What are the major hurdles for adopting Microservices?

- 12. Transparency on responsibilities • Easy information on members in charge of Microservice • Modern collaboration possibilities on Microservice level Why Microservices and EA? • Complexity through high granularity • Challenging integration in legacy software ecosystem • Identifying spikes in over network communication between Microservices • Providing agile teams easy access to information about Microservices (e.g. responsibilities) • Manage diverse technologies LeanIX SolutionsMicroservices Challenges Smart Inventory • Reliable overview and transparency • Automatic updates of repository Reports and metrics to plan transformation • Identification of problems • Relations tracing and visualizations

- 17. Getting started 17 Read the full LeanIX Microservices Study 2017 (leanix.net/downloads) and share it with your colleagues Today Involve the right stakeholders and decide whether and how microservices could be leveraged more at your company. Start a small pilot. Build your repository. In the next three months Drive larger scale projects to transform monoliths to a microservice architecture. Make it a priority of your agenda After that
