In this session we will take a look on Azure Service Fabric and how we can create a web application using ASP.NET Core and microservices. During the presentation we will create a web application that will be hosted in Azure Service Fabric and use the most important capabilities of Azure Service Fabric.

WHAT ARE MICROSERVICES?

7. @ITCAMPRO #ITCAMP16Community Conference for IT Professionals

8. @ITCAMPRO #ITCAMP16Community Conference for IT Professionals
Software architecture style in which complex
applications are composed of small, independent
processes communicating with each other using
language-agnostic APIs
Microservices

9. @ITCAMPRO #ITCAMP16Community Conference for IT Professionals
WHY WE SHOULD USE
MICROSERVICES?

10. @ITCAMPRO #ITCAMP16Community Conference for IT Professionals
If we need a system that should be…
High decoupled
Small
Easy to replace
Focus on doing a small task
Independent deployment units
Symmetrical architecture

11. @ITCAMPRO #ITCAMP16Community Conference for IT Professionals
Evolution
Maintenance
is hard
Adding new
features is slow
Changes are
expensive
Technology
becomes the
obstacle rather
than enabler
App Modernization
