2 MONOLITHIC ARCHITECTURE Database App Server Search Signup Business logic is tightly coupled and deployed as one big chunk of code! Hard to scale, use a bigger computer? Hard to change, have to test the whole system together Hard to implement, developer team dependencies One part of the app can starve other parts if not designed carefully SOA helps to improve the monolithic application architecture Book Flight Flight History Split applications into services distributed over a network Each service consists of 1-n operations Often uses heavyweight protocols like SOAP Services often monolithic in nature Clients Let s see how Microservices might help here Software AG.

3 MICROSERVICE STYLE ARCHITECTURE Smaller services that do one thing really well Database Can deploy each service independently Can release each service independently Book Flight Search Signup Flight History Typically organized around business capabilities Container Container Container Container Gateway State is externalized Smart endpoints and dumb pipes Supports the DevOps culture Clients Clients Fits well with containers, like Docker Software AG.

4 CONTAINERS - DOCKER Let s you partition HW into virtual O/S instances Your app can run anywhere Docker can!!! On premise or in the cloud App Logic App Logic App Logic Run as many containers as you need Bins/Libs Container Bins/Libs Container Bins/Libs Container It is a self contained unit of deployment O/S parts SW Parts Docker Engine Your App code O/S Physical Hardware Reduces deployment time and improves accuracy What you build is what runs No more config errors deploying into already running servers Helpful for Zero Downtime scenarios Software AG.

6 PROS AND CONS OF MICROSERVICES Pros Distributed development Easier to build, test, fix and extend Easier to scale Resource efficient Service isolation Cons Requires more discipline to maintain service compatibility Can be more complex to deploy (more moving parts) Software AG.

7 SCENARIO BACKGROUND Build a set of Microservices using the webmethods runtime and an external DB to show how this can be done Uses Docker to create and run the Microservices Monitor running Microservice instances using Command Central The Scenario: Create a flight booking application (simplified for our purposes ) Features: Search for a flight Signup to book a flight Book a flight Show my historical and upcoming flights Software AG.
