+# Scenario Definition for EshopOnContainers
+
+To use the simulation framework for microservices you have
+to specify a scenario/workload using json (configuration) files.
+
+The configuration files consist of:
+
+- operations: a HTTP request 
+- transactions: multiple operations sequentially chained together
+- scenario: specifies which transactions are run and other workload
+  configuration like distribution, arguments the transaction should use etc.
+  
+  
+The scenario should simulate a workload the microservice application would
+experience during a given timespan in production.
+
+
+
+## Scenario for eshopOnContainers
+
+Arguments and Dynamic Variables for Transactions:
+- userId
+- productId
+
+
+Transactions:
+- Customer reads items, adds item to basket, checkouts basket
+- Customer adds item to basket, removes again, logs out
+- Price update transaction
+- Stock replenished for catalog item
+- Catalog item is removed
+- create Order draft
+- Order cancel
+
+
+
+Workload configuration:
+- dataskew on catalog items (distribution of which items are accessed/bought)
+- distribution between different transactions
+- how many concurrent transactions
+- how many total transactions to be executed
