+backend logic:
+comprises of multiple flows which should be broken into microservices in future:
+1. access to db
+2. access to elastic search
+3. access to cassandra
+
+// right now backend should not even have a main.
+// front end should directly call into this
+
+deployment will look as follows (later this will all change into different clusters)
+1. frontend process in a docker containr
+2. backend process in a docker container
+3. elastic search in a docker container
+4. cassandra/mongodb in a docker container
+
+// start all containers with -d flag so that they run in daemon mode
+
+for v.01
+frontend+backend will be one single service -- later this can be broken up into two microservices that will communicate via some messaging scheme
