+****
+We will be trying to create a swarm implementation that will allow communication between all of the members/nodes.

+.microservices architecture
+
+* a microservice performs a simple task
+** communicates with clients or 
+** other microservices
+*** communication mechanisms such as REST API requests or Websocket etc
+
+[NOTE]
+====
+
+* Microservices can include  any programming language you like
+** and with the orchestration tools they are easy to deploy and maintain
+
+ This architecture uses NodeJS and Redis microservices deployed as Docker containers
+====
+--
+
+
+=== Scalability
+
+You can scale your application by updating the number of replica nodes in the swarm cluster
+
+[source,yml]
+----
+...
+    deploy:
+      replicas: 15
+      placement:
+        max_replicas_per_node: 1
+        constraints:
+          - node.labels.region==regio1
+...
+----
+
+.Segmentation
+TIP: Dynamic infrastructure: services can scale up and down without waiting for each other.
+
+=== Availability
+
+No single point of failure.
+
+=== Security
+=== Configuration
