+.Service mesh and microservices networking
+****
+We will be trying to create a swarm implementation that will allow communication between all of the members/nodes.
+
+[NOTE]
+====
+
+.Imaging a swarm
+image:./Swarming2.png[alt="Swarm"]
+
+To undertand this better lets look at the picture bellow and imagine that red dots are iot devices that can send and receive and black ones are clients that gather data.
+
+.Architecture of swarm communication

+
+- Red Node: Server/Client and Gateway Role
+- Black and Red Node:  Client Role
+====
+
+
+
+*To make our life easier at this task we will be using the following tools...*
+
+* Docker   image:link_icon_16.png[link="https://en.wikipedia.org/wiki/Docker_(software)",window=_blank]
+* Ansible image:link_icon_16.png[link="https://en.wikipedia.org/wiki/Ansible_(software)",window=_blank]
+* NodeJS  image:link_icon_16.png[link="https://en.wikipedia.org/wiki/Node.js",window=_blank]
+* VueJS   image:link_icon_16.png[link="https://en.wikipedia.org/wiki/Vue.js",window=_blank]
+* Redis   image:link_icon_16.png[link="https://en.wikipedia.org/wiki/Redis",window=_blank]

+
+== General info:
+
+=== Timeframe:
+This is a project that will be deleveloped thoughout the semester 2021.
+
+=== What will i learn?
+You will learn to code, coordinate and orchestrate a swarm of self-acting nodes.
+
+=== What tools will I need
+
+Internet και ένα laptop ή σταθερό υπολογιστή
+
+tools klp lai oti allo softwariko tha to kanpume mazi kata tin anaptixi
+
+gia to synolo ton tools 
+Please reffer to the  tools section below.
+
+=== What students can take this course
+Any student with basic knowledge of networking and computer programming should be able to cope with the needs.
+
+=== How is the course going to take place
+
+The course will be divided into following parts
+
+* A list of videos, asciinemas and instructions explaining the project 
+
+* lectures BASED ON THE VIDEOS for deeper analysis and questions
+
+* and a Gitter for further conversations kai na  λύσεις οποιαδήποτε απορία σου απευθείας
+
+=== Will there be some kind of exam/certificate? What will i gain?
+
+* The will NOT be an exam or certificate.
+* You will gain contributions in form of commits and merge requests into larger projects, which you can then add to your C.V. and upgrade it.
+
+TIP: Just to give some context, *contribution of code is regarded as the most important factor when choosing a software engineer*, thus making the course very helpful for future employment
+
