****
|
||
|
|
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.
