​​Having one instance of an application running on a server is rather easy to achieve, but several questions typically arise when the number of user increase:

• How many users should be able to connect the same time?

• How fast should my app respond?

• How many instances should I run?

• How can I scale up?

​

When encountered, those questions can quickly become blocking issues (e.g. back-end not accessible within defined timeout).

​

Also operating several servers at once can be time consuming and error prone (consistency issues);

​

​Nalys DevOps toolbox provides several solutions to set up and operate an infrastructure:

• Set up automation for provisioning and maintenance/operations (Ansible, Chef/Puppet, etc...)

• Use cloud services (AWS, Azure, GCP)

• Set up orchestrator on-premise (Nomad, Kubernetes)

• Set up autoscaling of systems using orchestrators
