Qurami is a free app that helps users queue for services at various venues in real-time, providing venue details and ticket status updates. The document discusses a microservice architecture developed in Golang for deploying applications, highlighting features like hot-swappable components and scalable architecture. Additionally, it outlines the development process, including interface definitions and implementation details for the deployer microservice.

- 2. What is Qurami? Qurami is the free app that queues up for you
- 3. What is Qurami? Select the venue you are going to Choose from the venues in your area, or discover all the available venues
- 4. What is Qurami? A venue, at a glance Select the service of your interest, know the exact position of the venue, get its contacts
- 5. What is Qurami? Issue a ticket Qurami will inform you about the status of the queue, in real time!

- 27. Microservice implementation: main func main() { // parse some command-line parameters // such as service ID and environment ... deployer, err := servers.NewRPCServer( new(interfaces.JSONRPCInterface), Identifier, Environment, ) if err != nil { log.Fatal(err) } deployer.ServeJSON() ... // wait until an exit command is given }
- 28. Microservice implementation: jsonrpc interface func (i *JSONRPCInterface) Enqueue( r *http.Request, args *EnqueueArgs, reply *string, ) error { result, err := core.Enqueue(*args) if err != nil { return err } *reply = result return nil }
- 29. Microservice implementation: core excerpt ... func Enqueue(args *EnqueueArgs) QueuedCommandResult { var result QueuedCommandResult deployer, err := NewDeployer( args.Command, args.Repository, args.AppName, args.Branch, args.DestMachine, ) if err != nil { result.Queued = false result.Message = err.Error() } else { result.Queued = true result.Message = "Started " + args.Command go deployer.SetAndExecute() } return result } ...
