Serverless Microservices Architecture

Comment

Serverless microservices are cloud-based services that use serverless functions to perform highly specific roles within an application. Serverless functions, which execute small segments of code in response to events, are modular and easily scalable, making them well-suited for microservice-based architectures.

@Configuration
public class ApplicationConfiguration {
    private final Gson gson = new Gson();
    private ApplicationProperties properties;

    public ApplicationProperties getApplicationProperties()
    {
        if (properties != null)
        {
            return properties;
        }

        this.properties = getProps();

        return properties;
    }

    private ApplicationProperties getProps() {
        var parameterName = System.getenv("CONFIG_PARAMETER_NAME");
        if (parameterName == null || parameterName == "") {
            return new ApplicationProperties();
        }

        var ssmClient = SsmClient.create();

        String parameter;

        var getParameterRequest = GetParameterRequest.builder()
                .name(parameterName)
                .build();

        GetParameterResponse result = null;

        try {
            result = ssmClient.getParameter(getParameterRequest);
        }
        catch (Exception e) {
            throw e;
        }
        if (result.parameter().value() != null) {
            parameter = result.parameter().value();
            return gson.fromJson(parameter, ApplicationProperties.class);
        }

        return null;
    }
}
