How can I determine if I am running locally on my PC or on the cloud?

Using MVC3 and I'd like to determine if I am running locally or deployed to the cloud?

This is what I use

public static class Azure
{
    private static bool m_IsRunningAzure = GetIsRunningInAzure();

    private static bool GetIsRunningInAzure()
    {
        Guid guidId;
        if (RoleEnvironment.IsAvailable && Guid.TryParse(RoleEnvironment.DeploymentId, out guidId))
            return true;   
        return false;      
    }

    public static bool IsRunningInAzure()
    {
        return m_IsRunningAzure; 
    }

    private static bool m_IsRunningAzureOrDevFabric = GetIsRunningInAzureOrDevFabric();

    private static bool GetIsRunningInAzureOrDevFabric()
    {
        return RoleEnvironment.IsAvailable;
    }

    public static bool IsRunningInAzureOrDevFabric()
    {
        return m_IsRunningAzureOrDevFabric;
    }
}
