How to make infinite moving clouds

So I want to have some clouds that slowly move over time and repeat with the camera and I’m have trouble. Should I also have a parallax script on the clouds or not? The cloud script I have right now doesn’t move with the camera and I just don’t like it too much, any other suggestions on how to do this? This is what I have at the moment.

  private float speed;
  public float minSpeed;
  public float maxSpeed;
  public float minX;
  public float maxX;

  private void Start()
	  speed = Random.Range(minSpeed, maxSpeed);

  private void Update()
	  transform.Translate(Vector2.right * speed * Time.deltaTime);

    if (transform.position.x > maxX)
      Vector2 newPos = new Vector2(minX, transform.position.y);
      transform.position = newPos;

I did repeating terrain script before. If you only change the terrain for clouds it would work just fine i believe. I have 3 terrains with size 500f which always append themselves in front of each other.
And If you want the clouds to move with camera/player child the clouds to camera and restrict rotation in editor.

public Transform terrain1;
public Transform terrain2;
public Transform terrain3;
public float speed = 15f;
public float terrainSize = 500f;
public float numberOfTerrains = 3f;
public float origXlocation = -250f;
public float origYlocation = -5f;
float z1;
float z2;
float z3;
Vector3 newposition;

// Update is called once per frame
void Update()
    newposition = transform.forward * Time.deltaTime * speed;
    terrain1.transform.position += newposition;
    terrain2.transform.position += newposition;
    terrain3.transform.position += newposition;

    z1 = terrain1.transform.position.z;
    z2 = terrain2.transform.position.z;
    z3 = terrain3.transform.position.z;

    //go to the end of 1st terain warp back
    if (z1 >= terrainSize)
        z1 = z1 - (numberOfTerrains* terrainSize);
        terrain1.transform.position = new Vector3(origXlocation, origYlocation, z1);
    if (z2 >= terrainSize)
        z2 = z2 - (numberOfTerrains * terrainSize);
        terrain2.transform.position = new Vector3(origXlocation, origYlocation, z2);
    if (z3 >= terrainSize)
        z3 = z3 - (numberOfTerrains * terrainSize);
        terrain3.transform.position = new Vector3(origXlocation, origYlocation, z3);
