I would like to draw the following picture using tikzpicture. Could you please help me?

Thanks in advance.

This reproduces most of your screen shot but I did not have the patience to punch in the texts. You start with the interior of the cloud, fit the cloud around it, and then add the other things. The triple arrow can be conveniently done with a pic, trident, which I added here.

  \draw[->] (0,0) -- (0:{0.5/sqrt(2)});
  \draw[->] (0,0) -- (-45:0.5);
  \fill(0,0) circle[radius=2pt];

  • Could you please tell me how to add the dots between edges (sources and sinks) shown in the figure? – Sultan Alam Mar 10 '20 at 19:14
