Please tell us a little more about your goals for making improvements to this part of the yard so that we can better answer your question.

I think the first thing is to direct your water and drainage. Perhaps a french drain or similar. You may want to consider adding a few small plants to help hold the soil as well. If you go with concrete, add a dye to stain it or stamp it - some type of decorative addition to make it more appealing since concrete is rather boring.

I agree about addressing the drainage and water flow first, especially if you plan to add concrete. We had a concrete patio for years and we loved it. It was inexpensive and we painted it a pretty color, however we just tore it up and put down pavers, because the ground underneath settled so badly, everything cracked. We put pavers down instead, because if more settling does occur, we can lift them in the areas needed, add more sand or base and put them back. With concrete, once it's cracked, there is no fixing it.

You could cement it and make a small little area on the end the water can sit in and run down like a small trench but like 3 inches wide just for the water run off
