Ask HN: What are your views on integration platforms in 2021?

There are a lot of ways to do integration and a myriad of products and ideas of how to make it right.

What do you see as pros and cons of point-to-point vs ESB integrations?

What have you used successfully?

In the ESB case, how do you stay out of vendor lock-in? In the p2p case, how do you stay our of a chaotic heap of mixed nuts?

How do you successfully develop, deploy and document your integrations?

Any input and insights are welcome :-)
