Is AAVE part of Ethereum?

Could you please clarify for me: is AAVE considered a part of the Ethereum ecosystem? If so, how does it integrate with Ethereum, and what are the key features and benefits of this integration? Additionally, could you elaborate on the role of AAVE within the larger cryptocurrency and finance industry? I'm interested in understanding the significance of this relationship and how it might impact the future of both Ethereum and AAVE. Thank you for your assistance in clarifying this matter.
