Summary
In this chapter, you explored what a data lake is and how a data lake can help a large-scale organization. You learned about various data lake zones and looked at the components and characteristics of a successful data lake.
Further, you learned about building a data lake in AWS with AWS Lake Formation. You also learned about data mesh architecture, which connects multiple data lakes built across accounts. You also explored what can be done to optimize the architecture of a data lake. You then delved into the different metrics that can be tracked to keep control of your data lake. Finally, you learned about lakehouse architecture, and how to choose between data lake, lakehouse, and data mesh architectures.
In the next chapter, we will put together everything that we have learnt so far and see how to build an app in AWS.
