Technology overview for Lambda Architecture

As explained briefly earlier, Lambda Architecture is a pattern with well defined guidelines and is technology agnostic. Looking at its various components/layer, any technology can be brought in to do the required job.

With, emergence of various cloud providers, you could even get ready-made components in cloud (many are cloud dependent) which actually implements the Lambda Architecture. In this book, we are marching ahead to actually create a Data Lake in which the lambda pattern just covers one layer, called Lambda Layer.

Since there are so many choices for technologies, the future chapters are a bit opinionated. When we make each technology, we would give the rationale for our choice, but keeping it as open as possible. We would also give our other technology choices, so that if needed, these technologies can indeed be swapped by the reader if required. Having said that, we will actually implement the Data Lake using the selected technology. The...
