In this chapter, we revisited the GoldenGate topology, this time from a design viewpoint. We discussed the different replication methods and architectures and the hardware associated with each one. Functional and non-functional requirements were evaluated against the cost of hardware resources, encouraging a mindful balance in the overall design. Finally, we concentrated on Backup and Recovery options that are often overlooked, but have huge importance in your GoldenGate implementation.
In the next chapter, we delve a little deeper into the configuration detail, discussing the range and scope of available options and functions that make GoldenGate such a powerful and feature-rich product.
