What should you choose before you set up the cache?
Pick the engine and version your app supports. Then decide how the app will connect and whether you need a particular AWS network configuration. Keep the original records in the database or service that already owns them.
How does Serverless pricing differ from node pricing?
Serverless charges for data stored over time and for processing units, which include compute and transferred data. Node-based plans charge for running cache nodes, with options that affect the bill. Compare your chosen engine, region, capacity and expected request sizes.
What do you need if you replace the cache?
Record the engine, version, connection settings and the app’s rules for missing and expired entries. If your data must survive, verify backup and restore support for the selected engine and setup. A cached copy of a page is often easier to rebuild than move.
How would you compare the bills for a quiet shop?
On paper, compare a fictional shop that is quiet most of the day with one that gets steady requests. Use the same cache engine and region for each cost estimate.
