Environment

• Need separate environments for Development, Testing, and Production.

• Development & Testing will have some % of sample data from Production.

• Testing and Production will have a similar HW environment. (Cloud / In house)

• Nice to have a similar environment for development.

• Track changes, indexes, and query changes are done in the lower environment.

• DR environment is part of the Production release.

• Suppose it's in-house; deploy it in different data centers. If it's cloud, deploy it in different regions.
