CDNs require all elements of a web site to be served by the same CDN.

CDNs can stream large media files such as movies or music to clients.

CDNs are present in multiple locations to serve content close to clients.

CDNs serve huge numbers of clients with high bandwidth and low latency.

CDNs forward all requests to a backend server and never store content locally.

Tests may not be written by the same development team that wrote the tested code.

All tests are generated automatically from the tested source code.

Tests are written before the function / method is implemented.

The only acceptable reason to write a test is to prevent fixed bugs from occurring again.

Instead of testing software automatically, manual tests are performed and logged daily.

Microservices facilitate the replacement of the implementation of a specific functionality.

Microservices applications are hard to scale because microservice architecture allow only one instance of each microservice.

Integration tests for microservices are not possible until all microservices forming a specific application are completely developed.

Interaction between microservices can be slower that the interaction of similar components within a monolithic application.

Within one application, individual microservices can be updated and redeployed independent of the remaining microservices.
