We compare the performance of the community, NGINX Open Source, and NGINX Plus Ingress Controllers in a dynamic Kubernetes cloud environment. As the number of Pod replicas scales up and down, only the NGINX Plus Ingress Controller doesn't incur high latencies.
Design: Design phase starts with the design in the baseline spiral and involves architectural, logical design of modules, physical product design and final design in the successive spirals. Construct: Construct phase refers to development of the final software product at every spiral. In the spiral when the product is just thought and the design is being developed, a Proof of Concept (POC) is developed in this phase to get the users’ feedback. Then in the successive spirals with higher clarity on requirements and design a working model of the software called build is developed with a version number. These versions are sent to the users for feedback.
