Answer 7

microservices

A cloud native application consists of microservices working together as a whole to comprise an application, yet each can be independently scaled and iterated through automation and orchestration processes.

Question 8

What are three key features of microservices?

Answer 8

Key features of microservices include: code can be updated more easily. Teams can use different stacks and different programming languages for different components. Components can be scaled independently of one another, reducing the waste and cost.

Question 9

What is a single-tiered software application in which the user interface and data access code are combined into a single program from a single platform?

Answer 9

Monolithic

A monolithic application describes a single-tiered software application in which the user interface and data access code are combined into a single program from a single platform.

Question 10

Describe an approach in which a single application is composed of many loosely coupled and independently deployable smaller components or services?

Answer 10

Microservices architecture
