Which of the following are characteristics of traditional monolithic services. (Select 2)
- A. Fixed capacity
- B. Low scalability
- C. Very light weight application
- D. Very fast deployment
Answer: A,B
Explanation:
The characteristics of traditional monolithic services are low scalability and fixed capacity. Monolithic services are applications that are built as a single unit, where all the components are tightly coupled and run in the same process. This makes them hard to scale, as they require more resources and coordination to handle increased demand. Monolithic services also have fixed capacity, as they are designed for a specific workload and cannot adapt to changing requirements or traffic patterns. Monolithic services are often slow to deploy, as they require updating the entire application for any change or improvement.
