• Designed, developed, and deployed as a single unit.

• Overwhelmingly complex for most of the real-world business use cases, which leads to nightmares in

maintaining, upgrading, and adding new features.

• It’s hard to practice Agile development and delivery methodologies. Since the application has to be built as a

single unit, most of the business capabilities that it offers cannot have their own lifecycles.

• You must redeploy the entire application in order to update any part of it.

• As the monolithic app grows, it may take longer and longer to start up, which adds to the overall cost.

• It has to be scaled as a single application and is difficult to scale with conflicting resource requirements.

• One unstable service can bring the whole application down.

• It’s very difficult to adopt new technologies and frameworks, as all the functionalities have to build on

homogeneous technologies/frameworks.
