What challenges and risks do organization often face when switching from a monolithic system to microservices?

Here are some of the top challenges that organizations face in their microservices journey:

• Managing Microservices. As the number of microservices increases, managing them gets more challenging.
• Monitoring.
• Embracing DevOps Culture.
• Fault Tolerance.
• Testing.
• Cyclic Dependencies.

What are the challenges faced in monolithic architecture leading to the adoption of microservices architecture?

Apart from scalability, monolithic architecture has other issues associated with it, such as fault intolerance, frequent downtime, technology adoption, high-risk deployment, higher testing time, modularity and so on. All these reasons force enterprises to refactor their monolithic applications to set of microservices.

What are the challenges of monolithic architecture?

Drawbacks of Monolithic Architecture

• This simple approach has a limitation in size and complexity.
• Application is too large and complex to fully understand and made changes fast and correctly.
• The size of the application can slow down the start-up time.
• You must redeploy the entire application on each update.

What are the implementation challenges of MSA?

Here are some of the top challenges that an organization face in their microservices journey:

• Bounded Context.
• Dynamic Scale up and Scale Down.
• Monitoring.
• Fault Tolerance.
• Cyclic dependencies.
• DevOps Culture.

What are the disadvantages of monolithic system?

Drawbacks of monolith architecture

• Tight coupling between components, as everything is in one application.
• Less reusability.
• Large code base; tough for developers and QA to understand the code and business knowledge.
• Less Scalable.
• Does not follow SRP (Single Responsibility Principle)
• More deployment and restart times.

What are the limitations of monolithic application describe?

Disadvantages of Monolithic applications: It becomes too large in size with time and hence, difficult to manage. We need to redeploy the whole application even for a small change. As the size of the application increases, its start-up and deployment time also increases.

What are the challenges in microservices debugging and troubleshooting?

But even with tools in hand, debugging microservices can be a challenge….Manually testing microservices happens in a step-by-step process:

• Validating each code branch.
• Digging into the latest code available.
• Making sure dependencies have been updated.
• Verifying database validity.
• Restarting the service.

What unique challenges does the use of microservices throw at software testers?

Key performance indicators cannot be applied to microservices.

No testing tools have been designed for microservices.

Services can’t be tested, only applications can.

Too many unconstrained variables and undefined performance objectives.

What are the disadvantages of a MicroService based architecture?

The Disadvantages of Microservices

• Microservices create different types of complexity than monolithic applications for development teams. First, communication between services can be complex.
• Interface control is even more critical.
• Up-front costs may be higher with microservices.
