Microservices have changed the way I build apps in every way. Like in the old days, I don’t build everything as one big piece. Instead, I break it up into smaller, separate services. Each service helps the business in a certain way.
It’s easy to add more apps, which is a great thing. With the old method, it was hard to scale the whole thing because any changes affected everything. However, I can grow each service on its own with microservices. In other words, I put resources right where they’re needed, which saves money and makes things run more smoothly.

When it comes to how we use containers, Docker has really changed how we make software. By putting everything they need into these small, light containers, it’s much easier to package and launch apps. Our creation process is now smoother, and deployment works much better.
Even more is changed by Docker when we talk about microservices. The idea behind microservices is to make things separate and flexible, and Docker’s containerisation works great with that. It works great with our microservices design and makes managing it easy.
The Good
- Lightweight, fast, and efficient containerization.
- Easy to package and deploy applications.
- Widely adopted with strong community support.
The Bad
- Limited orchestration features compared to Kubernetes.
- Requires additional tools for orchestration and scaling.

Criteria for Evaluating Microservices Apps
It is important to take into consideration the following critical characteristics when analysing microservices applications:
- Scalability: Is it possible for individual servers to be scaled horizontally to handle changing loads?
- Fault Tolerance: How resistant are the apps to failures? What are the plans for a smooth degradation and recovery?
- Interoperability: Can microservices talk to each other and work with external systems and APIs without any problems?
- Monitoring and Management: What ways and tools are there for keeping an eye on performance, finding problems, and overseeing apps on a large scale.
Questions and Answers
When compared to monolithic systems, microservices are more flexible, scalable, and quick to respond. They let each service be developed, deployed, and scaled up or down on its own, which speeds up innovation and makes the system more resilient.
Some of the problems that need to be solved are handling the complexity of distributed systems, making sure that microservices can communicate reliably, making sure that data is consistent across services, and using the right monitoring and governance methods.
Kubernetes automates orchestrating containers, makes deployment processes easier, guarantees high availability, and makes it easier to use resources efficiently. It is great for handling microservices at scale because it has features like load balancing, service discovery, and rolling updates.
