Monolith vs. Microservices: Choosing the Right Architecture

🏛️Monolith architectures are not limited to a single machine and can be horizontally scaled.

🔬Microservices are not necessarily tiny machines, but rather separate business units with specific functions and data.

⚖️Monoliths are suitable for small cohesive teams, while microservices are scalable and allow parallel development.

🔄Monolith deployments are simpler due to identical codebases, while microservices require careful coordination and monitoring.

⚠️Monoliths can be challenging to onboard new team members and may have a higher risk of system failures.

Are monolith architectures limited to single machines?

—No, monoliths can be horizontally scaled across multiple machines.

Are microservices tiny machines that always interact with each other?

—No, microservices are separate business units with specific functions and databases.

When should I choose a monolith architecture?

—Monoliths are suitable for small cohesive teams and projects with less complexity and time constraints.

What are the advantages of monolith architectures?

—Monoliths are easier to develop, deploy, and maintain. They have fewer moving parts and faster performance.

What are the disadvantages of microservices?

—Microservices require careful design, coordination, and monitoring. They can lead to more complex deployments and increased risk of partial system failures.

00:00The video discusses the choice between monolith and microservices architectures.

02:14Monolith architectures can be horizontally scaled and are suitable for small teams with cohesive dynamics.

05:35Microservices offer better scalability and parallel development, but require careful design.

07:23In system design interviews, microservices are often preferred for larger systems due to their advantages.

07:50Successful systems like Stack Overflow use the monolith architecture, while companies like Google and Facebook extensively use microservices.
