What are some effective scaling strategies for a Node.js application?

There are several strategies you can use to scale a Node.js application, including horizontal scaling, vertical scaling, and using load balancers. Would you like to dive deeper into any specific strategy?

Can you explain horizontal scaling?

Horizontal scaling involves adding more machines or instances to handle increased load. This can be achieved using cloud services like AWS or Azure, where you can spin up additional instances of your application.

What about vertical scaling?

Vertical scaling means upgrading the existing server's resources, such as CPU, RAM, or storage. While it's simpler, it has limits and can lead to downtime during upgrades.

How do load balancers fit into this?

Load balancers distribute incoming traffic across multiple servers, ensuring no single server becomes overwhelmed. This is crucial for maintaining performance as your application scales.
