Possible disadvantages of Fly.io

Learning Curve
New users may find the platform's concepts and deployment methods unfamiliar, requiring time to learn.
Documentation
Users have reported that the documentation can sometimes be lacking in detail or difficult to navigate.
Cost
While Fly.io offers a free tier, the cost can become significant as you scale your applications.
Limited Language Support
Fly.io supports fewer runtime environments and languages compared to more established platforms like AWS or Azure.
Platform Maturity
As a relatively new platform, Fly.io may lack some advanced features and ecosystem integrations offered by more mature competitors.
Debugging
The debugging tools and processes can be less comprehensive compared to traditional cloud providers.

Node.js features and specs

Asynchronous and Event-Driven
Node.js uses an asynchronous, non-blocking, and event-driven I/O model, making it efficient and scalable for handling multiple simultaneous connections.
JavaScript Everywhere
Developers can use JavaScript for both client-side and server-side programming, providing a unified language environment and better synergy between front-end and back-end development.
Large Community and NPM
Node.js has a vibrant community and a rich ecosystem with the Node Package Manager (NPM), which offers thousands of open-source libraries and tools that can be integrated easily into projects.
High Performance
Built on the V8 JavaScript engine from Google, Node.js translates JavaScript directly into native machine code, which increases performance and speed.
Scalability
Designed with microservices and scalability in mind, Node.js enables easy horizontal scaling across multiple servers.
JSON Support
Node.js seamlessly handles JSON, which is a common format for API responses, making it an excellent choice for building RESTful APIs and data-intensive real-time applications.

Possible disadvantages of Node.js

Callback Hell
The reliance on callbacks to manage asynchronous operations can lead to deeply nested and difficult-to-read code, commonly referred to as 'Callback Hell'.
Not Suitable for CPU-Intensive Tasks
Node.js is optimized for I/O operations and can become inefficient for CPU-intensive tasks, slowing down overall performance due to its single-threaded event loop.
Immaturity of Tools
Compared to more established technologies, some Node.js libraries and tools still lack maturity and comprehensive documentation, which can be challenging for developers.
Callback and Promise Overheads
Managing asynchronous operations using callbacks or promises can lead to additional complexity and overhead, impacting maintainability and performance if not handled correctly.
Fragmented Ecosystem
The fast-paced evolution of Node.js and its ecosystem can lead to fragmentation, with numerous versions and libraries that may not always be compatible with each other.
Security Issues
The extensive use of third-party libraries via NPM can introduce security vulnerabilities if not properly managed and updated, making applications more susceptible to attacks.

Object Storage & CDN Journey
Tigris (Fly.io) provides globally distributed, S3-compatible storage with low latency, addressing the B2 latency limitations. However, its pricing model includes per-request charges in addition to storage. For an API-heavy workload like a chat system, this would scale poorly, so I decided not to go with it. - Source: dev.to / 3 months ago
