| Quality of Service | |||
Scalability | Scalability is vital as it ensures the service can handle increased data load or users without compromising performance. | Amazon SQS No published metrics are available. | Socket.IO No published metrics. Socket.IO servers don’t communicate between them, so you need a way to route events to all clients, even if they are connected to different servers. This is made possible by using adapters, of which the Redis adapter seems to be the most popular choice. |
Guaranteed message delivery | Ensures messages are never lost during transmission, even in the presence of network disruptions. | Amazon SQS Yes AWS SQS provides robust support for guaranteed message delivery, ensuring that each message is reliably delivered to its intended recipient. | Socket.IO Partial By default, Socket.IO provides an "at most once" guarantee of delivery. From the client side, you can achieve an at least once guarantee with acknowledgements and timeouts. |
Guaranteed message ordering | Maintains the sequence of messages as they were sent. This is particularly important in apps where the chronological order of messages is essential for meaningful communication. | Amazon SQS Yes For AWS SQS FIFO Queues, messages are delivered in the exact order they are sent, following a strict First-In-First-Out (FIFO) sequence. | Socket.IO |
Exactly-once message delivery | Guarantees that each message is processed exactly once, preventing data inconsistencies that can arise from duplicate processing or missing messages. | Amazon SQS Yes When using AWS SQS FIFO Queues, messages are delivered exactly once with no duplication. | Socket.IO No At least once or at most once only. |
| Performance & availability | |||
Uptime Guarantee | An uptime guarantee instills confidence in the reliability of the service and protects your business from the negative impacts of downtime. | Amazon SQS 99.9%. Read more | Socket.IO No It is a library, not a platform. |
Global edge network | By bringing servers (Points of Presence, or PoP) geographically closer to the devices of end users, and routing requests to the nearest PoP, global latency is reduced to a minimum. | Amazon SQS Yes | Socket.IO No |
Multi-region data replication (message durability) | By replicating data across multiple regions, the risk of data loss or downtime is greatly mitigated since if data is lost or a server fails in one region, the information can be retrieved from another. | Amazon SQS Partial AWS SQS provides high message durability within a single AWS region by replicating messages across multiple Availability Zones. But it does not natively support cross-region replication. For multi-region data replication, you can use additional strategies, such as using AWS services like AWS Lambda or AWS Data Pipeline to replicate messages from SQS queues in one region to SQS queues in another region. | Socket.IO No |
No single point of failure or congestion | Having no single point of failure means a system is resilient and can continue to operate even if one part fails. Avoiding a single point of congestion ensures messages flow efficiently across the system and avoids bottlenecks that could lead to performance issues under load. | Amazon SQS Yes Messages in AWS SQS are distributed across various availability zones in a region, ensuring high availability and scalability. | Socket.IO No As Socket.IO is a library, the implementation of it dictates points of failure and congestion. |
Latency | Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience. | Amazon SQS Latencies for SendMessage, ReceiveMessage, and DeleteMessage API requests range from tens to low hundreds of milliseconds. | Socket.IO Unknown |
| Security & compliance | |||
API key authentication | Simplifies the authentication code on trusted servers compared to requesting, managing, and refreshing tokens. | Amazon SQS Yes | Socket.IO No |
