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

Pusher

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.

Pusher

No

Pusher apps are located in a single data center rather than distributed across multiple data centers. Any latency issues that occur in that data center will affect all apps hosted there.

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.

Pusher

No

Pusher apps are located in a single data center rather than distributed across multiple data centers. If that data center goes offline then all apps hosted there are affected.

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.

Pusher

Not shared. Because apps exist in only one region, message latencies increase for clients the further they are from your chosen data center.

Security & compliance
API key authentication

Simplifies the authentication code on trusted servers compared to requesting, managing, and refreshing tokens.

Amazon SQS

Yes

Pusher

Yes

Token-based authentication

Provides a means to securely authenticate user devices against your user management system.

Amazon SQS

No

AWS SQS does not directly support token-based authentication. Instead, AWS SQS relies on AWS Identity and Access Management (IAM) for authentication and authorization.

Pusher

Yes

Single Sign-On (SSO) authentication

SSO streamlines login processes, boosts security by minimizing password use, and meets compliance needs for secure data access management.

Amazon SQS

Yes

Pusher

Partial

For GitHub and Google.

Rules for permissions and operations

Provides control over which users can subscribe and publish to certain channels.

Amazon SQS

Yes

Pusher

Partial

Requires you to implement an endpoint they will call to check if operation is allowed.

End-to-end encryption

Ensures that the data transmitted between the client and the API server remains confidential and secure while in transit.

Amazon SQS

Yes

Pusher

Yes

Encryption at rest

Ensures data stored by the service is secure and compliant, while also mitigating the risks of a data breach.

Amazon SQS

Yes

AWS SQS supports encryption at rest using AWS KMS (Key Management Service).

Pusher

No

Compliance

Compliance with regulations can impact your ability to meet legal obligations in your industry.

Amazon SQS
  • PCI DSS Level 1 certified
  • HIPAA-eligible
Pusher
  • GDPR compliant
