Amazon SNS vs Nexmo: What are the differences?

Amazon SNS: Fully managed push messaging service. Amazon Simple Notification Service makes it simple and cost-effective to push to mobile devices such as iPhone, iPad, Android, Kindle Fire, and internet connected smart devices, as well as pushing to other distributed services. Besides pushing cloud notifications directly to mobile devices, SNS can also deliver notifications by SMS text message or email, to Simple Queue Service (SQS) queues, or to any HTTP endpoint; Nexmo: API for SMS, Voice and Phone Verification. Nexmo connects your apps directly to carriers around the world. Integrate SMS and Voice messages using one simple API. Use Nexmo Verity to register users, verify transactions, and implement two factor authentication.

Amazon SNS and Nexmo are primarily classified as "Mobile Push Messaging" and "Voice and SMS" tools respectively.

Some of the features offered by Amazon SNS are:

  • In most cases, developers can get started with Amazon SNS by using just three APIs: CreateTopic, Subscribe, and Publish. Additional APIs are available, which provide more advanced functionality.
  • With SNS you can publish a message once, and deliver it one or more times. So you can choose to direct unique messages to individual Apple, Google or Amazon devices, or broadcast deliveries to many mobile devices with a single publish request.
  • SNS allows you to group multiple recipients using topics. A topic is an “access point” for allowing recipients to dynamically subscribe for identical copies of the same notification. One topic can support deliveries to multiple endpoint types -- for example, you can group together iOS, Android and SMS recipients. When you publish once to a topic, SNS delivers appropriately formatted copies of your message to each subscriber.

On the other hand, Nexmo provides the following key features:

  • Inbound SMS
  • Outbound SMS
  • Outbound Text-To-Speech Calls

According to the StackShare community, Amazon SNS has a broader approval, being mentioned in 230 company stacks & 78 developers stacks; compared to Nexmo, which is listed in 27 company stacks and 11 developer stacks.

      Nexmo vs Twilio ?

      Back in the early days at SmartZip Analytics, that evaluation had - for whatever reason - been made by Product Management. Some developers might have been consulted, but we hadn't made the final call and some key engineering aspects of it were omitted.

      When revamping the platform, I made sure to flip the decision process how it should be. Business provided an input but Engineering lead the way and has the final say on all implementation matters. My engineers and I decided on re-evaluating the criteria and vendor selection. Not only did we need SMS support, but were we not thinking about #VoiceAndSms support as the use cases evolved.

      Also, on an engineering standpoint, SDK mattered. Nexmo didn't have any. Twilio did. No-one would ever want to re-build from scratch integration layers vendors should naturally come up with and provide their customers with.

      Twilio won on all fronts. Including costs and implementation timelines. No-one even noticed the vendor switch.

      Many years later, Twilio demonstrated its position as a leader by holding conferences in the Bay Area, announcing features like Twilio Functions. Even acquired Authy which we also used for 2FA. Twilio's growth has been amazing. Its recent acquisition of SendGrid continues to show it.

      It just works as expected within minutes -- you get both outbound/inbound messages, with delivery receipts or incoming callbacks -- all working in the easiest form.

      We fall back to Nexmo when Chikka (https://api.chikka.com) and Semaphore (http://semaphore.co) have downtime or deliverability problems. Chikka and Semaphore are local (Philippine) SMS APIs handled by SMART and Globe, respectively, and report higher deliverability rates than Nexmo (at lower cost).

      Our primary transport mechanism for events. One SNS topic carries a specific event type and n-number of subscribers (usually a Lambda) may subscribe to that event.

      We use SNS for platform-agnostic mobile push message handling, essentially to avoid dealing with APNS ourselves.

      SNS is at the core of our messaging - we use the fan out pattern.
