Amazon Cognito vs BlazeMeter: What are the differences?
Developers describe Amazon Cognito as "Securely manage and synchronize app data for your users across their mobile devices". You can create unique identities for your users through a number of public login providers (Amazon, Facebook, and Google) and also support unauthenticated guests. You can save app data locally on users’ devices allowing your applications to work even when the devices are offline. On the other hand, BlazeMeter is detailed as "The Load Testing Platform for Developers". Simulate any user scenario for webapps, websites, mobile apps or web services. 100% Apache JMeter compatible. Scalable from 1 to 1,000,000+ concurrent users.
.
Amazon Cognito can be classified as a tool in the "User Management and Authentication" category, while BlazeMeter is grouped under "Load and Performance Testing".
Some of the features offered by Amazon Cognito are:
- Manage Unique Identities
- Work Offline
- Store and Sync across Devices
On the other hand, BlazeMeter provides the following key features:
- 100% JMeter Compatible- Take full advantage of JMeter’s scripting capabilities or let our auto-scripting feature take care of the details.
- Scalable and Realistic- Easily scale from 100 to 300,000+ concurrent users using realistic visitor behaviour and browser simulation.
- Start Testing in 2 Minutes- Use up to 100 dedicated servers per test. No setup or installation required. Self-service and on-demand.
"Backed by Amazon" is the primary reason why developers consider Amazon Cognito over the competitors, whereas "I can run load tests without needing JMeter scripts. " was stated as the key factor in picking BlazeMeter.
According to the StackShare community, Amazon Cognito has a broader approval, being mentioned in 41 company stacks & 13 developers stacks; compared to BlazeMeter, which is listed in 6 company stacks and 3 developer stacks.
I started our team on Amazon Cognito because I was a Solutions Architect at AWS and found it really easy to follow the tutorials and get a basic app up and running with it.
When our team started working with it, they very quickly became frustrated because of the poor documentation. After 4 days of trying to get all the basic passwordless auth working, our lead engineer made the decision to abandon it and try Auth0... and managed to get everything implemented in 4 hours.
The consensus was that Cognito just isn't mature enough or well-documented, and that the implementation does not cater for real world use cases the way that it should. I believe Amplify has made some of this simpler, but I would still recommend Auth0 as it's been bulletproof for us, and is a sensible price.
