Discussion

#InterSystems Business Solutions and Architectures #Caché #InterSystems IRIS

I'm working with clients planning migrate from Caché to IRIS and I want to summary advantages to go to IRIS. I think is:

IntegratedML - AutoML - Agile machine learning
IAM - InterSystems API Manager
Interoperability
Advanced Reports (JReport)
Cloud Manager/Docker and DevOps support
ZPM - Package manager
Native API - Node.js, Python, Java and .NET interoperability
Core based license x user based license
InterSystems Support and new features
Improved management and monitoring features

Can you help me to think or detail these 10 topics?

What happens to old code as
- all kind of $ZU() funktions ? Some well documented, some poor, some not
- self written System Commands and Functions ?
Rewrite it ? or are they the same for Iris ?
Documentation that I found was not so detailed. Any article available ?

Great list. Even higher performance and greater scalability.

Analytics (aka DeppSee) build it.

also... great advantage for Intersystems itself (to earn more for license upgrade).

Hi @Yuri Marx,

at the very first topic, I will put at the top of your list :

0. better performances

It can be seen as obvious, but IRIS is **really** faster than Caché.

Hi Sylvain,

Is it possible to publish more details of the scenario which showed such impressive figures?

Hi @Yuri Marx,

and today, you can add to this list :

Embedded Python
Adaptive Analytics (AtScale)
System Alerting and Monitoring (SAM)
InterSystems Kubernetes Operator (IKO)
SQL improvements on performances and capabilities (Global Iterator, Columnar Storage, Adaptive Parallel Execution, LOAD DATA, etc.)
Kernel enhancements (Mirroring, etc.)
Security enhancements
etc. (see release notes)

What is Global Iterator?

What about
- enhanced multi model capabilities via native json storage / document database
- in-memory bi-directional java and .net gateway (and python but have embedded python since then)
- AWS Cloud connectors
- REST enhancements (API publishing via swagger, spec first development from OpenAPI 2 spec)

Also, more generally, IRIS is the successor of Ensemble + iknow + DeepSee, rather than just Caché
