Hosney Osman - PeerSpot reviewer
Technical Solution Architect at Vodafone
Real-time analytics have transformed response times and support huge data volumes with compression
I do not have any comment related to the improvement of the solution; for sure, it needs improvement, but for my use cases, it is very sufficient, and I think for the biggest companies, it needs a very powerful infrastructure. The area where improvement is required the most in the product is the UI. The problem with the UI is that it is not complex for understanding, but it needs some training to know what each button does, how it works, and the many variables needed.

Rapid deployment has simplified backend work and supports independent database management
We did not use the replication or inbuilt replication from Oracle Java DB. We have separate core functions to replicate the database and migrate the database. We are not using the inbuilt encryption of Oracle Java DB. We are using encryptions such as AES. We are currently using these to encrypt the sensitive data. We encrypt not only passwords but mostly all the data.

Cons
