Faced timeouts and complexity but have automated Python data processing in the cloud
Elastic Pool is basically a SQL server that can host multiple SQL databases, not Azure Elastic SAN or just Elastic. Elastic Pool has nothing to do with the ELK stack. A Storage Account is called the file storage, and it is like an S3 from Azure. The file storage is indeed called a Storage Account. I am not actively working on Active Directory or any solutions like App Logic from Azure. I am not using ML Studio or Data Box. For pricing, I would say it is also a bit more expensive than normal, and I would rate it four as well. I would give this review an overall rating of four out of ten.

Quick to deploy but being deprecated by IBM and should be merged with Kubernetes
We enjoy the fast deployment. Cloud Foundry builds the runtime environment directly without requiring dependency management from the developer or administrator. The autoscaling is great. It is just a switch that needs to be turned on, and autoscaling starts working. At this moment, you begin to see different meters about usage that helps you in updating the scaling limits, which help you tune the running instances. Besides this, autoscaling can be scheduled, so in times of low activity, you can have lower limits or increase in advance for special dates. It has good logging. CF has logging events that help identify when a transaction runs and its response time which helps in monitoring execution.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Azure Functions has a quite easy and straightforward initial setup."
"My favorite component of IBM's solution is Node-RED, which greatly shortens the amount of time required to develop, test, and deploy new applications."
"Cloud Foundry builds the runtime environment directly without requiring dependency management from the user."
"IBM is the only vendor to offer integration with blockchain for smart contract development."
"By moving to IBM Cloud Foundry, we reduced our project time by a factor of two and decreased costs by a factor of four because it was a PoC."
 

Cons

"Microsoft can improve Azure Functions by adding durable functions, as the current setup times out after thirty minutes, which is quite irritating."
"After the initial excitement period with Node-RED is over, you crave the need of additional integrations to third-party services."
"After the initial excitement period with Node-RED is over, you crave the need of additional integrations to third-party services."
"In IBM Cloud, the product has been deprecated in favor of Kubernetes, which is a more complicated infrastructure to manage."
 

Pricing and Cost Advice

Information not available
"IBM has a free tier and payment option depending on the products selected."
"The pricing models should be reworked to the needs of a wider range of companies. Some customers will not be able to afford it until quite a few years into production, even after good PoC results and a successful launch."
"You are allocated a minimum amount of resources in the free tier. This seems fair and highly scalable, as you pay per usage as per cloud pricing schemes."
