Managed cloud services have helped accelerate experiments with flexible configuration options
Sometimes the costs associated with spinning up a service, especially managed services, have implications. For example, if I create a Glue job, that will create S3 buckets and other resources that have cost implications, but once I clean up a Glue job, it does not delete the other accessory resources. Sometimes, I have to go hunting for what resources Amazon AWS might have provisioned and how it is costing behind the scenes. It can be complex depending on your level of expertise. It is not as easy to get started, especially when it comes to secure practices. Amazon AWS is more hands-on than other platforms.

Affordability and security improve our cloud experience while learning new systems
I'm not working with any AI features in IBM Public Cloud, but they are in the process of building it.I am very satisfied with the security that IBM Public Cloud provides. I would rate IBM Public Cloud eight out of ten, where one is worst and ten is the best.

Quotes from Members

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

Pros

"The solution also helps organizations to move applications to a containerized platform."
"We can easily upgrade and downgrade the Instance."
"This solution is stable and reliable."
"We write a lot of Lambda functions for various services, as well as serverless functions."
"They provide cutting-edge features compared to other cloud vendors."
"The price forecasting and billing dashboard by service, with billing budgets and alerts, have helped us shut down resources that were accruing costs that we no longer needed, saving us money."
"We pretty much like everything and we are excited about the seamless capability the EC2 service is offering."
"Easy to deploy through the channel model for serverless architecture and easy to integrate through the organization model."
"The beauty of cloud service providers, especially public cloud service providers, is that they are scalable every time when you need them because their payment model is pay-as-you-go."
"This is a predictable and dependable service."
"There is no installation for this product because it is a cloud product."
"The price of IBM Cloud is most valuable for us. The service is personable and gives us a good rapport. I can't say it's the best, but it was enough for our needs."
"It's straightforward, has a good environment and is cost-effective."
"It is a scalable product. You can scale it up and down."
"It provides robust analytics and management tools to give customers complete visibility into their environment and infrastructure."
"For non-complex applications, the IBM Cloud works fine and the price is much lower than the competitors."
 

Cons

"Recently we had a long conversation about functionality that is missing in Alexa — in Mexico, specifically. Alexa for Business is a service and platform that Americans can use to make a call to an Amazon Echo device or a telephone via the app. But in Mexico, we are not allowed to use that technology. This is a significant disadvantage of AWS for those living in Mexico."
"In a future release, I would like to see more support for AI because it is the future."
"Amazon AWS is a very poor product for students. Microsoft Azure is a better solution."
"Could be more user friendly and include additional applications."
"Amazon AWS could improve by being more secure and adding more features."
"There are plenty of areas for improvement. For example, the ease of tagging could be improved. The tool could integrate AI tools to identify better and manage costs. Calculating the cost of some services could be more straightforward."
"Requires better integration with other cloud products."
"The features that should be improved are that there should be better clarity on their invoicing. There are so many things they charge for - high line items in the invoice. I think there should be more clarity and more ease of use with their billing. I'd like to see better ease of use of with the billing console and a clear dashboard to understand the usage."
"The connectivity and speed of IBM Public Cloud are much lower compared to the competition."
"The initial setup and the pricing are areas that need improvement."
"Normally, for any cloud, we get a lot of information on the web, but that is missing in the case of IBM Public Cloud. We need some technical support documents. That is the only thing missing in IBM Public Cloud."
"An area for improvement in IBM Public Cloud is getting up-to-date information on how to set up everything. It's hard to find new documentation."
"They do not have a very good virtual network implemented, and the VPC is the most important feature that needs to be improved."
"Maybe performance enhancers and reports could be better improved. If they do so, it would be better. Of all the drawbacks I saw, this would be the biggest enhancement."
"While they have about 99% of what we need, the only exception, perhaps, was the push notification feature that was discontinued. They delayed the replacement product."
"The solution needs to be more autonomous. It should let the DL go to allow for more jobs on the cloud. It could have a better interface as well."
 

Pricing and Cost Advice

"The pricing of AWS was attractive for us, so that's something that's okay at least for this transaction-based system. However, we still have some concerns about more data-driven applications or those that involve a lot of heavy uploading and downloading. So our whole data warehouse is still something that would not go into the cloud because of the pricing model."
"It's not very pricey, but it could be cheaper."
"I find that Amazon AWS is expensive."
"One of the best thing in Amazon AWS is you are billed for the service you use."
"We have a monthly subscription for Amazon AWS."
"The cost is on a monthly basis."
"The price can be better."
"It's an expensive product."
"It pretty much has a standard price. There is no hidden price with IBM Public Cloud."
"IBM has a lesser price compared to other cloud service providers like Azure and AWS."
"IBM Public Cloud is pretty cheap. They have an ongoing free tier that basically won't expire, so as long as your solution is small enough, you can have a test set that you can use for demos, which will cost you almost nothing."
"The price of IBM Cloud is very cheap compared to competitors AWS and Azure."
"Pricing is not as fair as Amazon or Azure."
"In order to be competitive, you have to commit to a contract for at least one year, but you pay a fixed monthly fee."
"The licensing fees are straightforward and predictable."
"We are using the trial version of this solution, so we have not paid anything."

I agree with Vik and Marcelo. AWS cloud is more matured, but you would like to run some specific IBM business tools like document management, IBM Watson for AI, SPSS analytics then IBM Cloud should be preferred.

Amazon AWS is superior to IBM public for several reasons.  The most important reason is the diversity of software tools, the geographic diversity and availability, lower operating costs and excellent customer service. All cloud companies are simply playing catch-up to AWS.
