Reliable cloud service enhances ERP management with advanced security features
I use Amazon AWS for ERP implementation. My responsibility is to integrate our application into the AWS cloud and provide AI solutions to the infrastructure AWS is stable and has provided a reliable infrastructure for my organization. AWS offers add-on services such as security and automated…

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 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."
"Amazon AWS has many merits, in terms of scalability, stability, and availability. I have loved using this tool."
"They provide cutting-edge features compared to other cloud vendors."
"It is easy to spin up resources."
"The tool is a hosting platform that we can leverage to open servers. We can use it to build databases. We use cost management and high-performance capabilities of the tool."
"One of the features offered is scalability on demand."
"The compute and the elasticness of the compute is really great. Whenever there's a load, it automatically adds the servers and then reduces the servers based on the configuration. This is really wonderful, more cost-effective, and it's been really good for us."
"Easy to deploy through the channel model for serverless architecture and easy to integrate through the organization model."
"For non-complex applications, the IBM Cloud works fine and the price is much lower than the competitors."
"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 is a scalable product. You can scale it up and down."
"What I like most in IBM Public Cloud is how easy it is to create serverless functions. They are called IBM functions, but in AWS, they are called Lambda functions. Those are pretty standard, and another thing I like the most is that you have fewer restrictions on the amount of data you can transfer across those functions. IBM Public Cloud is way more flexible than AWS. I also like that IBM Public Cloud is pretty straightforward to integrate. As long as you have all the tools IBM provides you, getting everything up and running is straightforward."
"The initial setup was very easy. It's quite straightforward. Deployment took about fifteen minutes. Everything is well organized."
"This is a predictable and dependable service."
"It provides robust analytics and management tools to give customers complete visibility into their environment and infrastructure."
"I am very much satisfied with the technical support team at IBM Public Cloud."
 

Cons

"AWS support could be better."
"The difficulty of the implementation depends on the project. We have a lot of very complicated and complex project which make the implementation more difficult. However, a small project can be very simple to implement. In general, over 90% of the project tend to be complex implementations."
"Some services which were easy to use through shortcuts are now more complicated to use."
"Amazon tools are for more mature DevOps. The process and the Dev is very good, but it doesn't compare to the ease of using the Google Cloud Platform."
"There is room for improvement in pricing."
"They do not yet have a complete solution for APM monitoring. But this, along with real user monitoring, is something that they are actively working on improving."
"When I try to enter the multi-cloud, they provide very poor support. Support is a concern with Amazon."
"Amazon AWS would be improved if it were more stable and if customer support's responses were faster."
"The connectivity and speed of IBM Public Cloud are much lower compared to the competition."
"I would like to see a more user-friendly deployment process in the next release of this solution."
"They could improve on customizing reporting capabilities."
"It could be more secure."
"It will be challenging to implement if you do not have any experience."
"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’s pricing could be improved."
"There is not a lot of support for this solution, which is something that needs to be improved."
 

Pricing and Cost Advice

"It is very expensive, you have to be very cautious."
"If I was going to compare the cost of Amazon AWS to Microsoft Azure, they are approximately the same."
"It is not the cheapest one, but there is a good ratio between the quality of service and the pricing. Its price is good for me."
"AWS is expensive and the cost should be reduced."
"It's pay-as-you-go... but I think the pricing becomes a problem as the IT organization grows. They need to give better pricing when companies grow."
"Some customers will provide their own license and others will purchase it directly from AWS."
"Licensing can be purchased on a yearly basis, which is an auto-renewal. We also have an on-demand on-pay purchase."
"It's expensive."
"Pricing is not as fair as Amazon or Azure."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a nine out of ten."
"We are using the trial version of this solution, so we have not paid anything."
"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."
"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."
"The price of IBM Cloud is very cheap compared to competitors AWS and Azure."

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.
