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.
Nicolas Chabrier - PeerSpot reviewer
Promotes clear, logical structures preventing impractical configurations and offers seamless integration
The only thing is regarding the management of multi-cloud environments. That's not really possible. So basically, it's wonderful if you manage Microsoft clearly and if you manage Microsoft Azure, but if you need to consume external services and have a global overview of all your consumption, it's not the case. Google, for instance, has tools that help you manage multiple environments, which makes sense because Google is really the cloud provider. So that's why they need to be compliant with the others. But for sure, Microsoft's approach is different, and it's wonderful when you're one hundred percent on Azure. But if you'd like to have something more of a multi-cloud strategy, that's a bit of a gap where they could improve.

Quotes from Members

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

Pros

"Their technical support is really good. I am very satisfied."
"The reason I like AWS is that they have a large market share and a large presence. When it comes to our use case, a big positive is that MuleSoft and AWS are working together very well. So instead of competing against each other, they're meshing together."
"We deploy our core application and our integration platform on AWS EC2 instances. These applications contain multiple containerized Python Django applications, which need to scale up and down dynamically."
"The most valuable feature of the solution is that they offer everything around in just one platform."
"AWS is easy to manage."
"The technical support is good."
"As a service vendor, we have helped clients to achieve faster "go to market" on their products, and have provided highly flexible cost-effective system management solutions."
"It's very stable and the performance is good."
"I've found the stability to be excellent. The performance is good."
"There is no installation for this product because it is a cloud product."
"This product is very good because it is accessible in remote locations, and anyone can deploy from any place."
"The availability is second to none. Customer support is very good."
"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."
"I am very much satisfied with the technical support team at IBM Public Cloud."
"For non-complex applications, the IBM Cloud works fine and the price is much lower than the competitors."
"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."
"My experience with technical support so far is very good."
"The solution's technical support was very good."
"The valuable features of Microsoft Azure are that it is cloud-based and has good storage. The storage is completely managed by Azure. We do not need to do any patching of security because it is handled by Azure which is a benefit. The solution is fully compatible with the Microsoft technology stack and is very scalable."
"The robust encryption services increase the confidence of tech users."
"Microsoft Azure has thousands of services and products."
"It is stable and collaborative."
"Some features of Azure are very important for us. You can control access for your company, it's not complicated managing the solution either. I think the solution is very stable, secure and the documentation Microsoft has on their website is complete. You can use it to find the solution's problems or implement solutions."
"The product is highly stable."
 

Cons

"I also use Google Cloud GCP and AWS cannot directly use the Azure EC2 consult. They could add that feature. Direct connection to the EC2 console server would be very useful."
"The response time of technical support could be better."
"I generally don't like the user experience of Amazon. It's not the best."
"The pricing could be adjusted to provide more advantages versus current on-premise solutions for business applications."
"I'd love to see an Amazon data center here in Peru."
"They are mainly generalists without access to the operating system. As such, they can provide container level insights,not necessarily at the application level."
"The product should reduce carbon emissions."
"An integrated platform would make it easier for administrators to monitor and manage."
"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."
"The initial setup and the pricing are areas that need improvement."
"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."
"It will be challenging to implement if you do not have any experience."
"The product should offer more computing, similar to Amazon."
"It could be more secure."
"There is not a lot of support for this solution, which is something that needs to be improved."
"Recently, we just faced some issues with the operating system due to the end of life of CentOS 6...So, then the client wanted to try it out under AWS instead of IBM. In short, it has some complexities."
"The solution could improve by being more user-friendly."
"Auto ML could be improved technically."
"If the price were reduced then it would be an improvement."
"Pricing is high if you plan to use it on a larger scale."
"Integration with more platforms needs improvement."
"I would prefer Microsoft Azure to increase the free trial, then developers can take advantage, and it could increase their sales."
"The cost of the product is too high. It would be ideal if they could lower it a bit for their customers."
"There is room for improvement in the pricing structure, user interface design (UI/UX), clear navigation, and documentation support of Microsoft Azure."
 

Pricing and Cost Advice

"Licensing can be purchased on a yearly basis, which is an auto-renewal. We also have an on-demand on-pay purchase."
"Some customers will provide their own license and others will purchase it directly from AWS."
"When compared to GCP, Google, or Azure, the price could be lower."
"AWS is not an expensive product."
"The prices are somewhat on the higher side. It would help if they can bring it down, especially for the sporting segment and for on-demand instances."
"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."
"AWS is expensive and the cost should be reduced."
"If you can plan capacity for one or three years, you can use the upfront payment option which allows you to save up to 50%."
"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."
"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."
"IBM has a lesser price compared to other cloud service providers like Azure and AWS."
"The licensing fees are straightforward and predictable."
"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."
"We are using the trial version of this solution, so we have not paid anything."
"It pretty much has a standard price. There is no hidden price with IBM Public Cloud."
"We're paying in dollars, and it's very expensive for us because of the exchange rates."
"Microsoft Azure is more expensive than other solutions, such as GCP. We have found that GCP offers more utilities at a very reasonable price."
"The licensing price is fine."
"It is similar to AWS, where it is on-demand and is billed monthly."
"It is paid on a per-use basis."
"Azure costing can be multi-layered."
"The licensing fees are more than $1,000,000 USD annually."
"The pricing of Microsoft Azure is not very flexible."
