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…

Has a quick development cycle and continuous integration
The initial setup is straightforward. Heroku integrates well. You only have to push the code, and it automatically deploys the new version. Whether you have permission depends on the application. Currently, I have one application that I deploy myself. I rate the initial setup a nine out of ten, where one is difficult and ten is easy.
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

"I like that is very easy to use and that it's flexible."
"Our primary use case is to use the solution for running many relatively small instances for back office applications and various other business important applications."
"Elasticity has always been AWS's mandate. The flexibility of their platform from a systems perspective lives up to its claims."
"It is easy to use."
"AWS is constantly growing in features with every new version. It's a good cloud provider with excellent availability. The integration is good, and their security products are interesting. Amazon is always innovating and delivering new products to customers."
"The technical support is good."
"We pretty much like everything and we are excited about the seamless capability the EC2 service is offering."
"The AWS feature that I most enjoy is Lambda functions. I primarily use serverless components because they allow you to process things without having to compromise on resources like when running EC2 instances or virtual machines. With minimal effort, you can scale up an unlimited number of processes, even concurrently, to process things. I frequently work with web APIs, so I use Lambda a lot in this area."
"One of the best things about Heroku is that it is very easy and straightforward to deploy an application."
"It's easy to push a change and to deploy new things."
"Thanks to Heroku, we don't need to do as much direct management in AWS."
"What I found most valuable about this solution is that it's easy to use and integrate with GitHub actions."
"The product is stable."
"It is easy to deploy applications, and we don't need to bother about software updates on the server. We don't need to bother about machines, servers, and hardware. We only need to care about the system and functionality that we need or want to develop. They take care of everything else. It provides high availability. It is a pretty good solution that provides everything that we need. It has everything that we need to run our applications. We have many different applications, and we generate three million bills for a company in Brazil. We see more than a billion requests per day in another application. Everything works just fine, and it is very good."
"Valuable for us was the fast deployment. This means the time to market is improved without pain for developers."
"The most valuable feature of Heroku is the continuous integration and applications it provides."
"It is a reliable solution that is easy to set up."
"Microsoft Azure supports our company growth through its robust features."
"The most valuable features of Azure for me are its ease of management, recoverable virtual machines with backup support, excellent customer support, and user-friendly interface."
"Microsoft Azure is a very dynamic cloud service that allows you to migrate your workload, applications, and data."
"Managed storage capabilities, which create a very simple way to create, copy, and replicate local or geo-replicate, it's very simple to assign workloads."
"It is a scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"The solution provides multiple well integrated services which happen to work together seamlessly and provide flexibility and scalability for use cases all around the industry."
"In Azure, everything is pretty straightforward. Once you know it, the platform is very easy to use."
 

Cons

"Amazon AWS could improve by being more secure and adding more features."
"We have had some difficulty figuring out how to monitor how many EC2 instances have been networked into our entire enterprise. We usually try to create a diagram outside of AWS. The types of information we are trying to determine are, for example, what hardware devices are interconnected, and when was the interconnection made."
"They should implement the command shell by default. As it is now, to open the console, you have to download the command application."
"You'll probably experience some sticker shock with AWS. You attempt to understand the cost, but you don't realize what you're paying until you get your first bill. I don't know if Amazon does that on purpose, but costs can get out of control quickly if you don't have someone who specializes in AWS cost management."
"The product should reduce carbon emissions."
"Our API Management solution is integrated with Lambda, and last year, we had an issue while upgrading Lambda from version 8.0 to version 10. It seemed like Lambda runtime was changed by AWS, and there was a bug that caused the downtime. The loading of the dashboard is slow. It could be because I am located in China."
"The overall convenience and the ease to use could be improved."
"Support response times can be improved, especially in areas where faster assistance is crucial."
"Heroku should increase its slug size limits."
"We have to do daily restarts of some processes, which is annoying, and the support for custom CI could be better."
"Heroku had an authentication problem a few months ago, but they solved it."
"Heroku doesn't support Docker images on the CI infrastructure."
"Their support is good, but they can improve their response time."
"The pricing could be improved because scaling the database becomes costly."
"We would like to be notified when something goes wrong in the process. When something is not working, we should get an alert."
"I think this solution would be improved if free demos were available indefinitely."
"Support could be improved. If you pay for a higher plan, it's okay, however, the lower plans don't offer as good of a service experience."
"Improving transparency in billing is crucial for us. Understanding how billing works only becomes clear once we start using the services. A more accurate billing calculator would help us anticipate costs associated with using specific services."
"Microsoft Azure needs to improve its user interface. New developers and teams have difficulty understanding its lifecycle."
"We need more customization and support for doing so."
"Azure does not handle scalability as well as its competitors. Sometimes a 10 percent increase in a server with 20 percent of CPU usage pushes the server up to 100 percent load, and you start having performance issues."
"An issue I encountered was around the integration of Identity. I lost some important information and I would like to see improvements with this."
"There is room for improvement in the product's AI capabilities and real-time data processing features."
"The support subscription models need improvement."
 

Pricing and Cost Advice

"AWS is not an expensive product."
"We are happy with the pricing."
"The price is good and licensing fees are paid on a monthly basis."
"The pricing is one of the best in the segment."
"It's paid on a monthly basis and you have to pay for the resources that you use."
"Some customers will provide their own license and others will purchase it directly from AWS."
"It is quite expensive in my very personal opinion. Going on-prem in a data center is, for sure, not as expensive as going to AWS, but when it comes to a point where you are raising and growing, it simply makes a lot of sense to stay in AWS. It is awesome in that way. I am not aware of any extra costs."
"It is very expensive, you have to be very cautious."
"There is a standard fee for a processing unit, they call them "dynos," and then you pay for add-ons."
"Its price is very good."
"The tool is free."
"I rate the tool's pricing a three out of ten."
"The price of Heroku could be less expensive."
"Customers need to purchase additional services because of the complexity of it."
"Microsoft Azure is not expensive. You pay for what you use. If you are using it everything could be expensive."
"This is an expensive product."
"The price of the solution could be less expensive and the pricing model could be less confusing."
"I pay for a yearly subscription."
"Their licensing costs might be a little bit lower, compared to AWS, but I'm not sure. I think we get licenses, especially on long-term projects, on a yearly basis. It could be cheaper."
"The licensing is pay per usage, so it can be both monthly and yearly."
"The cost-benefit equation for Azure is very good, particularly for small applications. However, Microsoft should do much, much more to improve how costs are communicated and how to forecast them. The Azure Pricing Calculator is not useful."
