Asif  Meem - PeerSpot reviewer
Senior Machine Learning Engineer at sportsbet
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.
Syed Abid  - PeerSpot reviewer

Versatile integrations and reliable customer satisfaction elevate cloud service experience
For Microsoft Azure improvement, they need to enhance their support system. The first level of support should be improved in terms of quality and response time. They need more technical support at the first level, as there are currently only one or two technical people among five to ten staff members at this level. They should ensure that the first level support is more technical because we normally provide services to technical users ourselves. When an issue arises, it usually escalates to the second or third level. When facing first level support, they may have limited knowledge and only collect screenshots to forward to their seniors. They should ensure that the first level support is aligned with L2 and L3 to better assist us, especially since we mention in the ticket that our issues are related to specific problems and require that sort of support.

Quotes from Members

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

Pros

"We use AWS for multiple purposes, such as developing APIs and API integration using API Gateway. We use API Gateway, Python Combinator, Lambda Glue, and ETL Process. We have used EMR for big data processing. If we need a tool for computing, we go with the Lamda DMS. There are many services available in AWS that meet our needs."
"It works pretty seamlessly."
"IaaS with easy management and rapid implementation using Python Django Mezzanine."
"A scalable and secure product"
"This solution is very easy to use and it has a professional interface."
"They are all excellent in terms of offering great functionality."
"The solution is very easy to use, the product is nice and stable, its performance is great, and the technical support has been good."
"There is less work for the DBAs, everything is handled in AWS itself."
"IBM Public Cloud is a stable solution; it gives you SLA notifications all the time of what could be done, what is going to happen in the next hour regarding downtime, or anything that affects you, and so far I never noticed any issue, so I'm very happy with the solution."
"One of the features that I really like about IBM Cloud is the flexibility where you can order your own hardware."
"It provides robust analytics and management tools to give customers complete visibility into their environment and infrastructure."
"Overall, I would say that IBM Cloud is stable, straightforward, and is a good service."
"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."
"In terms of performance, resiliency, and availability, it is second to none."
"It is a scalable product. You can scale it up and down."
"On the production side, we are seeing a 200% ROI."
"It's been pretty useful in terms of migration and disaster recovery strategy."
"The initial setup is straightforward."
"I would definitely recommend Azure because it's an enterprise trade cloud platform and can provide valuable insights of your data and of metrics of data sources in real time."
"The solution is easy to use, it's great for ready-to-use services, and it's set up to handle any cloud requirement."
"There are many benefits, for example, there is a special customized portal for all apps and services built in Azure AD (myapps.microsoft.com) with a seamless single sign-on experience for the users in AD or Office 365."
"I would definitely recommend Azure as a solution because it is a popular product by a major brand and it is very easy to use."
"The ability to kick start a new web application or website and having them up and running in matter of minutes still amazes me."
"It has multiple features that can be used from the start."
 

Cons

"AWS could be improved with more integration, but I can see that they're developing these features and working very hard on their platform."
"The pricing of AWS is very unclear. They make it quite confusing."
"There have been some issues in the past when it comes to file integrations in AWS's cloud products."
"One area that could be improved is in data management. They could improve on the data side. For example, I see others with better cloud services and larger data computing capabilities."
"Not all of the functionality is available in Europe and our customers in France want to be able to use features that are only available in the US."
"An area for improvement would be API creation - a lot of tools are provided, but there can be issues with integrating them."
"They should look into reducing the price of this solution to stay competitive."
"Its only cons are on the data warehouse side. AWS' data warehouse Redshift is not as good as it should be."
"This solution can be very slow, which was a big problem for us."
"It will be challenging to implement if you do not have any experience."
"The deployment can be a bit of a pain. There are a lot of packages and a lot of options and it can require complex configuration to get it right."
"I would like to see a more user-friendly deployment process in the next release of this solution."
"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."
"Support could be improved."
"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."
"It will be challenging to implement if you do not have any experience."
"The solution could improve by being more user-friendly."
"The support, the cost, the way they have the tiers, this could all be improved."
"Microsoft Azure is not always a user-friendly solution. For the end-users, sometimes it's not really fun to use or simple to use."
"It is constantly updating. There are weekly releases, sometimes daily releases, and there should be fewer that are consolidated into one."
"The solution should emulate what MuleSoft is doing."
"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."
"I would prefer Microsoft Azure to increase the free trial, then developers can take advantage, and it could increase their sales."
"It was quite frustrating that an issue with their product required an upgrade to get serviced when it was a failure that they were responsible for."
 

Pricing and Cost Advice

"Amazon AWS is offering different pricing, and saving plans, it's very easy for a customer to consider the Amazon AWS service."
"We need to pay for everything. If someone is a personal user, they get one year free. But if you are using this as a professional or enterprise solution, then your company has to pay. The license pricing is comparable to that of competitors'."
"It is very expensive, you have to be very cautious."
"This is a subscription-based service and there are licensing fees."
"The pricing is fair."
"The solution is expensive, and I rate it an eight out of ten."
"When compared to GCP, Google, or Azure, the price could be lower."
"There are no additional costs beyond the standard licensing fees."
"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."
"The licensing fees are straightforward and predictable."
"We are using the trial version of this solution, so we have not paid anything."
"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."
"IBM has a lesser price compared to other cloud service providers like Azure and AWS."
"In order to be competitive, you have to commit to a contract for at least one year, but you pay a fixed monthly fee."
"It pretty much has a standard price. There is no hidden price with IBM Public Cloud."
"Pricing is not as fair as Amazon or Azure."
"It’s necessary to use third party products or to use good self-management economic tools"
"The pricing for us is higher because we are using IaaS."
"Keep to PaaS to gain the optimal benefits from an OPEX finance and resource perspective."
"It is competitive with other public cloud providers, and its price is very close to different cloud providers. There is not a noticeable difference between different cloud providers. Otherwise, it would be a risk for them to have services that were much more expensive than their competition. They're pretty much neck to neck on pricing."
"Monthly billing convenience reduced cost overheads up to 70 percent."
"The cost could definitely be lower."
"The cost is a little high and can be more competitive."
"I rate the tool's pricing a six out of ten."
