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

"One of the most valuable features is that Amazon AWS has a lot of data centers and regions where we can position our virtual machines for leverage. Amazon AWS is also easy to use. You can quickly spin up something, use Explorer, building proofs of concept, things like that. Once the proof of concept is built once and we know how things are going to look from a production perspective, we try to move everything to the data centers. These features and the ease of use are the main reasons why we use AWS."
"I am very impressed by the solution's stability."
"I like the auto-scaling functionality and compliance requirements, whichever they are requesting."
"There is no downtime. The solution is reliable."
"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 a flexible solution."
"Stable platform with a straightforward setup. It's user-friendly, with more reliable servers compared to the competition."
"I am happy with the dashboard."
"The availability is second to none. Customer support is very good."
"The initial setup was very easy. It's quite straightforward. Deployment took about fifteen minutes. Everything is well organized."
"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."
"For non-complex applications, the IBM Cloud works fine and the price is much lower than the competitors."
"An advantage of IBM Public Cloud is the bare metal server. We can take the bare metal server. It's not shared with anyone. We can deploy our applications without sharing them with anyone. That is an advantage of IBM Public Cloud."
"This is a predictable and dependable service."
"This product is very good because it is accessible in remote locations, and anyone can deploy from any place."
"Azure Active Directory: Has powerful security and auditing capabilities that we use to secure all our apps."
"It very quickly provisions servers, infrastructure, and apps on the fly and complies with security requirements and data safety."
"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."
"We have found the most valuable feature to be the pricing calculator."
"The solution is stable."
"It is easy to install."
"Good security, scalability, and elasticity."
"The best features of Microsoft Azure are the interface and the ease of use of that interface, which is very friendly."
 

Cons

"Its only cons are on the data warehouse side. AWS' data warehouse Redshift is not as good as it should be."
"Monthly costs can be high if you don't maintain your usage"
"Recently, new dashboards have been launched. This new UI is an improvement that they have made."
"They need to improve the engines' availability of services since they have been reducing that availability."
"The networking models used in AWS, while functional, do have room for improvement. This is especially the fact, considering that they are built/presented from a systems perspective."
"Amazon support could be better."
"One of the problems that I have seen is that some of the products are not as mature as others."
"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."
"It could be more secure."
"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."
"There is not a lot of support for this solution, which is something that needs to be improved."
"The product should offer more computing, similar to Amazon."
"Support could be improved."
"The solution’s pricing could be improved."
"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."
"The connectivity and speed of IBM Public Cloud are much lower compared to the competition."
"Microsoft Azure needs to be simplified to make it better understood for users."
"The main issue is the lack of notifications for updates. Processes for certain operations, like connecting to Git repositories, have changed without sufficient communication. A system to announce or update users about these changes would be very helpful."
"An issue I encountered was around the integration of Identity. I lost some important information and I would like to see improvements with this."
"Azure could be improved with better security. The world is changing and their security could be better. Compared to five years ago, many of these cloud systems are a lot better, especially since you can set up a private cloud and configure your services to make it more secure."
"For deploying multiple resources in a big number, such as in hundreds, we need a streamlined process and more user-friendly scrips. The scripts have to be more user-friendly, and they should also supply some standard templates to deploy multiple resources at a time. Currently, it is very easy to deploy a couple of resources, but if you want to deploy multiple resources, it becomes complex. The material that they provide for integration with an existing on-prem data center is complex. They have to make them user-friendly. The scripts related to resource management need to be simplified."
"As compared to AWS, Azure can improve its functionality. In terms of the feature list, it is still lacking a bit as compared to AWS. AWS supports lots of types of operating systems, which Azure is still catching up with. Azure is mainly focused on the Windows system, and it is not yet there in terms of integration with other operating systems like Linux, Unix. Azure is slowly catching up."
"Microsoft Azure could improve by being more secure."
"Pricing is one area where Azure has room for improvement. There should be some due consideration. Azure has solved some issues with pricing from the development team's standpoint, but it is still quite costly. They should also offer a trial period for the individual platform solutions. I think that would be pretty handy for the developers."
 

Pricing and Cost Advice

"To anyone thinking about using AWS, I would suggest carefully designing your implementation. This is very important because it will impact the monthly cost of the solution. You need to think ahead and talk with your staff to find opportunities to make this more efficient."
"When you compare Amazon AWS to Microsoft Azure, the pricing of both is almost the same. There are some instances when one is cheaper than the other in one area but it is difficult to pinpoint which one is cheaper because it depends upon a lot of factors, such as the use case. However, the overall price of both solutions could be reduced."
"Amazon AWS could have more options and transparency in its pricing model. You need in-depth knowledge to adopt AWS. So someone without that knowledge base might not understand all of the costs associated with AWS."
"A few of our customers pay for it yearly and monthly. Sometimes, when it's related to the data, the pricing seems to be high. It could be cheaper on a transactional basis."
"They have different pricing models for each suite of services."
"Licensing fees depend on the contract. It can be monthly or on-demand resources."
"The price of the solution is fair compared to competitors."
"The price is good and licensing fees are paid on a monthly basis."
"In order to be competitive, you have to commit to a contract for at least one year, but you pay a fixed monthly fee."
"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."
"It pretty much has a standard price. There is no hidden price with IBM Public Cloud."
"The licensing fees are straightforward and predictable."
"Pricing is not as fair as Amazon or Azure."
"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."
"Currently, we do not have anything reserved. There are no reservations that we have built into the Azure environment, so all of our licensing is on a consumption basis. As things spin up, those licenses spin up."
"Its costing can be improved. Its licensing is monthly. In addition to the standard license fee, there is a transactional cost."
"The pricing model can be improved because we find that Azure pricing is a bit high."
"With every cloud solution, you have to know what you need and the cost can be fine. The price can be a little bit high depending on how you manage your costs, but overall it's still a bit cheaper than an on-premise solution but with the advantage of flexibility. You're always up to date with the software, you only need to use it. You no longer have to be concerned with the on-premise physical security. We do not need to create a data center, it's more convenient for us."
"The pricing for the end-user packages is a bit high. It is full of very interesting services, but I would still like it to be less expensive."
"I would like to see it more easily accessible."
"Several thousand dollars and counting, we haven't needed to upgrade on premises hardware (In fact we eliminated all of the old on-premises hardware and run 100% on Azure) or pay for it's maintenance, power etc."
"The price of the solution is reasonable."
