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.

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.

Good stability and scalability with excellent additional services
The features that are on offer are pretty standard. The pricing and services that surround the solution are great. For example, if we need to find a partner in a country where they do not have a cloud, they will help us find that partner. Solutions such as Amazon and Oracle do not offer this level of service. The solution has quite good documentation.

Quotes from Members

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

Pros

"The technical support of AWS is very good; when I need something, they reach out to me fast."
"Everything is good in this solution."
"It has several valuable features, but the load balancer, auto-scaling, and RDS database are the main ones. It is a complete cloud infrastructure solution."
"The most valuable feature is the availability, as we work in different availability zones."
"Easy to upgrade, easy to expand storage and change your EC2 types."
"We pretty much like everything and we are excited about the seamless capability the EC2 service is offering."
"We like the that, within the public subnet of this solution, a new instance of the tool is launched when it detects an issue, in order to prevent interruptions in performance."
"The solution is absolutely stable, and this is one of its best features."
"Much more intuitive and more visual than AWS. More obvious where things are and how to change their configurations, etc."
"The stability is good, there is compliance with the SLAs, and we have not encountered any issues in this domain."
"It's a great solution. It's so customizable. Every user can create dashboards to suit their needs. We can create and share them with our teammates easily, too."
"If you're interested in going with Microsoft, my advice would be to do it. Everybody's using Microsoft."
"Overall, we've been quite happy with the product."
"Microsoft Azure has a lot of useful features. They have databases, application services, PaaS solutions, such as platform and infrastructure services. The virtual machines' functions and services are good."
"If you need a quick mobile solution, particularly an enterprise mobile solution, this is a wonderful choice."
"The solution reduces work for our IT teams, they don't have to keep things up to date, and we can concentrate on our mission, with help from Microsoft to migrate applications to the latest release and support efforts, which saves us a lot of time."
"The pricing and services that surround the solution are great. For example, if we need to find a partner in a country where they do not have a cloud, they will help us find that partner. Solutions such as Amazon and Oracle do not offer this level of service."
"The pricing and services that surround the solution are great, and if we need to find a partner in a country where they do not have a cloud, they will help us find that partner, which is a level of service that solutions such as Amazon and Oracle do not offer."
"The initial setup process is more accessible than one of its competitors."
 

Cons

"The initial setup is not easy at all."
"There are plenty of areas for improvement. For example, the ease of tagging could be improved. The tool could integrate AI tools to identify better and manage costs. Calculating the cost of some services could be more straightforward."
"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 pricing of the solution could be better. It's a little pricey."
"Its subscription model or pricing model is too complex, which should be improved."
"If Amazon AWS can offer more self-paced learning tools, on their website, on CBT, it'll be easier for more people to familiarize themselves with their service. Especially when they are delivering new services from time to time. Educational tools that can help users familiarize themselves with their service. It would be great."
"Monitoring still needs to be improved."
"As far as the automation is concerned, the backups should be scaled."
"Stability can suffer in the context of a large architecture."
"I would like to see better policy-based management and everything related to security management could have been better integrated."
"The subscriptions are complicated."
"More integration with other platforms is what I would like included in the next release for this solution."
"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."
"The cost of the product is too high. It would be ideal if they could lower it a bit for their customers."
"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."
"The support, the cost, the way they have the tiers, this could all be improved."
"The solution needs to provide a bigger portfolio of services. The solution could use more advanced monitoring."
"The solution could use more advanced monitoring."
"NTT Cloud’s performance could be better."
 

Pricing and Cost Advice

"The licensing cost varies with the project involved."
"The price, in general, could be better."
"This is not an expensive product but it would be an improvement if the price were cheaper."
"It's expensive."
"From a cost perspective, Amazon AWS is excellent. You need to pay for a license to use AWS, and the license could be cheaper, but in each of the cases and instances I've used AWS, there has been a good chance to save money."
"It's not very pricey, but it could be cheaper."
"In terms of price, there are less expensive options."
"The pricing is reasonable. It's not expensive, nor will it be cheap, but the free credits initially given provide leverage for new companies to start their businesses."
"We have an annual license subscription to use the solution."
"It is similar to AWS, where it is on-demand and is billed monthly."
"Pricing is very difficult to guesstimate. With so many a la carte options and individual pricing it can be a hassle to understand."
"Customers need to purchase additional services because of the complexity of it."
"The cost of the solution could be reduced. However, I am using the free version."
"Keep to PaaS to gain the optimal benefits from an OPEX finance and resource perspective."
"I pay for a yearly subscription."
"Its costing can be improved. Its licensing is monthly. In addition to the standard license fee, there is a transactional cost."
"I rate the product’s pricing a four out of ten."
