Review summaries and opinions

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

ROI

Sentiment score
7.9
AWS offers cost savings, scalability, and agility with a pay-as-you-go model, attracting clients and reducing overhead.
Sentiment score
6.4
Microsoft Azure reduces costs with scalable services, pay-as-you-go model, and improved infrastructure, enhancing long-term returns and performance.
The value for money is good, and Microsoft Azure has positively impacted our operational costs.
When we use Microsoft Azure, it provides enhanced security from our perspective, though I am not certain about the financial return on investment or benefits for our users as I do not have that information.
 

Customer Service

Sentiment score
6.9
AWS is favored for reliable support and problem-solving despite concerns over response times and communication efficiency.
Sentiment score
6.5
Microsoft Azure's support is often effective, yet some face delays; higher-tier support and self-help resources improve experiences.
Reaching out to them and talking is different from receiving a complete solution to your problem.
Amazon AWS has good technical engineers available, making their customer service reliable.
Microsoft needs to engage L3 and L2 in support when specified in service tickets.
The support from Microsoft Azure is good.
Regarding technical support from Microsoft, I find they are responsive and helpful, depending on which support package you're on.
 

Scalability Issues

Sentiment score
7.9
Amazon AWS provides seamless vertical and horizontal scalability, supporting diverse customer needs from startups to large enterprises efficiently.
Sentiment score
7.7
Microsoft Azure offers scalable solutions, but users face challenges with costs and resource limits, leading some to prefer competitors.
The scalability of Amazon AWS is excellent.
Amazon AWS provides strong scalability features, but the scaling process could be made more straightforward.
Microsoft Azure is not just one product; it is a platform with multiple products within Microsoft Azure, and I would say it is scalable and would rate it a nine.
The scalability of Microsoft Azure is excellent for growth and adaptation, depending on company requirements.
It has different kinds of designs that allow for management and deployment in multi-zones, offering both scalable and non-scalable options.
 

Stability Issues

Sentiment score
8.1
Amazon AWS is highly reliable with minimal issues, strong infrastructure, and stability often rated between eight and nine.
Sentiment score
7.7
Microsoft Azure is stable with good uptime, though stability varies by configuration; users generally rate it highly.
We noticed a few critical servers went down due to a Microsoft Azure-end hardware issue.
We are now migrating clients without the zoning into mandatory multi-zone deployments, so if one zone goes down, their application and database remain live.
Microsoft Azure is quite stable, but recent outages and security issues have slightly decreased my confidence.
 

Room For Improvement

AWS users face challenges in cost, support, complexity, security, documentation, and features, with improvements needed in usability and integration.
Microsoft Azure users seek simplified pricing, improved security, better integration, enhanced documentation, responsive support, and intuitive management tools.
Amazon AWS could improve its user interface to make it more user-friendly, especially for people who are not highly technical.
When using scripts for APIs to fetch data, they don't match the data exactly with the request.
Recent outages and security issues are also a concern, causing a decrease in confidence, especially when partnering with third-party companies.
The administrative side is suitable for technical people, but our finance and HR super users find it less user-friendly, as they prefer drag-and-drop features to build their own solutions without contacting IT.
There is still room for improvement in terms of pricing.
 

Setup Cost

AWS offers scalable, flexible pricing suited for enterprises but requires careful management to avoid high costs from storage and data transfer.
Microsoft Azure provides flexible pricing with pay-as-you-go, free tiers, and discounts, emphasizing cost-effectiveness despite complexity.
After three to four years, if you are not managing it correctly, you will be paying more than an on-premise solution, which applies to all cloud providers, so you must regularly maintain and manage for efficiency.
Currently, Amazon AWS is known to be on the higher price range because popular and in-demand services often come at a premium.
Microsoft solutions might be cheaper than some services like AWS, but some solutions may be more expensive depending on the services compared.
Copilot is expensive based on recent pricing for our POC.
They have discounts and also provide promotions for a three-year reservation which comes with significant discounts on the infrastructure part.
 

Valuable Features

Amazon AWS offers scalable, secure, and flexible cloud services with automation, diverse tools, and excellent support for efficient resource management.
Microsoft Azure is praised for scalability, ease of use, diverse services, strong security, and seamless integration with various technologies.
Amazon AWS offers flexibility and scalability.
One aspect I appreciate in Amazon AWS is their support team, which is excellent.
Power BI, another feature of Azure, is extremely elegant and has robust features that support forecasting using R and Python.
If Microsoft gives a report, such as a server performance report in a detailed way, which shows what is consuming more CPU, memory, and disk IO, and network utilization during a particular time, it would be helpful to visualize that information.
What is very interesting in terms of scalability is the automatic possibilities to provision some new machines to be able to absorb the number of users we have in the system.

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.
