ROI

Sentiment score
6.4
Microsoft Azure saves costs and boosts efficiency with scalable cloud services, pay-as-you-go pricing, and reduced maintenance expenses.
Sentiment score
6.8
Users report positive ROI from Oracle Cloud, with effective cost optimization but initial expenses may delay returns up to two years.
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
6.5
Customer service is mixed; paid support is praised for responsiveness, while free options may face delays and complexity.
Sentiment score
6.3
Opinions on Oracle Cloud Infrastructure support vary, noting slow responses and complexity, with some appreciating improvements and collaboration.
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.
Oracle support is very friendly and provided free of cost.
Having a contact point from Oracle Cloud Infrastructure (OCI) allowed for direct email communication.
 

Scalability Issues

Sentiment score
7.7
Microsoft Azure excels in scalability and flexibility, supporting various workloads, though cost and limitations may concern some users.
Sentiment score
7.4
Oracle Cloud Infrastructure excels in scalability, offering flexibility and robust performance but requires manual configurations compared to some competitors.
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.
There are no issues with Oracle Cloud Infrastructure's support for scalability demands.
 

Stability Issues

Sentiment score
7.7
Microsoft Azure is highly reliable and scalable, despite occasional outages; users confidently rate it high for stability and performance.
Sentiment score
7.9
OCI offers reliable performance and stability with high ratings, despite initial challenges and concerns about support responsiveness.
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

Microsoft Azure needs pricing transparency, intuitive interface, improved support, better technical features, and refined management tools for users.
Oracle Cloud users seek better support, documentation, scalability, integration, interface, and competitive pricing compared to AWS and Azure.
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.
AWS services typically offer more flexibility to end users.
 

Setup Cost

Microsoft Azure offers flexible, competitive pricing, yet complexity makes AWS and GCP potentially more cost-effective for enterprises.
Oracle Cloud Infrastructure offers flexible pricing, perceived as cost-effective and competitive compared to AWS and Azure.
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.
A 50% cost reduction compared to AWS was estimated.
 

Valuable Features

Microsoft Azure offers flexibility, scalability, global presence, integration, security, ease of use, and cost-effectiveness for enhanced organizational infrastructure.
Oracle Cloud Infrastructure offers flexible, secure, and scalable solutions with seamless integration, cost-efficiency, and global availability for disaster recovery.
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.
Applications using Oracle Database not only work seamlessly on Oracle Cloud Infrastructure (OCI) but also benefit from a 25% offset on Oracle Database licenses.

Featured Reviews

Sylvain CAILLAU - PeerSpot reviewer
Effective public cloud deployment enhances operational flexibility with room for cost management improvement
I am not having enough experience to answer what the room for improvement is for Microsoft Azure, but maybe not only in the technical aspect. The design could be a little bit better, the technical support could be better, and the price could be even cheaper. We still have to manage the cost and the FinOps activities, which I see is demanding before we can be sure of a good choice. When it's done, it's acceptable, so could it be made easier to do? I don't know, but it is engaging us in some extra work. That's why I say not ten out of ten, but only eight out of ten.
Labhesh Hase - PeerSpot reviewer
Cost-effectiveness and pricing consistency support diverse high-intensity applications
The services of Oracle Cloud Infrastructure (OCI) are quite competent when compared to AWS Cloud, and they are also lower in cost. We use compute, storage, and network services. A notable feature is Oracle Cloud Infrastructure's consistent global pricing, which is advantageous. Furthermore, applications using Oracle Database not only work seamlessly on Oracle Cloud Infrastructure (OCI) but also benefit from a 25% offset on Oracle Database licenses.
