What is our primary use case?
I believe we have six instances of Savings Plans.
We have SAP S/4 HANA. This is the name of the ERP. We have instances and we have a Linux instance using database. We are also using application instances for making outbound calls to connect the users to the solution.
So, we have Safety and AWS Lex service that supports communication with the user. Then, if it is a call later on in the total area, it informs a certain instance.
How has it helped my organization?
AWS is consistently innovating and releasing new products and features. We have a high awareness of these advancements and often adopt new solutions when they align with our needs. The availability solution in the console is a good example. It's very nice how Amazon prioritizes cost optimization and provides robust analytics tools.
What is most valuable?
Around the world, we have between 25% and 30% savings (cost reductions) when we change from traditionally reserved instances to Savings Plans. We have experience with existing Reserved Instance commitments.
AWS is, in my personal opinion, a good solution for user environments. AWS is very flexible; we can extend the size of the storage, programmatically scale parts of the system, and change systems. If we change the size of the system, it will still have good performance. AWS has a lot of flexibility.
What needs improvement?
AWS make it easier to configure the VPN,
For how long have I used the solution?
I have been using it for two years.
What do I think about the stability of the solution?
We've been an Amazon user for five years (since 2017, approximately)and haven't experienced any interruptions. Our reliability with AWS has been nearly 100%.
What do I think about the scalability of the solution?
We have a considerable number of users utilizing the solution.
One being the worst and ten being the best, I would rate it a seven out of ten. AWS is direct, and the performance is simple.
How are customer service and support?
Technical support is excellent.

How was the initial setup?
The setup was generally easy. The most complex aspect was configuring the VPN. While not overly difficult, it was more challenging compared to setting up other VPNs.
However, once we resolved the initial VPN configuration issue, everything has been smooth sailing.
It's a matter of familiarity. Initially, the technology is unfamiliar, but with experience, configuration becomes easier.
Deployment time: We didn't have any problems. We determined the implementation date, considered the transition for ourselves and our users, and it went smoothly.
Maintenance: There isn't much required. If the stability, resolution, and capacity planning are correct for our needs, or if we need to expand storage, then maintenance is mostly handled by our banking team.
What about the implementation team?
We didn't need a big team. We contacted Amazon through their contact center, and I believe a few people from their end were involved in assisting us.
What was our ROI?
In the beginning, we debated between maintaining our own platform and using AWS. For years, we had a similar resource expenditure with both options.
However, after five years with AWS, our technical needs grew, and we needed additional resources. I don't recall the exact figures, but AWS provided new instances, versions, and capacity. We only had to change the box. This led to a good return on investment due to the flexibility and scalability AWS offered.
What's my experience with pricing, setup cost, and licensing?
We have a fixed cost of five thousand, plus an additional six thousand per month. So, it is about seventy-two thousand annually.
Compared to Azure or Google, the solution is much cheaper.
Moreover, the main difference for us is that AWS offers more functionalities and tools compared to the other solutions.
What other advice do I have?
I have recommended it to our friends and colleagues in various settings, such as webcasts and meetings. Some people are unfamiliar with the solution, especially those heavily invested in Microsoft solutions, who might find more savings with Microsoft's specific licensing models.
However, I believe AWS Savings Plans isn't truly competitive in that regard. For instance, running SQL or Microsoft servers on AWS is more expensive than using a dedicated server. This is a concern raised by CIOs who inquire about Azure because it can be more cost-effective in certain scenarios, particularly with Microsoft Hypervisors.
Overall, I would rate the solution a ten out of ten.
