What is most valuable?
Auto Scaling and CloudWatch Logs are the most valuable features. With just a few criteria to scale in/out of, you can save the life and time for DevOps.
The CloudWatch Logs feature provides many plugins, so that we are able to manage various types of logs centrally.
How has it helped my organization?
In the era, we used private clouds as network virtualization must be controlled by the IT division, server rooms were in the remote branches and DevOps were distributed in various areas. Now, we can use the same API and the same workflow without considering to centralize the logs.
What needs improvement?
IaaS is sometimes way too complicated to complete one task.
For how long have I used the solution?
I have used this solution for around eight months.
What do I think about the stability of the solution?
So far, the VPC is sometimes not that reliable. Therefore, we have to set up a redundant VPC to make sure the connection is always available.
What do I think about the scalability of the solution?
We do not have any scalability issues until now.
How are customer service and technical support?
I have never used technical support.
Which solution did I use previously and why did I switch?
Previously, we surveyed OpenStack. However, due to the time, budget and manpower limitations, building a private cloud is not practical in our case.
How was the initial setup?
Managing IaaS was very difficult in the beginning, i.e., tons of jargon to get up and I struggled for months.
Which other solutions did I evaluate?
Try the Google Cloud Platform (GCP). It is yet another good choice because sometimes, what you need is just a platform and not to build a platform from the infrastructure.
What other advice do I have?
When your division grows to a certain scale and you really need DevOps, then you could move either to a private/public cloud. Otherwise, it is a waste of time and money.
