Sakthivel Veeramuthu - PeerSpot reviewer
Easy to optimize for high performance and handle heavy traffic
Most of the features I liked were related to the performance during peak hours. Because I needed to optimize the Apache web server to run it as a high performer during my customers' usage, then I needed to reduce my Apache web server resource usage for that. So that part of the thing is what I was more interested in doing. So, I mainly liked the performance and security.
Krishnakumar Natarajan - PeerSpot reviewer
Designs and manages multiple websites while ensuring data backup and disaster recovery
I have experience with AWS, and I am most familiar with the server environment, as we just use the server environment and then use Microsoft products on an AWS environment. I have experience with Windows Server IIS, which I ran on my own on-premise data center. The website was developed and then hosted, and through IIS, we managed the servers. The manageability within the IIS environment is not very difficult. For server management, you need to ensure data backup, data restore, and you have a DR configured to keep the database intact. It was done on-premises, so I had no problem doing that. If you have to go to the cloud, then you should have the storage connected to the IIS server and also have a DR set up for that. I didn't use Microsoft Azure tools, but since it is a Microsoft product, Azure has all the portability, so you don't have to worry about compatibility on the cloud. On a scale of 1-10, I would rate this solution a 10.

Quotes from Members

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

Pros

"The open-source nature is one of its most significant advantages."
"The best thing about Apache is that it is open-source, so implementing my platform on-premises is less expansive than other solutions."
"It is more secure to use Apache and you will have fewer problems than other web services."
"Apache Web Server can be used as a proxy server"
"Its community is its most valuable feature. Solving problems is easier on Apache because so many people know this product."
"It's very stable, and it hosts one of the biggest of many biggest web applications in the world."
"Most of the features I liked were related to the performance during peak hours."
"Apache has proven to be incredibly reliable, and everything has operated smoothly without encountering any issues."
"The solution is easy to use and connects with Microsoft."
"It helps scan and mitigates our vulnerabilities using the best protocols to secure our environment."
"IIS's best features are its management console and stability."
"The solution is easy to use, easy to maintain and isn't too technical."
"What I like the most is that it is easy to use."
"The solution is the easiest way to publish applications which have been designed by older development tools."
"When you are working with Microsoft solutions, you will see that the integration with the operating system, and implementing some security features, are easier in IIS than when using another solution."
"The product is easy to use."
 

Cons

"The product's initial setup process could be easier for users."
"There isn't a dedicated customer support available"
"A monitoring interface would be great for this product. The monitoring dashboards for Apache's models are not included in the basic installation. You can install the basic monitoring model, then connect this model to another monitoring system."
"For NGINX, I think it has NGINX Management Suite, which is GUI-based and allows you to manage your configuration via the user interface, but Apache fails to offer such capabilities to users."
"Things change very fast. We're always on the lookout for better approaches and tools. If the solution falls behind, we may have to switch."
"It would be great if technical support for Apache were available in Iran. It is a very important need."
"In future releases, I would like to see better server optimization."
"So far, for us, everything is okay."
"The initial setup could be made easier."
"The solution is slow and could have better performance."
"IIS has some stability issues and needs restarting."
"The documentation is not very detailed. They need to improve it and add to it. They should ensure there are lots of visuals to help users better understand the solution."
"We've never had any issues with the solution, but it's still nice to have overall improvements on it. It could be easier and faster to use, for example."
"Finding different settings can be difficult if you don't know where to look."
"This solution needs to be easier for cases where you want to have an IIS cluster."
"The solution's black box is not fast."
 

Pricing and Cost Advice

"It is an open-source solution."
"It is a free-of-cost solution."
"There is no licensing cost for the product."
"The apache software is free, open-source."
"I didn't need to get an additional license for the solution since it was included in my server."
"The price is good."
"Users can get a subscription-based license or a perpetual license for IIS."
"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."
"The price of the cloud system is a bit high."
"IIS comes along with an OS license from Microsoft. Others can opt for a perpetual-based licensing model to be able to use the system."
"The licensing cost is dependent on the usage."
"I think it's part of the Windows Server, so you won't have any other costs to add in order to use the IIS service."
