Executive SummaryUpdated on Jun 3, 2026

Zend PHP Engine and IIS are key players in the web server arena. Zend PHP Engine holds an edge with its focus on PHP applications, providing superior runtime performance and flexibility, while IIS excels in Microsoft environment integration.

Features: Zend PHP Engine stands out for executing PHP scripts, offering robust debugging tools, seamless PHP deployment, and enhanced runtime performance. It excels with PHP-centric operations and integration. IIS provides a comprehensive suite of tools, notably its management console, enabling smooth operation within Windows ecosystems. It's valued for stability, ease of use, and security enhancements.

Room for Improvement: Zend PHP Engine could enhance compatibility with non-PHP languages, streamline multi-environment deployments, and improve support for various integration tools. IIS might benefit from refining its cross-platform capabilities, simplifying configuration for non-Windows environments, and enhancing support for third-party applications to widen its usability.

Ease of Deployment and Customer Service: Zend PHP Engine offers flexible, PHP-centered deployment with a focus on customizable PHP setups and PHP-specific troubleshooting support. IIS offers streamlined deployment in Microsoft environments, backed by ample documentation and robust enterprise-grade support, enhancing overall user confidence.

Pricing and ROI: Zend PHP Engine involves higher setup costs due to licensing for premium features, yet delivers strong ROI through enhanced PHP project performance. IIS is perceived as more cost-effective, especially for organizations already within Microsoft's ecosystem, offering high ROI potential due to seamless integration and scalability benefits.

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

"IIS's best features are its management console and stability."

"It helps scan and mitigates our vulnerabilities using the best protocols to secure our environment."

"It was crucial and it definitely paid off."

"The solution is the easiest way to publish applications which have been designed by older development tools."

"The solution is very simple to use and easy to deploy."

"We use the solution for our customer's web applications."

"The stability is better than it was in the past."

"It is a Microsoft product that is easy to use and to host local and public websites."

More IIS pros

"Faster web app implementation, when PHP dev is required by customers."

"The cache modules that Zend provides have been able to optimize and accelerate the loading of the pages when there was exponential growth in data volume and quantity of requests. At the same time, the monitoring console allowed us to have a real-time understanding of the resources and to make decisions when they were at the limit."

"This solution is really easy for me to use."

"The most valuable feature of this solution is the speed at which it compiles and sends the dynamic cache."

"No issues with stability encountered."

"The fact that it is available open-source is the best feature."

"It offers good support for various types of classes, along with many open source libraries that we can readily utilize in our application development process. This gives us a lot of options when it comes to custom development solutions, without having to worry about licensing or other programming-related issues."

"Zend Engine gives the flexibility to use external modules to easily expand the functionalities you need for your web project."

More Zend PHP Engine pros

Cons

"The solution should improve the cluster environment and load balancing."

"The solution's stability needs improvement."

"It should be more user-friendly because unless you know how IIS works as a Microsoft product, a system admin cannot just manage it."

"The solution could offer better pricing."

"Finding the correct options are not more intuitive, and it should be."

"Occasionally, we encounter performance issues with IIS where it becomes unresponsive and requires a solution restart."

"The graphical user interface has room for improvement and can be more user-friendly."

"I would like to see NLB features in IIS."

More IIS cons

"In terms of improvement, it doesn't support concurrent processing. When we want to process anything on a concurrent basis, we have to divide it into a number of things, like a queue, or we have to run it using Cron jobs. We would like to have the capability to run any thread or process in parallel."

"Integrating AI tools would make PHP more competitive, as other tools already have AI features."

"The main area that Zend needs to improve is to support asynchronous programming tasks, which is facilitated in PHP 7, but not at the same degree as HHVM."

"The platform is not satisfying to me -- it is just not up to standards performance wise."

"The solution can be quicker."

"The process of installing and configuring the product is a bit complex and could be improved."

"Integration of MVC with ORM tools for PHP is okay, but lacking a short list of decent ORM tools for PHP to choose from; there is ample room for improvement in both areas."

"A general scripting language should be further developed and should be embedded into it."

More Zend PHP Engine cons

Pricing and Cost Advice

"We pay a yearly licensing fee for the solution."

"Users can get a subscription-based license or a perpetual license for IIS."

"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."

"IIS is expensive."

"We purchased a Microsoft Windows license and the license for IIS came in the package."

"IIS's pricing is not expensive."

"This solution comes included with Windows Server."

"There is no license needed to use the solution."

More IIS pricing and cost advice

"The solution is open source and you just pay for the server cost."

"The Zend PHP engine is open source technology, so there's no need for us to worry about licensing or other costs."

"Its pricing depends on the number of users."

"No problem with pricing and licensing, as tools are open source. You have to consider training cost, mindset setup cost, as part of the TCO."

"Zend PHP Engine is not an expensive solution."
