NGINX vs TIBCO ActiveSpaces

• Straight-forward configuration format that users of all skill levels can learn, and yet is powerful enough for the huge breadth of features that Nginx provides.
• Massive scale right out the box. We've never had a Nginx instance overwhelmed by requests, and if we did it would be trivial to spin up more Nginx instances to handle the load.
• SSL termination means that we can deliver content over HTTPS without needing our individual services to require TLS support. This saves us a lot of time and headache while keeping us secure.
• Nginx is open-source and free, meaning that anyone can use it to power their services, from individual projects to billion-dollar websites.

• Tibco ActiveSpaces is an excellent caching tool. With good design, we can haven a efficient cache layer, that can respond to business needs in sub-seconds (milliseconds) rather than seconds / minutes to respond. This is specially useful for improving the efficiency of the services used in customer interactions.. like login, serving billing information, serving the customer's service usage and any other information customer is interested in accessing frequently.
• System process can also use the ActiveSpaces . By caching the information frequently used by the system processes, the data cab be accessed more frequently. And without much disruptions.
• If you are already using TIBCO tools, then ActiveSpaces is the right choice to use, as the product is well integrated with all the TIBCO Suite of products. ActiveSpaces integrates well with most common products like TIBCO BusinessWorks, TIBCO BusinessEvents etc.
• ActiveSpaces can be easily deployed to a target (TIBCO) environment, with very little additional effort. Although there is an effort required to deploy them.
• ActiveSpaces is supported by TIBCO BusinessWorks 5.13 and TIBCO BusinessWorks 6.x. Hence you are not forced to use any version of TIBCO BW, just because you have to use TIBCO ActiveSpaces.

• Customer support can be strangely condescending, perhaps it's a language issue?
• I find it a little weird how the release versions used for Nginx+ aren't the same as for open source version. It can be very confusing to determine the cross-compatibility of modules, etc., because of this.
• It seems like some (most?) modules on their own site are ancient and no longer supported, so their documentation in this area needs work.
• It's difficult to navigate between nginx.com commercial site and customer support. They need to be integrated together.
• I'd love to see more work done on nginx+ monitoring without requiring logging every request. I understand that many statistics can only be derived from logs, but plenty should work without that. Logging is not an option in many environments.

• ActiveSpaces 3.2 is not compatible with the latest version of TIBCO Business Event 5.x. And ActiveSpaces 2.x is not compatible with ActiveSpaces 3.x hence there is a big difference in the BusinessEvents supported version of AS and the latest.
• ActiveSpaces takes more disc space and TIBCO does not offer data compression logic out of the box. Developers need to do extra coding to use java snippets to compress and decompress the payload. Although the data compression gives must better performance and speed to the system.
• The compression and decompression API are not offered by TIBCO out of the box, which is a shame. These are so easy and simple to implement, still TIBCOdoes not provide them as an option out of the box.

• Improved the reliability of our site. Before using Nginx, with Apache as our app server, there were times when we had to manually go in and restart Apache to bring the site back online. We've never had to do that with Nginx.
• Made our web server more memory efficient -- Nginx has a very small memory footprint, on the order of under 100 MB. This makes it suitable even for cheap VPS machines.
• The Nginx community provides online examples of configurations, so it saves us time in writing the config files from scratch.

• Developers with basic knowledge of TIBCO and general data knowledge can easily design and develop an ActiveSpaces based cached solution. As the ActiveSpaces concepts are very simple and easy to understand.
• Some business areas can predict the high influx of a service usage during a certain period. Business will be highly rewarded if they can identify these business areas and provide a cached solution using TIBCO AS.
• Again, this is not a TIBCO ActiveSpaces only advantage and this is true for any/all caching products.
• Some examples for the previous points are
• a. telecom company pre-loading (eager load) customer's usage for the last month, right before releasing/issuing the bills to the customers.
• b. Airline industry loading the customer's itinerary a week before his travel start date. Hence the last minute scrambling to fetch the customer's itinerary travel plans can be avoided.
