IBM DataPower Gateway vs. NGINX

WebSphere DataPower Gateway is really beneficial if you are trying to integrate two or more systems. It provides you with comfort and peace of mind by creating a DMZ zone for the services which are going out of the intranet to hit external clients APIs. It is greatly recommended if you have a very high volume service or API which is being used by a majority of clients because it has a dedicated physical box present which takes care of memory, CPU and all such stuff. So, all your transactions happen at wire-speed.

Nginx is well suited for serving any static content - whether that be images, JS files, HTML files, CSS files, videos, etc. If you have a high-traffic website, Nginx will be a great fit because it handles large number of requests extremely efficiently. Nginx has full support on Unix systems, but only has limited support on Microsoft Windows machines.

• The foremost thing that we use DataPower is for implementing top-notch level security in different projects. We use it as a security gateway when some internal client or external client wants to make a call to any of our APIs. The basic security implementation which we do for the projects is SSL which can get more and more advanced based on the requirements of the project. Some clients want to implement OAuth, some want to implement SAML, and some are happy with a 2-way SSL handshake.
• Another big advantage of DataPower is that it supports all the major industry message formats. It especially has an inbuilt component called the Multi-Protocol Gateway which comes installed in the box itself. It's the best thing if you want to convert an XML to JSON or vice-versa. It does all those conversions at wire-speed doesn't matter the volume of those transactions. We also use it with MQ while interacting with Mainframes and legacy systems. It supports all MQ properties and gives us the flexibility to change the message as well if required.
• We have used DataPower in integration with ServiceNow as well to raise incidents and trigger emails to respective clients by writing custom scripts which continuously runs on the DataPower logs. As soon as they see any particular error for the services which are being monitored, they send an SNMP trap to ServiceNow with the error message and an incident is raised.

• 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.

• The old interface is being really missed by our team as the new WebUI interface is not that intuitive or easy to work with. It takes a lot of time to load. There should be an inbuilt wizard for creating a Rest service as well like there is for an XML based service.
• IBM support is very knowledgeable but it's not that easy to reach them. They don't release the fix patches very soon which also becomes a big issue in certain situations where critical projects are involved.
• Lastly, DataPower has its steep learning curve and it requires time and effort on your end to gain full control and make the most of the advanced features which it offers. Finding the right resource in the market is not that easy.

• Nginx often requires some initial configuration. It's worth doing, because you'll end up with great results, but it can be slightly daunting for someone to get started using it. Apache might have a leg up in that regard--When you install Apache, typically it's just about ready to do what you want already. But the issue with Apache is that most people skip the extensive tuning phase required after that, and with nginx it becomes more just a part of the configuration process.
• Sometimes, the configuration syntax, even though it's powerful and terse, isn't the most intuitive. Luckily there's plenty of documentation about what things mean and how to accomplish certain things. There may not be much that can be done about this--to have a powerful web server, you need a powerful-enough configuration language.
• The nginx brand is somewhat fragmented, and it can be confusing. There's the open source nginx web server, which I've primarily been referring to. But then there's NGINX Plus, a premium subscription-based service which works with a range of other NGINX products (NGINX WAF, NGINX Amplify, NGINX Controller). I've met a number of people who weren't very familiar with nginx, and instinctively went to nginx.com first, and from there it seems like everything costs money. It's only when they realize there's a different site, nginx.org, that they find what they went looking for.

Front end proxy and reverse proxy of Nginx is always useful. I always prefer to Nginx in overall usability when you have application server and database or multiple application servers and single database i.e. clustered application. Nginx provides really good features and flexibility which helps the system administrator in case of troubleshooting and also from the administration perspective. Also, Nginx doesn't delay any request because of internal performance issues.

Community support is great, and they've also had a presence at conferences. Overall, there is no shortage of documentation and community support. We're currently using it to serve up some WordPress sites, and configuring NGINX for this purpose is well documented.

I have found that [NGINX] seems to perform better throughout the years with less issues although I've used Apache more. I would definitely recommend [NGINX] for any high volume site and I've seen this to usually be the case from most provided web hosts who will pick [NGINX] over alternatives

• It has really taken our business to the next level. We have expanded and integrated with so many new vendors and for all those integrations DataPower is serving as our security gateway.
• We don't have to depend on any other tool for doing the load balancing of the incoming requests as that is also taken care inside the WebSphere DataPower Gateway box itself, thereby distributing the load equally.
• It has made our platform much more secure, uniform and robust to deal with any kind of incoming message format or threat as well due to its latest security mechanisms and huge processing power.

• When we first migrated our primary bidding environment architecture to Nginx, it was under duress due to Apache's inability to keep up when we consolidated away from an HAproxy model to a central HTTP proxy. So we even when we did not know what we were doing, we were able to make it work in a bad situation, and everyone was quite happy.
• The biggest complaint I have is that I find the module compilation requirements for nginx+ rather burdensome. If we pay for Nginx+, I'd love to see then have pre-built modules for ready for each release of more modules. We are spending our own time engineering an in-house solution for module testing for nginx+ releases, which is disappointing.
• I've also, as the primary Nginx person at my organization, inserted my expertise into other projects, and have saved our company lots of money getting rid of big $$$ appliances for general SSL proxying.
• Speaking of Nginx replacing SSL appliances, we had an instance where we had to suddenly enable elliptic-curve SSL ciphers and our big $$$ appliances (you know who they are), were falling over. Even their SSL accelerator cards, after all, are just a few extra cores to process SSL. But in an environment of our size, we use DNS to spread the load to hundreds of frontend proxies with dozens of cores each to spread this load out, all at a lower price than ONE of the appliance pairs running Nginx. We couldn't even tell the change in load in our Nginx architecture when we enabled the ciphers.
