Improving Performance in Enterprise Web Applications

Zach Gardner Opinion, Programming

Every team that builds a large web application can generally pick from the following: delivering application functionality on time, with high quality, or high performance. Teams can pick one or two of the options, but they can’t pick all three.

Most teams opt to only focus on performance if and when it becomes a problem. This, unfortunately, can be far too late for some projects. Anyone who has been in the industry can empathize with both sides of the equation – choosing to defer performance concerns, as well as seeing the negative impact it can have on the success of the product as a whole.

It is a lesson I’ve learned from hard experience, so I want to make sure others can learn from my mistakes. In this post, I suggest a handful of principles that help to find a happy medium for delivering high-quality software applications while focusing on performance.

Significant improvements can be realized even if only one or two of the principles are applied. Applying all of them, of course, will produce the best results.

Security in the Microservices Paradigm

Zach Gardner Architecture, Microservices Leave a Comment

One of the least glamorous aspects of implementing a Microservices architecture is the security. It’s not fun or cool when compared to things like the circuit breaker or service discovery, yet it is a critical piece of the ecosystem especially in an enterprise setting.

I’m working on a large Microservices project for a healthcare enterprise on the East Coast. One of the first pieces of the infrastructure we assisted with was security, which has turned out to be a lifesaver for everything that has come after it. I was able to see what security works well as well as what does not work so well in a Microservices environment. In this blog post, I will share a medium to high-level look into how security can be implemented in Microservices.

Docker: VMs, Code Migration, and SOA Solved

Zach Gardner DevOps, Docker, Technology Snapshot 1 Comment
