Improving Performance in Enterprise Web Applications

Zach Gardner Articles, 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.

Into the Core

The client Iโ€™m currently assisting has begun to move applications from more monolithic architecture into a more modern, cloud-based architecture. The organization is a bit of a .NET anomaly in that it is a company thatโ€™s primarily Java, yet has some .NET.

So even though Microsoft has a list of framework tools (such as Azure Service Fabric and Azure App Service), itโ€™s fair to say that asking a primarily Java-focused company to use those tools could be an uphill battle. This is where .NET Standard and .NET Core have come to the rescue.

I work with a ton of smart people and Iโ€™m pretty amazed at how fast they can pick up on things from reading. I, however, cannot really understand it fully until I touch it. So letโ€™s build a quick RESTful Web API step by step to see how challenging it is. Weโ€™ll be using .NET Standard, .NET Core, and ASP.NET Core.

Case Study Published – Blockchain In Hyperledger: Better Than ETL?

Keyhole Software Articles, Blockchain, Java Leave a Comment

In general terms, a blockchain is an immutable transaction ledger in a distributed network of participating peers. Its data includes a string of transaction records secured with cryptography. Benefits of blockchain can include decentralization, immutability, provenance, and finality.

While Bitcoin and Ethereum cryptocurrencies brought blockchain to the forefront of technology headlines, the technology underneath has true potential value for the enterprise outside of the cryptocurrency space. The features provided by blockchain technology can lead business benefits like lower costs, higher efficiency, and lower risk. Seeing a technology actually applied reinforces understanding. It can also be a genesis for new ideas.

In this case study, we walk through a Hyperledger Fabric reference blockchain with a focus on showing the potential value for enterprise-level organizations.

The potential cost savings of blockchain is one of the benefits not really discussed as a whole. However, we at Keyhole believe it could be a significant feature benefit. The goal of this case study is to help reinforce this…

Have You Plunkโ€™d Lately?

More than once as a developer, Iโ€™ve come across the need to quickly prototype an idea or solution. This generally involves making a special project with all the necessary local parts, then going in and making the prototype. Doing this takes time and effort for something which in the end will probably just be throwaway code. Luckily Iโ€™ve now found a better way.

โ€œPlunkerย is a tool to prototype, experiment, share and debug your ideas on the web platform. From idea to implementation, Plunker helps you build something quickly and frictionlessly.โ€

Iโ€™ve found Plunker to be a great tool to use when I quickly need to test out an idea or solution. I no longer have to go through the process of creating a whole application locally just to see if I can do a loop with some data or something else just as simple. Now I can simply choose a template from Plunker, and I can get down to business.

In this blog I will introduce Plunker, showing how to use it to quickly create and edit an Angular startup project…
