Why your choice of Java Virtual Machine (JVM) matters more than ever


Tags jvm software web-development software-architecture app-development

In my recent interview with Software Daily, I discussed that there are many companies looking for better customer experience, faster execution, and lower infrastructure costs… and that they have discovered a better use of Java to help them with just that. By John Ceccarelli.

The interview describes that when you use hyper-optimized Java runtimes instead of vanilla OpenJDK – you do less tuning and debugging. This means you can build applications, data architectures or anything that needs better performance using an optimized JVM – with little or no code changes.

…there are other JVMs, like Azul Platform Prime and GraalVM, that actually do run your code differently and get better performance, carrying capacity, etc. Azul Platform Prime achieves this by taking OpenJDK, replacing key components like the JIT Compiler and the Garbage Collector, and replacing them with more optimized versions.

Many companies, when they want to look at how fast their app runs, will just do a pedal-to-the-metal throughput test that totally saturates their environment, post the top number achieved, and call it a day. But nobody runs like that in production. Instead, people say “I have an app that has a 100ms response SLA. I need to know how many instances of that app I need to provision to serve up my peak traffic of 2M requests per hour.”

So, when you’re benchmarking, you want to not look at max throughput, but max throughput you can achieve while still keeping your SLA. And you’ll find that yes, Prime can deliver higher throughput at that SLA. Follow the link to full interview to learn more!

Haskell in enterprise: Interview with Rob Harrison


Tags functional-programming software-architecture web-development app-development

We’ve all heard about Haskell success stories from famous companies like Meta and Tesla. But did you know that Haskell is successfully used in plenty of enterprises, many of which you wouldn’t think of as being at the forefront of technology? By Gints Dreimanis.

We are living through a slow period of change towards functional declarative programming and away from procedural imperative approaches. This led me to research where some of these ideas came from originally, and subsequently to discovering category theory, which I see as a beautiful and highly useful framework for thinking about software and logic and relating this to the physical world around us

Our guest is Rob Harrison, a Lead Architect at Flowmo.co. He has worked as a technical lead on projects for clients like Vodafone and Tesco. . In the interview, we’ll be talking about his experience and techniques that he uses to bring the power of functional programming to consulting projects.

What do you think is the single biggest problem in the software development industry that functional programming solves?

If I were to pick one, I’d have to say parallelisation/concurrency. It’s a recent problem really, because for much of the history of software, there was only one CPU or core to execute anything on. This fact, along with the increase in available RAM seems to be the driver towards the functional declarative style in the industry as a whole. Mental models of computing where the programmer thinks their computer is still doing one instruction at a time are really no longer valid.

From 50 ML projects, 48 made it to production within 2 weeks. How?


Tags big-data data-science cloud cio devops

Putting machine learning (ML) models in production is considered an operational challenge that is performed after all the hard work on training and optimizing the model is completed. In contrast, serverless ML starts with a minimal model, including the operational feature pipeline(s) and inference pipeline. By Jim Dowling.

In this article, we show you that writing feature pipelines and inference pipelines should not be hard and if you don’t have to configure/build the MLOps infrastructure yourself, getting to a minimal viable production model within a couple of weeks should be feasible for most models. You will learn:

  • The MVP for Machine Learning
  • 3 Programs: Feature, Training, and Inference Pipelines
  • When >90% build complete ML Systems

There is no such thing as a single machine learning pipeline - there are feature pipelines, training pipelines, and inference pipelines. And if you structure your ML systems as such, you too will be able to quickly build an end-to-end working ML system that can be iteratively improved. Good read!

Intrusion detection network – Protecting from cyber attacks


Tags infosec cloud cio miscellaneous how-to

As cyber threats continue to evolve, it’s essential for businesses to have systems in place to protect against attacks. One important tool in the cybersecurity toolkit is an intrusion detection network (IDN). By Priyanshu Sahay.

An IDN is a system that monitors a network for signs of unauthorized access or malicious activity. It does this by analyzing network traffic and looking for patterns or anomalies that could indicate an intrusion. If an IDN detects a potential threat, it can alert the system administrator or take automated action to prevent or mitigate the attack.

In this blog you will learn:

  • So, what is an IDN, and how does it work?
  • Types of Intrusion Detection Network (IDN)
  • How does a network intrusion detection system work?
  • How Intrusion Detection Network (IDN) helps from Cyber Threats?

It’s important to note that IDNs are just one part of a comprehensive cybersecurity strategy. Businesses should also consider implementing other measures, such as antivirus software, firewalls, and employee training, to help protect against cyber threats. Nice one!

NGINX tutorial: How to securely manage secrets in containers


Tags nginx infosec devops containers

Many of your microservices need secrets to operate securely. Examples of secrets include the private key for an SSL/TLS certificate, an API key to authenticate to another service, or an SSH key for remote login. Proper secrets management requires strictly limiting the contexts where secrets are used to only the places they need to be and preventing secrets from being accessed except when needed. By Robert Haynes of F5.

In this tutorial, we show how to safely distribute and use a JSON Web Token (JWT) which a client container uses to access a service. In the four challenges in this tutorial, you experiment with four different methods for managing secrets, to learn not only how to manage secrets correctly in your containers but also about methods that are inadequate:

  • Hardcode secrets in your app
  • Pass secrets as environment variables
  • Use local secrets
  • Use a secrets manager

Although this tutorial uses a JWT as a sample secret, the techniques apply to anything for containers that you need to keep secret, such as database credentials, SSL private keys, and other API keys. There is also configuration and code included together with youtube tutorial. Nice one!
