PHP is a fast scripting language that is ubiquitous with web development. WordPress uses the language as it’s core interface for developers to enhance the platform. It’s relatively easy to learn and is well supported by the development community. While PHP helps developers create web applications quickly, there is no development environment associated with the language. By contrast, a development …
Intro to managing and running a containerized Java Spring Boot application Docker is a platform for packaging, deploying, and running applications in containers. It can run containers on any system that supports the platform: a developer’s laptop, systems on “on-prem,” or in the cloud without modification. Images, the packages Docker uses for applications, are truly cross-platform. Java microservices are a …
Dependency injection is a programming technique that makes a class independent of its dependencies. It achieves that by decoupling the usage of an object from its creation. This helps you to follow SOLID’s dependency inversion and single responsibility principles. As I explained in my previous articles about the SOLID design principles, their goal is to improve the reusability of your …
Today’s post is a detailed guide on how to send custom metrics to AWS CloudWatch monitoring using AWS Lambda. Starting from scratch, we’re going to finish up this post by leaving a serverless project running on Amazon Web Services (AWS). And do you want to hear the best part? Getting started will cost you less than you might spend on a …
While we all started to learn how to code with HTML, developing a sophisticated app requires a more advanced language. Java and Python are two of the hottest programming languages in the market right now because of their versatility, efficiency, and automation capabilities. Both languages have their merits and their flaws, but the main difference is that Java is statically …
The service locator pattern is a relatively old pattern that was very popular with Java EE. Martin Fowler described it in 2004 on his blog. The goal of this pattern is to improve the modularity of your application by removing the dependency between the client and the implementation of an interface. Interfaces are one of the most flexible and powerful …
GitHub has become the gold standard platform for sharing code with everyone from the person sitting next to you to a developer on the other side of the world. As a team or product grows, so does its need for organizational structure and security. But even if your project or group of collaborators is small, you’ll learn that GitHub’s robust …
Azure has plenty of services for hosting your applications and their components. It also has extensive options for deploying to these services. Barry Luijbregts introduces four of the primary options for hosting apps in his article, “Which Azure Deployment Model Should You Use? 4 Ways to Deploy.” In that post, Luijbregts covers where to deploy on Azure; in this post, I’m …
A chatbot is an application that simulates a human responding to the user. It’s a more natural way to interact with a system by using conversation. Let’s say, for example, that you want to order a pizza. Instead of wasting your time tapping randomly or searching the Internet to figure out how to use the app, you could just start …
In recent years Continuous Delivery (CD) has become the standard choice for DevOps teams looking to develop and deploy high quality code. However as teams grow larger and take on more ambitious tasks, the implementation of CD—the actual delivery in Continuous Delivery—can be a challenge. Delays happen for a number reasons, and DevOps teams are consistently battling to keep projects …
The coding process is like an amusement park– it involves a number of variables and safety considerations to ensure the quality of each ride. There’s a lot that can go wrong if the nuts and bolts of the process aren’t planned well in advance. Whether you’re building a web application or a roller coaster, the key to satisfying customers is …
Design patterns provide a reliable and easy way to follow proven design principles and to write well-structured and maintainable code. One of the popular and often used patterns in object-oriented software development is the adapter pattern. It follows Robert C. Martin’s Dependency Inversion Principle and enables you to reuse an existing class even so it doesn’t implement an expected interface. …
Stackify, a leader in application performance tools, is excited to announce App Scoring as part of the Retrace product suite. App Scoring expands on Retrace’s deep performance insights, combining many factors of an application’s performance into a single “letter grade” benchmark score. With the addition of this new metric, users of Retrace can now see at a glance how their …
Over the last few years, people have increasingly been adopting containers. But to use containers at a large scale, you need to use an orchestrator to ease the administration of your applications. Kubernetes is the most popular orchestrator and, while there are many concepts you need to learn to make the most of it, the benefits of using Kubernetes are …
For Agile and DevOps teams trying to move the needle of progress, CI/CD has become the gold standard. High-performing teams are “shifting left” by automating more and more steps of the software development lifecycle. CI/CD helps teams deliver more value to customers faster by removing manual processes and minimizing human error. However, Agile and DevOps teams continue to fall short …
Every time we need to deploy to production, we worry about how changes will affect the user experience. No matter what technique or strategy you use to make deployments, there are going to be times when the things that can go wrong will go wrong. It’s Murphy’s law. The fact of the matter is you can’t always prevent errors when …
When developing an application, chances are that it won’t perform as expected on the first run. In order to check what went wrong, developers in general use debuggers. But experienced developers know that if it happens in production, most debuggers won’t be available. Hence, they pepper the source code with logging statements to help their future self debug the next …
As cloud becomes the norm, we’re letting others manage much of our infrastructures for us. Cloud providers offer common metrics like CPU, memory, storage, and networking so that you can stay up to date on the health of your system. And we worry less and less about those metrics with serverless architectures. But there remains a major concern that we …
DevOp teams are increasingly looking toward Kubernetes as a scalable and effective way to package application containers of all sorts.. However, while Docker and Kubernetes have paved the way for the container and microservices revolution, there is still plenty of room for innovation. The strength of the Kubernetes tool lies in its ability to blend the simplicity of Platform as …
