I am a writer, editor, and storyteller who has written articles, software user manuals, installation instructions, social media ad copy and a lot of things in between. Below are select examples of articles I wrote for RedHat.com.
Computers designed around ARM processors and those designed around Intel or AMD are not interchangeable. There are two foundational questions that each approaches in different ways:
How do you balance transistor count and program complexity?
How do you prioritize speed, power consumption, and cost?
The answers to these questions have guided technology innovation and software development in everything from smartphones to supercomputers over the past four decades. Read more >
What's the difference between IaaS, PaaS, and SaaS? Let's start by breaking down commonality within the acroynyms. "As-a-service" generally means a cloud computing service that is provided by a third party so that you can focus on what’s more important to you, like your code and relationships with your customers. Each type of cloud computing leaves you less and less on-premise infrastructure to manage. Read more >
The state of an application (or anything else, really) is its condition or quality of being at a given moment in time—its state of being. Whether something is stateful or stateless depends on how long the state of interaction with it is being recorded and how that information needs to be stored. Read more >
Java™ frameworks are bodies of prewritten code used by developers to create apps using the Java programming language. Java frameworks are specific to the Java programming language. It’s a Java platform for developing software applications and Java programs. Read More >
A Java™ runtime environment (JRE) is a set of components to create and run a Java application. A JRE is part of a Java development kit (JDK).
A JRE is made up of a Java virtual machine (JVM), Java class libraries, and the Java class loader. JDKs are used to develop Java software; JREs provide programming tools and deployment technologies; and JVMs execute Java programs. Read More >
An image builder is a tool used in system administration to create a copy—an exact image—of a virtual system or configuration (such as an operating system, server, virtual machine [VM], container, etc.) that can then be used as a base from which developers can build and deploy these systems—or customized versions—on other machines or platforms, or in other environments. Containers and container images, for example, are used in this way to move the code needed for an application from one system or platform to another. Read More >
A software development kit (SDK) is a set of tools provided by the manufacturer of (usually) a hardware platform, operating system (OS), or programming language. Read More >
Container orchestration automates the deployment, management, scaling, and networking of containers. Enterprises that need to deploy and manage hundreds or thousands of Linux® containers and hosts can benefit from container orchestration.
Container orchestration can be used in any environment where you use containers. It can help you to deploy the same application across different environments without needing to redesign it. And microservices in containers make it easier to orchestrate services, including storage, networking, and security. Read More >
Edge computing is computing that takes place at or near the physical location of either the user or the source of the data. By placing computing services closer to these locations, users benefit from faster, more reliable services while companies benefit from the flexibility of hybrid cloud computing. Edge computing is one way that a company can use and distribute a common pool of resources across a large number of locations. Read More >
An IT migration is the shifting of data or software from one system to another. Depending on the project, an IT migration could involve one or more kinds of movement: Data migration, application migration, operating system migration, and cloud migration. Read More >
Multitenancy is a software architecture where a single software instance can serve multiple, distinct user groups. Software-as-a-service (SaaS) offerings are an example of multitenant architecture.
In cloud computing, multitenancy can also refer to shared hosting, in which server resources are divided among different customers.
Multitenancy is the opposite of single tenancy, when a software instance or computer system has 1 end user or group of users. Read More >
The Linux® kernel is the main component of a Linux operating system (OS) and is the core interface between a computer’s hardware and its processes. It communicates between the 2, managing resources as efficiently as possible.
The kernel is so named because—like a seed inside a hard shell—it exists within the OS and controls all the major functions of the hardware, whether it’s a phone, laptop, server, or any other kind of computer. Read More >
