The Capability Maturity Model (CMM) is a development model created in 1986 after a study of data collected from organizations that contracted with the U.S. Department of Defense, who funded the research. The term "maturity" relates to the degree of formality and optimization of processes, from ad hoc practices, to formally defined steps, to managed result metrics, to active optimization of the processes.
Capability Maturity Model Integration (CMMI) is a process level improvement training and appraisal program. Administered by the CMMI Institute, a subsidiary of ISACA, it was developed at Carnegie Mellon University (CMU). It is required by many U.S. Government contracts, especially in software development. CMU claims CMMI can be used to guide process improvement across a project, division, or an entire organization.
This article presents a comparison of the features, platform support, and packaging of many independent implementations of Domain Name System (DNS) name server software.
In computing, virtualization is the use of a computer to simulate another computer. The following is a chronological list of virtualization technologies.
RabbitMQ is an open-source message-broker software that originally implemented the Advanced Message Queuing Protocol (AMQP) and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol (STOMP), MQ Telemetry Transport (MQTT), and other protocols.
OpenShift is a family of containerization software products developed by Red Hat. Its flagship product is the OpenShift Container Platform — a hybrid cloud platform as a service built around Linux containers orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux. The family's other products provide this platform through different environments: OKD serves as the community-driven upstream, Several deployment methods are available including self-managed, cloud native under ROSA, ARO and RHOIC on AWS, Azure, and IBM Cloud respectively, OpenShift Online as software as a service, and OpenShift Dedicated as a managed service.
Kubernetes is an open-source container orchestration system for automating software deployment, scaling, and management. Originally designed by Google, the project is now maintained by a worldwide community of contributors, and the trademark is held by the Cloud Native Computing Foundation.
Mirantis Inc. is a Campbell, California, based B2B open source cloud computing software and services company. Its primary container and cloud management products, part of the Mirantis Cloud Native Platform suite of products, are Mirantis Container Cloud and Mirantis Kubernetes Engine. The company focuses on the development and support of container and cloud infrastructure management platforms based on Kubernetes and OpenStack. The company was founded in 1999 by Alex Freedland and Boris Renski. It was one of the founding members of the OpenStack Foundation, a non-profit corporate entity established in September, 2012 to promote OpenStack software and its community. Mirantis has been an active member of the Cloud Native Computing Foundation since 2016.
ProGet is a package management system, designed by the Inedo software company. It allows users to host and manage personal or enterprise-wide packages, applications, and components. It was originally designed as a private NuGet manager and symbol and source server. Beginning in 2015, ProGet has expanded support, added enterprise grade features, and is targeted to fit into a DevOps methodology. Enterprises utilize ProGet to “package applications and components” with the aim of ensuring software is built only once, and deployed consistently across environments.
Technology readiness levels (TRLs) are a method for estimating the maturity of technologies during the acquisition phase of a program. TRLs enable consistent and uniform discussions of technical maturity across different types of technology. TRL is determined during a technology readiness assessment (TRA) that examines program concepts, technology requirements, and demonstrated technology capabilities. TRLs are based on a scale from 1 to 9 with 9 being the most mature technology.
Borg is a cluster manager used by Google since 2008 or earlier. It led to widespread use of similar approaches, such as Docker and Kubernetes.
Container Linux is a discontinued open-source lightweight operating system based on the Linux kernel and designed for providing infrastructure for clustered deployments. One of its focuses was scalability. As an operating system, Container Linux provided only the minimal functionality required for deploying applications inside software containers, together with built-in mechanisms for service discovery and configuration sharing.
gVisor is a container sandbox developed by Google that focuses on security, efficiency and ease of use. gVisor implements around 200 of the Linux system calls in userspace, for additional security compared to Docker containers that run directly on top of the Linux kernel and are isolated with namespaces. Unlike the Linux kernel, gVisor is written in the memory-safe programming language Go to prevent common pitfalls which frequently occur in software written in C.
TiDB is an open-source NewSQL database that supports Hybrid Transactional and Analytical Processing (HTAP) workloads. Designed to be MySQL compatible, it is developed and supported primarily by PingCAP and licensed under Apache 2.0. It is also available as a paid product. TiDB drew its initial design inspiration from Google's Spanner and F1 papers.
The Cloud Native Computing Foundation (CNCF) is a Linux Foundation project that was started in 2015 to help advance container technology and align the tech industry around its evolution.
Teleport is an open-source tool for providing zero trust access to servers and cloud applications using SSH, Kubernetes and HTTPS. It can eliminate the need for VPNs by providing a single gateway to access computing infrastructure via SSH, Kubernetes clusters, and cloud applications via a built-in proxy.
Open Service Mesh (OSM) was a free and open source cloud native service mesh developed by Microsoft that ran on Kubernetes.
Azure Linux, previously known as CBL-Mariner, is a free and open-source Linux distribution that Microsoft has developed. It is the base container OS for Microsoft Azure services and the graphical component of WSL 2.
eBPF is a technology that can run programs in a privileged context such as the operating system kernel. It is the successor to the Berkeley Packet Filter filtering mechanism in Linux and is also used in non-networking parts of the Linux kernel as well.
