Kubernetes
Kubernetes (), also known as K8s is an open-source software, open-source OS-level virtualization, container orchestration (computing), 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. The name ''Kubernetes'' originates from the Greek language, Greek κυβερνήτης (kubernḗtēs), meaning 'governor', 'helmsman' or 'pilot'. ''Kubernetes'' is often abbreviated as ''K8s'', counting the eight letters between the ''K'' and the ''s'' (a numeronym). Kubernetes assembles one or more computers, either virtual machines or bare machine, bare metal, into a Computer cluster, cluster which can run workloads in containers. It works with various container runtimes, such as containerd and Cloud Native Computing Foundation#CRI-O, CRI-O. Its suitability for running and managing workloads of ...

Open Container Initiative
The Open Container Initiative (OCI) is a Linux Foundation project, started in June 2015 by Docker, CoreOS, and the maintainers of appc (short for "App Container") to design open standards for operating system-level virtualization (containers). At launch, OCI was focused on Linux containers and subsequent work has extended it to other operating systems. Specifications There are currently three OCI specifications in development and use: the ''Runtime Specification'' (runtime-spec), the ''Image Specification'' (image-spec), and the ''Distribution Specification'' (distribution-spec). The OCI organization includes the development of runc, which is the reference implementation of the runtime-spec, a container runtime that implements their specification and serves as a basis for other higher-level tools. runc was first released in July 2015 as version 0.0.1 and it reached version 1.0.0 on June 22, 2021. The OCI Image Format Project was split out from the Runtime Project into its own ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horizontal Scaling
Scalability is the property of a system to handle a growing amount of work. One definition for software systems specifies that this may be done by adding resources to the system. In an economic context, a scalable business model implies that a company can increase sales given increased resources. For example, a package delivery system is scalable because more packages can be delivered by adding more delivery vehicles. However, if all packages had to first pass through a single warehouse for sorting, the system would not be as scalable, because one warehouse can handle only a limited number of packages. In computing, scalability is a characteristic of computers, networks, algorithms, networking protocols, programs and applications. An example is a search engine, which must support increasing numbers of users, and the number of topics it indexes. Webscale is a computer architectural approach that brings the capabilities of large-scale cloud computing companies into enterprise ...

Public Key Infrastructure
A public key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The purpose of a PKI is to facilitate the secure electronic transfer of information for a range of network activities such as e-commerce, internet banking and confidential email. It is required for activities where simple passwords are an inadequate authentication method and more rigorous proof is required to confirm the identity of the parties involved in the communication and to validate the information being transferred. In cryptography, a PKI is an arrangement that ''binds'' public keys with respective identities of entities (like people and organizations). The binding is established through a process of registration and issuance of certificates at and by a certificate authority (CA). Depending on the assurance level of the binding, this may be carried out by an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OAuth
OAuth (short for open authorization) is an open standard for access delegation, commonly used as a way for internet users to grant websites or applications access to their information on other websites but without giving them the passwords. This mechanism is used by companies such as Amazon, Google, Meta Platforms, Microsoft, and Twitter to permit users to share information about their accounts with third-party applications or websites. Generally, the OAuth protocol provides a way for resource owners to provide a client application with secure delegated access to server resources. It specifies a process for resource owners to authorize third-party access to their server resources without providing credentials. Designed specifically to work with Hypertext Transfer Protocol (HTTP), OAuth essentially allows access tokens to be issued to third-party clients by an authorization server, with the approval of the resource owner. The third party then uses the access token to access th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prometheus (software)
Prometheus is a free software application used for event monitoring and alerting. It records metrics in a time series database (allowing for high dimensionality) built using an HTTP pull model, with flexible queries and real-time alerting. The project is written in Go and licensed under the Apache 2 License, with source code available on GitHub. History Prometheus was developed at SoundCloud starting in 2012, when the company discovered that its existing metrics and monitoring tools (using StatsD and Graphite) were insufficient for their needs. Specifically, they identified needs that Prometheus was built to meet, including a multi-dimensional data model, operational simplicity, scalable data collection, and a powerful query language, all in a single tool. The project was open-source from the beginning and began to be used by Boxever and Docker users as well, despite not being explicitly announced. Prometheus was inspired by the monitoring tool Borgmon used at Google. B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microservices
In software engineering, a microservice architecture is an architectural pattern that organizes an application into a collection of loosely coupled, fine-grained services that communicate through lightweight protocols. This pattern is characterized by the ability to develop and deploy services independently, improving modularity, scalability, and adaptability. However, it introduces additional complexity, particularly in managing distributed systems and inter-service communication, making the initial implementation more challenging compared to a monolithic architecture. Definition There is no single, universally agreed-upon definition of microservices. However, they are generally characterized by a focus on modularity, with each service designed around a specific business capability. These services are loosely coupled, independently deployable, and often developed and scaled separately, enabling greater flexibility and agility in managing complex systems. Microservices architec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Service Mesh
In software architecture, a service mesh is a dedicated infrastructure layer for facilitating service-to-service communications between services or microservices using a proxy. A dedicated communication layer can provide numerous benefits, such as providing observability into communications, providing secure connections, and automating retries and backoff for failed requests. A service mesh consists of network proxies paired with each service in an application and a set of task-management processes. The proxies are called the data plane and the management processes are called the control plane. The data plane intercepts calls between different services and processes them; the control plane is the brain of the mesh that coordinates the behavior of proxies and provides APIs for operations and maintenance personnel to manipulate and observe the entire network. The service mesh architecture is implemented by software products such as Istio, Cilium, Linkerd, Consul, AWS App Mes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
