Software Infrastructure (DevOps)

IPsec

Internet Protocol Security is a set of protocols to ensure the protection of data transmitted over the Internet Protocol. Allows authentication, checks the integrity and / or encryption of IP packets. IPsec also includes protocols for secure key exchange on the Internet. Basically, the application for the organization of VPN-connections.

iptables

A user space application program, command line utility that allows to configure to set up, maintain, and inspect the Linux kernel firewall tables. With IPTables, administrators can create and modify rules that control the filtering and redirection of packages.

ITIL

IT Infrastructure Library is a library that describes the best methods of organizing the work of units or companies engaged in providing services in the field of information technology. This library describes the entire necessary set of processes to ensure the constant high quality of IT services.

JConsole

A Java graphical monitoring tool used to monitor Java Virtual Machine and Java applications, it complies to the Java Management Extensions specification. JConsole is supplied as part of the Java Development Kit (JDK).

Kerberos

A network authentication protocol that allows nodes to safely identify each other in a non-secure network. It is used to protect communication from "sniffing" tools. Kerberos can be used to encrypt all information between a client and server, not just identity.

Kernel module

A piece of code that can be loaded into the kernel demand which extends the functionality of the kernel without rebooting the system, allows the kernel to access hardware connected to the system.

Kubernetes

It is an open source platform designed to manage a cluster of Linux containers as a single system. Kubernetes manages and runs Docker containers on a large number of hosts, and also provides the co-location and replication of a large number of containers.

KVM

Kernel-based Virtual Machine is a full hardware virtualization solution that allows to create several virtual machines on one or many servers. Each virtual machine has its own virtual hardware: network cards, disk, video card and other devices.

LDAP

Lightweight Directory Access Protocol, a software protocol mostly used by medium-to-large organi­zations for accessing and maintaining directory information services over an Internet protocol network.

Linux

Unix-like operating system based on the Linux kernel, including one or another set of utilities and GNU project programs, and other components. Like the Linux kernel, systems based on it are generally created and distributed in accordance with the model of free and open source.

Linux Distributions

UbuntuDebian,  CentOS, Fedora, Gentoo, Arch, Mandriva, openSUSE, Slackware, Sabayon, Mint, Puppy, Slax, PCLinuxOS

Linux kernel

A kernel of the operating system conforming to the POSIX standards, which forms the basis of the operating systems of the Linux family. Using the Linux Kernel, lots of Linux-like operating systems were created.

Linux Server

A powerful variant of the Linux OS designed to handle requirements of business apps, web services, network administration, database management, etc. Like the Linux kernel, systems based on it are generally created and distributed in accordance with the model of free and open source.

Linux shell

A shell of Linux operating system. A command line is used to work in OS, but also a graphical module can be installed for users that don’t work with command line.

Lisp

LISt Processing language is a family of programming languages, programs and data in which are represented by linear lists of symbols. This is one of the oldest used to this day high-level programming languages, as well as the first of the extant languages to use automatic memory management.

Load Balancer

A device that acts as a reverse proxy and efficiently distributes network or application traffic across different servers. Load balancing increases concurrent user capacity and reliability of applications.

MCollective

The Marionette Collective is a management framework for server orchestration or parallel job execution. Used to synchronize changes across clusters of servers in near realtime.

Monitoring tools

New Relic, Nagios, Icinga, Graphite, Ganglia, Cacti, PagerDuty, SensuPrometheus.

MQTT

Message Queue Telemetry Transport is a subscribe, lightweight messaging protocol, designed for constrained devices and high-latency or unreliable networks. Aims to minimise network bandwidth.

MRP

Stands for Media Redundancy Protocol. It is a Media Access Control (MAC) layer data network protocol that works on most Industrial Ethernet applications. It is simple and offers faster recovery time than STP in ring network topologies.

Munin

A network and infrastructure monitoring software application used for monitoring and alerting services for servers, switches, applications, etc. Focuses on easy creating of new plugins (graphs).

Nagios

IT infrastructure monitoring tool designed to ensure systems, applications, services, and business processes are functioning properly. It can alert technical staff of the problem if it appears.

Netflix OSS

Netflix Open Source Software. A set of frameworks and libraries that Netflix wrote to solve some distributed-systems problems at scale.

Network protocols

TCP/IP (transfering data in computers and internet), HTTP (internet protocol), HTTP/2, WebSockets.

New Relic

A service for applications that includes a set of tools to monitor the performance of your applications and the stability of their work under various loads.
