Software Infrastructure (DevOps)

Shell script

A command-line interpreter, contains a sequence of commands for a Unix-based operating system, usually created for command sequences for which a user has a repeated need.

SIP

Session Initiation Protocol is a telephony signaling protocol used in VoIP communications for initiating an interactive user session that involves multimedia elements such as video, voice, chat, gaming, virtual reality, mostly used for free.

Site Reliability Engineering

Site Reliability Engineering is a discipline that incorporates aspects of software engineering and applies them to infrastructure and operations problems. The main goals are to create scalable and highly reliable software systems.

SmartOS

SmartOS is an open-source operating system based on the Illumos project, designed for cloud computing, virtualization, and containerization.

SMB

Stands for Server Message Block. It is an internet protocol for the application layer, used for shared printer, files and serial ports access. SMB is usually involved in client-server communication on  Microsoft Windows computers.

SMP

Symmetric Multiprocessing is an architecture of multiprocessor computers in which two or more identical processors of comparable performance are connected uniformly to the shared memory and perform the same functions. 

SMTP

Simple Mail Transfer Protocol is a TCP/IP protocol used in sending and receiving emails, usually used with one of POP3 or IMAP, allows users save messages in a server mailbox and download them from the server.

SNMP

Stands for Simple Network Management Protocol. An application-layer protocol designed for monitoring and managing network devices, such as routers, switches and wi-fi connected devices, and their functions. SNMP uses one or more manager-computers to oversee the devices via an agent, a software program that feeds information to managers.

Software installations and upgrades

Software installation refers to the particular configuration of a software or hardware with a view to making it usable with the computer. Software upgrade refers to any major upgrade to the software that adds significant or completely new changes to the program.

Solaris

An Unix-based operating system that was developed for the SPARC platform, since 2010, belongs together with Oracle's Sun assets. Despite the fact that Solaris is an operating system with closed source code, most of it is open and published in the OpenSolaris project.

Solus

An independent Linux distribution that uses Budgie as the desktop environment and Eopkg for package management. Solus - an operating system for modern PCs, the main purpose of which is convenience in use. The operating system is built from scratch and does not depend on any other distributions.

SPDY

An open networking protocol which main objective is to reduce the time it takes to load web pages and their elements. This is achieved by prioritizing and multiplexing the transfer of multiple files in such a way that only one connection is required for each client.

Spring Cloud

A collection of tools that provides solutions to commonly encountered patterns while building distributed systems, simplifies development of JVM apps for the cloud.

SQS

Amazon Simple Queue Service. Provides the ability to decouple and scale microservices, distributed systems, and serverless applications.

SSH

Secure Shell is a network protocol that provides administrators with a secure way to access a remote computer (for example remote login to computer systems by users). Uses a public-key cryptography to authenticate computer.

SSIS

SQL Server Integration Services is a Microsoft SQL Server DBMS component that can be used to perform a wide range of data migration tasks. This tool can also be used to automate the servicing of SQL Server and to update multidimensional OLAP cubes.

SSL

Secure Sockets Layer is a technology for establishing an encrypted link between a server and a client. The SSL certificate begins to encrypt any data that comes from the client computer to your server. At the same time, the usual link in the HTTP browser turns into HTTPS, where "s" means secure-protected.

STP

Stands for Spanning Tree Protocol. It is used for preventing bridge loops and their side effects in Ethernet local area networks. STP also allows backup links and corrects network changes or failures in case redundant loops were purposely planted in a network.

SunOS

A Unix-branded operating system developed by Sun Microsystems for their workstation and server computer systems. Usually, the SunOS name is used to refer to versions 1.0 to 4.1.4, which were based on BSD; versions 5.0 and later are based on UNIX System V Release 4, and are marketed under the brand name Solaris.

System administration

System administration refers to the management of one or more hardware and software systems.

System engineering

Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles.

TCP

Transmission Control Protocol is one of the main protocols for the transmission of Internet data, designed to control the transfer of data. Networks and subnets that share TCP and IP protocols are called TCP / IP networks.

TCP/IP

Transmission Control Protocol/Internet Protocol is a suite of communications protocols used to interconnect hosts on the Internet. These protocols are used for connection two or more computers via the internet for data transferring.

Terraform

A tool used to create, change and improve production infrastructure. It codifies APIs into declarative configuration files which can be shared amongst team members, treated as code, edited, reviewed, and versioned.

TLS

Transport Layer Security is a cryptographic protocol that enables secure communications over a computer network between the web server and the connected browser. Its predecessor is SSL.
