Software Infrastructure (DevOps)

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.

Ubuntu

Developed by the community, based on the Linux kernel operating system, which is ideal for use on personal computers, laptops and servers. It contains all the necessary programs that you need: an Internet browser, an office suite for working with texts, programs for communicating on the Internet and many others.

Ubuntu Juju

A universal modelling tool from Ubuntu, used for application oriented deployments, allows to deploy, configure, manage, maintain, and scale cloud applications quickly and efficiently on public clouds, as well as on physical servers, OpenStack, and containers.

UDP

User Datagram Protocol that allows computer applications to send messages (in this case referred to as datagrams) to other hosts over an IP network without the need for a prior message to set up special transmission channels or data paths.

UNIX

Family of portable, multitasking and multi-user operating systems. The ideas behind UNIX had a huge impact on the development of computer operating systems. Currently, UNIX-systems are recognized as one of the most historically important OS.

VCP-DCV

Stands for VMware Certified Professional - Data Center Virtualization certification. It validates candidate skills to implement, manage, and troubleshoot a vSphere V6.7 infrastructure, using best practices to provide a powerful, flexible, and secure foundation for business agility that can accelerate the transformation to cloud computing.

Virtualization

A tool for organizing several virtual computers on one real computer. In sum all the resources of virtual computers are equal to the resources of one real computer. Each virtual computer can have its own OS and perform its tasks without interfacing with others.

Virtualization tools

VMware, Xen, KVM, OpenStack, Hyper-V, Azure Pack, Docker, OpenVZ, VirtualBox, Parallels Desktop, Vagrant.

VLAN

Stands for "Virtual Local Area Network," or "Virtual LAN." A VLAN is a custom network created from one or more existing LANs. It enables groups of devices from multiple networks (both wired and wireless) to be combined into a single logical network.

VPN

Virtual Private Network is a network technology that creates a secure network connection over a public network such as the Internet or a private network owned by a service provider.

VRRP

Stands for Virtual Router Redundancy Protocol. VRRP is a standard Internet protocol (IP) that can be used for creating a virtual gateway or for load balancing. It allows a backup router for a statistically configured one on a local area network (LAN), in case it fails.

VxWorks

A real-time operating system (RTOS) designed for use in embedded systems. Used to control network and communication devices, test and measurement equipment, computer peripherals, automotive systems, avionics equipment, and diverse consumer products.
