Access

What do they mean with Ubiquitous Access?
Ubiquitous Access represents one of the essential characteristics that Cloud Computing must meet. It stands for widely available network access. You do not have to meet very specific and special requirements to gain access, the services in the cloud are available via networks such as the internet. The device used should also not matter, available via desktop, mobile, tablet, etc. And you can assume that the various clients such as Windows, Mac, iPad and Android systems are all flawlessly supported.

Ansible

What is Ansible in cloud computing?
Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, application deployment, intraservice orchestration, and provisioning. Due to the current wishes and need to be able to scale quickly, IT environments are nowadays very complex and automation is desired because it is simply no longer possible to do it manually.

API

What is an API? How do Api's work? 
Application Programming Interfaces make it possible to exchange data easily and securely. An API is a kind of software intermediary that allows two applications to talk to each other. An API takes care of all interactions between applications, data and devices and enables transfer between systems. For example, you want to see what the stock of a product is at a webshop, you look at the website and the API of the webshop shows all the information you have checked from the database, without you having direct access to the database. An API is a set of instructions or code, these sets make it possible to reuse or combine code, making it easier to develop new programs.

API Endpoints

What are API Endpoints and what are they doing?
An API works with requests and responses, the place where an API sends the request and the place of the source is called an endpoint. So the contact points of communication channels are considered endpoints, the user requests, the API processes, and the API endpoint provides a response. Like a waiter in a restaurant takes your order, passes it on to the kitchen (they prepare it) and brings the dish back to your table.

Backup

What is a backup?
You make a backup of important data, not systems but the files such as documents, photos and music. If you lose data, you can retrieve it from your backup. With a backup you can restore a single file and you don't have to restore everything, like with a snapshot.
You can also look at our tutorial with Arq: https://docs.fuga.cloud/automated-back-up

Block storage

What is block storage?
Block storage is the technology used to store data files on SANs (Storage Area Networks) or in the cloud. With block storage, the data is split into blocks and then stored separately from each other, each with a unique identifier. Each storage volume can be thought of as an independent disk and provides raw storage capacity of a fixed size. This block can be mounted as if it were a physical disk and controlled by a server operating system.

CiC

What does CiC mean? What is CiC doing?
The dutch Cloud Infrastructure Coalition, a number of Dutch cloud organisations, of which Fuga Cloud is one, have united to bring the Dutch expertise to the forefront within GAIA-X. You can also read our blog: https://fuga.cloud/labs/gaia-x/

CLI

What is CLI? What can you do with CLI?
Command Line Interface, is a text-based interface used for entering commands and returning the answer in the same form. The detailed control and the high level of functionality allow for greater user flexibility. You can often do things via CLI that are impossible or difficult with a GUI.

Cloud

What do the mean with the Cloud?
An online environment, where you can store data but also work. Working in the cloud is  also called cloud computing.

How did the cloud symbol got created?
The cloud as a symbol stems from the Packet Switching concept. The trajectory that data packets traveled during transmission was released. Because that route was no longer recorded, known or important, a cloud was drawn.

Cloud Computing

What is Cloud Computing?
All software, platforms and data are hosted on external servers. So you do not physically own a data center or server, but purchase it from a cloud provider. The advantage of this is that you can use all the computing power, storage and databases you need (and often upscaling or downsizing within a few clicks), without having to take care of maintenance.

Cloud Service Provider

What is a Cloud Service Provider?
A company that offers a platform, infrastructure, storage of data, or use of applications in various forms online for a fee. Scalability according to the needs of these services and only paying for what one uses are the biggest advantages of this form of cloud computing.

Cloud Storage

What is Cloud Storage?
Cloud Storage refers to online space that is used to store data (data, software, photos, music etc) instead of an (external) hard drive from a computer. This makes it possible to also have this data available via other devices.

Clusters

What are clusters in computing?
With server clustering, reference is made to a group of servers that work together on one system in order to provide higher availability to the users. A server takes over tasks from a failed server in the event of a failure, thus preventing downtime or complete failure. This group of servers is connected to one system.

Community of Multicloud

What do they mean with Community of Multicloud?
If several organisations have the same or comparable requirements for the cloud and trust each other, they can share a cloud together. This equates the design and privacy with a private cloud, but has the advantages of a public cloud when it comes to scalability and cost savings. A concrete example is the cooperation of different municipalities. They process a lot of personal data and therefore place high demands on confidentiality and security. A public cloud cannot provide that, so one should opt for a private cloud. By placing all municipalities within the same infrastructure, you avoid setting up the same cloud several times, so you have a nice cost saving per municipality.

A container is a package of all necessary software and elements to virtualise an operating system. This allows a container to run in any environment, from laptop to public cloud or private data center.

CPU

What is a CPU and what are CPU's doing?
Central Processing Unit or processor, is part of a compute server. The CPU is the so-called brain of a computer, this part is responsible for the execution of computer programs, the calculations and instructions of a program. It is an important link for communication between the various system resources such as memory, disks and peripherals.

Credentials

What are credentials in cloud computing?
Credentials or Credentials refer to the verification of an identity or tools for authentication. They can be part of a certificate or other authentication process that helps confirm a user's identity with respect to a network address or other system ID.

GPU

What is a GPU and how are GPU's working?
A Graphics Processing Unit is a specialised processor originally designed to speed up graphics rendering. Also called graphics card or video card. The GPU performs fast calculations and therefore makes the CPU available to do other things. Because a GPU can process a lot of data at once, they are also very useful for machine learning, video editing and gaming.

GUI

What does GUI mean?
GUI stands for Graphical User Interface, the interface that communicates with a device through graphical icons and audio indicators. So you click on an icon to start a program instead of typing a command like with CLI.

Hybride

What does hybride mean in computing?
Simply put, this is a combination of one or more public or private clouds. The infrastructures continue to operate separately from each other, but they do exchange data and/or applications with each other. So you can store part of it in a private cloud (the sensitive information or business applications), while a SaaS application such as Sharepoint is also used. As an end user, you don't notice this separation because you only have to log in once and the exchange is all arranged under water.

Hypervisor

What is a hypervisor in computing?
A hypervisor is the computer software or hardware that makes it possible to create and manage virtual servers. This allows multiple virtual computer systems (guests) to run simultaneously and independently of each other on one physical system (host). The virtual servers share the host's system resources, such as internal memory, compute power, and disk space, and can each run a different operating system.
