The maincubes encyclopedia of IT, data centers and future technologies

  • Cage
    A cage can be used to segregate equipment in a data center storage area. It is a separate area where dedicated components such as racks can be stored in an access-protected environment for additional security. Cages can also be used to facilitate dedicated security, performance or capacity services.
  • Cloud
    A cloud infrastructure is an external virtual IT infrastructure providing storage space, computing resources and services. These include the use of software (SaaS), platforms (PaaS) – to develop own applications – and hardware (IaaS), including servers, storage and networking hardware.
  • Cloud connect
    A cloud connect service enables you to access several cloud providers via one single link. Single sign-in reduces costs, and the customer can take advantage of the various offerings of a range of cloud platforms.
  • Colocation
    Colocation is a process through which an organization can rent physical space and other resources within an external data center to deploy its own data center. The colocation facility often also offers an interruption-free power supply, fail-safe operation, high availability, cooling, IT security and physical security (access controls, fire protection etc.). ISO certifications and TÜV audits confirm the quality standards that the data center operator conforms to.
  • Digital factory
    Digital factories or smart factories are the highly digitized and connected production facilities at the heart of Industry 4.0. The machines at the digital factory communicate via the Internet of Things (IoT). Information technology is used to connect all phases of the production process (planning, control, maintenance etc.) so that they can be analysed and optimized.
  • Ecosystem
    In analogy to biological ecosystems, IT ecosystems consist of users that mutually benefit from each other. They exchange services and knowledge between themselves and their customers on a shared platform, creating marketplaces that everyone benefits from without incurring additional costs.
  • High-availability data center
    A data center has to minimize downtime to guarantee the interruption-free operation of IT systems. The term ‘high-availability data center’ is attributed to data centers which have a TÜV Level 3 or Tier 3 rating. These facilities guarantee 99.98 percent availability. That corresponds to a maximum downtime of 1.6 hours over a 12-month period.
  • Hybrid Cloud
    At least one private cloud (IT in your own data center or at the colocation provider) is combined with a public cloud (aws, Microsoft Azure,...) - including the corresponding integration of both cloud environments. With the public cloud, you receive exactly the IT resources you need at short notice and flexibly - and create the basis for real-time communication. For particularly high security and compliance requirements, the private cloud offers dedicated computing, storage and backup options as well as high data security.
  • Internet exchange point
    An Internet Exchange Point (IXP) is the physical infrastructure through which internet service providers and content delivery networks exchange internet traffic between their networks.
  • Internet of Things (IoT)
    The Internet of Things is the extension of internet connectivity to physical devices and everyday objects. This is achieved by incorporating microprocessors or sensors into them that connect to the internet to share data or communicate. IoT is the basis for smart factories, machine-to-machine (M2M) communication, smart cities and smart homes.
  • OCP
    The Open Compute Project (OCP) is a collaborative community which focuses on redesigning hardware technology to efficiently implement growing requirements for the infrastructure of data centers.
  • Private cloud
    A private cloud is a model of cloud computing that involves a distinct and secure cloud-based environment in which only the specified client can operate. Private clouds satisfy very high security standards since they are located in a secure environment, but they offer lower flexibility in the adaptation of procured services to needs.
  • Public cloud
    A public cloud is a mode of cloud computing in which a service provider makes resources available to the public via the internet on a fast and flexible basis. The public cloud is extremely flexible because it offers on-demand resources and you only pay for the services you use. However, open access makes it unsuitable for critical applications.
  • Rack
    In the ICT industry a rack is a server housing unit. They are generally cabinets constructed of metal to hold all the server equipment (including computer, circuit boards, hard disks etc.). A standard rack is around 2 m high, with a depth of 60 to 120 cm and a width of 60, 70 or 80 cm.
  • Secure mobility
    In the future we will be using connected cars, self-driving cars, e-mobility and connected traffic control systems. Secure mobility services ensure that the enormous quantities of data being shared between mobile devices (smartphones, digital assistants, connected cars etc.) are managed in a secure ecosystem environment.
  • Smart city
    Smart cities are municipalities that use digital technology for efficient traffic management systems, smart parking, direct access to local amenities and optimized energy efficiency. All the services are connected via a secure ecosystem and offer added value to residents and visitors.
  • Suite
    A suite is an IT room dedicated to one specific customer: a ‘data center within a data center’. It offers far higher security against unauthorized access than a cage and allows for the customer-specific installation of power and network components.
  • Vendor lock-in
    Vendor lock-in is a situation in which a customer using a product or service cannot easily transition to a competitor’s product or service (e.g. due to contractual constraints or proprietary technologies that are incompatible with those of competitors). The customer is deterred from switching over to another provider or system because it appears to be associated with higher costs than remaining with the existing one.
