A data center is a central location where data and information are physically stored on IT hardware. Often, companies operate their IT hardware in their own server room. However, due to space requirements, increasing performance, and heightened security demands, many companies prefer colocation, also known as server hosting. In the context of colo, the company's own servers are located in an external data center, where they are professionally hosted. The accommodation of servers can be in height units (U), racks, a private cage, or an entire suite. Data centers also offer a wide range of additional services such as data recovery, cloud storage, or server hosting.

Colocation (short Colo) means housing IT infrastructure – particularly servers – in a professional external data center instead of hosting them internally within the company. The colocation data center provides the necessary infrastructure such as power supply, cooling, or network connectivity and guarantees the security of the servers. The customer usually remains the owner of the server components but can also rent them from the data center. The advantages of colocation services are primarily reduced costs and increased security.

Cloud Storage refers to the provision of storage space for data over the Internet. Instead of using physical storage devices locally, data is stored in external data centers on cloud servers and made accessible over the network. This allows users to access their data from anywhere and from various devices as long as there is an internet connection. For customers who prefer to store their sensitive data securely, reliably, and cost-effectively in a physical way, colocation in a colocation data center is an option.

A cloud server is a virtual server that is hosted in an external data center and made accessible over the internet. These cloud servers utilize the resources of a network of physical servers to provide computing resources such as processing power, storage, and network functions. Cloud servers offer scalability and flexibility, as they allow customers to use and pay for resources as needed. Alternatively, there are also colocation servers, which are also flexibly scalable, cost-effective, and physically secure.

Data recovery, also known as data restoration, refers to the recovery of lost or damaged data stored on servers and other storage systems of the data center. Data centers use specialized techniques and tools to ensure data integrity and enable access to critical data, even in cases of hardware failures or other disruptions. Data recovery is thus an integral part of the security and data management strategy of every data center to ensure the reliability and continuity of the IT infrastructure and to minimize data loss.

cf. Data Recovery

Disaster recovery refers to the planned approach for restoring IT infrastructure and business-critical systems after a severe failure or disaster. This includes the implementation of backup and recovery processes as well as the provision of redundancy and failover mechanisms to maintain operations despite a disaster or to restore them as quickly as possible. An effective disaster recovery plan minimizes downtime, protects data integrity, and ensures business continuity, even under extreme conditions such as natural disasters, cyberattacks, or hardware failures.

Data protection refers to measures and technologies aimed at ensuring the security, integrity, and availability of sensitive data. This includes security precautions such as encryption, access control, authentication, and monitoring to protect data from unauthorized access, theft, manipulation, or loss. Physical security plays a crucial role in this. The division into security zones, modern access and monitoring systems, as well as resilient facilities and measurement systems for early detection of dangers are important factors in protecting sensitive data.

Backup Cloud refers to a service where data is copied from a local storage location or another data center to the cloud to protect it from data loss and ensure availability in the event of a failure. By using Backup Cloud services, companies can redundantly secure their data to protect against hardware failures, natural disasters, human error, or malicious attacks. Backup cloud services are usually part of a disaster recovery strategy for companies and data centers.

Server hosting refers to a service where companies outsource and operate their IT infrastructure – particularly their servers – in an external data center. This allows customers to benefit from the technologies, protection and security measures, as well as the expertise of the data center provider, without bearing the costs and challenges of managing their own infrastructure. In particular, colocation presents itself as a concept to securely store and manage sensitive data.

When renting a server, customers of data centers can rent dedicated server resources from a data center provider instead of purchasing and operating physical servers. Renting servers allows customers access to high-quality hardware, powerful network infrastructure, and professional support without bearing the capital expenditures and operating costs for purchasing, maintaining, and upgrading their own servers.

Data storage is an essential component of a company's IT infrastructure and enables secure access, analysis, and use of data for business purposes. Data centers play a central role in providing and managing highly available and highly secure storage solutions to ensure the data integrity, compliance, and business continuity of their clients.

«Cloud & Hosting» refers to the supportive IT infrastructure and services of a data center, enabling customers to operate digital applications, websites, and data in a secure, scalable, and highly available environment. This includes both cloud services and hosting services. Cloud services offer customers the ability to use data and applications over the internet via virtual servers. Hosting services, on the other hand, refer to the provision of physical servers, where customers retain control over the infrastructure.

Data recovery refers to the process of restoring lost, damaged, or deleted data from electronic storage media and servers. An effective data recovery process includes assessing the damage, selecting the appropriate recovery methods, and ensuring that the recovered data is complete and intact. Data centers often offer data recovery services as part of their offerings.

Colocation Cage, also known as Private Cage, refers to a private rack section within a data center, which protects racks with its own housing made of security grids. With a Colocation Cage, you thus receive a separated rack area with a secured, private cage access.

Colocation Suite, also known as a Private Suite, refers to a dedicated high-security room within a data center that provides maximum protection for racks. The physically separated room – essentially a data center within a data center – usually has exclusive access and is secured with modern access solutions.
