Virtual Private Cloud (VPC)
The best of two worlds: A virtual private cloud (VPC) offers you the flexibility and cost-efficiency of the public cloud together with the security of a private cloud. In the Open Telekom Cloud, the setup of a VPN is a key prerequisite as a fundamental security measure for the use of almost all cloud resources. Every user receives at least one VPC.
A VPC lets a company build its own private environment on a shared public cloud infrastructure. This approach gives it an area that is logically isolated from that of all other public cloud tenants – a private, secure place for data.
For security and privacy reasons, many companies do not want to store their data in public cloud environments where they must share resources with other users. Accordingly, they set up a private cloud on their own servers or in a leased data center, with only company employees having access. However, operating such a private cloud is sometimes expensive as well as a burden on IT management.
A virtual private cloud is an alternative to the private cloud. It provides an environment within a public cloud that is strictly separated from other users’ areas. As an example, imagine the infrastructure of a cloud provider as a restaurant with tables. In a public cloud, users share resources – in other words, they take a seat at the tables that are currently free. A virtual private cloud is like a reserved table where only certain guests are allowed to sit.
A Virtual Private Cloud operated by Open Telekom Cloud offers several advantages over a self-operated and managed private cloud.
The Virtual Private Cloud of the Open Telekom Cloud consistently separates the virtual resources of different users in several ways.
A stable and fast connection to users' networks is crucial for effective use of the VPC of the Open Telekom Cloud. By default, every user can access the Open Telekom Cloud via the public Internet – encrypted via a virtual private network (VPN), of course. However, users share the connection over the Internet with others, which can have a negative impact on stability and speed. Companies therefore often prefer a dedicated connection via Direct Connect or PLAS (Private Link Access Service).
Direct Connect is an individual communication channel to the Open Telekom Cloud, ordered in bandwidths between 1 MBit and 10 Gigabits per second (Gbit/s). However, it requires quite a high degree of configuration effort because Deutsche Telekom has had to install and configure additional hardware in the data center for this purpose.
PLAS, on the other hand, enables a connection with little effort via Ethernet Connect or IntraSelect using multi-protocol label switching (MPLS). This approach enables companies to connect their corporate network to the Open Telekom Cloud with even higher availability and stability at up to 100 Gbit/s.
Companies also often need to connect resources within the Open Telekom Cloud – for example, a data storage unit with an HPC cluster for big-data calculations. Connecting these solutions over the Internet would entail additional costs and performance sacrifices. For such cases, the Open Telekom Cloud therefore offers VPC endpoints (VPCEP) that efficiently connect services without the need for an Elastic IP, NAT gateway, VPN, or PLAS connection.
