Hybrid cloud infrastructures can offer companies the best of both worlds: Low latency, high security and full control thanks to dedicated capacities (private) on the one hand, scalable resources for peak loads, on-demand billing and access to the latest services at all times on the other (public). However, a huge pitfall can already lurk in the construction of hybrid infrastructures. This is because companies are setting a decisive course for the subsequent management effort. Those who design public and private clouds with different hardware and software components, for example, need qualified employees for both instances who are familiar with both the peculiarities of the public cloud instance and the specifications of the on-premises resources.
A hybrid cloud with a uniform hardware and software basis is more efficient. This is because there is only one technology that has to be served; both for on-premises and in the public cloud. One example of such a construct is the Open Telekom Cloud Hybrid: Telekom supplies companies with hardware and software from the private instance to the required extent, takes care of setup and installation, and also handles operation and maintenance throughout the entire lifecycle.
Decisive: Usability across cloud boundaries
This results in a considerable comfort factor in the user experience (UX), which plays a central role when it comes to efficiency in dealing with the IT environment. For the operating teams of a hybrid cloud infrastructure, who work across the board by switching back and forth between public and private as a matter of course, a uniform UX can save considerable time. "Ideally, a hybrid cloud infrastructure should be operated via a single console with the same Graphical User Interface (GUI), in which on-premises and public clouds seamlessly merge," says Sascha Smets, Senior Product Manager at T-Systems. "One console and one world that combines all the advantages of public and private clouds.”
Ensure operational reliability around the clock
But IT management isn’t just about orchestrating resources via a console. Among other things, companies must also ensure that their systems meet the highest possible security standards. "This is another reason why it can be worth completely outsourcing operations and maintenance to a trustworthy service provider," says Smets. "Many companies operate their own servers around the clock, which run even when the IT department has long since finished work. A malfunction at night, which can lead to damage or loss of data, isn’t noticed until the next morning." Managed services from a provider such as Telekom, which monitors the operating status and provides 24/7 standard support, enable companies to ensure maximum reliability even for on-premises resources within a hybrid cloud infrastructure.
For example, in the event of a hardware failure: If a company operates an on-premises instance managed by Telekom, a hardware defect is immediately detected by Telekom, regardless of the time of day. In such a case, an exchange is initiated immediately. Malfunctions in the network or other management components are also registered and, if necessary, rectified as quickly as possible via remote access. Even the company's own applications can be managed by the provider around the clock, if necessary, in order to rectify downtimes as quickly as possible.
Manage PaaS and SaaS, too
And what about standard software? After all, more and more companies are not only using naked infrastructure from the cloud, but are also leasing applications – whether office packages, development platforms or entire SAP instances. "In this area, too, companies can cooperate with providers such as Deutsche Telekom. The advantages are the same: less effort, higher security and more time for the core business," says Sascha Smets.
Deutsche Telekom, for example, offers numerous standard services, such as SAP systems, which it also operates for companies on demand. The Open Telekom Cloud was certified by SAP for operation in the IaaS data centers in Magdeburg and Biere in Saxony-Anhalt. In addition, an SAP operating model is also available for the on-premises instance of the Open Telekom Cloud for companies, which can also be managed by Telekom if required. "A construct that we can offer for every standard service from our partner cosmos," says Smets. "In this way, with our hybrid cloud we are able to almost completely free companies from IT management tasks.”
