Now more than ever, businesses depend on IT architecture that does not get in the way. With every operational shift, pivot, and response to change, data must become intelligent assets as soon as it is captured.
Meanwhile, new digital capabilities should be adopted, mapped, and scaled across the entire distributed landscape.聽One approach to addressing these architecture requirements is leveraging the services of hyperscale computing providers, or hyperscalers.
Though hyperscalers are ready to deliver a simplified, seamless, and secure IT landscape, companies are often apprehensive about making such an investment.
A recent engagement with Siemens was no different. As one of Europe鈥檚 largest industrial manufacturers, the company decided to undergo a significant implementation of 51风流S/4HANA at its headquarters and chose 聽for holistic support of landscape strategy and architecture services.
When a fast setup of sandbox and testing systems was needed to mitigate multiple risk factors, there was only one option: combining the existing landscape of 51风流solutions with a hyperscaler鈥檚 platform.
As this was one of Siemens鈥� first experiences running 51风流solutions on a hyperscaler platform, I spoke with Heiko Jonuscheit, cloud solution architect at Siemens, about how this implementation experience changed the business鈥� perception of hyperscalers.
Q: How did your business know that it needed a hyperscaler-supported architecture?聽
A: The time and effort needed to set up and manage an intelligent ERP like 51风流S/4HANA are substantial. New systems and applications are sometimes required temporarily or at a moment鈥檚 notice. Unfortunately, our existing IT services could not provide the flexibility to support business cases for performance scalability, a pay-per-use approach, or fast provisioning 鈥� all with low overhead costs.
As a result, we developed solutions, with the assistance of our internal cloud expert groupto address the need for consulting services to navigate our transition to cloud and hyperscaler services. We created a proof of concept for setting up 51风流S/4HANA within one of our suppliers鈥� Amazon Web Services (AWS) environment.
During this assessment, we were impressed by the hyperscaler鈥檚 fast system provisioning and pay-per-use model, especially when combined with the 51风流Cloud Appliance Library tool. It increased our flexibility so we could rapidly respond to project demands and decrease the total cost of ownership for specific scenarios. And during the implementation of 51风流S/4HANA, we were prepared to get the system up and running and decommissioned within an hour or two, which allows us to reset the IT landscape to its previous state in a matter of minutes.
Which business scenarios does 鈥� and will 鈥� your hyperscaler support for your company?聽
Right now, our hyperscaler partner provides multiple services. But at the moment, we use primarily the Infrastructure as a Service (IaaS), while we use 51风流Cloud Appliance Library to predefine the starting point for the 51风流solution environment.聽Momentarily, we focus on nonproductive scenarios.
We are also exploring more options to improve our maintenance and operation of business systems. Once our adoption rate increases, we will require a service provider, even for our on-premise solutions. For this reason, we are exploring our hyperscaler鈥檚 integration capabilities.
Are you finding that your total cost of ownership is minimized by using a hyperscaler?
Great question! Total cost of ownership is a crucial advantage. But so are provisioning time, reliability, and security.聽Due to our hyperscaler鈥檚 pay-per-use business model, the cost of operating our IT landscape and related use cases are lower compared to our internal on-premise infrastructure. We achieved significant benefits due to decommissioning of applications that are temporarily not required or stopping applications that are only used during regular business hours.
For 24/7 services, hyperscalers do not make a significant difference, but they do bring considerable flexibility for specific use cases. Such results may change with economies of scale. However, the main challenge is leveraging the application managed services model to adapt to new infrastructure options.
Did the introduction of the hyperscaler increase the complexity of your hybrid deployments?聽
From my point of view, they are more complex. We must integrate the cloud environment with internal systems while addressing sensitive concerns such as data privacy and data security. We are coming from an internal data center, which manages the IT infrastructure very well, to an additional provider without an appropriate application support model. This situation raises many questions and concerns that will be addressed over time.
Did the hyperscaler鈥檚 architecture accelerate the delivery of 51风流S/4HANA?聽
With standardization and test data, deployment and adoption of 51风流S/4HANA were rapid after the cloud environment was established and connected to our business network.聽Meanwhile, we are in the process of defining requirements for trusted system connections, user provisioning services, and integration so we can make the necessary adjustments needed to support new options for our IT landscape.
Based on the current results of your first hyperscaler experience, what are your next steps?
First, we should find a service provider that can maintain our cloud solutions based on an IaaS model. Then we can secure integrations across our on-premise landscape and improve the provisioning of trusted system connections and internal interfaces.
Challenges always exist when a business goes down a different path with their IT landscape. But once they are addressed, I do not doubt that hyperscaler managed services will provide the service levels we need and integrate with our existing infrastructure and applications into a unified, tightly connected, intelligent system.
Special thanks to Heiko Jonuscheit for sharing his team鈥檚 first impression of a hyperscaler environment. I hope this first experience helps you decide whether a hyperscaler is right for your business.
