Private hosting for your SAP systems may a bit more expensive, but the question often asked, is if the costs are worthwhile, when against the benefits are compared to those offered with public hosting, or even if an alternative that combines the two in a hybrid approach may be more appropriate. One of the benefits of private hosting, is that it puts more control in the hands of the businesses, and there is usually much structural integrity. Even though applications and data are in the same server, there can be more robust seperation, and resources are more dedicated to the user. At some point, if your business continues to grow, there may come a time when more control is needed, and Private hosting may be a logical option. As there are advantages to both public and private and public SAP hosting, they both also come with disadvantages, and considerations should include an examination of both advantages and disadvantages against current requirements.
With public SAP hosting, much of the performance depends primarily on the platform. In several instances, some applications must be tailored to the platform which the SAP installation is operated. Differences between Linux and Windows can be expected, and with public hosting, reconfiguration is often impossible, because other users are usually sharing the same space. The collorary, is that there should be no concern for hardware performance, because in most cases, it is beyond your control. There may also be some additional options with the use of VPS, as some providers may offer fully managed, or user-managed services. With the choice of a VPS for SAP applications, the option of reconfiguration may be made available, but some technical knowledge, may be required. The bigger benefit can be realized with better opportunities for optimizing processes, as the most suitable configurations can be made.With better configurations, savings in both time and resources can be realized, as the SAP system can run more efficiently.
Performance of your SAP system on public hosting can be impacted by a number of factors, that will include, the number of sites and users, loading capacity and server reliability. Although some of these factors may still be present with private packages, the user will have more control to structure applications on more stable areas with restricted access.
Another understated benefit of private hosting for SAP systems, it that it may be easier to scale as the business grows. Resources on public hosting are often limited to specific allocations, but increasing allocation is much easier on VPS, and can often be done with a click.
The costs of computing resources continue to decrease, however, if the costs of private hosting is still prohibitive, another alternative is a hybrid approach, that combines aspects of both public and private hosting in one package.
Hybrid hosting combines the physical use of a server with virtualization technology, and users are able to share resources and applications in the same manner as done in cloud computing, however hybrid hosting costs are usually less than the use of dedicated private servers, while concerns of loading capacity and reliability are minimized. The main advantages are the control it offers, it offers without the associated costs of private hosting. There are several variations offered within the area of hybrid hosting as some providers will allow you to reallocate resources in order to meet demand, and may also include features such as load balancing.
With hybrid hosting, the process offers scalability,flexibility and agility, as you often use only the resources that are needed. The hosting management enviromen may be even more powerful than public hosting as everything can often be handled from a single control panel. Hybrid hosting for SAP systems may be more cost effective as there are no costs for installation, and server costs are controlled mainly by demand as you may only pay for what is used.
Hybrid hosting may be the best of worlds solution for many businessses, as it includes important aspects of flexibility, security and scalability, with the connectivity of cloud computing and the perfomance of private hosting. Additionally it can be accomplished with minimal investment in infrastructure or hardware. It is also ideally suited for SAP systems that are database driven,and those that are expected to experience some growth.
