Hardware suitable for cloud environments

Key to Success

Special Hardware for Remote Access

Finally, I would like to point out a factor that many administrators lose sight of when working in cloud environments and also forget about when planning: remote access. Remote access is usually implemented through the out-of-band interfaces of the servers, which usually also provide a separate network interface card for this purpose. In concrete terms, however, this means you need to build a complete network for access to the management interfaces, including your own switches. Alternatively, the switches for the servers can be used, but these are usually equipped with small form factor pluggable (SFP) ports. Classical management interfaces, on the other hand, rely on RJ45, so appropriate optics are required (Figure 5).

Conclusions

At the end of the day, finding the right hardware combination for your scalable environment is not rocket science. However, it does require thorough planning in advance, and costing the final sales price is a fundamental key to success. If you want to make it big as a provider with a scalable environment, you should not shy away from the effort.
