How Cloud Data Centers Compare to Traditional Data Centers
Before making any decisions about moving your data center to a cloud, you need to take the time to consider how cloud data centers compare to traditional data centers. Because of the high costs of infrastructure and administration, data centers are often one of the first business areas that companies consider switching to a cloud service.
If you’re tasked with planning your cloud strategy, how do you do what’s best for your organization? The first step is to simply find a cloud services provider, analyze how much it charges for the services you need, and compare it to the costs of your own data center. However, it is important to remember that it's unlikely that you'll find a single cloud service that does everything you're doing in your data center.
Ultimately, cloud services are attractive because the cost is likely to be far lower than providing the same service from your traditional data center.
| Traditional Corporate Data Center |
Cloud Data Center |
| Thousands of different applications |
Few applications (maybe even just one) |
| Mixed hardware environment |
Homogeneous hardware environment |
| Multiple management tools |
Standardized management tools |
| Frequent application patching and updating |
Minimal application patching and updating |
| Complex workloads |
Simple workloads |
| Multiple software architectures |
Single standard software architecture |
Looking at the table, it becomes clear that the cloud data center is much simpler to organize and operate and, because it is simple, it scales well. In other words, the larger you make it, the lower the costs per user are.
