Despite massive growth of the cloud, companies are still turning to on-premises data centers for specific workloads, functions, and more.
If you were to read any number of headlines on cloud adoption, you may be tempted to think that the enterprise world is all-in on the cloud. However, you’d be wrong.
Sure, some 73 percent of organizations have at least one application or a part of their infrastructure in the cloud, according to an IDG report. But that’s only a part of their application portfolio or infrastructure: many companies still maintain some sort of on-premises infrastructure.
In the age of the cloud, what’s the point of an on-premises data center? Despite the hype, the cloud is very much still a nascent technology. While cloud security and performance, in many cases, can match that of on-premises technology, there are some instances when it’s better for companies not to migrate their apps and infrastructure to the cloud.
When considering a move to the cloud, companies must examine the limitations around compliance, security, latency, recovery time, availability, data location, and other factors, Cappuccio said. After considering those aspects, on-premises infrastructure still makes sense for many companies.
Here are the top 10 things companies are keeping in their own data centers.
- Predictable workloads
One of the biggest selling points of the cloud is its elasticity and flexible nature. However, that flexibility often comes at a high price, and may not be the best fit for predictable workloads.
“Anything super predictable and consistent will oftentimes be cheaper on-premise than in the cloud,” said Brent Collins, global director of the data center practice for World Wide Technology (WWT). “If you can buy equipment and have it highly utilized in a predictable fashion over a number of years, it’s probably cheaper to do it on-premises.”
