6 data center trends to watch for in 2021

Data centers face increasing complexity and operational challenges. According to the Uptime Institute, more and more companies are using the public cloud for their mission-critical workloads, but many are demanding transparency from cloud service providers in their infrastructure operations.

We look at key trends in capacity growth, spending, technology adoption, and workforce hiring among the results of Uptime Institute’s 2021 global data center survey.

Data center service disruptions are decreasing, costs are rising

Uptime examines the number and severity of service outages or outages over a three-year period in its annual survey. In terms of number of outages or outages, 69% of data centers surveyed in 2021 said that they experienced some service outage in the past three years. In 2020, the rate of this response was higher at 78%. According to Uptime, the improvement in the number of outages or outages appears to be related to changes in operations caused by the pandemic crisis.

“The recent improvements are partly related to the impact of COVID-19,” the report said. Contrary to expectations, there were no major data center outages in 2020. “This may be due to reduced enterprise data center activity, fewer on-premises and on-premises personnel, fewer upgrades, reduced workloads and traffic for many organizations, and increased use of cloud/public internet-based applications.” explained.

In terms of the severity of service interruptions, about 50% were found to have suffered loss or damage in terms of revenue, time, and reputation. According to this year’s report, about 20% of service disruptions were serious or significant.

Electricity was still the most common cause of service outages (43%), followed by network problems (14%), cooling problems (14%), and software/IT system failures (14%).

Growing mission-critical workloads in the cloud

Data center owners are moving more and more mission-critical workloads to the public cloud. However, some cloud users and prospective users are still concerned about visibility issues.

When asked if they have deployed their mission-critical workloads to the public cloud, 33% answered yes and 67% said no. In 2019, this ratio was 26% to 74%, with ‘yes’ increasing and ‘no’ decreasing. Those who answered ‘yes’ were divided into those who said they had adequate visibility into the operational resilience (resilience) of their services (18% of all respondents) and those who said they did not (15%).

Those who answered ‘no’ are also divided. 24% said they would move mission-critical workloads to the public cloud as visibility into the service’s operational elasticity increases. In contrast, 43% say they have not, or plan to, deploy their mission-critical workloads to the public cloud.

“As part of our efforts to attract large enterprise customers, we need to increase visibility, and cloud service providers are starting to respond,” Uptime said. “It’s still in its infancy as competition increases and compliance requirements expand, but it will be accelerated by the trend of increased accessibility and auditability.”

Despite concerns about visibility and operational transparency, 61% of respondents who have distributed their workloads on-premises, in the cloud, and across co-location facilities say that workload distribution enhances resiliency. Only 9% of organizations say their organizations have lost their resilience when using these architectures.

Public cloud repatriation does not occur

According to uptime research, workloads placed in the cloud tend to stay in the cloud. About 70% of respondents answered ‘no’ when asked if they had moved data from the public cloud back to a private on-premises/colocation environment. For 32% of respondents who answered ‘yes’, the top reason for relocating was cost, followed by regulatory compliance. Other performance issues and security concerns were also reasons. In fact, only 1% of workloads relocated because of a security breach.

“We know a lot of companies bring their workloads back from the cloud, but the workloads they deploy in the public cloud usually stay there,” Uptime explains.

Edge continues to expand

Most of those surveyed expect edge computing demand to grow in 2021. 35% of respondents expect edge computing demand to continue to grow. On the other hand, 26% expect a significant decline in demand.

The largest percentage, 40%, expected that private edge data centers will be mainly used depending on the future deployment situation. Next, 18% expect a mix of private and colocation. The rest said they plan to mainly use colocation (7%), outsourcing (3%) and public cloud (2%).
