13 Data Center Trends that Died in 2015

13 Data Center Trends that Died in 2015

There are constant predictions that data centers are dying. One survey reported that many companies plan to close small data centers and consolidate facilities. But that doesn't mean data center spending will decrease; spending will be stable or even increase in 87% of businesses, with a focus on upgrades and migration to colocation and the cloud.

But even though the death of the data center as a whole is overstated, there are many data center trends that won't continue. Here's a look at a baker’s dozen of data center trends that are dead or heading that way.

1. Disks Are Dead

The traditional spinning hard disk drive has faced tremendous competition from solid-state drives, also known as flash. Flash offers better performance than disk, but has been more expensive. That's changing, however; Wikibon expects flash to be more cost-effective than disk starting in 2016.

2. Manual Backups Are Dead

Building comprehensive and reliable backup methods has been difficult for businesses. One survey found that 71% of companies were not confident they could fully restore their data. With the move to virtual machines and cloud environments, however, backups simply come along with the architecture.

3. Tape Backup Is Dead

In virtual and cloud environments, archiving on tape is no longer necessary. Newer software-defined storage technology provides cost-effective backup without the slow workflows required of tape.

4. Business Continuity and Disaster Recovery Are Dead

A new discipline, IT service continuity, will combine the responsibilities of the separate business continuity and disaster recovery teams. The approach relies on being able to forecast service outages and dynamically reallocate work to other service locations.

5. Perimeter-Based Security Is Dead

The growth of cloud services and “bring your own device” (BYOD) has blurred the boundary separating corporate networks and devices from the rest of the world. As a result of this, simple firewall-based security is no longer adequate. While firewalls will never go away, applications can no longer rely on the network's defenses to keep bad guys out; apps need to take ownership of the responsibility for protecting themselves.

6. DMZ-Based Security Is Dead

The growth of virtual machines means that the distinct components of a traditional three-tier application run on the same physical server. As a result, the traffic simply flows through a virtual switch with no opportunity for firewalls and network segments to offer protection.

7. Signature-Based Antivirus Is Dead

Signatures can only protect against known threats; for companies that have effective patching programs, the biggest threat comes from zero-day attacks, before patches have been distributed and installed. In order to protect against these, companies will rely more on software that detects malware based on anomaly detection.

8. Shadow IT Is Dead

Departments aren't going to stop looking for their own IT solutions when the company IT department is too slow, but businesses are going to stop fighting the usage. Now that cloud is more common, with services provided by trusted providers like Microsoft and Oracle, businesses will find ways to oversee departmental usage of these services without attempting to prohibit it.

9. IPv4 Is Dead

The US ran out of IPv4 addresses this summer. As a result, all networks need to implement IPv6 and will need to support both protocols until the full transition is completed.

10. BYOD Is Dead

Companies aren't going to completely eliminate BYOD, but they'll reclaim control by switching to CYOD (choose your own device) policies that limit end users to specific types of devices and require corporate control over them.

11. Hypervisors Are Dead

Virtualization isn't going away, but container-based virtualization, which is more lightweight virtualization than hypervisors, is growing in popularity. Google uses containers for all of its software.

12. Traditional Servers and Storage Are Dead

Building systems out of separate components is being replaced by the use of converged and hyperconverged solutions. Close to half of all businesses already use converged infrastructure, and 44% of the rest are thinking about it.

13. Manual Data-Center Management Is Dead

Both the growth of the software-defined data center and increased usage of data-center infrastructure management software will make managing data center facilities more automated.
