Hybrid cloud is seeing a rapid growth rate for adoption that is surpassing multiple private and multiple public clouds adoption.
In their 2015 State of Cloud survey, RightScale revealed that 82% of enterprises preferred hybrid cloud, an increase from the 70% hybrid adopters in 2014.
Meanwhile, private cloud saw minimal gains in adoption rates, with VMware vSphere and vCloud Director usage up by 1% and 2% respectively.
Public cloud is still leading the way in overall usage across enterprise and midmarket organizations alike, but its future growth rate is nothing compared to hybrid.
Cloud investors are considering hybrid cloud because it offers the flexibility to keep certain data on-premises. Organizations can take advantage of the compute capacity, the lower TCO, and the scalability that the cloud offers for managing some of their workloads without an all or nothing hosting approach.
Toby Owen, vice president of product for Pier 1 Hosting, explained, “The proposition of hybrid cloud is very compelling: Cost savings, business agility, and operational efficiencies are the qualities IT decision-makers are looking to bring into their organizations.”
Despite hybrid cloud being identified as the cloud model of choice moving forward, we are still in the experimental stage when it comes to widespread hybrid cloud deployments.
We are seeing companies dip their feet into the water, but they aren’t plunging in face first.
In an interview with Computer World, Allan Krans, an analyst with Technology Business Research, stated, “Hybrid is at the early stages of the maturity cycle. Hybrid is growing, but it will take a lot of experience to really grow it for more critical applications.”
Two significant factors that are impacting how quickly organizations are deploying hybrid cloud are data prioritization and network utilization.
On the data prioritization front, businesses are faced with having to identify which application workloads are to be kept on-premises, behind their firewalls, and hosted in the cloud.
How they prioritize their workloads will impact their data security, their resource allocation, their storage capacity, and their infrastructure performance.
Security and capacity needs to play a big part in determining which data should by hosted.
For instance, organizations may need to offload their data storage needs if they encounter seasonal surges in application utilization. Or they may need to take extra measures to protect and manage their data on-premises due to confidentiality or sensitivity. Data location and data access can be better controlled this way.
The tripping point comes when those critical, more frequently accessed applications also need an added layer of security. At that rate, hybrid still presents the opportunity to host that information in the cloud to cut down on latency and amplify performance results.
However, if the data and applications aren’t logically sorted and prioritized, network performance can be inconsistent.
Reliable network performance is critical to adequately handling in-house application workload demands and, in some cases, cloud performance. It just depends on what type of cloud model or models are being deployed, as well as whether third-party services are being utilized.
Either way, the network scheme will need to be reexamined.
According to a study conducted by Enterprise Networking Planet, “73% of respondents indicated that they had to change their network infrastructure to support their rollout of private or hybrid clouds.”
This group rated the most critical network factors that will be significantly impacted (defined as hardware upgrade and network refresh demands) by a hybrid cloud deployment:
- Network security (50% of the responses)
- Network bandwidth (42% of the responses)
- Network performance (42% of the responses)
- Network reliability (39% of the responses)
