In January 2017, RightScale surveyed 1,002 technical professionals across a broad cross-section of organizations about their adoption of cloud computing. The 2017 State of the Cloud Survey identified several key findings:
Azure increases market penetration, reducing the AWS lead.
Overall Azure adoption grew from 20 to 34 percent of respondents, while AWS stayed flat at 57 percent of respondents.
Google also grew from 10 to 15 percent to maintain third position.
Azure also reduced the AWS lead among enterprises; Azure increased adoption significantly from 26 percent to 43 percent while AWS adoption in this group increased slightly from 56 percent to 59 percent.
Hybrid cloud is the preferred enterprise strategy, but private cloud adoption fell.
Private cloud adoption fell from 77 percent to 72 percent, also bringing hybrid cloud adoption down from 71 percent to 67 percent year-over-year.
85 percent of enterprises have a multi-cloud strategy, up from 82 percent in 2016.
95 percent of organizations surveyed are running applications or experimenting with infrastructure-as-a-service.
Cloud users running applications in 8 clouds on average.
Cloud users are already running applications in an average of 1.8 public clouds and 2.3 private clouds.
They are experimenting with an additional 1.8 public clouds and 2.1 private clouds.
Companies run a majority of workloads in cloud.
Respondents run 41 percent of workloads in public cloud and 38 percent in private cloud.
Among enterprises, respondents run 32 percent of workloads in public cloud and 43 percent in private cloud.
Enterprise central IT teams take a stronger cloud role.
Enterprise central IT has a broader view of its cloud role in 2017 that includes selecting public clouds (65 percent), deciding/advising on which apps move to cloud (63 percent), and selecting private clouds (63 percent).
In comparison, respondents in business units are less likely to delegate authority to central IT for selecting public clouds (41 percent), deciding/advising on which apps move to cloud (45 percent), and selecting private clouds (38 percent).
Despite this disconnect, enterprises continue to progress on cloud governance; 70 percent of respondents have now defined the value they want to achieve from cloud, up from 63 percent in 2016, while 53 percent now have a timeline for implementing a cloud strategy, up from 48 percent in 2016.
Cloud challenges decline overall: Expertise, security, and spend tie for #1.
Lack of resources/expertise, the #1 cloud challenge in 2016, was less of a challenge in 2017 with only 25 percent citing it as a major concern, down from 32 percent in 2016.
Concerns about security also fell to 25 percent vs. 29 percent last year.
Managing cloud spend fell only slightly from 26 to 25 percent to tie for the biggest challenge.
The most cited challenge among mature cloud users is managing costs (24 percent) while among cloud beginners it is security (32 percent).
Significant wasted cloud spend drives users to focus on costs.
Cloud users underestimate the amount of wasted cloud spend. Respondents estimate 30 percent waste, while RightScale has measured actual waste between 30 and 45 percent.
Despite an increased focus on cloud cost management, only a minority of companies are taking critical actions to optimize cloud costs, such as shutting down unused workloads or selecting lower-cost clouds or regions.
Optimizing cloud costs is the top initiative across all cloud users (53 percent) and especially among mature cloud users (64 percent).
Docker shoots into the lead for DevOps tools.
Overall DevOps adoption rises from 74 to 78 percent with enterprises reaching 84 percent. 30 percent of enterprises are adopting DevOps company-wide, up from 21 percent in 2016.
Overall Docker adoption surges to 35 percent, taking the lead over Chef and Puppet at 28 percent each.
Kubernetes adoption also grew strongly to 14 percent from 7 percent in 2016.
An even higher percentage of enterprises use Docker (40 percent) with 30 percent more planning to use it.
Many respondents use Docker through container-as-a-service offerings from cloud providers including AWS ECS (35 percent), Azure Container Service (11 percent), and Google Container Engine (8 percent).
Use of Puppet and Chef fell this year from 32 percent to 28 percent of respondents for each. Ansible stayed steady, used by 21 percent of respondents vs. 20 percent in 2016.
Public cloud users still have a larger footprint in AWS.
AWS holds a significant lead in the number of VMs its users are running: 28 percent of respondents have more than 100 VMs in AWS, while only 13 percent have more than 100 VMs in Azure.
Among enterprises, 38 percent have 100+ VMs in AWS, and 21 percent have 100+ in Azure.
Private cloud adoption flattens.
VMware vSphere continues to lead with 42 percent adoption, slightly below last year (44 percent).
OpenStack (20 percent) and VMware vCloud Suite (19 percent) were also flat in growth, with OpenStack barely eking into #2 slot.
Among enterprises, VMware vCloud Suite (28 percent) beats OpenStack (25 percent)
Azure Pack/Stack was the only private cloud technology to show significant growth, up from 9 percent to 14 percent.
