Survey Methodology & Respondents

Survey Methodology & Respondents (1/5)

  • during September and October 2019
  • received 1,337 responses

SMR (2/5)

  • There was a nearly even proportion of respondents from Europe (37%) and North America (38%), followed by Asia (17%).

SMR (3/5)

  • The majority of respondents (71%) were from organizations with at least 100 employees, the largest portion of these coming from enterprises with more than 5,000 employees (30%).

SMR (4/5)

  • Two-thirds of the respondents were in the software and technology industry, with the remainder coming from other professional service industries.

SMR (5/5)

  • The top job functions were software architect (41%), DevOps manager (39%), and back-end developer (24%).

Application Development & Delivery

Release cycles continue to accelerate

App D&D (2/6)

  • Those with daily release cycles increased from 15% in 2018 to 27%, and weekly release cycles have increased 20% to 28%.

App D&D (3/6)

  • Hybrid approaches, using a combination of manual and automated tools, are up to 41% in 2019 compared to 25% last year.
  • Doing releases manually has dropped to 14% from 27%.

Application Development & Delivery (4/6)

  • This can be attributed to a rise in available CI/CD tools, the most popular being Jenkins (58%), followed by GitLab CI/CD (34%), and CircleCI (13%).
  • These tools are also becoming more reliable. Less than 11% of respondents indicated they built custom scripts this year, down from 26% in 2018.

App D&D (5/6)

  • Comparing the data from 2019 and 2018, respondents are checking in code less frequently.

App D&D (6/6)

  • At the same time, the number of machines in an organization’s fleet continues to increase.

Most notably, the use of containers in production increased significantly.

Containers (2/5)

  • This year, 84% of respondents are using containers in production, an impressive jump from 73% in 2018, and from 23% in our first survey in 2016.
  • Hint: Ref to SMR (4/5) Industry.

Containers (3/5)

  • As organizations are trusting their production workloads to containers, they are also using more of them.

Containers (4/5)

  • According to CNCF’s Cloud Native Landscape, there are more than 109 tools to manage containers, but 89% are using different forms of Kubernetes.
  • Hint: Ref to SMR (4/5) Industry.

Containers (5/5)

  • Cultural challenges with the development team remain the top challenge in using/deploying containers (43%).
  • Hint: Cultural changes.

Cloud Native Tools

While use in production is still rather low with 18% of those who responded indicating they use a service mesh project, 47% are evaluating the use of a service mesh.

CN Tools (2/6)

Service Mesh

  • Istio (69%) and Linkerd (64%) were the top two tools being evaluated, suggesting they will see significant increases in use in production in coming years.

CN Tools (3/6)


  • Top-3 are public cloud storage projects.
  • More than half of respondents were evaluating Rook – more than any other project.

CN Tools (4/6)


  • Of those who are using serverless, 80% use a hosted platform and 20% use installable software.

CN Tools (5/6)

Hosted Serverless Platforms

  • Of the hosted platforms in use, the top tool is AWS Lambda (53%). Google Cloud Functions (18%) and Azure Functions (14%) are a distant second and third.

CN Tools (6/6)

Installable Serverless Platforms

  • Of the installable software in use, Knative is the tool of choice (34%), followed by OpenFaaS (15%) and Kubeless (11%).

CNCF Technologies

99% of respondents indicated they are using or evaluating at least one graduated or incubating CNCF technology in production.


  • Prometheus and CoreDNS also saw considerable jumps in use in production.


  • For incubating projects, Helm saw the largest increase since last year, growing 41% to reach 69% usage in production. etcd was the most widely used, with 83% use in production.



Kubernetes (1/8)

Production Clusters

  • Of those using Kubernetes, most respondents have 2-5 clusters in production (43%).


Packaging Applications

  • Helm remains the most popular tool for packaging Kubernetes applications.


  • the majority (70%) of respondents plan to autoscale their stateless applications,
  • followed by 40% for task/queue processing applications,
  • and 34% of stateful applications.


  • Of those who are not using Kubernetes autoscaling capabilities, 35% do not want to autoscale any works at this time, and 12% are using a third-party solution.


Ingress Providers

  • nginx kept its lead this year as the top Kubernetes ingress provider (62%),
  • followed again by HAProxy (22%).
  • Envoy overtook F5 for the third spot (up from 4 in 2018) with 19%.


Separating K8s Applications

  • Namespaces are the most popular way to separate Kubernetes applications for all respondents, including those with multiple teams.


Monitoring, Logging, and Tracing

  • 23% report that they do not use tracing, compared with just over 3% for both monitoring and logging.
  • Hint: Tracing.


Local Container Development

  • Minikube (39%) and Docker Kubernetes (32%) are the most popular Kubernetes environments during local container development.


Key Takeaways (1/2)

  • Survey Methodology: Scope v.s Industry
  • (Release cycles)+++ v.s (Check in code)-
