The State of Containers: Unraveling a Few Mysteries  

Agility and quick releases have been the cornerstone of the evolution of the IT industry. As the demand for various features increased, the size and complexity of applications also grew. In these circumstances, deploying quickly and ensuring faster releases was a huge obstacle. It gave birth to the concept of containers. The last few years have seen a massive acceleration in container adoption, making it a mainstream technology.

Looking at the bright future of containerization, we have dived deep into the application container market and curated a report by collecting information from reputed sources like Mordor Intelligence, RedHat, CNCF, Datadog, Gartner, and many more, to unravel a few of the mysteries of the state of containers.

Key takeaways:

  • At 46% Containerization, is the topmost software development priority for developers across the globe.
  • By 2023, 70% of organizations will effectively run two or more containerized applications.
  • North America is the largest, while the Asia Pacific is the fastest-growing application container market worldwide.

10. Kubernetes has become a mainstream container technology

96% of the organizations are either using or evaluating Kubernetes as the preferred container technology.

If you break this number region-wise, the statistics will look as follows:

a. Regions with the highest usage of Kubernetes in production

regions-highest-kubernetes-in-production

Africa (73%) tops the charts, followed by Europe (69%) and South & Central America (62%).

b. Regions with the highest usage of Kubernetes in test production

regions-highest-kubernetes-test-production

Australia and Oceania (42%) are at the forefront, followed by North America (30%) and South & Central America (29%).

c. Regions with the lowest Kubernetes adoption

regions-lowest-adoption-of-kubernetes

Asia (19%) shows the lowest adoption, followed by North America (14.4%) and Australia & Oceania (13%).

11. The rise of Kubernetes pods and auto-scaling

pod-count-over-a-time-period

The organizations using Kubernetes in production to scale their environments are using double pods on average compared to the past two years, showing that Kubernetes adoption has increased significantly.

auto-scaling

Also, with the rise of Kubernetes adoption, auto-scaling has become more popular among organizations than ever, as Kubernetes can automatically scale pods horizontally or vertically based on the metrics reported from Kubernetes.

12. Managed Kubernetes service adoption

managed-kubernetes-adoption

90% of the Kubernetes users leverage cloud-managed services like Amazon Elastic Kubernetes Service (EKS), Google Kubernetes Engine (GKE), and Azure Kubernetes Service (AKS) instead of running self-managed containers to build highly available, scalable, and performant apps.

13. Host density of Kubernetes is 3X higher compared to ECS

kubernetes-vs-ecs-host-density

If you compare Kubernetes and ECS on the scale of host density, Kubernetes can run 16 pods/host, while ECS can run 5 tasks/host on average. So, the host density on Kubernetes is 3X higher than ECS, showing its ability to optimize resource utilization.

14. AWS ECS user’s workload management pattern

aws-ecs-workload-management

Organizations using Amazon ECS (Elastic Container Service) gradually shifted their workload from AWS Fargate to EC2 after 2017. While in 2017, 100% of ECS users were on EC2, in 2021, it dropped to 60%, with the remaining 40% captured by AWS Fargate, which shows the preference for container workload management is changing.

Conclusion

There are many trends related to containers right through the curated report suggesting one obvious thing is that containers are the IT industry’s future. The primary reason for containers’ is the business benefits they bring to the table, such as faster deployment and less time-to-market. Containerization will be the topmost priority of organizations seeking a digital transformation. So, it’s time to take action and adopt containerization as a core part of your business strategy.
