What Is Containers as a Service?

Containers as a Service (CaaS) is a cloud computing service that helps developers and IT teams easily deploy, manage, and scale containerized applications.

CaaS in 2025: A New Cloud Trend?

In 2025, the containers as a service market is expected to grow rapidly. Recent reports show that global revenues will increase from $3.6 billion in 2024 to $12.0 billion by 2030, with a compound annual growth rate of 22.4%.

This growth is driven by how lightweight containers help businesses use resources better, lower infrastructure costs, and scale applications quickly.

As a result, it is clear that CaaS will play a central role in helping businesses create agile, scalable, and cost-effective solutions, making it a major trend in 2025 cloud technology.

CaaS Adoption

The CNCF Annual Survey 2023 showed that by the end of the year, 90% of organizations using cloud-native technologies relied on containers for development and deployment.

This included businesses still testing containers, proving their growing importance in modern IT systems.

But even though containers are being used more, companies still face some challenges when adopting CaaS.

Growing Use of Serverless Containers

According to Datadog’s 2023 Container Report, 46% of organizations using containers used serverless containers, which was a big increase from 31% in 2021.

Serverless containers are a technology that allows cloud providers (like Google or AWS) to take care of the infrastructure for you. This means businesses don’t need to set up or manage servers manually. It reduces the time and effort needed for managing operations and allows developers to focus more on creating apps.

Rise of GPU-Based Compute for AI and ML

The use of GPU-based compute in containerized workloads (applications running in containers) increased by 58% in 2023 compared with 2022.

This was much higher than the 25% growth in non-containerized GPU workloads recorded over the same period.

GPUs, originally designed for graphics in video games, have become essential for powering AI and ML applications, which need to handle large amounts of data. Containers prove to be a great way to run these GPU-intensive applications because they are flexible and easy to scale.

Prebuilt container images and managed Kubernetes services (tools for managing containers) made it easier for teams to integrate GPUs into their systems, improving their workflows and saving on costs.

Doubling of ARM-Based Compute Adoption

The adoption of ARM-based compute instances for containerized workloads more than doubled in 2023 compared with 2022, increasing from 2.6% to 7.1%.

ARM-based processors are more energy efficient than traditional x86 processors (the most common type of CPU) – meaning that they are popular because they help businesses save up to 20% on costs. Essentially, these types of processors consume less energy and produce less heat while still delivering on the performance aspect. This makes them ideal for running containerized applications in a cost-effective way.

Challenges in CaaS Adoption

Despite its growth, CaaS adoption still faced some barriers:

Beyond Kubernetes: Exploring the Container Ecosystem

Kubernetes is one of the most popular container compute services around the world, controlling around 26% of the containers as a service market.

This platform was developed by Google, and its open-source nature and ability to work across different environments – such as on-premises systems and hybrid clouds – have made it a favorite for businesses seeking flexibility and efficiency.

However, as of 2025, it is no longer the leading container services platform. The leading container services platform is actually Docker, which controls more than a third (around 34%) of the containers as a service market.

Originally a container runtime, Docker now includes orchestration features through Docker Swarm, making it a popular choice for organizations that value simplicity.

The containerization market also features many other platforms, each serving different purposes:

Hybrid Cloud Integration: The Role of Containers as a Service

Container compute services play an important role in helping businesses manage containerized applications across multiple cloud platforms. As more companies adopt hybrid clouds, CaaS offers the flexibility needed to ensure smooth operations across different environments.

In fact, data shows that 56% of large organizations preferred hybrid cloud computing services in 2023 because they combine the strengths of both on-premises and cloud environments.

Multi-cloud strategies, where companies used an average of 2.3 cloud providers, were also becoming more popular.

As hybrid cloud computing services become more common, cloud containers as a service are playing a key role in helping organizations reduce costs, improve performance, and achieve their digital transformation goals.

Security Concerns: Managing Risks in Containerized Environments

Security remained one of the biggest challenges for businesses using container platforms in 2024.

According to a 2024 report published by Red Hat, 67% of organizations delayed or slowed down application deployments because of security concerns in their containerized environments. This highlights how critical strong security measures are for maintaining efficient operations.

Containers as a Service (CaaS) providers offer important security features to handle the challenges of containerized environments. These features help organizations protect their applications throughout the development lifecycle, from deployment to runtime:

• Role-based access control (RBAC): CaaS providers use RBAC to ensure that only authorized people can access specific resources. This prevents unauthorized changes to container settings or access to sensitive data.
• Container isolation: By keeping containers separate from each other, CaaS platforms reduce the risk of vulnerabilities spreading between applications. This is especially useful in shared environments where many containers run on the same system.
• Built-in security scanning: Many CaaS platforms include tools to scan container images for vulnerabilities before deployment. These scans help detect outdated software or security misconfigurations.
• Automated security policies: Organizations can both create and enforce security policies automatically. For example, blocking unauthorized API access or ensuring that the containers meet compliance regulations.
• Runtime monitoring: CaaS platforms often have tools that continuously monitor container activity during its runtime. These tools can detect any suspicious activity, like unusual file changes or unexpected network traffic, and alert the business immediately.

Despite these measures, 89% of companies reported at least one security issue related to containers during the application lifecycle in 2024. The most common problems were:

These security issues had serious impacts on businesses. That year:

• 53% reported delays or disruptions in projects
• 46% suffered revenue or customer losses
• 30% faced fines or legal actions
• 26% reported employee terminations

To address these challenges, businesses need to improve their security strategies, invest in better tools, and encourage teamwork between DevOps and security teams.

Ensuring the safety of containerized environments is essential for maintaining smooth operations and safeguarding business results in the expanding containers as a service market.

The Bottom Line

Embracing CaaS could potentially boost your business’s efficiency.

Containers as a Service (CaaS) is changing how businesses create, manage, and secure applications in a cloud hosting-driven world. With features like role-based access control and container isolation, CaaS offers flexibility, scalability, and strong security, helping companies innovate faster while cutting costs.
