Container as a service (CaaS) is a cloud service where the provider offers enterprises a platform to manage, deploy, and scale container workloads. CaaS streamlines the process of running container workloads by abstracting away the complexities of deployments and underlying server resources.
Here, we’ll take a closer look at CaaS, how it works, and what enterprises can do to secure their workloads when using CaaS.
Container as a Service (CaaS) platforms come in several varieties, and how each platform works can vary depending on the type of CaaS platform and the provider. For example, Google Cloud Run, AWS Fargate, and Azure Container Instances are CaaS platforms that allow enterprises to deploy containers using a serverless model.
Other forms of CaaS — sometimes described as Kubernetes as a Service — include managed Kubernetes (K8s) platforms like Amazon Elastic Kubernetes Service (EKS), Google Kubernetes Engine (GKE), and Azure Kubernetes Service (AKS). With these platforms, the service provider enables enterprises to run Kubernetes without installing or maintaining nodes or the K8s control plane.
While the specific implementations of CaaS will vary, a high-level breakdown of how container as a service (CaaS) works is:
From the perspective of the modern enterprise, CaaS brings many of the traditional XaaS benefits to the world of containers. Specifically, the benefits of CaaS include:
CaaS is often compared to two other XaaS models: Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). Conceptually, CaaS sits between IaaS and PaaS when it comes to levels of control and abstraction.
With IaaS platforms (like AWS EC2 and Azure VMs), the service provider abstracts away hardware, and enterprises can fully configure everything from the operating system to the application stacks they run. With PaaS (like AWS Elastic Beanstalk and Heroku), the service provider abstracts away the hardware, underlying operating system, and runtime environments to provide enterprises a platform for building applications.
With CaaS, enterprises have control over the containers they deploy and this allows a higher level of customization than PaaS. For example, while PaaS runtimes are all the same, each container on a CaaS platform could be built from a completely different tech stack.
Fundamentally, CaaS security is a subset of container security. While service providers take care of security “of the cloud”, enterprises are still responsible for security “in the cloud”. As a result, enterprises still need to follow container security and Kubernetes security best practices when using CaaS.
For example, key aspects of enterprise CaaS security include:
CheckPoint’s CloudGuard Container Security fully integrates into CI\CD pipelines and provides end-to-end security throughout the software development lifecycle. With CloudGuard, enterprises can protect their workloads against modern threats whether they build their own clusters or use CaaS.
With CloudGuard, enterprises gain a robust container security solution that can:
