Apakah Container as a Service (CaaS)?

Containers as a Service (CaaS) adalah layanan cloud yang mengelola kontainer dalam skala besar, termasuk memulai, menghentikan, menskalakan, dan mengatur beban kerja dalam kontainer. Contoh dari CaaS service adalah Amazon Elastic Container Service (ECS), Amazon Fargate, dan Azure Container Instances (ACI).

CaaS platform kontainer adalah jalan tengah antara container engine seperti Docker, yang memungkinkan Anda mengelola masing-masing container tanpa kemampuan orkestrasi, dan orkestrasi berfitur lengkap seperti Kubernetes, yang menyediakan kemampuan manajemen cluster yang kuat, tetapi kompleks untuk disiapkan dan dipelihara.

Dalam scope layanan cloud computing, CaaS menyediakan lebih banyak kemampuan daripada Infrastructure as a Service (IaaS), tetapi memiliki fitur yang lebih sedikit daripada kebanyakan penawaran Platform as a Service (PaaS). CaaS paling sering digunakan dalam model IaaS, kecuali unit sumber daya utamanya adalah container, bukan mesin virtual (VM) atau server bare metal.

Caas vs. PaaS

Platform as a Service (PaaS) involves third parties providing a combined platform, including both hardware and software. The PaaS model allows end users to develop, manage and run their own applications, while the platform provider manages the infrastructure. In addition to storage and other computing resources, providers typically offer a set of tools for application development, testing, and deployment.

CaaS differs from PaaS in that it is a lower-level service that only offers a specific infrastructure component—a container. CaaS services may provide development services and tooling like CI/CD release management, which brings them closer to a PaaS model.

Caas vs. IaaS

Infrastructure as a Service (IaaS) provides raw computing resources such as servers, storage, and networks in the public cloud. It allows organizations to scale up resources without upfront expenditure, and with low risk and overhead.

CaaS differs from IaaS in that it provides an abstraction layer above the raw hardware resources. IaaS services like Amazon EC2 provide compute instances, which are essentially computers with operating systems running in the public cloud. CaaS services run and manage containers on top of these virtual machines, or in the case of services like Azure Container Instances, allow users to run containers directly on bare metal resources.

Caas vs. FaaS

Function as a Service (FaaS), also known as serverless computing, is suitable for users who need to run a specific function or component of an application, without managing servers. With FaaS, the service provider automatically manages physical hardware, virtual machines, and other infrastructure, while the user only provides code and pays per duration or number of executions.

CaaS differs from FaaS in that it does provide direct access to infrastructure—users can configure and manage containers. However, some CaaS services, like Amazon Fargate, use a serverless deployment model to provide container services while abstracting servers from users, making them more similar to a FaaS model.


How CaaS Works

CaaS provides capabilities that automate the deployment and hosting of containers across multiple cloud environments. CaaS does not rely on one code stack or language, which is why you can implement CaaS in multicloud and hybrid cloud environments.

The automation provided by CaaS can significantly increase the efficiency of your pipeline. Since many tasks are automated, development and IT staff gain more time and productivity increases. Additionally, automation can speed up processes and ensure the ecosystem remains consistently up-to-date.

Top Container as a Service Providers

Amazon Elastic Container Service (AWS ECS)

Amazon Elastic Container Service (ECS) is a cloud service that manages and scales containers, without requiring developers to configure or set up the environment. ECS runs applications on groups of servers called clusters, allowing developers to control them through API calls.

ECS evaluates and monitors CPU and memory utilization to determine optimal container deployment on hardware resources. It closely integrates with AWS Elastic Load Balancing (AWS ELB), Elastic Block Store (AWS EBS) for persistent storage, and Identity and Access Management (AWS IAM) for access control.

Azure Container Instances

Azure Container Instance (ACI) is a service that allows developers to deploy containers directly on Microsoft Azure hardware without the need to provision or manage infrastructure. There is no need to configure and manage virtual machines and implement container orchestration platforms, such as Kubernetes.

You can easily launch new containers through the Azure portal or Azure CLI, and Microsoft automatically configures and scales your underlying compute resources. The service supports both Linux and Windows containers. ACI supports the use of images from public container registries like Docker Hub and Azure Container Registry, and can be integrated with private registries.

Google Cloud Run

Google Cloud Run is a fully managed serverless platform that allows you to run Docker container images as stateless, auto-scaling HTTP services. Unlike pure serverless platforms, Cloud Run can do more than run small functions in a limited interface. You can use containers to run complex applications with multiple endpoints.

Google Cloud Run automatically scales the number of container instances in response to incoming requests from each application. It also provides a concurrency setting that specifies the maximum number of requests a particular container instance can handle.
