From entry to entry: what is CaaS?

——Introduction——

overview

Containers as a Service (CaaS) is a cloud service that helps manage and deploy applications using container-based abstractions. CaaS supports on-premises or cloud deployments. This article kicks off a " Container Application Journey (Red Hat) ".

Providers provide a framework or orchestration platform on which containers are deployed and managed, and it is through this orchestration that key IT functions can be automated.

CaaS is especially useful for developers who want to create more secure and scalable containerized applications. Users only need to buy the resources they want (scheduling capabilities, load balancing, etc.), saving money and increasing efficiency.

Containers create a consistent environment for rapid development and delivery of cloud-native applications that can run anywhere.

Why use containers

In the category of cloud computing services, CaaS is considered to be a subset of Infrastructure as a Service (IaaS), between IaaS and Platform as a Service (PaaS).

The basic resource of CaaS is the container, which is a common deployment mechanism for cloud-native applications and microservices. Additionally, CaaS can improve portability between environments, whether hybrid or multi-cloud. There are many benefits to using containers:

Portability: Applications developed with containers have everything they need to run and can be deployed in a variety of environments, including private and public clouds. Portability also means flexibility, as you can more easily move workloads between environments and providers.
Scalability: Containers are capable of horizontal scaling, which means users can multiply the number of identical containers in the same cluster to scale as needed. By using and running only what you need, when you need it, you can drastically reduce costs.
Efficiency: Containers require fewer resources than virtual machines (VMs) because they do not require a separate operating system. You can run multiple containers on a single server, and they require less bare-metal hardware, which means lower costs.
Greater security: Containers are isolated from each other, which means that if one container is compromised, the others are not affected.
Speed: Because containers are autonomous from the operating system, they start and stop in seconds. This also speeds up development and operations work, while resulting in a faster and smoother user experience.

Things to Consider When Choosing a CaaS Provider

Businesses looking to deploy container services for their business can choose to purchase a platform and manage the containers on the platform themselves, or they can choose a provider-managed container solution such as Google Cloud Platform, Amazon Web Services (AWS), IBM Cloud, or Microsoft Azure ). Thanks to the flexibility of containers, none of these scenarios means users will be locked out.

When making decisions about CaaS, keep the following in mind:

Are you new to containers, or have you established a container-based architecture? The managed container platform option is probably best for those new to containers, as it lets you try and choose what works for you.
Should you choose public cloud or on-premises?
Is your IT department trained and equipped to manage container platforms?
What is your budget? How large do you expect to grow?

Kubernetes container orchestration

Kubernetes is an open source platform for Linux container orchestration, originally developed by Google engineers. It automates application development, management, and scaling by combining containers running on Linux hosts into clusters and automating management. Many of the manual processes involved in deploying and scaling containerized applications are handled for you behind the scenes.

Kubernetes can give you the orchestration and container management capabilities to deploy containers at scale across multiple server hosts with multiple security layers, while managing the health of those containers over time.
