What is Containers as a Service?

Containers as a Service is a cloud service that helps developers and IT teams to organize, upload, scale, run, and manage containers with the use of robust container-based virtualization. The CaaS service providers offer its users high capabilities to best manage the deployed containerized app or the clusters.

Previously, developers were responsible for building applications. They had separate teams to manage the security and operations which in turn made them follow the monthly releases. To deploy an app with Kubernetes services, developers had to design the CI/CD pipeline and integrate it with the docker registry, security scans, creating configs with SSL, and building helm charts including working with Kubernetes, OpenShift, or AWS.

Containers as a Service sets out to automate these development services. It highlights the core importance of Cloud Computing landscape. CaaS offers the infrastructure, capabilities, tools, and resources that the developers require for app image deployment.

It is a subscription-based cloud model that automates the management of containers, clusters, and applications using API or web portals or container-based virtualization. Containers as a Service best streamlines the container developing and managing processes within the software architecture deployed in the cloud or on-premise environments.

How Does CaaS Work?

Let’s start with containers. It’s a logical packaging of the development infrastructure environment needed to run apps. Containers are not Virtual Machines (VM). Similar to VMs, this logical container packaging involves gross components that can allow the package to operate apps in isolation. It includes configuration files, dependencies, and libraries.

A container is a prime resource of CaaS and it is significant to build apps at speed and scale by using microservices due to the portable app components across cloud environments. And the outcomes of containerized app development process are:

• Complements multi-cloud strategy
• Development and operating cost optimization
• Cuts down overhead costs related to licensing fees

Containers as a Service automates the processes of deploying and hosting container technologies in a highly accessible cloud environment. Additionally, CaaS eliminates the complexities of ‘it runs on my machine’ problem experienced in PaaS. To discover the right cloud model, one needs to understand SaaS vs PaaS vs IaaS

Famous Orchestration Technologies Utilized with the CaaS Framework

Using the right orchestration tools depends highly on the features of cloud service providers. After getting to know some of the famous Container as a Service provides, let’s explore orchestration technologies or capabilities that can be used in CaaS:

Docker

Docker is an open source, Linux-based containerization platform to run, create, and package apps for deployment through containers. Similar to virtual Machines, Docker offers:

• Effective build and test
• OS-level abstraction along with optimum utilization of resources
• Faster application execution
• Interoperability

Few terminologies related to Docker

Docker compose network- Docker compose builds a single network for an app by default, including each and every container for the service to that default network. Containers on this single network can explore and reach every other container on the network

Docker Cloud- It's the simplest and fastest way to get the Docker into production in the cloud. It carries the development operations like Nodes (connect the Docker Cloud to existing cloud providers), Cloud repository (store your own repository), CI/CD solutions with through pipelines, and application development.

Docker Service- When the Docker Engine is in swarm mode, you need to create a service to deploy an app image. To simplify what is Docker Service, it’s an image for the microservice in context of huge applications. For instance, a database, HTTP server, or other kinds of executable program that needs to be run on a distributed environment.

Kubernetes

Kubernetes is a container platform that orchestrates networking, storage, and computing infrastructure workloads. Kubernetes extends the way to scale containerized applications without limiting the types of apps you want to deploy for leveraging the benefits of immutable infrastructure. It’s vital to gain the right understanding of Kubernetes vs Docker.
