Adopting the right cloud service type can make a world of difference to your organization. Take a look at the information below to understand the differences between PaaS and CaaS cloud services. 

What is a CaaS – Container as a Service?

CaaS or Containers-as-a-Service is a cloud service that offers container-based virtual computing to users. CaaS service providers offer their clients a full-fledged framework where they can perform deployment and management of applications, clusters, and containers. 

The CaaS model was created to let developers create, execute, and manage applications that are container-based. A CaaS model is signified by the service provider offering clusters and containers and services. These assets can be deployed in the cloud or on-premise data centers.

Developers using a CaaS model can achieve streamlined container building and deployment of applications. It is relied upon by IT departments to facilitate container-based deployment with adequate governance and security measures.

Key Advantages of a CaaS

Here are the main benefits of using a CaaS service:

Ideal to develop micro-services

CaaS enables easier development of systems and microservice architecture. A group of containers can be assigned for managing different responsibilities or separate language ecosystems during the development phase. 

Auto-Scale Applications

CaaS has a built-in features for the management of auto-scaling and orchestration. Using this model helps teams create high visibility instantly and high-availability distributed systems. CaaS also enhances collaborative development speed through rapid deployments. 

Reduce DevOps Costs

CaaS makes development more consistent while reducing operational and engineering costs.  It helps to minimize DevOps resources required for deployment management. 

Portability

In the CaaS model, the network protocols of containers can be defined and can be used for deploying applications to other environments. CaaS defined container models can easily be deployed for the purpose of cloud hosting. This server model enables containers to be deployed into a live system without delay. 

Transparency

Containerized applications deployed to a CaaS platform helps to promote transparency to system performance with tools, such as monitoring and lot aggregation. 

Top 3 CaaS Providers

– IBM Cloud Kubernetes Service – The IBM Cloud Kubernetes service refers to a managed container type CaaS service suitable for fast application delivery. It offers several key features, including horizontal scaling, smart scheduling, automation-based rollouts, and rollbacks. 

– Microsoft Azure Container Service – The Microsoft Azure Container Service is a CaaS service that enables swift development of advanced applications, including Kubernetes and Docker Swarm clusters.

– Oracle Container Cloud Service – Oracle Container Cloud Service is a CaaS service that facilitates secure and easy containerization during the development and deployment of applications. 

What is a PaaS?

Platform-as-a-Service or PaaS fundamentally involves offering a platform to clients on rent. A PaaS platform has all the tools required for development, including operating systems, infrastructure, and development tools. PaaS helps to greatly enhance web application development tasks. It is convenient as backend management tasks are taken care of, in the backend. 

A client rents a PaaS platform in the same way someone rents tools and machines to construct anything in real life. The tools and machines are owned and maintained by the PaaS service provider. 

PaaS access requires Internet connectivity and developers can choose to create a full application within a browser. Developers can work on application development, from anywhere and at any time, as the environment is not locally hosted. One point to note is that PaaS developers do not have as much control over their environments. PaaS can help to reduce overhead expenses. 

Key Advantages of a PaaS

Here are the key benefits of using a PaaS:

Pre Built Backend Infrastructure

PaaS enables fast and efficient prototyping and development through pre-built backend infrastructure and required resources. The platform offers developers the ability to access templates, tools, and libraries. It helps to reduce the time and complexity of development. 

PaaS also enables developers to perform application development with pre-built components. It reduces the amount of coding required for developing applications. Developers can use the advanced development software and provided tools that would otherwise be quite expensive to be maintained by a company. 

Faster Time-to-Market

PaaS application development is faster than methods that require developers to build, configure, and sector their platforms and backend. Using PaaS lets developers instantly access a comprehensive development environment, complete with pre-built components and code. 

Reduce Overhead Costs

PaaS lets developers from your organization access new functionalities and reduces the need for hiring external staff. Companies that use PaaS are able to reduce overhead costs as the vendor takes care of maintenance and management costs. 

Top 3 PaaS Providers

– AWS Elastic Beanstalk – AWS Elastic Beanstalk is a convenient PaaS platform for the deployment and scaling of apps and services that are created using languages, such as PHP, Java, Ruby, Python, Node.js. Docker and .NET.

– Salesforce Heroku – Heroku is a cloud PaaS platform that offers support for a wide range of programming languages. It enables developers to deploy, execute, and manage applications created with frameworks and languages like Java, Python, PHP, Node.js and Go. 

– Google App Engine – The App Engine is a managed PaaS platform from Google that facilitates the development and hosting of web applications. It offers libraries, frameworks and languages for app development. 

CaaS vs PaaS |Comparison

Conclusion 

This article explained the differences between CaaS and PaaS.

CaaS stands for Containers as a Service and it’s a service primarily used to manage containers on a single or multiple clouds. It simplifies micro services deployment, reduces cloud costs, and increases application portability levels.

PaaS stands for Platform as a Service and it allow customers to run and manage apps without server side hassles. It reduces the time to market to launch a new application and overhead DevOps costs.
