All about CAAS (Container-as-a-Service)

Introduction TO CAAS (Container As A Services)

CAAS is a cloud services that permit and provide the platform to software developers and IT department to organize, run, deploying and scaling containerized applications. The weight of these containers are very light, movable that give a summary of software and its outpost, permits for efficient and smooth flow of deployment across several computing environments. Users can concentrate on deploying, developing application without dealing with the difficulties of infrastructure management.

This CAAS platform also consists scaling, networking, orchestration and monitoring. One of the most important examples of the CAAS platform are  Docker Swarm, Amazon ECS (Elastic Container Service) & Kubernetes.

In the other ways you can also says a cloud service model that clarify the management and deployment of containerized applications.

Wikipedia explain the concept of CAAS as a service-oriented model, where the service provider delivers the content on demand to the service consumer via web services that are licensed under subscription. The term “Content as a service” (CaaS) is considered to be part of the nomenclature of cloud computing service models & Service-oriented architecture along with Software as a service (SaaS), Infrastructure as a service (IaaS), and Platform as a service (PaaS).

Benefit Of CAAS

• The person or the users who are using container as a service, they only have to pay for those resources they are using as like scheduling capabilities, load balancing and compute instances etc. It permits the efficient utilization of resources by automatically adjusting container placement based on accessible capacity.
• It has high availability: This platform consists of the features for permits high availability, as like automated load balancing and failover and support the maintain the availability of applications even at the time when find some problems or arising the failures of hardware.
• Resources Orchestration: This platform permits for the structured using resources by automatically regulate container that is based on accessible space. The platform of CAAS has automate the deployment, scaling and organized the containerized applications. Orchestration tool help in many difficult tasks as like rolling updates, decrease the operational overhead, load balancing etc. and one of the famous orchestration tool are Kubernetes.
• Cost- Efficiency: CAAS platform optimized the utilization of resources and automating management tasks and that’s the reasons of cost saving. When we uses this platform we can save the resources for the containers it is required, and one of the important features of CAAS is it has automated scaling that will support and assure you that they are not over provisioning resources.
• Increased Application Performance: When we compared CAAS platform with others such as virtual machines, some others startup times and all around performance of applications, it have lower overhead. This will help to provide good compassion and experience.

Why CAAS is important?

One of the main benefit or the importance of CAAS is you can shift from one cloud to another and even you can go back to the server system that is physical. It also permits you to build multi and hybrid cloud system for the organizations. Now we will explain some of the other important reasons or points why CAAS (Container As A Service) is important is as follow:

• Users can use the resources as per their requirement and they can only pay for the resources they are using. This is the best benefit because it help to save the time and money of the users, they can select or choose the resources they want to work in.
• Developers gets the benefits of CAAS just by developing a application deployment and scalable container and this benefit is important to the IT teams, the reasons of its importance is it provide a container deployment service in a safe environment.

Challenges Of Using Container-as – a – Services (CAAS)

There are some challenges that CAAS has to faces and some of these are ( Networking, Security, Data Management, Cost Management, Skill Set Challenges) as follow:

Networking: It is difficult to manage network for containers and in case of large-scale deployments. In a large container or for small as well it is complex to make a communication or coordination between containers and assure for proper network segmentation and that become also challenging to handle outer access.

Security: It may arises the security risks, if the OS Kernel host is not properly isolated. It important to execute the security best practices as like utilizing reliable images, sufficient container privileges etc. It is also difficult for the security challenges to access control and privilege escalation.

Data Management: This platform container are manufactured to be stateless, but there are many application that need to stateful data and that become challenges for Container-as-a-services. In the other word you can also says that managing data backups and assuring data consistency is also become challenge.

Cost Management: It is very difficult to handle and monitor cost effectively due to the lack of visibility into the container resources. There is also a problem arises in terms of network-related cost and data transfer cost is increases mostly while serving the micro services architectures where containers are interact with each other.

Conclusion: As we journeyed through the world of Container as a Service (CAAS), this CAAS platform also consists scaling, networking, orchestration and monitoring. This platform consists of the features for permits high availability, as like automated load balancing and failover and support the maintain the availability of applications even at the time when find some problems or arising the failures of hardware.

As we conclude our exploration of CAAS, it is very clear that success lies in a holistic approach and it consist of some orchestration tools, that secure the containerized applications and navigate the cost management.
