Learning Container as a Service Architecture

Let us start by defining what CaaS stands for in cloud computing. A container-as-a-service is a cloud function that allows program engineers and IT department to use container-based virtualization to upload, arrange, scale, run, manage and stop containers. CaaS is a highly sought-after provider for businesses. It is the provision of Containers to businesses at a reasonable cost by Cloud service providers. Containers, like virtual machines, are virtual spaces in which designers can code and run applications. The distinction here is that containers are not dependent on the base operating system. This enables developers and testers to work on the code without the numerous issues caused by different operating systems. Cloud services offer containers to businesses as a service on their Cloud infrastructure, thus CaaS.

For many years, telecom companies, cloud service providers and system integrators have provided infrastructure-as-a-service (IaaS) to business clients. Many customers want new services from these providers as information technology (IT) develops and becomes more application-centric, particularly CaaS and platform-as-a-service (PaaS).

So far, policy integrators have mainly provided technical support to their clients accompanied by fully run services for onsite Kubernetes installations which clients originally used for pilots before becoming the production platform for their corporate digitalization initiatives.

Some corporations prefer a hosted CaaS cloud service as part of this transformation instead of retaining the new platform in their data center. The service provider of choice has two options for dealing with this situation:


● Resell a low-margin managed service from a hyper scaler
● Create its own hosted service to increase its wallet share

What Are the Main Advantages of CaaS?

Containers have a number of advantages according to industry experts. They are not a perfect solution, but far superior to many others. Containers are the result of software evolution which began with the development of Virtual Machines. IT professionals use containers because they have distinct advantages over comparable offerings. They are listed below.


● Platform Agnostic
● Resource Friendly
● Better Data Security and Protection
● Agile Functioning
● Easy and Quick Scalability
● Easy to Create and Close
● Easy Portability
● Simplified Operation

Given that 96 percent of CNCF Survey 2021 respondents said they were using or assessing Kubernetes. The logical choice for service providers is to construct a container architecture. Although cloud-native systems are all open-source initiatives, there are several reasons service providers should give a second thought before relying solely on open-source projects to build a service.


● Integration:It requires numerous additional components such as networking, load balancers, storage, monitoring, CI/CD pipelines, logging and so on. It is difficult and time-consuming to integrate and manage these components.
● Support: It is not a good idea to rely on support from the community for escalations, particularly if they want to provide SLAs to their final users.
● Security: Most businesses require complex security measures as well as authorization and authentication procedures that take time to create. They should keep using the open-source distribution.

Several market alternatives tackle this issue while remaining compatible with the open-source Kubernetes project. However, as a service provider, choosing the base technology is only the initial step. They must also choose deployment options, monitoring, security, backup and availability capabilities, as well as assimilation with billing and other back-office processes.

One of the most crucial choices is how a service provider will run OpenShift for their clients. The most popular architecture is for each customer to have their own OpenShift cluster. They can provide this service to their customers in a variety of ways, including bare-metal and virtualized.

Launching OpenShift bare metal has authorization advantages for massive installations, and it requires numerous physical hosts per system and may be too expensive in most cases. Small deployments are possible when OpenShift is virtualized. It also provides the standard benefits of virtualization, such as increased control-plane repetition via vSphere HA and the abstraction of OpenShift from the underlying hardware, consisting of drivers and firmware.

VxRail provides service providers with a steady and efficient platform to start offering OpenShift as a service. Various independent OpenShift implementations can use the same physical hardware, and clients can start slow and scale up as there is more development of applications. VxRail automation allows the service provider to handle all hardware upgrades and platforms without worrying about how they will affect OpenShift.

Conclusion

Containers are popular among industry professionals for a reason. They provide benefits that far outweigh any disadvantages they may have. Its ease of use, resource friendliness, agility and portability make it a clear favorite in the coding community.
