These applications include the web, big data, infrastructural services, and more!
Challenges to the adoption of the development process with Kubernetes to developers
Without any doubt, Kubernetes is considered an ideal solution to most microservice application delivery problems. However, it also brings some technology platforms as well as setup and management-related challenges, which are unique to Kubernetes only. Kubernetes for developers is advantageous if an appropriate container orchestration solution is selected properly and challenges are addressed instantly.
In addition, the cloud systems and on-premises systems may face deployment issues when multiple departments within the IT organization are not conversant with Kubernetes. Other than that, here are some predominant challenges Kubernetes mentioned. Let’s take a deeper look:
1. Diverse Development Process
Developers need to understand that the Kubernetes platform is not replacing the traditional development process. Developers can add Kubernetes to them. Basically, software developers prefer to work in a local environment to gain full control when they know their codes and how it is going to work. However, the complication raised when using Kubernetes would be adding containers & microservices stuff because they can’t run locally and it requires Kubernetes clusters. This is where DevOps developers experience their struggle and start to lose control over the workspace and resources.
To avoid such situations, an organization can prefer a self-service approach. This can eliminate the negotiation and ops gain control over the resources and architectures instead of between developers and operations. This leads to guardrails standards and cloud-native app deployment.
2. Poor Documentation
Kubernetes platform is very modular and developers can access numerous resources. So, combining those resources to tackle a particular problem will be very difficult. In addition, as the platform is still in its evolving stage, so for developers, it’s hard to keep up with their documentation.
Developers need to search online to spot the recent or perfect example of how to do certain things; this makes it more challenging for them. However, it’s important to note that the platform is still the best place for those who are familiar with the resources and concepts.
3. YAML Files
The Kubernetes platform uses YAML files for configuration. Though YAML files are easy to read and write, the documentation of YAML is never going to be clear about how things are working. Apart from that, Kubernetes requires a lot of YAML manifest and config files which will be daunting and overwhelming for beginning developers.
To avoid this, developers can eliminate the manual creation of YAML files through automation by introducing HELM packages.
Kubernetes tools for developers: An overview of how they are useful for developers
Developers noted great improvements in the development process right after the implementation of Kubernetes tools despite all those challenges they face. Here are a few interesting features of Kubernetes that are handy for developers.
Automated Failure Management: Unexpected failures may happen at any time. So, moving from manual resource management to automated management of Kubernetes for developers leads to being more efficient.
Multi-Cloud: Kubernetes platform offers a multi-cloud strategy and supports cloud-native applications on multiple cloud platforms. This eliminates the risk of single vendor dependency among developers.
Scaling: Developers do not need to worry about scaling their applications with Kubernetes as businesses start growing. The platform scales itself automatically and efficiently to meet the application demands.
GitOps: The Kubernetes platform’s operating model is GitOps. This allows for continuous delivery of codes through automation. Also, running automated tests, and new application deployments become much easier.

2. Migrates Legacy Business Applications to Modern Cloud-technology
These days, businesses around the world prefer to move to a SaaS-based business model for delivering better consumer services. The business benefits of the SaaS model in the consumer world and Salesforce is pretty successful for enterprises in building strong business applications with siloed data. Many top-level enterprises like Netflix, Airbnb, Uber, Amazon, and so prefer this platform strategy to deliver diverse services to their consumers.
However, the SaaS model requires businesses to run or own scalable infrastructure which makes enterprises depend a lot on vendors. The Kubernetes platform and the IT ecosystem help businesses to build such capabilities to deliver excellent application components with various value-added features. In addition, the Kubernetes platform offers fidelity and an easy portability option that eliminates the risk of vendor dependability for enterprises.
3. Cloud-native Architectures for Greenfield Applications
Modern companies prefer Greenfield Applications to deliver a single view of consumer or transaction without considering the backend system and the services offered. Greenfield applications are specifically designed to work seamlessly across devices/channels. Mostly financial service, telecommunication, and business retail service providers prefer this type of application for achieving a single view of transactions/consumers. Moving such Greenfield applications to the cloud-native environment will give the ability for enterprises to deliver dynamic support in many sectors including development, handling a large number of users, operations, distribution, and so.
The Kubernetes platform is the ideal choice for businesses to handle Greenfield applications. Here are the key strategic areas that make Kubernetes the best for enterprises.

- The deployment of Greenfield applications in cloud-native architectures using Kubernetes allows enterprises to operate applications with service meshes, serverless computing, and Chaos engineering concepts.
- Prompts enterprises involved in retail, financial, and telecommunication sectors to adopt private cloud.
4. Robust Digital Transformation Via Hybrid Cloud Strategy
The public clouds often deliver panoply services which may not suit well for enterprises seeking massive scalable digital platforms. Also, the public cloud will lead toward a suboptimal situation on business flexibility and also on cost. However, moving the cloud-based deployment of legacy and Greenfield applications to a hybrid cloud strategy will benefit a lot in many aspects like cost optimization, better IT utilization, agility, and portability.
The Kubernetes platform confers business applications with cloud independence and saves a lot of costs by allowing enterprises to move with a private cloud. The hybrid cloud strategy supported by the Kubernetes platform allows Greenfield applications to deliver seamless serverless functions and microservices using DevOps processes.
5. Enhances Digital Transformation Activities
In today’s competitive business world, digital transformation is the ultimate weapon that allows businesses to survive and compete. Digitalizing the business applications will allow business enterprises to reuse them and access other services through APIs. In addition, digitalization offers to simplify operations, reduces IT costs, promotes development independently, and enables the faster release of new products.
It doesn’t matter whether those business applications are running on the public cloud or private cloud, it is best to build the application in the Kubernetes platform. This empowers the applications to run seamlessly on the same technology ever after the deployment of several versions.
Kubernetes tools for developers to improve the development process
The Deployment of Kubernetes allows business enterprises to build pods and replica sets with an official statement with proper description. Also, enterprises can control and monitor the deployment process whether it matches the desired state or not. Unlike the traditional software deployment, the Kubernetes application with an excellent deployment strategy will allow enterprises to define their application and how to create, upgrade and downgrade.
Moreover, Kubernetes helps businesses in different rolling out deployment strategies to launch application updates efficiently and avoid or minimize downtime. Take a look at the deployment strategies offered by the Kubernetes platform.
- Rolling Deployment – Replacing pods from the old version with new ones without cluster downtime.
- Recreate – Deploying new versions by terminating all existing old pods.
- Ramped Slow Rollout – Rolling out the new version replacement process by handling the old version shutting operation in
- Best-effort Controlled Rollout – Measures the maximum unavailable parameters while updating the old pods, this allows
enterprises to roll out more quickly.
- Canary Deployment – Follows a progressive delivery approach, where updating a new version serves a small pool of test users
once it is successful it will roll out to more users.
To summarize, the majority of the Kubernetes resources offer a wide range of benefits to developers for improving the application development process along with offering ease to operate could-native applications. Overall, Kubernetes is a platform that allows developers to build platforms.
