The industry standard amongst IT and cloud computing-based organizations dictate the need for rapid testing, deployment, and scalability of applications. At the moment, the best option at the disposal of these companies is container orchestration. The most popular and sought-after container orchestration tool in the market today is the Azure Kubernetes Service (AKS). 

Over the past few years, cloud-based managed Kubernetes services have created highly reliable ecosystems for the deployment of containerized applications. Application containerization is a method for virtualization of applications at an OS level. This allows deployment and scaling up of applications without having to launch an entire virtual server or Virtual Machine (VM) for it.

In this article, we will talk about why AKS is a brilliant fit for application development and deployment workflows based on DevOps. Additionally, we will talk about AKS' features and their benefits.

How Does Azure Kubernetes Service Work?

Containerization with Kubernetes is a great method to simplify the resource-gathering phase for application developers. The manual processes involved in preparing a deployment ecosystem are managed by Kubernetes, taking much of the load off.

Kubernetes helps isolate each component of a deployed application in a separate container so that each of these can be scaled up individually. These containers form clusters that aggregate together to form, for instance, a microservices-based software product. AKS ensures that Azure handles all the complex aspects of resource allocation for the containerized application.

Additionally, all the other supporting services of Azure such as Anomaly Detector, Translator, or Data Science Virtual Machines can be integrated easily with the containers as and when needed. Based on Gartner Research's Solution Scorecard, AKS scores 82% because of the ease it brings for infrastructure and operations technical specialists. 

Features of Azure Kubernetes Service

A high-level definition of Kubernetes explains that it is just an organized cluster of virtual or on-premises machines. A series of computing, network, and storage resources support the containerized application as a whole. 

AKS offers a comprehensive suite of features that help manage the health and monitoring of a deployed application, in addition to various other capabilities. Some of these features are described below:

1)Environment Fit For Enterprise Solutions

A hosted Kubernetes environment for your application can be made faster and scalable as an enterprise solution seamlessly. Businesses developing containerized applications and the assigned developers have the flexibility to work on open-source projects of Kubernetes clusters. This provides for collaborative monitoring and related best practices.

2)Combination Of Nodes And Clusters

The supporting services of AKS are run on individual and clustered nodes of Kubernetes. There are node pools that contain clusters of nodes that can be grouped together and configured with the same settings as per the type of services these clusters offer. According to the volume of resources that are required for each service, the nodes can be scaled up or down.

3)Role-Based Access Control

The Azure Resource Manager supports the differentiation of services access based on identity and group membership. Role-Based Access Control (RBAC) goes one step further by making this differentiation more granular to properly control access to valuable resources in a secure manner. For the defined scope of a project, various roles with different access privileges are created with the RBAC manager tool.

4)Seamless Tools Integration

Development tools that are part of the AKS tool suite can be integrated into the project workflow to provide a fast and iterative development experience to developers. Additionally, it also provides support for automated deployment inside containers and regulatory compliance with international software development norms and standards.

5)Workload Management

Any type of workload management running in the AKS environment can be orchestrated within containers for enhanced monitoring. Additionally, workloads can be assigned to designated node clusters based on the volume of services supporting the containerized application.

Benefits Of Azure Kubernetes Service

The primary advantage for any software development firm to consider AKS implementation is that it is an absolutely free service. They can avail themselves of the varied suite of resources for setting up VMs, storage, and networking and get specifically charged for the same. 

The other benefits of AKS encompass the enhancements in building microservices apps, deploying Kubernetes clusters, as well the ease of monitoring the Kubernetes environment. These include:

1)End-to-end Security

AKS provides enterprise-grade security wherein you can track, validate, and enable compliance. This is made available across the entire Azure infrastructure as well as individual AKS clusters. Also, OS and Docker images are hardened for continuous automated deployment.

2)Simplified Configuration

The development and management of apps built on microservices architecture are simplified with streamlined and automated configuration settings. Moreover, supporting configuration features such as load balancing, disaster recovery, horizontal scaling, and access management make AKS the most sought-after option for application containerization.

3)Smooth Scaling

In addition to the node clusters of AKS, Azure Container Instances can also be scaled with ease using the configuration tool kit provided by AKS. The AKS virtual node provisions pods inside the container instances so that they start instantaneously with the available resources. Additional pods can also be scaled-out in case further scaling requires the need to integrate even more resources.

4)Multi-Tenancy

The ecosystems that are set up to support the entire software development lifecycle of containerized applications isolate production from the lower levels of development. This helps save on costs and reduce operational complexity by avoiding the deployment of entire AKS clusters for each environment.

5)Maintaining Uptime

The regular performance and operations of AKS clusters can be monitored in real-time to maintain uptime so that issues can also be resolved alongside deployment. Issues identified when the AKS clusters are monitored can be debugged immediately, so that the uptime of the application containers is maintained throughout.

Azure Kubernetes Service Is A Powerful Cloud Service

If you are looking for a powerful service for running containers efficiently in the cloud, look no further than AKS. With a cost-efficient option of paying only for the cloud resources being utilized, the expenditure of container orchestration can be reduced. 

In the long run, the time-to-market for mobile and web-based software products can be minimized drastically without increasing resource allocation. To discover how you can produce robust, scalable applications in no time, you can refer to Daffodil’s DevOps Services.
