Kubernetes is open-source software that allows you to deploy and manage containerized applications at scale. Kubernetes manages clusters of Amazon Elastic Compute Cloud (EC2) compute instances and runs containers on those instances with processes for deployment, maintenance, and scaling.IT teams have several options for running containerized applications on AWS. Some organizations will opt for Kubernetes, an open source service that is the de facto choice for container orchestration, while others will want to use AWS' proprietary orchestration service instead.Kubernetes is open-source software that allows you to deploy and manage containerized applications at scale. You can choose to manage Kubernetes infrastructure yourself with Amazon EC2 or get an automatically provisioned, managed Kubernetes control plane with Amazon EKS.
Why Kubernetes is better than others : Key strengths of Kubernetes include: Scalability: Kubernetes is designed to scale effortlessly, capable of managing thousands of nodes and containers in a single cluster. Community Support: With a large and active community, Kubernetes benefits from continuous improvement, innovation, and extensive documentation.
Is Kubernetes easier than AWS
While AWS ECS restricts users to the AWS Cloud, it offers a preconfigured orchestration environment and easy integration with other AWS services. Kubernetes, on the other hand, although challenging to set up, provides absolute flexibility with its configuration and deployment.
What is better than EC2 : Other important factors to consider when researching alternatives to Amazon EC2 include price and user interface. We have compiled a list of solutions that reviewers voted as the best overall alternatives and competitors to Amazon EC2, including Google Compute Engine, DigitalOcean, Azure Virtual Machines, and Vultr.
Moreover, if your application stack is simple, not distributed, or doesn't require advanced features like auto-scaling, self-healing, and service discovery, Kubernetes might be an overkill. Its complexity and overhead may lead to more problems than solutions.
The primary benefits of container are speed, consistency, density, resource efficiency, and portability.
Why use Kubernetes on AWS
Kubernetes manages clusters of Amazon EC2 to compute instances and runs containers on those particular instances with processes for deployment, maintenance, and scaling. Using Kubernetes, you can run any containerized application using the same toolset on-premises and within the cloud.Disadvantages: Despite its numerous advantages, Kubernetes also poses some challenges: 1. Complexity: Kubernetes has a steep learning curve and requires expertise in containerization, networking, and distributed systems, making it challenging for inexperienced users to deploy and manage effectively.If you want to learn more about the infrastructure as code, you should start with some basics AWS, then terraform. If you want to learn more about how to deploy your app, you should learn some basics of docker then K8s. So, you can start with docker->K8s->Cloud"AWS"->Terrraform.
Cost: ECS/EKS clusters can be more cost-effective than EC2 Auto Scaling groups because they offer better resource utilization. Containers can be packed more densely on a single EC2 instance, reducing the number of instances required to run the same workload.
Is EC2 still relevant : Update (August 23, 2023) – The retirement announced in this blog post is now complete. There are no more EC2 instances running with EC2-Classic networking.
Is Kubernetes still relevant 2024 : In the 2024 Kubernetes Benchmark Report, Fairwinds analyzed more than 330,000 workloads, reviewing data from hundreds of organizations. The latest report shows Kubernetes users have significantly improved workload efficiency and reliability, though areas for improvement remain.
What is bad about Kubernetes
Hard learning curve. Kubernetes is definitely not for IT newcomers. To start with it, you have to be closely familiar with microservices-based architecture, containers, networking, cloud-native technologies, continuous delivery and integration practices, infrastructure as code, and more.
Scalability: Managing increasing demands of the application workload is complex and time-consuming. Amazon EKS offers the advantage of leveraging Kubernetes, which provides efficient orchestration and auto-scaling capabilities reducing manual efforts and ensuring optimal performance.If you want to learn more about the infrastructure as code, you should start with some basics AWS, then terraform. If you want to learn more about how to deploy your app, you should learn some basics of docker then K8s. So, you can start with docker->K8s->Cloud"AWS"->Terrraform.
What is the biggest benefit of using Kubernetes : Kubernetes makes it easy to realize the promise of multi-cloud environments. Since it runs indiscriminately in any environment, it can efficiently scale environments from one cloud provider to another – and even from on-premises to cloud – without functional or performance losses.
