Are you looking for the best Kubernetes alternatives? If yes, you have stumbled upon the correct webpage.
While Kubernetes is a great container orchestration solution, it is not the only option. There are some better alternatives out there.
In this article, we will talk about some of the best Kubernetes alternatives you can use.
So, without any further ado, let’s get started –
Kubernetes – What do we know about it?
Kubernetes, also known as K8s, is an open-source container orchestration solution offered by Google. Being an open-source tool, developers can use it for free, which is one of the main reasons it is so popular.
The tool lets you automate the deployment and management process of native cloud applications using cloud platforms or on-premise infrastructure.
Kubernetes is unique and highly resilient, supporting zero downtime, container self-healing, scaling, rollback, and other capabilities.
Even though Kubernetes is one of the best container orchestration solutions, it has some drawbacks that make people look for alternatives.
For example, Kubernetes is too powerful for most small to mid-level projects. It is suitable for massive-scale development, but if you don’t have a high-scale development need or do not have a distributed architecture, Kubernetes would not be a good choice.
Kubernetes is quite complex and has a steep learning curve. Even if you are a developer or have experience in DevOps, you must spend some serious time learning this tool.
Besides that, even though Kubernetes is an open-source tool, it requires you to set up a large-scale computing environment, increasing the cost of deployment and management of Kubernetes.
These are a few reasons people look for Kubernetes alternatives. The good thing is that plenty of tools designed for specific needs can be used to replace Kubernetes. Below, we have reviewed some of the best ones.
We have categorized these alternatives into deployment solutions, such as Container as a service (CaaS), Function as a service (FaaS), managed services, and more.
Best Kubernetes Alternatives – Our Pick👌
Let’s start with Container as a service Kubernetes alternative –
1. AWS Fargate – Serverless computing for containers
AWS Fargate entered the market in 2017, but despite being a relatively new player, AWS offers some great features that make it a perfect Kubernetes alternative. The best thing about AWS Fargate is that it lets you launch containers without servers.
This serverless compute engine runs containers using the Amazon Elastic Container Service (ECS).
It offers a very flexible computing model that allows developers to focus on developing, designing, and building the application instead of getting into configuring a cluster or selecting Amazon EC2 instances.
With this Kubernetes alternative, users don’t need to worry about provisioning, configuring, and scaling clusters for virtual machines.
This eliminates the need to optimize cluster packing or choose the server types.
All these things increase the ability to speed up the deployment process of applications while enhancing overall security and performance.
However, AWS Fargate has some drawbacks. For example, AWS Fargate is quite expensive, and since you will be paying according to the CPU and memory resources usage, it is pretty challenging to predict its cost.
Moreover, it is not that user-friendly, and to use it, you will need to know about certain other services.
Besides that, one biggest deal-breaker is that it doesn’t boast the orchestration capabilities, suitable only for small, standalone services, microservices applications, and other processes that do not require interaction between components.
2. Azure Container Instances
Azure Container Instances is another excellent and trendy solution that lets developers deploy containers without worrying about provision, server management, managing infrastructure, or anything else.
Azure Container is similar to AWS Fargate; instead of Amazon ECS, it uses Microsoft’s Azure public cloud to host all your containers.
Since you don’t need to manage the infrastructure and servers, Azure Container Instances make creating containers on demand extremely easy and fast.
Creating containers using Azure Container Instances is relatively fast and easy. You can create a container by using the Azure portal or the Azure CLI.
Once your container is created, Microsoft will automatically configure and scale computing resources according to the requirements.
This Kubernetes alternative provides a hypervisor isolation function that lets you run each container group without sharing kernels. This gives you VM-level security while preserving lightweight container speed and efficiency.
ACI supports Windows and Linux containers, which might not be a big deal for many but is still something you can consider. It also allows you to use images from public container registries such as Docker Hub, Azure Container Registry, and more.
The drawbacks of ACI are pretty similar to AWS Fargate. For example, ACI is not suitable for processes requiring regular interaction between components or large-scale computing environments.
It is only ideal for standalone services or microservice applications.
3. Google Cloud Run
Google Cloud Run is another Container as a service solution that lets you run stateless containers that HTTP requests can automatically scale.
It is a perfect tool for running all-in-one software bundles such as a Flask app and open-source software.
All the containers that you create will be hosted on Google Cloud servers. Since there is no infrastructure to manage, developers and the team will be free to focus entirely on writing applications rather than worrying about provision, scaling, or more.
Using Google Cloud Run is quite simple and easy. You must provide your container location, and Google Cloud Run creates a container with your pre-built app and deploys it. However, there are a few things that you need to keep in mind.
For example, the logic should be stateless, and you must specify the combination of memory vs. CPU and a few other things.
The best thing about Google Cloud Run is that, unlike other CaaS options out there, Google Cloud Run is capable of managing complex applications that have multiple endpoints.
This makes Google Cloud Run a better Kubernetes alternative for people who want to create complex applications without getting into the task of managing infrastructure.
While services like Google Cloud Run make it extremely easy to split tasks into different pieces of logic, these are not good for situations where you have to design one container that can handle everything.
This is the limitation of almost all CaaS, not only the Google Cloud Run.
So, these were the three best CaaS Kubernetes alternatives. Now, let’s see some of the managed services that can be used as Kubernetes alternatives –
4. Google Kubernetes Engine (GKE)
When discussing managed services that can be used as Kubernetes alternatives, the first name that comes to my mind is Google Kubernetes Engine.
Google Kubernetes Engine is an excellent choice for those who don’t want to invest in cloud infrastructure or work in a multi-cloud environment.
The reason Google Kubernetes Engine is my favorite Kubernetes alternative is that Google is the original developer of Kubernetes.
Not only that but Google is highly involved in Kubernetes’ development. In addition, Google was also the first to introduce a managed Kubernetes service.
These are a few reasons why Google Kubernetes Engine is highly popular and regarded as the most mature Kubernetes service.
Another good reason to use Google Kubernetes Service is that when you use GKE to create a cluster, you can access other advanced Google Cloud Platform management features.
GKE lets you use Google Cloud Build to design container images from various source code repositories. In addition to that, you can store all your container images in Google Container Registry.
Another good thing about GKE is that it automatically upgrades the control planes and scales the cluster’s node instance count.
It also boasts an automatic node health repair function that ensures your nodes will be healthy and available without any issues.
GKE also offers the most available versions of the three managed services. Plus, you can subscribe between three release channels – Rapid, Regular, and Stable. Each channel lets you choose between update churn and features and the stability of the version.
With Google Anthos, you can use GKE on-premises and other public cloud services like AWS.
You can even use a container-optimized OS for the end nodes to ensure security, stability, and performance. Sadly, only one zonal cluster is free, but that is not a deal-breaker, especially from a managed Kubernetes service.
5. Azure Kubernetes Service (AKS)
Initially, Azure offered this service as Azure Container Service (AKS), where they used to offer support to Apache Mesos, Docker Swarm, and Kubernetes.
However, after seeing the massive popularity of Kubernetes, Azure replaced Azure Container Service with solely dedicated to Kubernetes Azure Kubernetes Service in 2018.
One of the good things about Azure Kubernetes Service is that it doesn’t require you to pay for the Control Plane, making it relatively cost-effective, especially compared to other managed alternatives. On top of that, it integrates very well with all types of Microsoft products.
So far, Azure Kubernetes Services has been the fastest to release all newer versions of Kubernetes and their patches.
However, it is not fully automatic, meaning you must manually update some cluster components to a newer version. Azure is working on a fully automatic solution to fix this, but that is still in development.
However, Azure Kubernetes Service does have an automatic node health repair function. This is great for maintaining nodes’ health, availability, and stability. As we already told you, the Control Plane is free, and you only have to pay per node.
What impressed me the most about Azure Kubernetes Service is that it offers an excellent developer environment.
For example, you can use the Kubernetes extension in VS Code to deploy your codes to Azure Kubernetes Service directly. Further, you can also use the Bridge to connect with AKS.
It allows you to develop, debug and run your codes directly in a development machine, as this machine was a part of your cluster.
This removes the need to replicate dependencies to your IDE or development machine.
6. Amazon Elastic Kubernetes Service (EKS)
Amazon Elastic Kubernetes Service is one of the most popular and widely used managed Kubernetes services out there, according to a survey conducted by CCNF.
This service offers deployment options on both EC2 and Fargate, meaning you can even use it on-premises and on Amazon infrastructure and other public clouds.
Amazon Elastic Kubernetes Service simplifies and automates the deployment and management process of Kubernetes clusters.
This service is based on the latest released open-source Kubernetes tool, meaning you will never lack any of the features and benefits of Kubernetes. Additionally, EKS is fully compatible with the Kubernetes ecosystem.
However, one major drawback of Amazon Elastic Kubernetes Service is that it has the least amount of pre-configured solutions.
This includes the most manual steps to upgrade cluster components and configure your clusters. Plus, it lacks automatic node heath repair functionalities.
EKS fully manages the Control Plane and can scale master nodes as needed. This ensures high availability and options by deploying among multiple availability zones. EKS also boasts AWS GovCloud, meaning it has government cloud support.
This Kubernetes alternative helps you manage a wide range of Kubernetes setup and maintenance tasks, such as the replacements of unhealthy instances, Kubernetes updates, and more.
Besides that, logging and monitoring can also be easily configured in the CloudWatch Container Insight tool. However, this tool still needs some improvement as it is not intuitive.
Even though EKS is a popular and widely used Kubernetes-managed service, it has many drawbacks. For example, it is costly compared to Azure Kubernetes Service, costing you $0.10 per cluster per hour, which is relatively high.
Plus, it requires many manual tasks, such as installing upgrades for the VPC CNI, Calico CNI, and more.
Unlike AKS, this service doesn’t even have any extensions for IDEs, such as VS Code which can be used to develop EKS codes.
So, these were the three best-managed services that you use as alternatives. You can also opt for the Platform as a Service (PaaS) option for Kubernetes replacements.
Below we have shared some of the best PaaS Kubernetes alternatives –
7. OpenShift Container Platform
OpenShift Container Platform is a commercialized tool based on an open-source project initiated and managed by Red Hat. Also known as Red Hat OpenShift, this tool was previously known as Open Hat Origin. It is a powerful containerization tool offered by Red Hat as a flagship software.
OpenShift is known for its top-notch security, in-built monitoring features, centralized policy management, and many other compatibility tools and features. As a developer, you can use it to create, test, and deploy applications directly on the cloud.
This platform uses Docker-style Linux containers, Red Hat Enterprise Linux, and Kubernetes. This offers a superb combination of functionalities, features, and compatibility.
OpenShift also supports a wide range of programming languages, including Java, Python, PHP, Go, and Ruby, allowing you to write codes and scripts in the language you are most familiar with and comfortable with.
One of the main reasons you should use OpenShift is its security. It has way more strict security policies than any other Kubernetes alternatives. For example, its policies restrict users from using container images and prevent developers from running containers as root.
Additionally, OpenShift uses DeploymentConfig to update pods. It does this by using internal controls but does not support concurrent updates.
This is one of the drawbacks of OpenShift, but it is installable on a handful of platforms, such as Red Hat Linux, Fedora, and CentOS.
Compared to Kubernetes, OpenShift is relatively simpler to use. You get a login dashboard where you can easily access various features to perform various tasks. It further supports CI/CD pipelines, making deploying your apps easy on OpenShift.
Kubernetes vs openshift:-
Popular open-source container orchestration platform Kubernetes can be installed in on-premises, cloud, or hybrid environments. It offers fundamental administration capabilities and decent security, but more setup is needed to achieve enterprise-level security.
On the other hand, OpenShift is Red Hat’s for-profit Kubernetes-based product. It is a platform for container applications that offers extra administration tools and capabilities for simpler management and built-in security features for enterprise-level security.
OpenShift offers paid support solutions for enterprise-level assistance along with an installer for simple installation.
Here’s a table comparing Kubernetes and OpenShift:-
|Origin||Developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF)||Developed by Red Hat|
|Architecture||Container orchestration platform that provides a foundation for building and deploying containerized applications||Kubernetes-based platform that adds additional features and functionality on top of Kubernetes|
|Deployment||Can be deployed on any infrastructure including on-premise, public cloud, and hybrid cloud environments||Can be deployed on any infrastructure including on-premise, public cloud, and hybrid cloud environments|
|Ease of Use||Requires a higher level of technical expertise to set up and manage||Provides additional features and tools to simplify installation, management, and monitoring|
|Features||Provides basic container orchestration features such as scaling, load balancing, and service discovery||Provides additional features such as integrated container registry, integrated CI/CD pipeline, automated security patches, and multi-tenancy|
|Community Support||Has a large and active open-source community with a large number of third-party tools and plugins available||Has a smaller but still active open-source community with additional enterprise-level support and resources from Red Hat|
|Cost||Free and open-source||OpenShift has both a free, open-source version (OKD) and a paid enterprise version with additional features and support|
|Security||Provides basic security features such as RBAC and network segmentation||Provides additional security features such as integrated security scanning and compliance reporting|
|Customization||Offers a high level of customization and flexibility for organizations that want to build their own infrastructure||Provides a more structured and standardized approach to container orchestration with less flexibility for customization|
Rancher is another PaaS Kubernetes alternative. It is also open-source and allows you to run containers across multiple environments, such as on-premises and public clouds.
It offers a high-quality web interface that makes the deployment process much faster and more convenient than Kubernetes.
Rancher has an in-built container management tool. Along with that, it lets you use any other container manager. Let’s say you want a feature that isn’t available in Rancher.
In that scenario, you use other container management tools like Docker Swarm or Kubernetes on top of Rancher. Rancher also makes it quite simple and easy to configure these tools.
Besides that, Rancher supports the integration of a bunch of applications that can be easily deployed with a few mouse clicks.
These integrations of other container management tools and a catalog of ready-made applications make it extremely easy to manage complex environments.
Further, Rancher captures computing resources from other private and public clouds and lets you seamlessly deploy Kubernetes resources on them.
The key features of Rancher include container load balancing, cross-host networks, multi-tenancy, persistent storage services, multi-cloud management, user management, built-in security for Kubernetes clusters, and more.
However, Rancher has some drawbacks too. For example, it is not a 100% ready-made solution like the OpenShift container or other services mentioned in this list.
You can only deploy sources from Docker images, and you will also have some limitations with the database scaling.
I would like to mention that even though OpenShift is relatively easier than Kubernetes, it requires some container technology knowledge. You at least need to be able to create Docker images to deploy your applications.
So, we have covered some Container as a service (CaaS), Platform as a service (PaaS), and managed alternatives. Still, some lightweight orchestrators are also available that can be used as alternatives to Kubernetes.
Kubernetes vs rancher:-
here’s a comparison table between Kubernetes and Rancher:-
|Deployment||Kubernetes uses YAML files to deploy apps.||Rancher uses a web interface to deploy apps.|
|Scalability||Kubernetes can scale up to 5000 nodes.||Rancher can scale up to 1000 nodes.|
|Management||Kubernetes requires more expertise to manage.||Rancher provides a more user-friendly management interface.|
|Ease of use||Kubernetes has a steeper learning curve.||Rancher is easier to use for beginners.|
|Compatibility||Kubernetes can run on any cloud platform.||Rancher is primarily designed for use with Kubernetes.|
|Community Support||Kubernetes has a large community and ecosystem.||Rancher also has a community, but it is smaller compared to Kubernetes.|
|Customization||Kubernetes offers greater flexibility in customization.||Rancher has fewer customization options.|
Below we have shared some of those lightweight orchestrators –
9. Docker Swarm
Docker Swarm is a platform that lets you build containerized applications, similar to Kubernetes.
It is even one of the most popular and widely used alternatives. It lets you design and manages Docker engine clusters on top of the Docker platform.
Swarm is a feature that lets you create and manage clusters and schedule Docker Engines. You need to enable a native feature of Swarm in Docker. However, once the Swarm mode is enabled, you can use the Docker CLI to create, deploy and manage your cluster.
Docker Swarm makes it very easy to coordinate containers and assign tasks to container groups. On top of that, it also checks the health of the containers, manages their life cycles, offers redundancy and failure in the situations of a node failure, and more.
It also helps you perform rolling updates and scale containers according to load and needs. This makes the deployment and scaling process much faster compared to Kubernetes. However, the automatic scaling function still needs some improvement, and its capabilities are less mature.
Docker lacks a dashboard, making it difficult and confusing for a beginner. However, you can always install third-party tools to eliminate this issue.
It further uses the DNS to distribute the requests to service names. This automatically assigns service addresses, but the user can also select specific ports to run the service.
While Docker is a good Kubernetes alternative, its functionalities are pretty limited. The Docker community is also far smaller than Kubernetes.
But the smoother learning curve and the Docker Engine make it a perfect choice for inexperienced operators.
Kubernetes vs docker swarm:-
While Docker Swarm is easier to use and lighter than Kubernetes, it is frequently regarded as more capable and feature-rich.
The exact requirements and objectives of the project or organization will ultimately determine which option is best.
|Orchestration||Kubernetes has a highly sophisticated orchestration system with powerful scheduling capabilities and robust load balancing.||Docker Swarm is a simpler orchestration system that is more straightforward to set up and manage, but lacks some of the advanced features of Kubernetes.|
|Scalability||Kubernetes is highly scalable, with the ability to manage thousands of containers and nodes.||Docker Swarm is also scalable, but may not be as well-suited for very large deployments.|
|Networking||Kubernetes has a highly configurable networking system with support for many different networking plugins.||Docker Swarm has a simpler networking system, but still supports a range of networking options.|
|Security||Kubernetes has many built-in security features, including RBAC, pod security policies, and network policies.||Docker Swarm also has built-in security features, but may not be as extensive as Kubernetes.|
|Community||Kubernetes has a large and active community, with many resources and plugins available.||Docker Swarm has a smaller community, but is still actively maintained and supported.|
|Compatibility||Kubernetes is highly compatible with many container runtimes and cloud platforms.||Docker Swarm is generally only compatible with Docker containers and Docker-based cloud platforms.|
|Learning Curve||Kubernetes has a steeper learning curve, but provides more advanced features and scalability.||Docker Swarm is simpler to learn and use, but may not be as well-suited for complex deployments.|
Lastly, we have Nomad on our list. Nomad is a container orchestration tool by HashiCorp that lets you deploy, manage and scale workloads across multiple cloud platforms. It is a simple and flexible workload orchestration tool that is comparatively easier to learn and use.
It offers a shared pool of infrastructure from various platforms, such as on-premises and public clouds, that can be shared between multiple applications.
Instead of offering specialized container orchestration and automation tools, Nomad focuses on cluster management and container scheduling through bin-packing and optimized resource utilization.
Nomad clusters use Consul for the configuration and management of cluster services. It automates the workload schedule by following an evaluation process to change the node’s state to match it with the desired state of the job.
It also checks nodes for emergent states and boasts self-healing functionalities. If the state of a node fails, it triggers a new evaluation, and after that, Nomad tries to fix the emergent state with the system’s desired state.
This helps in restarting the application and recovering data in situations of failure.
Nomad offers device plugins, multi-region federation, GPU support, multi-cloud management, integration with the HashiCorp ecosystem, scalability to up to clusters of 10,000 nodes, and more. This seems quite promising.
However, it lacks some functionalities regarding end-to-end container orchestration and flexible workload support. But overall, I would say HashiCorp Nomad is a worthy choice.
Kubernetes vs nomad:-
Compared to Nomad, a more straightforward platform intended for smaller-scale, simpler applications, Kubernetes is more potent and complicated and best suited for large-scale, complex applications.
The application’s particular demands and requirements, as well as the resources and management skills available for the platform, will determine which of the two platforms is best.
here’s a table comparing Kubernetes and Nomad:-
|Orchestration||Kubernetes is a popular container orchestration platform that automates the deployment, scaling, and management of containerized applications.||Nomad is a modern, flexible, and powerful cluster manager that can schedule and manage any kind of workload, including containers, VMs, and non-containerized applications.|
|Scalability||Kubernetes is highly scalable and can support large, complex applications with thousands of containers.||Nomad is also scalable and can handle large workloads, although it may not be as well-suited as Kubernetes for extremely large or complex deployments.|
|Deployment||Kubernetes provides extensive deployment options, including rolling updates, blue-green deployments, canary deployments, and more.||Nomad also supports rolling updates and canary deployments, but its deployment options may not be as extensive as Kubernetes.|
|Architecture||Kubernetes has a master-worker architecture, with a master node that manages the cluster and worker nodes that run applications.||Nomad has a simpler architecture than Kubernetes, with a single binary that can be run on any machine to create a cluster.|
|Community||Kubernetes has a large and active community, with extensive documentation, tutorials, and third-party tools and integrations.||Nomad also has a growing community, although it may not be as well-established as Kubernetes.|
|Complexity||Kubernetes is a complex platform with a steep learning curve, and it may require significant resources to set up and maintain.||Nomad is generally considered to be simpler and easier to use than Kubernetes, although it may not be as feature-rich.|
|Use Cases||Kubernetes is often used for large-scale, complex applications with high availability and scalability requirements.||Nomad is often used for smaller, simpler applications or for heterogeneous workloads that include both containers and non-containerized applications.|
Kubernetes dashboard alternatives:-
You can manage and monitor your Kubernetes cluster’s resources using the web-based Kubernetes dashboard interface.
Here are a few possibilities you might take into consideration if you’re seeking Kubernetes dashboard substitutes:-
kubectl:- Using a terminal window, you can manage and monitor your cluster’s resources with kubectl, a command-line interface (CLI) for Kubernetes.
Heptio Ark:– Providing a command-line interface and API for controlling and backing up your cluster and its resources, Heptio Ark is a disaster recovery and data migration tool for Kubernetes.
K9s:- K9s is a terminal-based Kubernetes dashboard that gives text-based access to your cluster’s resources and allows you to inspect and manage them.
KubeApps:- For deploying and maintaining applications on Kubernetes, there is a web-based platform called KubeApps. It offers a dashboard where you can examine and manage the resources used by your applications.
Rancher:- Rancher is a platform for managing containers that offers a web-based dashboard for controlling and monitoring your Kubernetes clusters and their resources.
The Kubernetes dashboard can be replaced in several ways, and these are just a few examples. The ideal alternative for you will rely on your particular wants and requirements among the many other possibilities accessible.

However, there may be costs associated with using third-party tools and services.||OpenShift is a commercial product, and there are costs associated with using it. However, there is also a free version of OpenShift available for personal use.||Docker is open-source software, so it is free to use. However, there may be costs associated with using third-party tools and services.|
Kubernetes vs docker:-
With sophisticated capabilities like automated scaling, built-in load balancing, and container networking, Kubernetes provides a more durable container orchestration and management platform.
While having minimal administration and networking capabilities, Docker, on the other hand, focuses exclusively on containerization and deployment. However, since Kubernetes and Docker are open-source and free, developers and businesses of all sizes can use them.
