海外TECH	DEV Community	Azure Containers Services: Pricing and Feature Comparison	https://dev.to/castai/azure-containers-services-pricing-and-feature-comparison-3f3	Azure Containers Services Pricing and Feature ComparisonMany engineers get lost in Azure s services for running containers Starting with the basic Azure container services the cloud provider quickly developed other options like AKS and Azure Container Apps to give users even more options of where and how to run containers  A high number of container as a service solutions Azure offers address the needs of enterprises looking to move legacy monolithic applications to the cloud and containers decreasing application deployment and management complexity at the same time But Azure s offering spans more than that  You can find plenty of easily accessible information about Azure service offerings for running containers But there aren t many direct comparisons in terms of pricing At the end of the article we added a table of prices normalized based on compute resources That way you can compare these services like apples to apples But first let s get through the high level functionality of each service  Only interested in pricing Jump directly to the table with our calculations List of Azure compute services where you can run containersAzure s offer is so broad that it s easy to quickly get lost in all of the available options For compute Azure prepared a handy breakdown of all the hosting models for the resources your application runs on  To run a container on Azure you can choose from the following services Azure Virtual Machines deploy and manage VMs within an Azure virtual network This option should be used as a last resort if there re no other means to reach the desired customization level This will require handling additional complexity and work around managing a virtual machine on your own Azure App Service a handy managed service for hosting all kinds of web apps mobile app backends RESTful APIs or business automation processes Azure Functions this is a managed function as a service FaaS service a popular choice for serverless architectures Azure Kubernetes Service AKS is a managed Kubernetes service for running containerized applications with advanced and highly customizable orchestration functionality Azure Red Hat OpenShift yet another flavor of Kubernetes in Azure Red Hat OpenShift offers additional security and observability features out of the box but at the expense of increased price Azure Container Apps this managed service was developed on top of Kubernetes to help devs simplify the deployment of containerized applications without worrying about orchestration or infrastructure Azure Container Instances an efficient but pretty basic service for running containers in Azure You don t have to dabble in virtual machine provisioning or adopt a higher level service Azure Spring Apps a managed service created and optimized for hosting Java s Spring Boot apps Azure Service Fabric a platform for distributed systems that can run in many environments be it Azure or on premises It was developed as an Azure custom orchestration platform way before Kubernetes got mainstream Azure Batch a managed service for large scale parallel and high performance computing HPC applications As the name implies it is mostly suited for scheduled jobs Overview of Azure containers hosting optionsVirtual Machine i e running containers standalone You can adopt a DIY approach and provision an Azure VM install a container runtime on it and run your containers there But you ll have to deal with all the responsibilities around the configuration management and maintenance Going for a managed service just makes more sense unless you need full control over the underlying operating system or you re planning to customize things in a way that s not supported by any of Azure s PaaS services Running a virtual machine on your own should be used as the last tool in the box Azure App ServiceContainer hosting from App Service mainly supports web apps or APIs If that s your case and you can make it work without complex orchestration this may be a good option You don t need to deal with as much management and get many features in exchange But if your workload is anything else than a web app or API you re better off using a different service App Service doesn t let you expose your service on ports or traffic different from HTTP S The service is also a bad choice if you expect large scale bursting  Price wise App Service is only a little more expensive than standalone VMs But its basic and standard plans support only Linux containers If you re planning to run Windows you ll need the Premium V plan which can get pretty expensive Azure FunctionsIf you have a function based or short lived serverless workloads and want to use containers to develop and deploy it Azure Functions is a great pick You ll get all the features like vNet integrations triggers and bindings However if your application doesn t really fit into the serverless universe there s no point in choosing Azure Functions  What about the price of Azure Functions Custom containers often end up requiring a pricier premium or always on consumption tiers that are bound to increase your expenses It s the priciest solution when comparing resources cost per runtime But you only get charged for only what you run Great cost optimization when running infrequent requests but get extremely expensive when business grows This behavior caught many people off guardAzure Kubernetes Service AKS This is the fully managed Kubernetes service from Azure where you can still customize the machines where your workloads run A great pick for containers that need comprehensive orchestration or use advanced Kubernetes features However you still need to know your way around Ks and how deploying applications to this service works So if you aim to run a few containers AKS will bring too much complexity and overhead Pick an Azure PaaS offering instead like Azure Container Apps  What about AKS pricing The solution costs as much as the VMs where your containers run but note that some space is reserved for Kubelet running on every node Azure Red Hat Openshift ARO ARO gives you a bunch of extra management and integration services on top of Kubernetes Plus it is fully integrated into the RedHat IBM ecosystem If you could use them great ARO is your choice If you don t stick to a service like Azure Kubernetes Service This is a pricey option because you need to count in the costs for master additional infrastructure nodes and licenses Still the cost of this service is justified for enterprises who look at the additional benefits Managed observability stack out of the box It runs on aforementioned infrastructure nodes Which are automatically upscaled if when the cluster grows Advanced security and user management It s a more strict environment compared to kubernetes defaults to allow everything at the start Cluster management is abstracted by an additional OpenShift orchestration layer It prevents direct access to kubernetes API hence lowering the possibilities of what could be customized there It s a pro and con at the same time as you can do less and break less too Enterprise grade security you get top compliance operations and security with SLA of and plenty of certifications PCI DSS ISO SOC Type II and more Azure Container Apps ACA This service was designed to offer the same benefits as AKS but with less complexity to deal with If you need an orchestrator and ACA has the features you need go for it You ll remove a lot of management and maintenance tasks from your schedule This should be the first option to look at if kubernetes complexity is not required The service is also a good choice for applications that scale dynamically as it supports HTTP and KEDA scaling as well as scaling to zero If you want more control or require a feature that ACA doesn t have AKS is your next bet What about the costs ACA charges you per container runtime instead of hourly pricing of VMs where your container runs As you can see in the table below it can get pricey but you d be actually using all these resources where in kubernetes your cluster might run half empty if not configured properly Azure Container Instances ACI This solution works well if you just need to run a container and not much else ACI is also helpful for running many instances of the same container or dynamically scaling up the number of containers in use It makes sense to pick ACI over other services if you have a job based workload that runs for a limited time or an on demand service Note that ACI isn t an orchestrator If your containers need a bit more complicated orchestration or you d like to have more control over the underlying hardware ACI isn t a good choice The same is true for scenarios like private container to container networking Another limitation is container size If you need containers that are larger than cores and GB RAM ACI can t help you Another issue relates to large container images if you have them expect a slow start time that s because ACU needs to download the container image every time it s run What about the pricing As you can see in the table below ACI is slightly more expensive than an analogous VM Spring AppsA fully managed service for Spring developers which helps them to manage the lifecycle of Spring Boot applications Choosing this service would be a good choice for migrating a Spring project from self hosted infrastructure to the cloud since it wouldn t require many additional engineering expenses to make applications cloud ready Spring Apps includes monitoring and diagnostics configuration management service discovery CI CD integration and blue green deployments The service also comes with its joint engineering operation and integration from Microsoft and VMware  Service FabricThis orchestrator had one advantage it offered the Actor framework built into the platform It is a custom Azure orchestration framework which was built ten years ago If you don t know what it is and why you should use it You can achieve the same with AKS and DAPR Consider choosing it only if you require specific functionality that s only available there Or if your project is already built into this platform Otherwise Kubernetes with the help of AKS or ACA is a better alternative Azure BatchIf you re after a service that meets your specific requirements around job processing these will be more important than what you need as a container hosting platform Using containers with Batch improves the management of development and deployment Pick it if you have a job based batch workload and are looking to use containers for enhancing your development and deployment process Workloads that don t match the job based approach better run elsewhere How to pick the right Azure containers serviceConsider these aspects when reviewing the services Azure offers for containers Your knowledge of and skills around container orchestrators like Kubernetes are you ready to take on configuration tasks Do you know the Kubernetes ecosystem well If you don t Azure still offers a bunch of services you can use to run your application using this orchestrator Your familiarity with the service offering from Azure some Azure services are more complex while others do the job for you Having clarity around the service offering together with its pros and cons is a basic condition The application you re looking to containerize Azure offers a bunch of services that clearly target the legacy modernization use case The good news is that you can carry this process out gradually instead of migrating everything instantly and facing a bunch of issues The money you re willing to spend if you go through all of those services the pricing will turn out to be the deciding factor Azure makes moving applications to the cloud and containers easy but you ll always encounter some extra fees Azure provides a handy decision tree that helps to understand your options SourceThe diagram refers to two migration strategies Lift and shift where you don t make any code changes or redesign your services for the cloud just move it there  Cloud optimized you refactor an application to fully benefit from the cloud native capabilities of Azure I strongly recommend checking out Azure s materials if you need more information on the hosting models networking DevOps issues scalability availability security and other criteria There s one more aspect that s worth considering here pricing Pricing comparison for Azure containers servicesTo compare the pricing of these services let s normalize the price of each service I chose a pretty old general purpose family Dv series It s the most common machine family throughout the Azure ecosystem and is suggested as the default instance for many services Let s use the Standard D v instance as an example We ll also use the East US region and Linux OS This instance has vCPUs and GiB of RAM and costs per hour Selecting a larger instance doesn t give any price advantage per given resource  Note Normalizing Standard D v to separate CPU and RAM usage per month requires a specific formula We re working on a detailed article on how it s calculated and will share our results pretty soon Considering that the article is not read by robots we ll use pricing units per month so it s easier to comprehend for humans Service NameNormalized vCPU monthNormalized GiB RAM monthResources OverheadFinal vCPU month costFinal GiB Ram month costVirtual Machine Azure App Service   Azure Functions Azure Kubernetes Service ¹Kubelet reserved CPU Mem Optional for control plane SLA Azure Red Hat Openshift ARO Red Hat Licensing ¹Kubelet reserved CPU Mem ²Master and Infra nodes At least x Standard Ds v month Azure Container Apps Azure Container Instances Azure Spring Apps Azure Service Fabric Azure Batch This table considers costs only related to compute resources ¹For a CPU and GiB node The percentage is smaller if you use larger nodes ²ARO requires running control plane and infrastructure nodes three of both so six nodes in total Their size depends on the cluster size These nodes are upscaled vertically ARO control plane requirements SummaryThere are plenty of offerings to choose from when thinking about where to run your containers in Azure A wide range of options covers many different use cases But at the same time it s not that easy to select which one is best suited for your use case now let alone predict if your choice will work in the future Azure developed and released the above selection of services throughout the last decade More legacy services like Service Fabric have technological disadvantages compared to Kubernetes orchestration but they can t be decomposed because of existing users and systems So one has to be careful when choosing where to build a green field system to not select outdated technologies Lastly as shown in the pricing table there are big differences in how these services are priced Choosing the Functions service might look cheap at first as you pay only for how long the application runs but you might go broke once your application takes off and you achieve business success but at the same time are locked into an unreasonable cloud deal  At the same time choosing Kubernetes as a starting point for a simple application would create a lot of engineering and cost overhead which would obviously be better spent on creating value for the product you re developing At the end of the day you re the one responsible for choosing the right service because you re the only person out there who fully understands the current and possible future states of your application Wherever you run Azure containers don t forget to secure themTake a look around these Azure container services to pick the ones matching your needs and level of complexity And no matter where you end up running them don t forget about security  If you happen to pick Azure Kubernetes Service here s a handy guide to help you achieve airtight AKS security for your cluster  Download it hereReferences control plane nodes	2023-02-09 09:31:17
