Since its inception, Kubernetes has transformed the way software developers create and deploy applications. This widely adopted technology has naturally caught the attention of Data Scientists.
They have realized that certain features of Kubernetes can optimize and support the data science workflow. Discover why it’s a highly useful tool for Data Scientists, now almost indispensable…
What is Kubernetes ?
Kubernetes is an open-source platform designed to manage containers and clusters from a single, centralized interface. It allows you to deploy containers across various environments, including the cloud, virtual machines, and physical machines, to create a network of virtual machines.
With Kubernetes, one or more containers can be placed in a “pod,” which is the smallest deployable unit. The platform enables application scaling based on workload, and application components can be moved between systems, providing scalability.
The key advantages and features of Kubernetes include the automation of manual container hosting and deployment processes, self-monitoring of containers and nodes, horizontal scaling, and flexibility in terms of environments.
Kubernetes and Data Science
The extensive user community of Kubernetes continually develops new features for the platform, many of which are highly beneficial for Data Science. This includes declarative deployments, comprehensive monitoring capabilities for each system component, continuous integration, and flexible service routing.
Indeed, Data Scientists face numerous challenges similar to those encountered by software engineers. They must conduct numerous experiments and perform repetitive tasks.
Additionally, various metrics need to be tracked and monitored, access and credentials managed, and scaling made easy. In this regard, Data Scientists can leverage several Kubernetes features.
Batch job execution can be used for data processing and testing, as well as for training and deploying models commonly found in Machine Learning pipelines.
Microservices architectures offer a simplified application structure based on modularity, making it easier to modify and secure software components.
Moreover, declarative configurations simplify model creation across platforms by illustrating connections between services. The ability to create customized workflows for container management is highly valuable for creating dedicated workflows for each experiment.
Machine Learning engineers can also benefit from Kubernetes. For example, the Kubeflow project enables them to run frameworks like JupyterHub, Tensorflow, PyTorch, or Seldon under Kubernetes, facilitating the development of truly portable workloads.
Lastly, integration with Spark allows for the creation of a Spark driver within a Kubernetes pod. This driver creates “executors” connected to Kubernetes pods, executing applications seamlessly.
The main advantage of Kubernetes: container management and autoscaling
For the smooth operation of a production environment, the developer must ensure the proper functioning of these containers. A task that can become complex when managing dozens or even hundreds of them. Fortunately, Kubernetes is here!
With its features, Kubernetes minimizes human intervention. It also enables auto-scaling, meaning it automatically scales up or down applications as needed based on resource demands. This helps reduce costs, accelerate update installations, and enhance data security. It’s also a valuable time-saver for developers who no longer need to manually manage workflows, allowing them to focus on other tasks and be more productive.
Kubernetes features, a revolution for Data Science
Seeing the potential of Kubernetes, Data Scientists have realized that some features of the container orchestration tool would be particularly useful in data science.
The vast user community of Kubernetes continually develops new features for the platform, many of which are used by Data Scientists.
This includes, for example, declarative deployments, comprehensive monitoring capabilities for each system component, continuous integration, and flexible service routing.
In their daily work, Data Scientists face many challenges similar to those encountered by software engineers. They must conduct numerous experiments and perform repetitive tasks.
Likewise, Data Scientists must diligently monitor various metrics and the databases they use. They also need to manage access and credentials to data warehouses and ensure that scaling goes smoothly. These features can be greatly facilitated by Kubernetes!
Data Scientists can, for example, take advantage of continuous batch job execution for data processing and testing, as well as for training and deploying Machine Learning models.
On the other hand, the microservice architectures offered by Kubernetes provide a simplified application structure based on modularity.
In a microservices architecture, containers are ephemeral. When they are no longer up to date or become corrupted, the system removes them, and new containers automatically take their place. This helps maintain service availability.
Moreover, declarative configurations make it easier to create models across platforms by illustrating connections between services. The ability to create custom workflows, simplifying container management, is also very useful for creating dedicated workflows for each experiment.
By using native Spark integration with Kubernetes, Data Scientists can also access a self-service Big Data analytics platform and analyze data for research and development purposes.
The use of container orchestration is also useful for natural science research teams. Containers allow the replication of scientific tests, making it possible to replicate test results on different environments and devices.
A container orchestration tool like Kubernetes is therefore very useful in Data Science due to its extensibility and flexibility. It also allows for the adjustment of Machine Learning workflows and deployment on a wide variety of environments.
Kubernetes makes it easy to deploy Machine Learning workloads
Machine Learning engineers can also benefit from Kubernetes. The Kubeflow project, for instance, allows them to run frameworks like JupyterHub, Tensorflow, PyTorch, or Seldon under Kubernetes. With Kubeflow, Machine Learning engineers can easily import their projects into Kubernetes and take advantage of all its benefits.
Furthermore, integration with Spark enables the creation of a Spark driver within a Kubernetes pod. This driver creates “executors” connected to Kubernetes pods and executes applications.
Kubernetes is, therefore, a valuable ally for Data Scientists and Machine Learning. It enables the development of ML pipelines to a production level. Moreover, an increasing number of companies have Kubernetes clusters that they use to expose services. Data teams can thus join these existing clusters and offload the infrastructure management aspect, allowing them to focus more on creating dedicated Machine Learning pipelines.
How can Kubernetes be used in Data Science?
Data Science teams use Kubernetes for various applications. For example, it’s possible to deploy models for online inference.
Scaling an application to handle increased load is simplified by Kubernetes through model exposure. You can create a deployment and then expose it for use by others. Kubernetes will automatically balance the traffic, respecting the configuration set by the Data Scientist.
Another example of a use case is R&D data analysis. By using native Spark integration with Kubernetes, Data Scientists can access a self-service Big Data analytics platform.
The use of container orchestration is particularly useful for natural science research teams. Containers allow the replication of scientific tests, making it possible to replicate test results on different environments and devices.
In conclusion, Kubernetes is highly valuable to Data Scientists due to its extensibility and flexibility, which enable the adjustment of Machine Learning workflows and deployment across a wide range of environments. Among other tools in Data Science, you can also explore SQL and the Python language…
