Those who deal with cloud services and technologies, or who are involved in the machine learning and data science communities, frequently come across the Kubernetes platform. As the amount of use cases expanded and the requirement for flexibility and dissemination increased, this technology rose to the forefront of the machine learning field.
In this blog, we will look at some of the key principles of Kubernetes and how this word or technology can turn out to be quite useful for carrying out machine learning workloads.
Understanding Microservice Applications
In today’s setting, the software community is mainly focusing on making software more flexible and correctly distributed, where individuals are contributing to developing large apps a series of smaller services so that these little components may be maintained and developed separately. All of these little services operate on the same network and communicate with one another via APIs, channels, or other similar technologies.
There are several advantages to designing a huge application in tiny sections. The primary advantage of designing microservices is that they are simple to build and manage, in contrast to huge applications, which require several methods and dependencies. Furthermore, developing and reproducing numerous tiny internal methods and scaling them parallelly makes a huge application more efficient. When cloud services are included, computing resources may be assigned and scaled more quickly.
One of the most notable advantages of these microservices is that they tend to be more robust than other methods due to separated internal services, and when set up properly, they are immune to failure.
When it comes to microservice architecture, we can state that they’re more suitable to a cloud environment where resource linking or allocation along with detaching or deallocation are simpler and more rapid. Overall, when a large app uses several microservices, these microservices demand various computing resources to execute, therefore this all works based on the need for much more granular scaling up and down. This makes the overall design more durable and superior to monolithic architecture, which requires us to grow the entire program.
Container technologies like Docker assist in the effective operation of this architecture. We may bundle the dependencies and prerequisites with the aid of docker-like technologies and run on any sort of hardware with fewer compatibility requirements. This makes it easier to manage the services.
Basic core concepts of Kubernetes
-
Kubernetes Cluster:
As previously stated, clusters are made up of a master node that is in charge of operating the major Kubernetes services and numerous worker nodes. These nodes must be accessible for processing inside the cluster. We are allowed to assign numerous worker nodes to a cluster as we require. The master node is in charge of ensuring that user-defined configuration pods are kept up to date at all times.
-
Kubernetes Pods:
They are the smallest deployable units in Kubernetes, and they are frequently containerized using Docker. Kubernetes may use the container orchestration capability to guarantee that pods use energy and resources as needed.
Kubernetes working for Machine Learning
Building a machine-learning model can sometimes seem simple or basic. But when you are incorporating it into your IT infrastructure, the complexity starts to grow. Because it frequently depends on multiple elements like libraries, artifacts, as well as parameter files. You must understand that the computing demands for different resources vary. For example, a TensorFlow-based model requires more computational resources as compared to a Scikit-Learn-based model.
We are now also aware that a microservice architecture is the most suitable architecture for running and managing apps or services with different requirements. This is the reason why many machine learning and artificial intelligence models can be operated effectively with Kubernetes & microservice architecture.
There are a lot of open-source Kubernetes extensions on the market for managing workloads related to machine learning, such as Kubeflow. But integrating and mastering them is not that straightforward.
When to use Kubernetes?
We already know about Kubernetes’ strengths and are also well aware of its capabilities. ML workloads or models can also fully leverage those functionalities. It can also be a huge help where dispersed, large-scale machine-learning operations are involved. Let’s look at a few cases where using Kubernetes for machine learning might be beneficial for you:
-
Scalability :
You can utilize Kubernetes when scaling machine learning operations requires intense/complex data management or data processing. This is possible because Kubernetes can effectively manage containerized machine learning applications’ deployment, scaling, and administration while also making sure that the resources are used to their fullest potential.
-
Portability :
Workloads may be easily moved between on-premises and cloud systems thanks to Kubernetes integration, which is one of the main benefits of the system. The same holds for machine learning workloads, which may be moved between on-site data centers and cloud service providers.
-
Resource Optimisation :
You may save your resource expenses and accelerate machine learning processes with Kubernetes. By automatically and flexibly scheduling and scaling machine learning operations depending on available resources, you may use this to optimize your resource utilization.
-
Resilience :
Similar to other big infrastructures, Kubernetes makes sure that workloads for machine learning automatically recover from errors and are distributed among healthy nodes.
-
Collaboration :
This Kubernetes feature is a huge help to the machine learning engineering team because it gives them a centralized platform to manage their workloads. This makes collaboration more effective. Moreover, tools for sharing and versioning machine learning datasets and models might be included.
The complexities of facilitating Kubernetes
Kubernetes creates a lot of challenges and difficulties when it comes to managing and deploying containerized programs, especially ML workloads. Although Kubernetes gives microservices more capability, it also makes it more complex to create and manage several components, including controllers, nodes, pods, and services. Furthermore, maintaining the many dependencies and versions of software components, in addition to guaranteeing high levels of efficiency, protection, and availability, may lead to problems.
Furthermore, managing distributed and large-scale machine learning workflows may provide additional challenges in terms of information management, versioning, and cooperation.
Conclusion
Kubernetes emerged as a powerful tool for machine learning workflows since it not just orchestrates and maintains the workflow but also assists in creating scalable and autonomous environments around these processes. Meanwhile, using Kubernetes properly has its own set of issues that necessitate efficient engineering as well as a significant amount of resources and time to work only with Kubernetes.
