Developers and IT specialists alike now choose Kubernetes as their preferred container orchestration technology. Kubernetes has transformed how contemporary software is created and distributed by automating the deployment, scaling, and administration of containerized applications. But now that VMware Tanzu has been released, many are left to question if Tanzu is just another term for Kubernetes.
Tanzu is a collection of goods and services made to assist businesses in creating, running, and managing contemporary applications using Kubernetes. Numerous tools and services are included, such as Tanzu Kubernetes Grid (TKG), which offers a consistent, enterprise-grade Kubernetes environment across various cloud providers and data centers.
Although Tanzu is based on Kubernetes, it’s vital to realize that the two are not the same. Tanzu, on the other hand, is a set of resources and services made to facilitate the development, operation, and administration of Kubernetes-based applications. For enterprises trying to implement contemporary application development processes and maintain competitiveness in today’s fast-paced digital market, understanding the distinctions between these two technologies is crucial.
Read the blog for more information on the variations between Tanzu and Kubernetes.
What is Tanzu?
Tanzu is a set of tools and services created to assist businesses in creating, running, and managing cutting-edge applications using Kubernetes. It consists of a number of parts that combine to offer both developers and IT specialists a complete solution.
– Tanzu Kubernetes Grid (TKG): A consistent, enterprise-grade Kubernetes environment across several cloud service providers and data centers is offered by TKG. It makes current application development approaches more accessible to enterprises by streamlining the deployment and management of Kubernetes clusters.
– Tanzu Application Service (TAS): A platform for managing and delivering cloud-native apps is TAS. Regardless of the underlying infrastructure, it offers a uniform runtime environment for applications and has built-in scalability, routing, and load balancing features.
– Tanzu Mission Control (TMC): For Kubernetes clusters operating across several clouds and data centers, TMC offers a single administration panel. It gives businesses the ability to apply rules, keep track of performance, and automate work over their whole Kubernetes estate.
Key features and benefits of Tanzu:
– Simplified deployment and management: Cloud-native apps and Kubernetes clusters may be easily deployed and managed using Tanzu. This shortens the time and effort needed to get started when implementing contemporary application development approaches.
– Enterprise-grade reliability and scalability: Tanzu offers enterprise-grade dependability and scalability for cloud-native applications thanks to its integrated load balancing, scaling, and routing features. This guarantees that apps can manage enormous volumes of traffic and operate well under pressure.
– Centralized management and automation: Tanzu’s Tanzu Mission Control centralized management console offers a single point of control for managing Kubernetes clusters across various clouds and data centers. This lowers the risk of mistakes and downtime by enabling enterprises to apply regulations, monitor performance, and automate processes across their entire Kubernetes estate.
The deployment, scaling, and maintenance of containerized applications are all automated via the open-source container orchestration technology known as Kubernetes. The Cloud Native Computing Foundation (CNCF) currently maintains it after Google initially built it.
Components of Kubernetes
– Nodes: Containerized applications are executed on discrete servers or virtual machines called nodes.
– Pods: In Kubernetes, pods are the smallest deployable units. They are composed of a single container or several them, all of which share the same network and storage resources.
– Services: Services give a group of pods a consistent IP address and DNS name, facilitating access to Kubernetes-based containerized applications.
– Controllers: Controllers keep Kubernetes objects in the appropriate condition by monitoring the amount of active pods, their health, and availability.
Key features and benefits of Kubernetes:
– Scalability: By autonomously adding or deleting pods in response to demand, Kubernetes enables applications to grow horizontally. This guarantees that programs can withstand huge traffic volumes without experiencing outages or performance problems.
– Portability: Kubernetes makes it possible to install and execute applications on any infrastructure, including on-premises, cloud-based, and hybrid environments. This eliminates vendor lock-in and makes it simple to migrate apps between environments.
– Resilience: Kubernetes comes with built-in features for load balancing, self-healing, and rolling upgrades, ensuring that applications continue to run smoothly and stay available even when there are problems.
– Extensibility: Kubernetes is incredibly extensible and has a strong ecosystem of plugins and extensions that can be used to increase its capabilities and combine it with other tools and platforms.
Differences between Tanzu and Kubernetes
Although Tanzu and Kubernetes have certain similarities, they also differ significantly in a number of important ways. Organizations may select the best tool for their unique needs by being aware of these variances.
– Architecture and Deployment Models:
Kubernetes is an open-source container orchestration technology that may be installed on-premises or in the cloud. Its architecture and deployment models are described below. It offers a complete set of tools and functionality for setting up, growing, and controlling containerized applications.
In contrast, Tanzu is a collection of tools and services developed on top of Kubernetes. It offers new tools for building and maintaining cloud-native apps, as well as extra capabilities for managing Kubernetes clusters across various clouds and data centers.
– Support for Different Types of Workloads:
Kubernetes is a general-purpose container orchestration technology that can accommodate a number of workload types, from stateless microservices to stateful databases.
On the other hand, Tanzu is intended exclusively for the creation of cloud-native applications. It provides tools for creating, deploying, and maintaining Kubernetes-based applications as well as tools for connecting with other frequently used cloud-native development platforms.
Due to Kubernetes’ extensive and vibrant ecosystem of plugins and extensions, integrating it with other tools and technologies is simple. It is a popular option for developing cloud-native apps since it has been accepted by several of the industry’s top cloud providers, including AWS, Google Cloud Platform, and Microsoft Azure.
Tanzu contains a range of CI/CD tools, databases, and messaging services for interfacing with other technologies frequently used in cloud-native development. Additionally, a complete set of APIs and SDKs are provided for creating unique integrations.
– Models for pricing and licensing:
Free open-source software called Kubernetes is readily accessible. Although using a managed Kubernetes service offered by a cloud provider or third-party vendor may incur additional fees, many enterprises opt to do so.
The cost of VMware’s commercial solution Tanzu depends on the particular tools and services it offers. Tanzu licence is often offered per-core, plus support and maintenance fees.
