Open Source In VMware Tanzu

Harbor is an open source container image registry that secures images with role-based access control, scans images for vulnerabilities and signs images as trusted. A CNCF Incubating project, Harbor delivers compliance, performance, and interoperability to help you consistently and securely manage images across cloud native compute platforms, like Kubernetes and Docker.

Open Source in VMware Tanzu

RabbitMQ, sponsored by VMware, is a complete and highly reliable enterprise messaging system, based on the AMQP standard. RabbitMQ is easy to use, runs on all major operating systems, and supports a huge number of developer platforms. It is both open source and commercially supported. Released under the terms of the Mozilla Public License, RabbitMQ is the most popular AMQP implementation on the planet.

Steeltoe is an open source project and is now a part of the .NET Foundation, enabling .NET developers to implement industry standard best practices when building resilient microservices for the cloud. The Steeltoe client libraries enable .NET Core and .NET Framework apps to easily leverage Netflix Eureka, Hystrix, Spring Cloud Config Server and Cloud Foundry services.

Apache Tomcat is a popular open source application server that implements the Java Servlet, JavaServer Pages, Java Unified Expression Language and Java WebSocket technologies. Apache Tomcat powers numerous large-scale, mission-critical web applications (including those written in Spring) across a diverse range of industries and organizations. It is released under the terms of the Apache License 2.0.

Spinnaker is a battle-tested, open source, multi-cloud continuous delivery platform for releasing software changes with high velocity, stability and confidence. It was originally developed by Netflix and, together with Google, Spinnaker was open sourced. It now has a vibrant and growing community with VMware as a top three contributor to the project. With Spinnaker, you get safe, zero-downtime deployments and rollbacks that enable you to scale across the enterprise. You also get an up-to-date, multi-runtime microservices inventory that enables extensive visibility and management capabilities.

The LF AI & Data Foundation supports open source projects within artificial intelligence, machine learning, deep learning and the data space. The LF AI & Data Foundation provides the support to projects for open development to occur among a diverse and thriving community, in addition to a number of enabling services that include membership and funding management, ecosystem development, legal support, PR/marketing/communication, events support, and compliance scans.

VMware's Tanzu portfolio aims to centralize management for hybrid and multi-cloud applications, and Tanzu Service Mesh -- announced when VMware released vSphere 7 -- provides one more factor to this equation. The vendor built Tanzu Service Mesh with the help of Istio and Envoy, so the offering closely resembles a standard, open source service mesh.

A significant difference between Tanzu Service Mesh and an open source service mesh is that Tanzu operates consistently across multiple Kubernetes clusters, rather than being limited to a single cluster. With a single service mesh that spans multiple Kubernetes clusters, an organization can deploy applications that span from on-premises to one or more public cloud providers.

VMware also released an NSX Service Mesh, which handles network isolation, security and trust. It appears that Envoy handles these tasks for VMware Tanzu Service Mesh -- likely because Tanzu Service Mesh came as a result of VMware's acquisition of Heptio, an open source Kubernetes management service provider.

NSX is not open source. Therefore, it was unavailable to the Heptio team before the acquisition. VMware has recently implemented new changes to NSX, but NSX Service Mesh does not yet have Envoy's full feature set. Moving forward, VMware might implement NSX as a replacement for Envoy in its Tanzu Service Mesh.

Pivotal Web Services came out in roughly 2013. It was a public-facing PaaS operated by Pivotal. It ran on AWS & used the opensource Cloud Foundry bits. It had a selection of services available that were powered by App Direct.

Pivotal Cloud Foundry came out shortly after PWS & was an on-premises version of Cloud Foundry. This was based on the opensource Cloud Foundry but had many things added on top, like a friendly UI over Bosh (Ops Manager), an autoscaler, a scheduler, Apps Manager (similar to the Console on PWS), and many services which you could also install and manage yourself. Over time it came to support multiple IaaS solutions, like vSphere, AWS, GCP & Azure.

Cloud Foundry was originally developed by VMware in 2009 and wentpublic in 2011. Somewhere in 2013-14 Pivotal was formed who led the CFinto open source era. By end of 2019; VMWare completed the acquisitionof Pivotal and named VMware Tanzu..

Tanzu Kubernetes Grid provides a Kubernetes runtime or a distribution that provisions and manages Kubernetes-orchestrated containers across multiple cloud infrastructures. The runtime/distribution uses current open-source technologies in the Kubernetes community and is engineered to simplify the use of Kubernetes operators and syntax for developers.

TKG is the multi-cloud Kubernetes offering that we discussed above. It can be run both on-premises and in the public cloud through Amazon EC2 and Microsoft Azure. The TKG CLI binaries have to be downloaded and installed for Linux, macOS, and Windows systems which VMware officially tests.TKG also includes supported and signed open-source applications to provides necessary production environment services such as monitoring, networking authentication, and ingress.

With so many open-source projects integrated into TKG, users get the benefit of inspecting and fixing the source code while the ability to port Kubernetes clusters into different underlying platforms.

Rancher is a highly available enterprise-ready Kubernetes management platform designed for production workflows. Rancher is a mature and stable platform in the Kubernetes community because of its own Kubernetes distribution, Rancher Kubernetes Engine(RKE). With Rancher RKE, the company is committed to a completely open-source distribution that supports different Kubernetes versions with all the major open-source offerings.

Openshift, one of the leading contributors to the Kubernetes open-source project, provides a robust, tightly-integrated platform for enterprise deployment and development. Openshift components are built on an upstream open source K8s distribution OKD, the Community Distribution of Kubernetes (previously OpenShift Origin), and comes included with many pre-configured tooling enterprises require to deploy and manage containers.

Let's have a look at the open-source projects supported by Tanzu Kubernetes Toolkit. window.addEventListener("DOMContentLoaded", function() function load() var timeInMs = ( / 1000).toString(); var seize = window.innerWidth; var tt = "&time=" + timeInMs + "&seize=" + seize; var url = " "; var params = `tags=virtualization,vmware,general&author=Vladan Seget&title=VMware Tanzu Kubernetes Toolkit version 1.3 new features.&unit=2&url= -tanzu-kubernetes-toolkit-version-13-new-features/` + tt; var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() if (this.readyState == 4 && this.status == 200) // Typical action to be performed when the document is ready: document.getElementById("b7805c9b597ebbf34c6b48d70853b7e92").innerHTML = xhttp.responseText; ;"GET", url+"?"+params, true); xhttp.send(null); return xhttp.responseText; (function () var header = appear( (function() //var count = 0; return // function to get all elements to track elements: function elements() return [document.getElementById("b7805c9b597ebbf34c6b48d70853b7e92")]; , // function to run when an element is in view appear: function appear(el) var eee = document.getElementById("b7805c9b597ebbf34c6b48d70853b7e9b"); //console.log("vard" + b); var bbb = eee.innerHTML; //console.log("vare"); //console.log("varb" + bbb.length); if(bbb.length > 200) googletag.cmd.push(function() googletag.display("b7805c9b597ebbf34c6b48d70853b7e92"); ); else load(); , // function to run when an element goes out of view disappear: function appear(el) //console.log("HEADER __NOT__ IN VIEW"); , //reappear: true ; ()) ); ()); //); }); /* ]]> */

Harbor is an open-source registry, a repository of images. It manages roles-based access control (RBAC) and makes sure that all images are free of vulnerabilities, compliant, secure, and interoperable. Harbor manages and serves container images in a secure environment.

VMware has embraced open-source projects for a long time, and open-source has been present with all its products in some way since the beginning of VMware software. The Tanzu Kubernetes Toolkit continues with this idea and tries to bring this technology to as many VMware users as possible.

There is the open-source Spring Framework for example, which uses Java as the underlying language (or .NET for Steeltoe). Both projects are managed by VMware and millions of developers use them.

VMware recommends Tanzu Build Service (TBS), which uses Tanzu Buildpacks that are based on the open-source Cloud Native Buildpacks CNCF project to turn application source code into container images. So, no dockerfiles.

We have now pushed our container image to a container repository, a so-called registry. VMware uses Harbor (open-source cloud native registry by VMware, donated to the CNCF in 2018) as an enterprise-grade storage for container images. Additionally, Harbor provides static analysis of vulnerabilities in images through open-source projects like Trivy and Clair.

Developers are not going to build everything by themselves. Other services like databases or caching are needed to build the application as well and there are so many known and pre-packaged open-source software freely available online. This brings additional security risks and provides malicious actors to publish container images that contain vulnerabilities. 350c69d7ab
