VIRTUAL SERVER INFRASTRUCTURE
Loft Labs | January 10, 2022
Loft Labs, a venture-backed startup working on developer tooling and platform technology for Kubernetes, announced that the popular open source vcluster project now supports upstream Kubernetes.
Although engineers have already been able to deploy virtual clusters using vcluster on top of vanilla Kubernetes clusters, the virtual clusters themselves have always been using the opinionated K3s distribution internally rather than upstream Kubernetes. With this release, vcluster users will now be able to deploy Kubernetes-powered virtual clusters to improve and optimize utilization of computing resources without the need to use K3s within the virtualization layer.
We expanded vcluster support to vanilla Kubernetes in response to feedback from our user community. Many companies working with vcluster want to start leveraging the benefits of virtual clusters in production. Making these virtual clusters run with Kubernetes rather than K3s is a big step towards production-readiness for vcluster.”
Lukas Gentele, co-founder and CEO, Loft Labs
With the availability of upstream Kubernetes in vcluster, users can now also use any new Kubernetes feature immediately after its release and will not have to wait for K3s to ship their adapted Kubernetes version.
First launched in April 2021, vcluster is used to create lightweight Kubernetes clusters that run inside the namespaces of underlying Kubernetes clusters. Using virtual clusters solves the majority of multi-tenancy issues of Kubernetes because they offer:
Better isolation than simple namespace-based multi-tenancy;
Reduced cloud computing cost because virtual clusters are much more lightweight and resource-efficient than spinning up separate single-tenant clusters;
Logical separation and encapsulation of application workloads from the underlying cluster’s shared infrastructure workloads (such as shared ingress controller or network plug-ins).
At the same time, virtual cluster users can expect that their virtual cluster behaves just like any regular Kubernetes cluster because vcluster is a certified Kubernetes distribution, which means that it passes all conformance tests that CNCF requires. Virtual clusters are often used as development environments when engineers are building, testing and debugging cloud-native software, but they are also frequently used as ephemeral environments for executing continuous integration/continuous delivery (CI/CD) pipelines. Also, an increasing number of companies are starting to explore virtual clusters in production, where virtualizing Kubernetes can be a great way to: surpass the scalability limits of regular Kubernetes clusters; isolate heterogeneous workloads in shared clusters; and streamline and simplify cluster operations when working with large-scale multi-tenant clusters.
Loft Labs builds on top of vcluster and provides an enterprise-grade Kubernetes platform called Loft which is used by large organizations to create a self-service platform for their engineering teams. When an enterprise runs Loft, their engineers can provision virtual clusters on-demand whenever they need them, either using the Loft UI (user interface), the Loft CLI (command-line interface) or even using the Kubernetes command-line tool kubectl via the custom resources provided as part of Loft.
About Loft Labs
Loft Labs was founded in 2019 to create open-source developer tooling and virtual cluster technology for Kubernetes, with the goal to increase developer productivity and to help engineers gain secure but unimpeded access to cloud infrastructure.
Wavecrest Computing | October 15, 2020
Wavecrest, a global leader in employee Web-use management, monitoring, and analytics solutions, today announced the release of Cyfin’s newest feature, Virtual Private Network (VPN) Usage Reporting. VPN usage reporting supports today’s increased need to monitor remote employee Web-use while reducing the concern of extending enforcement of Acceptable Use Policies (AUP), managing productivity, and monitoring time online.
KIOXIA America | December 20, 2021
KIOXIA America, Inc. announced that its CM6 and CD6 Series of PCIe 4.0 NVMe SSDs have earned VMware vSAN 7.0 certification, enabling them to be shared across connected hosts in a VMware vSphere cluster. Users can pool KIOXIA SSDs together in a single, distributed, shared data-store and define the storage capabilities required (such as performance, capacity and availability) for each connected virtual machine within the VMware vSAN cluster. These capabilities not only further hyper-converged infrastructure (HCI) options in virtual environments, but also ensure that storage policies are administered and maintained within the CM6 and CD6 Series with vSAN compatibility.
This certification allows VMware vSAN support for both hybrid and all-flash configurations using a two-tier storage architecture, capacity tier and cache. All write operations are sent to the cache tier and are subsequently de-staged to the capacity tier over time. When a CM6 or CD6 Series SSD is deployed within a hybrid configuration, its cache tier is used as both a read and write cache, staging hot data to improve system performance. In an all-flash configuration, 100 percent of the cache tier is used for the write buffer. Given the benefits of tiered storage, CM6 and CD6 SSDs are capable of meeting the demanding requirements of both enterprise and data center customers.
“We are pleased to collaborate closely with KIOXIA and certify their datacenter and enterprise SSDs that address performance demands and latency sensitivities,” said Lee Caswell, vice president of product and technical marketing for VMware. “Flash performance is critical to our customers, and this certification demonstrates that they can rely on KIOXIA for proven compatibility and interoperability with VMware vSAN 7.0.”
The KIOXIA lineup of PCIe Gen4 (16GT/s x4) NVMe SSDs brings planned performance improvements of up to 2x over its PCIe 3.0 (8GT/s x4) predecessors and is 12x faster than 6Gb/s SATA drives1. KIOXIA was one of the first companies to demonstrate2 and ship3 enterprise and data center class PCIe 4.0 NVMe SSDs. KIOXIA CM6 enterprise and CD6 data center SSDs are SFF-TA-1001 conformant (also referred to as U.3) SSDs to support universal drive bay systems that can accept NVMe, SAS and SATA SSDs.
Earning VMware vSAN certification for our lineup of PCIe 4.0 NVMe SSDs provides customers with the confidence they need when deploying a vSAN solution. KIOXIA offers the broadest lineup of SSDs for the modern data center, and by collaborating closely with innovators, such as VMware, we can ensure that our technologies and products deliver significant and immediate value to server virtualization at the data center scale.”
