6WINDGate
6WIND
In the 6WINDGate software architecture, the control plane and data plane are separate. Within the data plane, the 6WINDGate fast path runs isolated from the Linux operating system on a dedicated set of processor cores. The fast path protocols process the majority of network packets without incurring any of the Linux overheads that degrade overall performance. The fast path implements a run-to-completion model whereby all cores run the same software and can be allocated as required according to the necessary level of packet processing or Linux application performance. Only those rare packets that require complex processing are forwarded to Linux, which performs the necessary management, signaling and control functions. Packet processing information that is configured or learned (through control plane protocols) in Linux is automatically and continuously synchronized with the fast path so that the presence of the fast path is completely transparent to Linux and its applications. -

InvoicePlane
InvoicePlane Project
InvoicePlane is a free and open source invoicing application. The project is the official successor and owner of the codebase of FusionInvoice version 1.x, which was written by Jesse Terry. FusionInvoice was an open source software before but was transformed into a commercial product with the release of version 2.x. The main idea behind the InvoicePlane software is the creation of an application you host on your own server and use it for basic invoicing and client management. The target groups are freelancers, self-employed workers and small to medium sized companies which need a reliable and easy to use invoicing system but who can't afford an expensive software. InvoicePlane is translated into many languages by community members and more languages are coming soon. -

Control Plane
Control Plane
Control Plane is a modern, multicloud-native app platform (PaaS) built on Kubernetes that enables you to build, deploy, and run microservices apps faster and easier, with ultra high availability and ultra low latency. Unlike other app platforms, Control Plane is: Multicloud and Multi-Region: Your workloads run agnostically across the combined computing power and geographic regions of AWS, GCP, Azure and Private Clouds. You choose which regions of which clouds run your app and as long as one region of one cloud is up, so is your endpoint. Flexible: Microservices have as-if-native access to ANY service on ANY cloud (BigQuery on GCP, AD on Azure, SQS on AWS) without embedding credentials. Fast: Running on the best of the cloud-native ops stack for secrets management, metrics, logging, software-defined VPN, geo-intelligent DNS and more - integrated, pre-configured, and easy to use. Efficient: Cloud consumption elastically optimized to run with the exact resources required.
