Deploying Stateful Containers in the Cloud?​ Nuvoloso was founded to make migrating and running applications across clouds frictionless, more secure, and affordable. Today, we are building software to solve the problem of managing persistent data in Kubernetes deployments—and have assembled a core community of Kubernetes leaders looking to help shape the solution and gain early access. The Problem We Solve Companies are moving their applications to the cloud to improve business agility. Kubernetes and containers have become the de facto enabling technology for this transformation. But Kubernetes does not address requirements for compliant data protection, availability, security, and performance. Managing persistent data in this environment is still a laborious task. As a result, cloud transformation stalls: agility goes down, costs go up, initiatives cut corners and data control can be lost What We Offer Nuvoloso software provides enterprise data services such as container storage, protection, availability, security and performance to Kubernetes applications in the cloud. The solution is built on a wholly new architecture and use model, optimized for modern cloud resources and service delivery. App owners can “order” capabilities to meet service level objectives (SLOs) based on desired outcomes, not technical implementation. Resource provisioning and management operations are automated ─ delivered in a consistent, auditable, end-to-end process based on application needs. Nuvoloso removes data management friction from dev/ops, enabling you to deploy, run, and evolve applications with maximum agility—and at the same time, provide better data control than what’s achievable on-prem.

Xcalar is pushing the limits of technology to help people discover deep meaningful insights from data. We have built a next-generation open and extensible analytics platform and a modern day DW for the complete analytics pipeline. This includes data preparation/quality, virtual data warehousing, large-scale interactive analytics, data science, and workload operationalization. Users interactively build dataflows using visual design, SQL, and structured programming, and execute them at petabyte scale. Xcalar's enterprise-grade software scales to hundreds of nodes and thousands of users for both cloud and on-premises deployments. It provides visibility, access, and auditability, with sophisticated data lineage through all stages of the data transformation process. Patented technologies deliver actionable insights with simplicity, speed, and scale. At Xcalar we strive to bring fundamental change to the world of big data analytics. We hire people with talent and drive--those who excel in their disciplines, and have an endless thirst and curiosity for more.

IO Turbine was acquired by Fusion-io. The IO Turbine software takes advantage of flash local to the server, delivering improved performance for virtualized workloads by holding data close to where it is used. This approach avoids the need for expensive performance-oriented networked storage systems and memory appliances that struggle to deliver performance from the far end of a network, instead allowing enterprises to use cost optimized shared storage systems. The marriage of ioMemory and IO Turbine software improves ROI by increasing the number of virtual machines per physical server. Moreover, this makes it feasible to virtualize data intensive applications that were previously difficult to migrate to virtualized environments while maintaining performance. Enterprises will be able to virtualize their entire suite of applications and finally realize the benefit of running a single unified virtualized environment. Please see the Fusion-io website for more information. Thank you for your interest.
