Mesosphere finalized $10.5M in Series A funding on Monday in a round led by Andreessen Horowitz. The San Francisco-based startup intends to commercialize Apache Mesos technology to help enterprises experience the datacenter-related economies of scale enjoyed by handful of internet giants such as Twitter, Netflix and eBay. Apache Mesos enables organizations to manage datacenters as if they are a single machine as opposed to a veritable ecosystem of computing, storage, networking and application components. Mesos technology aggregates datacenter resources and automates the processes required for day to day management of IT operations. Apache Mesos uses containerizer technology to “provide an environment for each executor and its tasks to run in” for purposes of “resource isolation” in contradistinction to containerization, which represents a “general concept that can encompass such things as packaging.” By encapsulating a datacenter within the rubric of one entity using Mesos technology, enterprises can enjoy improvements in resource utilization, fault tolerance, scalability, performance and simplicity of management. Brad Silverberg, co-founder of Fuel Capital, which also participated in the Series A funding raise, described the concept of managing a datacenter as one machine as “the holy grail of cloud computing” that had yet to be delivered successfully by any technology with the exception of Apache Mesos. Organizations that currently use Mesos technology include AirBnB, HubSpot, eBay, Netflix, OpenTable, PayPal and Twitter. Today’s funding raise also featured the participation of Data Collective in addition to Andreessen Horowitz and Fuel Capital.
