What does an operating system for today's datacenter look like? Why do we even need one, and how does it function? Mesosphere's Benjamin Hindman, the co-creator of Apache Mesos, joins Steven Sinofsky for an all-OS discussion.
Segments Timeline
Introducing the Data Center Operating System
In this segment, Steven Sinofsky introduces Benjamin Hindman from Mesosphere to discuss the concept of the Data Center Operating System (DCOs). They explore the complexities of modern applications that span multiple servers and the challenges of resource allocation, drawing parallels to early computing days when programmers manually managed resources.
"good afternoon everybody this is Steven Sinofsky here with the a16 Z podcast very excited today to have Benjamin Hyneman of mrs. fear here today and we're gonna talk about a new concept that the compa..."
The Waste Crisis in Data Centers
Benjamin Hindman highlights the inefficiencies in current data center operations, where 85% of resources go unused. He contrasts this with the past, where programmers had to optimize resource allocation, and discusses how the DCOs aims to address this waste by managing resources more effectively.
"real challenge of just allocating resources and figuring things out reminds me personally of the very early days of computing when when programmers were responsible for allocating the resources of a m..."
Components of the Data Center Operating System
Hindman explains the architecture of the Data Center Operating System, likening it to a microkernel. He discusses Apache Mesos as the core component and how it integrates with various data center services like Kafka and HDFS to manage infrastructure efficiently.
"and waste in a data center is is a big mess eighty-five percent of the resources go unused and and I think to me that's where where the data center operating system really comes in and so I think that..."
Task Management in DCOs
In this segment, Hindman elaborates on task management within the Data Center Operating System. He differentiates between tasks and processes, explaining how tasks are the fundamental units that consume resources and how they are scheduled and managed within the system.
"system so you can really think about the base level is the kernel which is which is may so it's just like a kernel in an operating system and then things like storage something like HDFS which leverag..."
How DCOs Operate in a Data Center
Hindman describes the operational mechanics of the Data Center Operating System, detailing how tasks are launched and managed through services like Marathon. He explains the communication between agents on individual machines and the Mesos master, which orchestrates resource allocation.

Integrating Containers: Flexibility in Deployment
Hindman discusses the role of containerization technologies in the Mesosphere DCOs, explaining how users can deploy existing Docker images and other container formats. He emphasizes the flexibility and efficiency of running containers in a distributed manner, enhancing the overall functionality of the datacenter operating system.
"system is because I think in the day somebody should be able to build an application against the primitives like security primitives that could be provided by it by a data center operating system and ..."
Revolutionizing Resource Management
The conversation shifts to how the DC/OS changes the abstraction of resource management in datacenters. Hindman draws parallels to virtual memory, explaining how the new abstractions can lead to better resource utilization and scheduling, ultimately improving efficiency and performance.
"stuff evolves as other companies introduce new image like formats to describe the bits you need to run your containers again this is just going to be something that we can plug in to our data center o..."
Challenging Traditional Views on Virtual Machines
Hindman addresses skepticism regarding the effectiveness of a datacenter operating system compared to traditional virtual machine management. He argues that the DC/OS can outperform manual resource organization by providing sophisticated scheduling and resource management capabilities.
"covers today on set your laptop and you just gave us you know the binary that we need to run whether it's a container image or whether it's or whether it's a you know some some real binary well so if ..."
The Importance of Abstraction in Datacenters
The discussion highlights the significance of abstraction layers in modern computing. Hindman emphasizes that transitioning to a new set of abstractions can lead to improved security and resource utilization, urging IT leaders to embrace these changes for better operational efficiency.
"swap tuning code so I knew exactly where in memory it was gonna be and so it seems crazy to think like that like cuz aren't a bunch of hardcore people just gonna say no the problem is if I have a whol..."

Maximizing Resources with Mesos
Hindman explains how a data center operating system does not compete with infrastructure as a service but enhances it. He highlights the importance of effectively utilizing both virtual and physical resources, especially for organizations already using IaaS. The segment underscores the cost savings and efficiency gains from adopting Mesos in cloud environments.
"it that they'll that should understand about moving to a missus kind of environment rather than take this intermediate step of doing a bunch more VM stuff or better managing review right right right y..."
Building from Scratch: Avoiding Virtualization Overhead
In this segment, Hindman discusses the advantages of starting fresh with a data center operating system instead of going through traditional virtualization. He points out that new applications can be designed to utilize resources more efficiently, avoiding the 30% overhead typically associated with virtualization, thus saving costs and improving performance.
"you have but for people that are starting from scratch I think you can really now start to take a very close look on whether or not you need to go through that first level of virtualization or not and..."
Platform as a Service vs. Data Center OS
Hindman contrasts platform as a service (PaaS) with data center operating systems, explaining that while PaaS abstracts away infrastructure, it doesn't address the complexities of distributed systems. He emphasizes the need for applications to interact with the underlying data center OS to manage resources effectively, especially during maintenance and scaling.
"gonna squeeze in and use the right amount of resource yes that's exactly right so but don't I want to go back one quick SEC to the platform as-a-service because to me they're like platform as a servic..."
