This hybrid cloud platform helps developers manage and launch their services providing detailed visibility about resource usage and for infrastructure owners, to offer their infrastructure or platform as a true multi-tenant offering. Previously he worked as a Distinguished Engineer at Motorola, leading efforts to build their Notification Infrastructure, their Software Upgrade services and a Prospective Search based Content Delivery Service.

    Talk: Multi tenant infrastructure for fine-grained services at Twitter scale. Things that matter, from Sec

    Twitter is powered by a collection of diverse, multi-tenant infrastructure and platform services. We run Mesos/Aurora for general compute, Manhattan for storage, Hadoop for batch compute, Heron for stream compute and many more. These are run in a polyglot environment (internal DCs and public clouds).

    As a company scales from few developers to tens of teams, it is crucial to manage the lifecycle of a service and the multi-tenant infrastructures themselves. Things we will learn about are

    For application developers:

    • Managing service identities and credentials
    • Managing lifecycle of services, from launch to deprecation
    • Visibility into resource consumption by deployed services

    For managers:

    • Organizational accountability and visibility
    • Managing cost and resource efficiency
    • Authorizing and approving resource usages

    For operators:

    • Defining and and metering resource usage
    • Monitoring, optimizing and allocating resources and managing capacity
    • Enforcing access restrictions

    For platform owners

    • Managing the consumers to see who is using what part of infrastructure resources
    • Planning capacity expansion

    For financial planners:

    • TCO and unit price management
    • Quarterly budget and financial management
