  • Anticipates future DCOS capabilities to support fine-grained diagnostics by drilling down from tasks to processes and threads.
  • Predicts the ability to execute new image-like formats, including Docker and Rocket container specifications, through pluggable support.
  • Forecasts that automated scheduling will surpass manual expert management in optimizing utilization and meeting service level agreements (SLAs).
  • Expects standard security interfaces will enable applications to move across organizations without being rebuilt for specific authentication mechanisms.
  • Projects that the abstraction layer will decouple hardware innovation from instruction set dependencies, allowing seamless migration to ARM servers or new networking infrastructure.
  • Suggests that greenfield deployments can utilize Mesos to bypass the 30% virtualization overhead inherent in virtual machines.
  • Plans to expand the DCOS concept to include stateful services that historically required significant human intervention for management.
  • Intends to develop maintenance primitives that treat planned downtime, such as rack outages, as planned failures for automatic task rescheduling.
  • Envisions future operating system primitives that collaborate with applications to handle failures and resource needs intelligently, moving beyond simple algorithms like LRU.
  • Aims to create a rich environment where applications continuously execute on underlying infrastructure, calling back to request resources or report status.
  • Notes current adoption by major enterprises including Twitter, Airbnb, HubSpot, eBay, PayPal, and Netflix.
  • Believes the shift to this abstraction layer will ultimately prove more efficient than the current fragmented and insecure state of distributed systems.
  • Expects the data center to function as a single computer, allowing users to launch tasks via CLI or pluggable interfaces without managing physical arrangements.
  • Plans to integrate a repository or registry-like system similar to package managers for the installation and execution of services.
  • Describes a system capable of monitoring, isolating, and relaunching failed tasks through explicit failure reporting.
  • Commits to continued support for containerization technologies, a practice established since 2009.
  • Identifies significant value for existing Infrastructure as a Service (IaaS) deployments in optimizing resource utilization through DCOS.
  • Predicts a trend over the next 10 years where thousands of applications self-optimize their resource consumption via the DCOS.
