Abstract: A cloud-computing service (e.g., a “Puffin Service”) is described. The service may maintain service and skill catalogs corresponding to various services to be deployed to a region (e.g., during a region build). The service may host numerous user interfaces with which various service and skill metadata may be provided. In some embodiments, such data may include one or more dependencies between skills. The data managed by the cloud-computing service may be utilized to build a dependency graph. Navigation of the dependency graph may be performed via one or more user interfaces hosted by the cloud-computing service. An orchestration service (e.g., a Multi-Flock Orchestrator) may manage bootstrapping efforts for any suitable number of services during a region build based at least in part on dependencies between skills.

Abstract: A cloud infrastructure orchestration service (CIOS) may track build progress made by any suitable number of regional orchestrators. The cloud infrastructure orchestration system may include any suitable number of regional orchestrators, each regional orchestrator executing in an isolated hosting environment (e.g., a service cell isolated from other service cells). An orchestrator control plane may be configured to generate a build plan for bootstrapping a plurality of services within a data center, the build plan may be generated based at least in part on a service build definition of a plurality of service build definitions, the service build definition specifying a deterministic process for bootstrapping a service of the plurality of services. The orchestrator control plane may instruct a regional orchestrator to perform bootstrapping operations according to the build plan and may track the progress of the bootstrapping operations on an ongoing basis.

Abstract: A cloud infrastructure orchestration service (CIOS) may track build progress made by any suitable number of regional orchestrators. An orchestrator control plane may be configured to generate a region build plan for bootstrapping a plurality of services within a data center. The orchestrator control plane may instruct a region orchestrator to execute a build according to the build plan. The region orchestrator may be configured to update an execution state corresponding to the execution of the region build plan as it executes steps of the ordered steps of the region build plan. At any suitable time (e.g., when executing one of the steps fails), intervention data may be received with which a new region build plan may be generated. The new region build plan may be used for subsequent execution of the region build. This may enable run-time corrections to be made.

Abstract: A cloud infrastructure orchestration service may maintain a service plan and manifest (SPAM) corresponding to a service to be bootstrapped (e.g., provisioned and deployed) to a cloud computing environment (e.g., to a data center). The service plan may specify a deterministic order of releases for performing a process to fully bootstrap the service using one or more build milestones and one or more execution units, each execution unit specifying ordered steps for transitioning between build milestones Each step may reference one or more execution target checkpoint transitions, which in turn reference an alias of a configuration file that defines a release. A manifest may be used to identify the configuration files and artifacts to be used by the releases and to validate the service plan. A SPAM may be used to reduce/eliminate nondeterministic behavior of previous orchestration systems and to provide visualizations of the bootstrapping process at different granularities.

Abstract: A cloud infrastructure orchestration service (CIOS) may be used to create a service plan and manifest (SPAM) that defines a deterministic order of releases for bootstrapping a service (e.g., provisioning and deploying resources of the service) to a cloud computing environment (e.g., to a data center). A corresponding manifest may be used to identify the configuration files and artifacts to be. The manifest may be used to validate the service plan. The CIOS may be configured to validate the SPAM. If compatible, the SPAM may be added to a SPAM set. A SPAM set (a collection of SPAMs corresponding to respective services) may be used to derive a version set (identifying configuration file and artifact versions) with which a directed acyclic graph may be generated. CIOS may bootstrap various services within the data center based at least in part on traversing the directed acyclic graph.

Abstract: Disclosed is a method for initiating startup of a rocket engine configured to run on a liquid fuel and liquid hydrogen peroxide, including the steps of: initially decomposing the liquid hydrogen peroxide by passing the liquid hydrogen peroxide through a catalyst bed; passing decomposition products from the catalyst bed to a reaction chamber of the rocket engine and mixing the decomposition products with the liquid fuel to initiate detonation. Once detonation is initiated, the liquid H2O2 and liquid fuel are passed directly to a reaction chamber of the rocket, bypassing the catalyst bed. A rocket system includes a rocket engine having an initial ignition circuit having a catalyst bed sized to support decomposition of liquid H2O2 for initial reaction with the liquid fuel. The rocket engine, upon initial ignition, is configured to run on liquid fuel and liquid H2O2 without first passing the liquid H2O2 through the catalyst bed.
