State Management

Backup for GKE lets you protect, manage, and restore your containerized applications and data for stateful workloads running on Google Kubernetes Engine clusters.

A simple utility to manage state when testing

Manage how internal object state is copied.

This gem provides a common interface to many different types of virtual machine. The use case that it was written for is when you need an external system as part of your test procedures. Using a virtual machine with snapshot capabilities is extremely useful as you can reset the virtual machine to a known state at the start of every test.

Creates, terminates, and monitors Amazon EC2 instances. Creates more instance to meet increased demand, and terminates them when they are no longer needed. Any number of pools of instances may be managed. Provides periodic status reports. Three policies are provided: a fixed size pool policy, a job-oriented batch policy, and a resource-limited stateful policy. The user can define additional policies. To get started, see http://code.google.com/p/cloudmaster/wiki/Introduction

Lifecycle VM provides basic lifecycle management following the idea of only executing a single significant operation per program state.

Manage and share Terraform variables, environments, and states securely.

A Rails gem for managing the states of a model by defining wizard steps.

Rack::State is middleware that securely stores and manages object state. Applications use the Manager API to set, get, and delete state of any object that requires persistence in a stateless environment. Rack::State is similar to Rack::Session, but provides state management for multiple objects with independent control of the visibility, security, and storage of each object's state.

Redux like state management in OO Ruby

LinearWorkFlow is a basic state machine for managing state change through a single linear path

A creator and manager for game rules and state, separate from displaying and controlling the game. The idea is that a primarily-simulation game may be written using Ruby rules and a connection to the Demiurge process, while control and display are handled separately. This approach is primarily useful for 'simulation' games rather than fast-reflex 'twitch' games.

ShipEngine's easy-to-use REST API lets you manage all of your shipping needs without worrying about the complexities of different carrier APIs and protocols. We handle all the heavy lifting so you can focus on providing a first-class shipping experience for your customers at the best possible prices. Each of ShipEngine's features can be used by itself or in conjunction with each other to build powerful shipping functionality into your application or service. ## Getting Started If you're new to REST APIs then be sure to read our [introduction to REST](https://www.shipengine.com/docs/rest/) to understand the basics. Learn how to [authenticate yourself to ShipEngine](https://www.shipengine.com/docs/auth/), and then use our [sandbox environment](https://www.shipengine.com/docs/sandbox/) to kick the tires and get familiar with our API. If you run into any problems, then be sure to check the [error handling guide](https://www.shipengine.com/docs/errors/) for tips. Here are some step-by-step **tutorials** to get you started: - [Learn how to create your first shipping label](https://www.shipengine.com/docs/labels/create-a-label/) - [Calculate shipping costs and compare rates across carriers](https://www.shipengine.com/docs/rates/) - [Track packages on-demand or in real time](https://www.shipengine.com/docs/tracking/) - [Validate mailing addresses anywhere on Earth](https://www.shipengine.com/docs/addresses/validation/) ## Shipping Labels for Every Major Carrier ShipEngine makes it easy to [create shipping labels for any carrier](https://www.shipengine.com/docs/labels/create-a-label/) and [download them](https://www.shipengine.com/docs/labels/downloading/) in a [variety of file formats](https://www.shipengine.com/docs/labels/formats/).

Parse a reachability graph and process it using Mustache templates. Example State 2/2398339604900326310: / steps = <<"TenantManager", "Loader">> / db_data = {} / now = 1 / pc = [ Tail |-> "tail_wait", TenantManager |-> "tenant_manager" ] / db_tenants = {"t1"} / input_data = { [tenant |-> "t1", data |-> "d1"], [tenant |-> "t2", data |-> "d2"] } Transition -8297134421408988195 --> 2398339604900326310

A ruby class for managing states class-states

jQuery BBQ leverages the HTML5 hashchange event to allow simple, yet powerful bookmarkable #hash history. In addition, jQuery BBQ provides a full .deparam() method, along with both hash state management, and fragment / query string parse and merge utility methods.

Etat is a minimalistic gem to help you (me, for now) manage some states in your Rails app.

A StatefulController for Rails that uses a state machine to manage transitions between views.

Acmaker is a tool to manage AWS Certificate Manager (ACM). It defines the state of ACM using DSL, and updates ACM according to DSL.

State management for ActiveRecord, with states; transitions; and just the right amount of syntactic sugar.

ZD implements zero-downtime migrations as a managed series of state changes, with hooks for you to manage your code and data throughout the migration.

An abstraction over state managing actors

A set of [mustache] templates extending [tla-trace-filter] -tool to create a self extracting achieve for API traces generated, when model checking formal models created by [tla-Sbuilder] -tool. Also includes Ruby classes to extract test cases from archive extract. Use case: Formal models, built using [tla-sbuilder], and model checked using [TLA+tools]], can generate /API Traces/, which represent end-to-end scenarios executing across system services in the formal model. An API Trace is composed of steps, with each step giving 1) a (formal) system state before the API call, 2) the API call exercised together with (formal model) value bindings of request parameters, 3) API response returned, and 4) the (formal) system state after the API call. A API Trace can be mapped to /Unit Tests/ on implementation with each Unit Test corresponding a step in the API Trace. After executing each of the individual Unit Tests, the aggregate result can be interpreted as an execution of a "virtual" System Test - considerably easier than managing the execution a System Test as a single unit. The purpose of =tla-trace-arch= GEM is create a self extracting archive, which can be safely distributed to system service developers for extracting API Trace Steps to create unit tests for the service being developed by the developer.

Gunit-rails is a testing framework built on top of FactoryGirl. It is a middleware that manages seed data state during test suites and local development.

Reads the interface execution kinesis stream for NT2. Then it uses that execution info combined with information from VINE Services to determine if this is an error state. If it is, it sends a message to Einstein. It also clears Einstein alarms related to tracked errors. State is not tracked between runs, so if the job fails it won't manage previously created errors.

Polidef is a convience API for managing complex and potentially stateful conditionals through policy objects. Complex conditionals are fragile and can require a lot of state to exist in order to execute as expected. Polidef seeks to simplify implementation and testing so you spend less time wrangling conditional state and more time doing other things.
