A deployment system enables a developer to generate a deployment plan according to a logical, multi-tier application blueprint defined by application architects. The deployment plan includes tasks to be executed for deploying application components on virtual computing resource provided in a cloud infrastructure. The deployment plan includes time dependencies that determine an execution order of the tasks according to dependencies between application components specified in the application blueprint. The deployment plan enables system administrators to view the application blueprint as an ordered workflow view that facilitates collaboration between system administrators and application architects.

System to generate a deployment plan for a cloud infrastructure according to logical, multi-tier application blueprint

A deployment system enables a developer to define a logical, multi-tier application blueprint that can be used to create and manage (e.g., redeploy, upgrade, backup, patch) multiple applications in a cloud infrastructure. In the application blueprint, the developer models an overall application architecture, or topology, that includes individual and clustered nodes (e.g., VMs), logical templates, cloud providers, deployment environments, software services, application-specific code, properties, and dependencies between top-tier and second-tier components. The application can be deployed according to the application blueprint, which means any needed VMs are provisioned from the cloud infrastructure, and application components and software services are installed.

A deployment system orchestrates execution of deployment plan in coordination with nodes participating in deployment of a multi-tier application in a cloud infrastructure. The deployment system distributes local deployment plans to each node and maintains a centralized state of deployment time dependencies between tasks in different local deployment plans. Prior to execution of each task, deployment agents executing on each node communicates with the centralized deployment system to check whether any deployment time dependencies need to be resolved. Additionally, the deployment system utilizes a node task timer that triggers a heartbeat mechanism for monitoring failure of deployment agents.

A user may create a blueprint that specifies an application's architecture, including virtual machines (VM) nodes, software services and application components within the VM nodes. To do so, the user manipulates a graphical user interface (GUI) rendered by a graph layout manager and a Scalable Vector Graphics (SVG) layout engine. The SVG layout engine parses declarative layout configurations and translates the declarative layout into SVG elements that visually represent the blueprint. Additional information may be rendered in independent layers overlaid on the GUI which a user may selectively activate or de-activate to show or hide, respectively, the additional information. The layers may be generated using extension points exposed via the declarative layout.

A user may create a blueprint that specifies an application's architecture, including virtual machines (VM) nodes, software services and application components within the VM nodes. To do so, the user manipulates a graphical user interface (GUI) rendered by a Scalable Vector Graphics (SVG) layout engine. The SVG layout engine parses declarative layout configurations and translates the declarative layout into SVG elements that visually represent the blueprint. The SVG layout engine dynamically calculates absolute positions and sizes of child elements based on the declarative layout.

The SVG layout engine parses declarative layout configurations and translates the declarative layout into SVG elements that visually represent the blueprint. The graph layout manager renders topology connections representing deployment dependencies in the GUI using a street-block-and-roads design pattern.

A deployment system enables a developer to customize a deployment plan generated according to a logical, multi-tier application blueprint for deploying multiple applications in a cloud infrastructure. Using the deployment system, the developer inserts a custom script or task in a sequence of tasks to be performed to deploy an application component in different phases (e.g., installation, configuration, start-up) on a virtual machine. The deployment system anchors the custom script to the different phases of the application component's deployment such that the customizations to the deployment plan are maintained through changes to the underlying application blueprint.

Embodiments in the present disclosure include systems and methods related to a high-availability architecture for a cloud-based concurrent-access collaboration platform. The disclosed technology relates to an active data center which includes multiple document server instances that handle user requests for concurrently accessing documents. Multiple document server instances are implemented on a single physical server. This architecture uses an instance assignment manager to assign documents to the document server instances, a primary repository to store backup snapshots of the documents, and a datastore to store all changes made to the documents. The disclosed technology also involves a backup data center that can be swapped with the active data center automatically.

A graphical user interface (GUI) engine receives an input event associated with a drag-and-drop action, determines a Scalable Vector Graphics (SVG) element that relates to the input event, and causes an anchor element to be attached to the SVG element, such as be wrapping the SVG element with the anchor element. Attaching an anchor element to an SVG element and defining the anchor element as 'draggable' enables web browsers to perform drag-and-drop actions with SVG elements in a uniform and predictable manner. In one example use case, an SVG element may be wrapped with an anchor element when the SVG element is selected and dragged by a user, enabling an accurate representation of the SVG element to be displayed while the user is performing the drag-and-drop action.
