Deploying Services

There are several types of Services:

• Stateful PU This is the unit of packaging and deployment in the GigaSpaces Data Grid, and is essentially the main GigaSpaces service. The Processing Unit (PU) itself is typically deployed onto the Service Grid. When a Processing Unit is deployed, a Processing Unit instance is the actual runtime entity./Service - This is space containing data.

• Stateless PU/Service - These are built-in services such as mirror wan-GW, data-GW and custom services

• Client Services - These are applications which interact with spaces

• It is also possible to develop new services based on Blueprints.

Low-Code Micro-Services

Through GigaSpaces SpaceDeck GigaSpaces intuitive, streamlined user interface to set up, manage and control their environment. Using SpaceDeck, users can define the tools to bring legacy System of Record (SoR) databases into the in-memory data grid that is the core of the GigaSpaces system., easy low-code data access micro-services can be created. For more information, refer to SpaceDeck – Services

Components

Name	Function
Service Creator	RESTful REpresentational State Transfer. Application Programming Interface An API, or application programming interface, is a set of rules that define how applications or devices can connect to and communicate with each other. A REST API is an API that conforms to the design principles of the REST, or representational state transfer architectural style. endpoint for deploying, underploying a Query Service
Service Operator	Captures the knowledge of deploying and undeploying a Query Service
Query Service	Deployment: A stateless application running on a pod. The application will be deployed with x amount of replicas regardless of usage. Service: Exposes a single outward-facing endpoint to this application on the cluster (internal network) Ingress: Makes the HTTP (or HTTPS) network service available using protocol aware URIs, for example and external network

Service Creator

Services creation is managed by a Service Creator which, functioning as a RESTful application, manages the entire service deployment cycle.

The service exposes the REST endpoints, and is deployed in the environment via the Kubernetes An open-source container orchestration system for automating software deployment, scaling, and management. orchestration This is the automated configuration, management, and coordination of computer systems, applications, and services. Orchestration strings together multiple tasks in order to execute and easily manage a larger workflow or process. These processes can consist of multiple complex tasks that are automated and can involve multiple systems. Kubernetes, used by GigaSpaces, is a popular open source platform for container orchestration..

Low code development of data micro-services provide our clients with the ability to deploy and execute data services efficiently.

This assumes that the micro-service runs a query on the Space Where GigaSpaces data is stored. It is the logical cache that holds data objects in memory and might also hold them in layered in tiering. Data is hosted from multiple SoRs, consolidated as a unified data model. data. It enables the user to define endpoints that, per request, will run the predefined query using the supplied required parameters to get the results.

Any new service creation request generates a new resource of the kind QueryService by submitting a request to the ServiceCreator service .

ServiceCreator service exposes the following APIs:

• Deploy Query Service given Spec.

• Get service spec-parameters given its ID.

• Get list of available services of this kind (queryService).

• Delete service.

• Download logs of the service (using path /{serviceId}/logs
