Before we start the Qlik Sense architecture components intimately, we must first understand two other components that are connected to the architectural components. These two parts are Qlik Sense Hub and Qlik Sense Management Console. they’re the Qlik Sense Clients which communicate and also interact with the sites.

Qlik Sense Clients

Qlik Sense Hub is that the platform where the user performs operations on the info and creates applications with required visualizations. it’s the place where users connect with the software and style dashboards for his or her business analysis. It provides easy drag-and-drop functionality, associative data model, range of visualization etc. The viewing of ultimate dashboards is flexible because the screen and its contents are automatically adjusted consistent with the screen size of the device like a laptop, desktop, tablet, mobile. The hub is developed by utilizing HTML5, CSS3, JavaScript etc.
Qlik Sense Management Console lets the administrator centrally manage all the operations happening in Qlik Sense. The services managed by the Qlik Sense management Console are:
• Data connectivity
• Application management
• Task management
• Security administration
• Data monitoring
• Auditing

Qlik Sense Nodes

The nodes are physical or logical computers that deploy separate or a mixture of services. This assigns certain roles to a node. There are often primarily three sorts of roles of a node supported the services it provides.
• User or consumer node that delivers apps to the top users.
• Scheduler node which manages all the service and app reloads.
• Proxy node that handles authentication processes, load balancing, and session handling.
Thus, typically there are two sorts of nodes, central nodes and rim nodes. Each node is capable of taking over multiple roles, deploying a mixture of Qlik Sense services and operate independently. you’ll use a node for either production, development or both at an equivalent time.

Qlik Sense Sites

A Qlik Sense site consists of a node system. It can have one node or multiple nodes systems, also referred to as servers. Every node system features a single repository, database, and license. A single-node deployment consists only of the central node which possesses all the specified services deployed thereon . It works in sync with the info repository and file sharing systems.

Whereas, a multi-node site may be a distributed system having services distributed across many nodes. The central node manages all the peripheral nodes. All the nodes share an equivalent repository, database and license key. A multi-node system also provides better scalability, resilience, reliability, governance, capacity and adaptability to suit customer requirements.

Qlik Sense Storage

There are two storage components that employment with other architectural components. One is that the repository database, and another may be a file share system. A repository database is additionally referred to as a Postgre database that keeps metadata. Moreover, this data is named entity data and isn’t very large in size.
A file share system stores the Qlik Sense application data like dimensions, measures, objects, and visualizations as binary files and such data files are made available to all or any the nodes or servers during a site. Thus, Qlik Sense apps stores as QVF files.

Qlik Sense Architecture Services

The services that are within the architecture are given below:

i. Qlik Sense Proxy (QSP)

This is the entry point for users and administrators through sources like hub and management console. The QSP serves many purposes like:
• Session management
• License provisioning
• Handling load balancing
• Linking with user identity providers like Active Directory, SAML etc.

ii. Qlik Sense Engine (QIX)

This is the most interactive engine that promotes the main functionalities of Qlik Sense. The functions of QIX are,
• Data indexing and calculations for In-memory data
• Smart searching
• Interactive and self-service interactions
• Corresponds with Scheduler, Repository and Applications

iii. Qlik Sense Schedule (QSS)

The Qlik Sense Schedule role is to schedule and coordinate the info loads and application reloading.

iv. Qlik Sense Repository (QSR)

This is the place for all data and knowledge associated with the configuration and management of other Qlik Sense services. the most areas of labor of QSR are:
• Managing user definitions
• Security

v. Qlik Sense Applications (.QVF)

This is the last layer for users to use the info for creating visualizations and sheets in Qlik Sense. A Qlik Sense application consists of sheets and an entire set of these makes a Qlik Sense application. Also, QVF file has compressed data that pertains to the info loaded into the Qlik Sense’s in-memory and a final presentation layer.
