Introduction to Constellation architecture 

Pega Constellation is a true center-out way of creating software

UI architecture 

Constellation UI architecture shifts the way of how you deliver an experience to your users.

With the new client-side engine, orchestration of views is done in the browser itself.

the Infinity server no longer has to send big sets of data to the user's device – instead, it can limit the payload to small, data-driven packets. 

Constellation metrics show as much as a 7x smaller network payload and 3x faster interactions

Required - well defined granular API (necessary to enable the frontend engine to communicate flawlessly with backend services)

Front end developers - extend by introducing custom components and own corporate design systems. Even enables web developers to just use the Pega API alone, and add any web-standard frontend (React, Angular, etc.)

web-standard frontend - HTML, CSS, and JavaScript are front-end (or client-side) languages, which means they are run by the browser to produce a website front-end

New UX and low-code authoring experience

a data-driven and API-driven approach, and with client-side orchestration -  authoring approach allows for decoupling of the presentation layer and the business logic

By using App Studio, experienced System Architects to work hand-in-hand with Citizen Developers and Business Stakeholders to create business processes, without the need to customize the presentation layer.

 The benefits :

• End-users receive consistent experience across different processes and applications
• Case Type design is focused on business logic
• The application are configured (not customized), allowing for upgrades, easier adoption of new features, and an as-a-service approach. 

the web developers and System Architects can create custom components that deliver project-specific requirements

the delivery process is efficient and not bogged down around the presentation layer

True Center-out architecture

The Center-out concept puts the business value and customer journeys forward

Pega Platform enables clients to start with business needs and processes from the very beginning.

For example, when you want to add a mobile app as an alternative to a web portal, or when you need to expand to a new country, add country-specific requirements to Cases, and create localized language versions. 

With Pega Constellation, a true Center-out approach is made possible - create business-specific user journeys (userstory) that can be expanded more quickly in the future

Constellation UX – benefits (Speed , Power , Value)

businesses will derive more value from their investment - businesses will derive more value from their investment 

app builders and citizen developers will avoid designing and developing elements such as button colors, section rules, and screen layouts

IT departments will experience significantly improved performance and easier upgrades
