Computing Services: Saas (Software As A Service), Paas (Platform As A Service), And Iaas
Cloud software is offered "as a service", meaning consumers pay monthly subscription fees for digital models that can scale with changing needs.
Subscription models also enable greater flexibility; consumers may add or reduce usage as necessary.
Opting to compare these three models by clicking their respective buttons allows you to gain more knowledge regarding Software as a Service (SaaS), Platform as a Service and Infrastructure as a Service - typically all three deployment models used together by cloud computing services today and often interwoven as one another.

Side By Side Extensibility
Add side-by-side extensibility with SAP Business Technology Platform (SAP BTP), which offers service key that help create business applications which take advantage of BTP services like data management and analytics, integrations with SAP applications as well as third party apps, as well as hundreds of pre-built SAP and third-party integrations.
Note that side-by-side extensibility can also be accomplished using other platforms than BTP, such as public APIs.
As SAP continues to add services for SAP Systems, SAP BTP will offer superior extensibility. It enables extensions that run alongside the core system using only approved APIs ensuring smooth upgrade processes can take place.

Capabilities S/4hana Cloud Abap Environment
The SAP S/4HANA Cloud ABAP Environment can be used by SAP development Services to increase application capabilities.
These are a few primary capabilities to serve as a reference.
- Create custom tables that include the fields that you want to expose using CDS views.
- To custom CDS displays, include a Behaviour Definition. Transactional CDS view behavior will be included in the behavior definition.
- (Create/Update/Delete Functionalities).
- CDS Views are exposed as a service that can be consumed by Fiori Applications.
- Create custom job templates for applications to support custom business processes. The template can include business logic.
- Schedule applications using a customized template
- Create a Connection for an HTTP Service Using the Handler Class. (To facilitate user dialog).
- Standard SAP CDS views can be used by custom development to access business data and carry out necessary processes.
- EML (Entity manipulation language) can be used for consuming behaviors of RAP business objects. EML can be used to implement actions that trigger a CREATE first and then an UPDATE.
- Enhancement options and improvements are constantly being made in the ABAP environment. Enhancement spots are released for BADIs to extend standard functionality.
SAP S/4HANA Cloud: Characteristics

SAP S/4HANA Cloud: Components
SAP S/4HANA refers to both SAPs HANA database and Business Suite 4 solutions as components of their solution portfolio.
SAP S/4HANA, the latest edition of SAPs business suite, represents an entirely new era.

SAP HANA
HANA is an in-memory column-oriented database used by SAP S/4HANA ERP that stores, receives, and queries data in real time.
HANA features an in-memory computing system allowing it to read data directly from disk instead of RAM storage for faster data access and query processing/querying; its columnar design stores all related columns together compared to row-oriented systems which store entire rows all at the same location allowing quicker access of any specific columns needed to answer a particular query quickly.
Core Data Services
Core Data Services provide an umbrella of domain-specific services and languages designed to create semantically rich data sets for consumption by multiple applications.
Their CDS layer serves as a universal data processing language used in multiple apps; SAP S/4HANA cloud users can make use of CDS views as input to analytics or user interface systems or even directly accessing this data themselves.
SAP Fiori Launchpad
The SAP Fiori Launchpad serves as a centralized point of entry into SAP S/4HANA across desktop and mobile devices, offering services like navigation, personalization and embedded support.
Each tile represents an application which may be launched by users; role-based launchpads show only apps applicable for that role and cover tasks ranging from transactional to analytical tasks.

Two-Tier ERP Deployment

Two-Tier ERP Deployment Overview
Organizations need a reliable and agile enterprise resource planning (ERP) system in place in order to respond rapidly and sustainably to changing market conditions while creating an equitable business environment that benefits stakeholders and users.
Two-tier ERP refers to when an organization uses multiple ERP solutions at different levels (from different vendors).
A two-tier model can take many forms. An example would be having Tier 1 serve as the global ERP backbone (e.g. finance), with Tier 2 tailored specifically to localized needs or smaller business units.
This setup enables organizations to standardize Tier 1, while still meeting budgetary and functional requirements with Tier 2.
SAP S/4HANA Cloud public edition provides organizations with an economical means of quickly and quickly deploying public cloud development services for subsidiaries while still meeting TCO goals.
Close integration between SAP S/4HANA or its private edition located at headquarters and subsidiary would guarantee increased visibility; but with adaptable implementation enabling quicker service deployment this approach allows more adaptable management for each subsidiary.
Other market drivers for adopting a two-tiered ERP could include:
- Onboarding new acquisitions quickly.
- Standardizing subsidiaries to a harmonized framework.
- Prepare for a divestiture.
- Adapting new processes or new business models.
- Centralizing services such as finance or procurement.
- Extending supply chain control to business partners.
- Joint Ventures: A Joint Venture is a great way to expand.
- Adapting to changing geopolitical conditions.
- Prepare for the change in data residency regulations.
How To Design An Effective Two Tier ERP Strategy
An effective ERP strategy for two-tiers involves more than simply integration scenarios; rather, this strategy must outline reporting requirements for every satellite or subsidiary and consider any interdependencies among business processes that may impact them.
At an enterprise-level, reporting strategies need to be established both intercompany transactions as well as enterprise-wide reports in advance.
Master data management should also be an early consideration and planned into integrated processes as it requires many new systems requiring end user training programs as well as potential changes due to interdependencies among organizational entities. Change enablement encompasses many facets.
