SAP & the Cloud and SAP System Administration & Management 2

Introduction of Cloud

Resiliency or the ability to “self-heal”. Elasticity or the ability to grow and shrink based on

workload demands. The perception of infinite scalability. Self-service or automatic provisioning capabilities. Consumption-based or “pay-as-you-go” (PAYG)

pricing models Shared infrastructure and other resources (often

enabled through the use of virtualization, although this is not required)

Benefit of Cloud

Using the cloud, IT organizations can more quickly provision IT resources based on rapidly evolving business demands.

IT organizations that use cloud-based resources need fewer of their own IT professionals.

The ability to change how business users get their work done is another great unexplored area of cloud computing. The cloud can provide a mobile workforce with access to quickly evolving IT services and solutions.

cloud-based systems open the door to round the-clock access, just-in-time updates, and real-time business insight.

Service Provider

This hosting entity is often referred to as a service provider.

There are various types of clouds Internal private clouds Hosted private clouds Public cloud Hybrid cloud 1. Internal cloud:->i. High level of control and security.ii. Innovative first step toward cloud computing.iii. Ability to comply with regulatory requirements.iv. Fewer integration or performance issues than its public

counterparts.19/04/2023

Internal Private Cloud

19/04/2023 SAP & the Cloud and SAP System Administration & Management


Hosted Private Cloud

As opposed to an internal private cloud in which company sign up with the hosting provider that specializes in providing the dedicated services to the customer but in this type of cloud they come out with some of its own resource specially for the customer.

In this the resources are not shared with the other company hence it is more secure then their public counterparts.

Private cloud will cost more then the public because there is less opportunity to reduce the provider’s overall costs.

Hosted Private Cloud (cont’d)

Public Cloud

Any cloud infrastructure, platforms, or software hosted outside the company and provided by another party is considered part of the public cloud.

cloud systems are simply not ready to handle the next wave of business-critical and mission-critical applications. Beyond service level issues, other risks or potential issues related to the public cloud include other risks or potential issues related to the public cloud-:

Little maturity and guidance and therefore few business-critical and mission critical references.

New administrative tools and operational processes might be necessary to marry public cloud systems with the company’s existing applications and platforms.

19/04/2023


Public Cloud (cont’d)

Questionable or non-existent support for international, national, or local regulations and other matters of governance related to ITAR, FDA, PCI, HIPAA, and so on.

Lack of legacy application support in most cases (including the ability to natively support SAP application servers in all but the simplest and least beneficial cloud service models, for example).

Public Cloud (cont’d)

19/04/2023


Hybrid Cloud

we define a hybrid cloud service as any extended or “tiered” platform comprised of interconnected public and private or on-premises and cloud resources.

The ability to enable best-of-breed innovation, both from a platform and application perspective (Hybrids enable you to weave together best-in-class hosted customer relationship management [CRM] systems with your own back-end proprietary systems, for example.).

The potential to significantly reduce risk compared to a pure public cloud scenario.

The ability to craft a custom cost model that better balances capital expenses with operational expenses, enables partial pay-as-you-go benefits, and so on.

Client Server Architecture

To minimize the risk, cost and effort for handling mission critical application and business critical application.

SAP’s Web Application Server: SAP didn’t make the switch between client/server and more contemporary computing models in one great leap. Web-based computing platforms helped propel the SAP application platform’s evolution.

Service-Oriented Architectures: Service-oriented architecture (SOA) is nothing more than an approach to designing a more innovative computing platform that takes advantage of reusable services to build powerful business processes.

This approach takes a bit more time up front but saves a huge amount of time in the long run, particularly with regard to ongoing maintenance when changes need to be made.

Software as a service (SaaS)

This creates the perfect user centric experience. Examples are CRM, HCM and procurement processes. This Enterprise centric approach of On Premise installations

allows visualizing and executing unlimited complexity and individuality. It helped and will help enterprise organization to execute processes in best manner and with highest efficiency for the corporate organization.

Enterprise SaaS solutions are highly adopted if a first class user experience is combined with backend to ensure enterprise integrity of data and processes.

SaaS require more discipline in the standardization of processes.

19/04/2023


Cloud Consumer Perspective

Cloud computing is often divided into three broad service models or types based on the different consumers of each model and who provides or manages the assets. The three models are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS)

19/04/2023


Platform as a Service (PaaS)

PaaS is a set of tools and services designed to make enhancing and deploying SaaS applications quick and efficient. The approach allows extending applications and creating a better fit to specific and individual business requirements.

PaaS allows quick creation and launch of differentiating services. It also allows the Software and Service Ecosystem to build niche partner solutions and process large amounts of data quickly.

PaaS is designed to cover the entire software development life cycle, flexibly and on a large-scale.

SAP and Cloud

Pillar 1 Scalability- SAP has always been amazingly scalable given

its tiered architecture (where the data base, application server, and Internet services may be broken out into their own horizontally scalable service delivery platforms).

Pillar2 Cloud service- SAP spoke of providing its own cloud

services, citing examples such as talent management and sales force automation. This kind of approach makes sense and helps extend or modernize what can be characterized as a legacy backend SAP platform.

SAP and Cloud (cont’d)

Pillar 3 SAP Business ByDesign- The third pillar in SAP’s cloud

strategy is its Business By Design solution. Unlike its more limited competitors, SAP explains that BBD offers the only truly broad-based, fully comprehensive ERP solution on the market.

Pillar 4 Bridging the Old and New Worlds- The fourth and

arguably most transformational pillar of SAP’s cloud strategy is related trying together public cloud capabilities like those available through Amazon web services with an SAP application platform’s native capabilities.

System Status (SICK) Monitoring

Application Servers (SM51)

Workload Distribution (SM50 and

SM66)


System Status (SICK)

• Run /nSICK to verify the overall system remains healthy.• It’s equally useful to validate that SAP’s foundation remains sound.

SICK verifies the SAP foundation is sound.

19/04/2023


Monitoring Application Servers (SM51)

Designed to ensure the availability of SAP to its end users. You can view the SAP Servers System Monitoring screen following the menu path Tools, Administration, Monitor, System Monitoring, Servers or by running transaction code /nSM51.screen displays core services (hosted by specialized work processes) provided by each instance—services earmarked for online users, batch jobs, performing database updates,and so on.

19/04/2023


Workload Distribution (SM50 and SM66)

19/04/2023

SM50 SM66

Can be used to view the status of all work processes of a specific application server.

• SM66 displays a real-time snapshot of only active work processes.• Also displays system-wide work processes rather than just the work processes associated with a single application server.


Reviewing SAP System Logs (SM21) SAP maintains system logs that record important events

that occur in your SAP system. Which system log and which tool to use to display the

events depends on whether the SAP NetWeaver application server consists of the ABAP, Java, or ABAP + Java stack.

Application Server Load (SMLG, AL08, and ST07) SMLG monitors how many users are logged on to each application server and how well SAP’s logon load-balancing mechanism is working AL08 displays every end user logged on to SAP, along with the transactions he or she is currently executing ST07 also displays the total number of dialog steps processed. It sorts users by SAP functional areas (SAP ERP FI, MM, PM, PS, SD, and so on), though, rather than by application servers as AL08

19/04/2023


SAP Application Server Buffers (ST02) Run /nST02 to monitor individual SAP application server buffers and more Beyond buffers, use ST02 to also track the size and utilization of each SAP application server’s roll area, paging area, extended memory, and heap memory (the latter of which needs to be as small as possible)

19/04/2023


Summary

Proactive SAP system administration and management are key to maintaining a highly available and well-performing system.

SAP’s very own CCMS represents an ideal starting point for such system administration and management tasks. This hour provided insight into only a few of the many tools and techniques used by SAP IT professionals to administrator and manage SAP.
