The Enterprise Hybrid Cloud for Solution has been updated to 3.5 a couple of weeks ago, so let’s take a look at SAP specific enhancements to this release, especially the current architecture, integration points, self-service SAP provisioning, NSX as well as SAP monitoring and root cause analysis with the help of vRealize Operations and ViPR SRM.
Let’s start with the Enterprise Hybrid Cloud technology components as part of the overall architecture:
The figure below shows the EMC, VMware, and SAP integration points. The blue boxes represent the Enterprise Hybrid Cloud components, the orange box represents the application components, the green boxes represent the integration points to EMC components and the gray boxes the integration points to VMware components.
SELF-SERVICE SAP PROVISIONING
Cloud users can request and manage SAP applications and compute resources within established operational policies, reducing IT service delivery times from days or weeks to just minutes. Here is a sample Enterprise Hybrid Cloud catalog for SAP:
The Enterprise Hybrid Cloud can use NSX for vSphere to offer significant advancements over the vCloud Networking and Security feature set, such as:
- Distributed logical switches—Distributed logical broadcast domains/segments that can span across multiple clusters and to which a VM can be logically connected/wired. This allows for VM mobility without concern for traditional physical Layer 2 boundaries.
- Distributed logical routers and firewalls—Contain East-West traffic within the hypervisor when the source and target virtual machines reside on the same host.
- Advanced network services: Load balancer, NAT, VPN—Enables load sharing across a pool of virtual machines with configurable health-check monitoring and application-specific rules for service high availability, URL rewriting, and advanced Secure Sockets Layer (SSL) handling. A distributed firewall enables consistent data-center-wide security policies.
- Security policies—Can be applied directly to security groups, enabling greater flexibility in enforcing security policies.
The logical network topology is designed to address the requirements of enabling multitenancy and securing separation of tenants and business groups in Enterprise Hybrid Cloud. The topology is also designed to align with security best practices for segmenting the networks according to the purpose or traffic type.
The figure below shows the logical topology of the physical and virtual networks that are defined in the Enterprise Hybrid Cloud solution for SAP.
For our validation we used the following sample segregation scenario:
In this scenario we demonstrated that Enterprise Hybrid Cloud can block all external connectivity outside its business group/tenant whereas it is flexible enough to allow exceptions to the rules.
SAP MONITORING AND ROOT CAUSE ANALYSIS
Using multiple management interfaces to gather performance and capacity information is not a practical solution when you maintain tens to hundreds of SAP systems The challenge of maintaining multiple SAP systems requires end-to-end visibility (from back-end infrastructure to SAP application level) across the entire cloud.
SAP tenant administrators can use role-based performance dashboards to analyze individual metric behaviors and determine the health of an enterprise, in part or as a whole.
Blue Medora vRealize Operations Management Pack for SAP CCMS enables vRealize Operations Manager to collect health and performance metrics that are taken from the SAP CCMS (transaction code RZ20). It provides a unified view of the health, risk, and efficiency of the infrastructure and the SAP applications. Real-time monitoring, which is displayed as widgets, improves the quality of service and provides early detection of issues that are related to performance, capacity, and configuration.
For fast root cause analysis this can be combined with ViPR SRM which provides end-to-end visibility as shown in this example:
