1. Introduction: Why Service Central Matters

Nutanix Central is a unified management portal that consolidates and simplifies the oversight of multiple Prism Central (PC) instances, spanning datacenters, geographies, and tenants. For organizations managing complex environments, Service Central is the key to streamlined operations, consistency, and scalable governance.

---

2. Prerequisites and Planning

Before deploying Service Central, prepare the following:

• Supported Versions: Latest LTS or STS version of Prism Central and AOS.
  • Nutanix Central requires Prism Central version pc.2023.4.0.2 or later
  • Refer to the Nutanix Compatibility Matrix.
• Network Requirements: Layer 3 connectivity between Service Central and all PC instances, required ports open (refer to the Nutanix Port Reference).
• DNS and NTP: Ensure reliable name resolution and time synchronization across all nodes.
• Access & Authentication: Service account(s) with cluster admin privileges, integration readiness for AD/LDAP, SSO, and ServiceNow (if used).
• Resource Planning: CPU, memory, and storage sizing per Nutanix’s Service Central deployment guide.
• Security: Firewall exceptions for control, API, and monitoring traffic.
• Backup: Backup plan for PC and Service Central VMs.

---

3. Deployment Architecture: Multi-Site and Multi-Tenant

Service Central supports:

• Multi-site: Manage multiple datacenters/edge locations.
• Multi-tenant: Delegate control and visibility to different business units or customers.

4. Implementation and Configuration (Step-by-Step)

A. Registering Prism Central Instances

1. From the Service Central dashboard, click “Add Prism Central.”
2. Enter FQDN/IP, admin credentials, and connection name.
3. Repeat for each site.
4. Group PCs by site, tenant, or function as needed.

B. Enabling SSO/AD Integration

1. Navigate to Settings > Authentication.
2. Select Active Directory or LDAP.
3. Provide directory server details, bind DN, and credentials.
4. Map roles to AD groups (e.g., Admins, Operators, Auditors).

C. ServiceNow Integration

1. Under Integrations, select ServiceNow.
2. Provide ServiceNow instance URL, credentials, and mapping fields.
3. Configure workflows for ticket automation, event ingestion, and reporting.

5. Centralized Management for All Prism Central Instances

With Service Central, you can:

• Unified Inventory: See all clusters, VMs, storage, and network objects from every registered PC.
• Policy Propagation: Push configuration, security, and monitoring policies to multiple sites in one step.
• Event & Alert Aggregation: Central dashboard for real-time alerts and audit logs.
• Role Delegation: Assign admins to specific sites/tenants without full environment access.

6. Integration with AD, ServiceNow, and External Services

• Active Directory/LDAP: Centralize user and group management. Automate onboarding/offboarding. Enforce MFA via SSO.
• ServiceNow: Automated incident, change, and asset management. Real-time event forwarding. Custom workflow triggers.
• Syslog/SIEM: Stream audit logs to external SIEMs (Splunk, QRadar).
• Email/SMS: Alert routing for proactive monitoring.

---

7. Governance, RBAC, and Delegation

• Role-Based Access Control (RBAC): Assign roles (viewer, operator, admin) per site, tenant, or group.
• Delegation: Limit privileges to business units, ensuring least-privilege access.
• Governance: Centralized audit logs, approval workflows, and policy change tracking.

Sample Workflow Table:

Role	Scope	Permissions	Approval Needed?
Site Admin	Site A	Full	No
Tenant Op	Tenant X	Start/Stop VMs	Yes
Auditor	All	Read-only	No

---

8. Automation and Scripting Examples

A. API: Registering a Prism Central Instance

curl -X POST "https://<service-central>/api/v1/prism-central/register" \
  -H "Content-Type: application/json" \
  -d '{"fqdn":"pc.sitea.corp","username":"admin","password":"<pwd>"}'

B. PowerShell: Bulk Add Prism Centrals

$pcs = @("pc1.domain.com","pc2.domain.com")
foreach ($pc in $pcs) {
  Invoke-RestMethod -Uri "https://servicecentral/api/v1/prism-central/register" `
    -Method Post `
    -Body @{fqdn=$pc; username="admin"; password="securepwd"} | Out-Null
}

C. Nutanix Calm/Automation

• Use Calm blueprints for repeatable deployments.
• Automate upgrades and backups with Nutanix APIs.

---

9. Monitoring, Alerting, and Reporting

• Dashboards: Customizable real-time views across all sites.
• Alerting: Route alerts to email, ServiceNow, or SIEM.
• Reporting: Schedule and export health, inventory, and compliance reports.

Sample CLI:

curl -u admin:pwd https://<service-central>/api/v1/alerts

---

10. Migration Playbook: Onboarding Legacy Instances

Pre-Migration Assessment

• Inventory: Document all legacy Prism Central instances, versions, clusters, and integrations.
• Compatibility Check: Validate firmware, software versions, and feature support in the Nutanix Compatibility Matrix.
• Backup: Take full backups and export configurations from each legacy PC before migration.

Step-by-Step Migration Process

1. Network Prep: Ensure L3 connectivity and DNS resolution between legacy PCs and Service Central.
2. Registration:
   • Log in to Service Central, select “Add Prism Central”.
   • Enter details for each legacy instance.
3. Policy Mapping: Review current RBAC, security, and monitoring policies. Adjust for central management if necessary.
4. Test Integration: Validate connectivity, inventory sync, and alerting from each legacy PC.
5. Stakeholder Review: Confirm new workflows and delegated access with IT and business units.
6. Cutover: Transition active management to Service Central.
7. Decommission Legacy Management Tools: After a stable transition period, remove or archive old management utilities.

Rollback Plan

• Maintain parallel access to legacy PCs until post-migration validation is complete.
• Document rollback steps: unregister from Service Central, restore backups, and revert DNS/routing changes if required.

Migration Automation (Sample Script):

# Demostration-API example
for pc in $(cat pc_list.txt); do
  curl -X POST "https://servicecentral/api/v1/prism-central/register" -d "{\"fqdn\": \"$pc\", \"username\": \"admin\", \"password\": \"***\"}"
done

Pro Tip:

Pilot migration with a non-critical site before full-scale rollout to identify and address any unforeseen challenges.

11. Security Hardening and Compliance

Identity and Access Management

• Integrate with AD/LDAP/Azure AD: Enforce enterprise-level authentication and group mapping for RBAC.
• Multi-Factor Authentication (MFA): Enable MFA for all privileged accounts. Integrate with SSO where possible.
• Principle of Least Privilege: Regularly review permissions and limit admin-level access only to necessary personnel.

Network and Data Security

• TLS Everywhere: Require TLS for all management traffic (including API endpoints).
• Firewalling: Restrict Service Central access to trusted management networks only. Block unnecessary inbound/outbound ports.
• Management Network Segmentation: Place Service Central in a secure, dedicated management VLAN.

Audit and Compliance

• Enable Audit Logging: Forward logs to a SIEM or centralized syslog server (e.g., Splunk, QRadar).
• Regular Reviews: Audit user activity, policy changes, and failed login attempts at least monthly.
• Security Patch Management: Monitor Nutanix advisories, apply patches and updates promptly.

Compliance Frameworks

• PCI DSS, HIPAA, GDPR, SOC2: Map Service Central controls to relevant regulatory requirements. Use Nutanix documentation and compliance guides.
• Data Retention Policies: Configure log retention to meet compliance needs.

Pro Tip:

Use Nutanix Security Central (if licensed) for ongoing risk analysis, compliance dashboards, and automated policy enforcement.
