Single Instance

PreviousDeployment ModelsNextHigh Availability Deployment

Last updated 11 months ago

In the emCA certifying authority (CA) standalone deployment architecture the emca application server, OCSP server, TSA server, and DB server are located in a secure zone. The highly trusted zone contains HSM. This environment is typically isolated from the rest of the network and is only accessible to authorized personnel.

Single Instance Deployment Architecture

A single instance deployment architecture is a simplified deployment model that involves installing all components of the emCA CA application on a single individual servers for each emCA component. This approach is suitable for small to medium-sized organizations with relatively low certificate issuance volumes.

Key Components:

  1. emCA CA App Server: The core component of the emCA CA application, responsible for generating and issuing certificates, managing the CA's certificate pool, and handling certificate lifecycle events.

  2. Timestamping Authority Server: Generates timestamps for digital signatures, ensuring the long-term validity and integrity of certificates.

  3. OCSP App Server: Provides an online certificate status protocol (OCSP) responder service to verify the revocation status of certificates.

  4. emCA DB Server: Hosts the emCA database, storing information about the CA's certificates, users, devices, and other relevant data.

  5. HSM (Hardware Security Module): A tamper-proof device that securely stores the CA's private keys and other sensitive cryptographic material, protecting them from unauthorized access.

  6. Offline-emCA: An offline version of the emCA CA application, enabling certificate generation in situations where the primary emCA CA server is unavailable.

  7. Internet/Intranet: The network to which the emCA application is connected, allowing authorized clients to access and obtain certificates.

Deployment Scenario:

  • All components are installed on a single individual servers within the organization's secure zone.

  • The server is protected by a router and firewall to restrict access and enhance security.

  • Authorized users can access the application through the internet or intranet to request and manage certificates.

Benefits of Single Instance Deployment:

  • Simplicity: Easy to implement and manage due to the centralized architecture.

  • Cost-Effectiveness: Lower initial investment compared to distributed architectures.

  • Suitable for Small Deployments: Ideal for organizations with moderate certificate issuance volumes.

Considerations:

  • Scalability: This may not be suitable for large-scale deployments with high certificate issuance demands.

  • Single Point of Failure: Potential for disruption if the server experiences hardware or software issues.

  • Security: Careful configuration and ongoing maintenance are crucial to maintain a robust security posture.
