Planning Your Implementation

Plan your architecture, deployment best practices, and operational responsibilities before installing Sonatype Nexus Repository. The choices you make early may affect scalability, performance, security, cost, and maintainability. This section will guide you through the major decisions and trade-offs.

Key Consideration Areas

Focus on the following areas when planning your Nexus Repository deployment. Each represents a critical design or operational decision that will affect stability, scalability, and long-term maintainability.

Architecture and Deployment

Reference Architecture: Review reference architectures that illustrate how to size and structure a deployment. These architectures provide tested blueprints that balance performance, scalability, and stability.
Deployment Pattern Library: Explore common deployment patterns that emphasize resiliency, scalability, and distribution. Patterns show how to combine features for different organizational needs.
Database Options: Review database options that are available for Sonatype Nexus Repository. Guidance covers using the embedded database or connecting to an external PostgreSQL instance.
Storage Guide: Plan your blob storage strategy. This section explains available storage types and configuration options. Note that many attributes of Blob storage are inflexible.

Resiliency and Availability

Resiliency: Design a system that continues operating during hardware, software, network, or datacenter disruptions. The resiliency section outlines strategies to minimize downtime.
High Availability Deployment: Deploy Nexus Repository in high-availability mode. This section covers pre-requisites, post deployment steps and validation.

Security and Operations

Reverse Proxy: Learn why and how to run Nexus Repository behind a reverse proxy. A proxy can add security, manage traffic, and simplify TLS termination.
Repository Security: Apply best practices to protect your Nexus Repository.
Controlling Costs: Plan for disk space management. This section covers cleanup policies, tasks, and REST calls to cleanup complex scenarios.
Backup and Restore: Ensure business continuity with a backup and restore plan. This section explains configuring backup tasks, preparing backup, and restoring backups.
