HashiCorp, a leader in multi-cloud infrastructure automation, faces the constant challenge of scaling its operations. As the company grows, so too does the volume of internal documentation – from engineering specifications and security policies to marketing materials and legal agreements. Managing this ever-expanding repository effectively became a critical bottleneck. To overcome this, HashiCorp engineers built Hermes, a custom-designed document management system tailored to the specific needs of a rapidly expanding technology company. This article delves into the architecture, functionalities, and impact of System Hermes, addressing the scaling challenges it was designed to solve. While the specifics of the system's internal workings are proprietary, we can explore the general principles and functionalities that underpin its success.
Addressing the Scaling Challenges
Before Hermes, HashiCorp relied on a patchwork of disparate systems for document management. These included shared drives, email chains, and various cloud storage solutions. This fragmented approach led to several significant problems:
* Version Control Chaos: Tracking changes and ensuring everyone was working with the most up-to-date version of a document was a constant struggle. Multiple versions existed, leading to confusion, inconsistencies, and potential errors.
* Difficult Discoverability: Locating specific documents within the sprawling landscape of disparate systems was time-consuming and inefficient. Employees often wasted valuable time searching for information that should have been readily accessible.
* Inefficient Workflow: The approval and review processes were cumbersome and lacked transparency. Documents often got stuck in the approval pipeline, delaying critical projects and decisions.
* Security Risks: The decentralized nature of the previous system posed significant security risks. Access control was inconsistent, making it difficult to ensure sensitive information remained confidential.
* Scalability Limitations: As the company grew, the existing systems struggled to keep pace with the increasing volume of documents and users. Performance degraded, and the overall system became increasingly unstable.
Hermes was designed to address all these challenges, providing a centralized, scalable, and secure solution for document management.
The Architecture of System Hermes
While the precise technical details of Hermes remain confidential, its architecture likely incorporates several key components:
* Centralized Repository: At its core, Hermes features a centralized repository for storing all company documents. This repository is likely built using a robust and scalable database system, potentially leveraging technologies like PostgreSQL or similar solutions. This centralized approach eliminates the fragmentation of the previous system and ensures all documents are easily accessible in a single location. The choice of database would depend on factors like data volume, query complexity, and transaction requirements.
* Version Control System: A sophisticated version control system is essential for any document management system. Hermes likely employs a system that tracks every change made to a document, allowing users to revert to previous versions if necessary. This ensures data integrity and prevents accidental overwrites. Git or a similar distributed version control system might have been adapted for this purpose, or a purpose-built solution might be in place.
* Workflow Engine: The system incorporates a workflow engine to manage the document approval and review processes. This engine automates the routing of documents to the appropriate reviewers and approvers, ensuring timely processing and maintaining transparency throughout the workflow. This could involve custom-built logic or the integration of a pre-existing workflow management system.
