Valuable Features

MinIO offers ease of management, powerful performance, and a user-friendly interface. Users value its flexibility for spawning and shutting down tenants, robust SDK support, and superior administration tools. It ensures high retrieval performance and seamless updates. The UI aids in data exploration, while compatibility with Amazon S3 APIs enhances integration. Notable features include erasure coding, low memory usage, open-source nature, hybrid environment support, and smooth deployment. Users appreciate its reliable coding protection and even workload distribution.
  • "The initial setup was straightforward as MinIO provided good support documentation and took a couple of days to complete."
  • "This is an all-in-one, user-friendly data storage solution."
  • "We use MinIO for enterprise file storage."

Room for Improvement

MinIO requires enhanced monitoring tools, better multi-tenancy, and improved documentation. Users report challenges with initial configuration, high availability, and support. Performance issues arise with large datasets. Monitoring REST API, graphical bucket search, expanded storage capabilities, and a robust user interface are needed. Complex SSL setup and slow heal function are also areas for improvement. The free version's storage limits, pricing model, and integration without third-party tools are additional concerns. Enhanced OpenShift and non-container support are desired.
  • "The developer support could be better."
  • "I feel there is a lack of good addons to integrate without having to use third-party applications."
  • "The scalability is one of the limitations we have found. We are looking for another solution but they must provide the same characteristics, such as an affordable price and continuity."

Pricing

MinIO offers an open-source solution free of cost, but enterprises can opt for a licensed version to access support and enhanced features. Many organizations utilize the free version initially and transition to the licensed version post-validation and stabilization. Costs align with similar market solutions, and additional expenses include hardware investments, such as VMware hosts and storage area networks. Pricing for commercial use is considered reasonable by users familiar with comparable products.
  • "We use the solution's open-source version."
  • "My company hasn't tried the version of the solution where we need to pay to use it."
  • "We use the solution's open-source version."

Popular Use Cases

MinIO is widely utilized for storage across various domains, serving machine learning artifacts, microservices with .NET Core, document management for legal cases, and unstructured data. It acts as a data link, cloud-native gateway, and tool for file storage in Kubernetes clusters. Many integrate it for file-sharing, document versioning, and object storage. Users praise its scalability and performance, leveraging it as an alternative to Amazon S3 for mid-sized datasets and securing data with S3 API credentials.

Service and Support

Users in Iran face restrictions due to sanctions and rely on community support, while others use forums and community channels like Slack for assistance. Official documentation is often seen as lacking. Many prefer community-based solutions given MinIO's open-source nature. There's appreciation for community assistance, though responses can be slow. Some note MinIO's small team limits direct support availability. Individuals using MinIO without paid support find community interactions adequate for general issues.

Deployment

MinIO's initial setup experience varied. Some found it straightforward, taking minutes to hours, especially with small clusters or Helm charts. Others faced complexity with Kubernetes, requiring weeks. Teams often used DevOps support, with roles like network engineers and Linux experts involved. Terraform and Ansible playbooks aided deployment, though challenges arose with MinIO Client configuration and documentation. Upgrades were frequent, and successful deployment depended on expertise in Linux and storage technologies.

Scalability

MinIO is generally considered scalable, with users noting easy scaling with Kubernetes and scale-out architecture. Some encounter challenges with large-scale data and manual cleanup in certain environments. Issues arise in automation and performance scalability for big data. Clustering deployment and node addition are noted, though some limitations are present. MinIO supports development teams and integrates well with existing systems, although performance may vary based on data demands. Customers appreciate the ability to expand usage and storage.

Stability

MinIO is mostly stable, widely used daily, and performs well under load. Some have experienced occasional latency issues and unexpected downtimes, particularly in Kubernetes environments. Dependencies on the underlying OS and file systems contribute to crashes. Users report minimal maintenance needs and effective operation without outages. The system's stability is positively highlighted, with ratings often reaching nine or ten, though specific cases of performance degradation during heavy data processing have been noted.

MinIO Reviews Summary
Author infoRatingReview Summary
Data Scientist at a tech vendor with 501-1,000 employees4.5I find MinIO to be a suitable locally-hosted object storage system similar to Amazon S3. While its performance is satisfactory for mid-sized datasets, I wish for a more accessible subscription model for smaller data needs and enhanced open-source bugging tools.
Head of Data Science center of excellence at Ameriabank CJSC3.5We use MinIO as a cloud storage solution for our data science team, valuing its S3 API integration and ease of use. However, performance issues with I/O capabilities affect usability during extensive data operations, especially with big data.
Vice President, Artificial Intelligence at DLytica Inc.4.0My company utilizes MinIO primarily for storage as an Amazon S3 alternative, benefiting greatly from its hybrid environment capabilities. Despite minor installation challenges with OpenShift, the solution saves time, although ROI specifics are unclear since we use its open-source version.
Chief Technical Officer at NIASE3.5As a CTO, I find MinIO offers improved retrieval performance and easy updates for our 7 million legal documents. However, documentation for clustering/Linux is poor, and the web UI/Prometheus struggle with large buckets, needing workarounds.
Senior Operation Manger at Thai Trade Net4.0I appreciate MinIO's stability and robustness, especially its ability to integrate with another connector. However, I believe it needs high availability and faster support. Overall, it's user-friendly, providing easy deployment.
Data Engineer at Mofid4.0We use MinIO for object storage in our core platform, finding it ideal as a data lake solution. It's easy for DevOps executives to use and maintain, offering superior performance. However, distributed non-container applications and reverse proxy features need improvement.
Founder & CEO at Unikrew Solutions4.0We use MinIO to manage document versioning and video KYC recordings for loan processes. Its easy integration and features like versioning and role management are valuable, but pricing, Kubernetes deployment, and documentation need improvement. Deployment is currently standalone.
Senior Architect - Technology Consulting at Ernst & Young4.0I use MinIO for unstructured data, finding its setup straightforward, stability, and scalability good. While documentation helps, developer support needs improvement. It's a better alternative to expensive Hadoop.
