Featured MinIO reviews

Abdelrahim-Ahmad

Data Scientist at a tech vendor with 501-1,000 employees

MinIO should provide an easier subscription model for companies that don't have a huge amount of data. Our company has a maximum of 100 terabytes of data. The solution should provide more bugging tools in the open-source version to encourage people to buy the support services. It's not an easy decision. If I go to the management and tell them that I need to buy a service, there should be an easier subscription model for companies that don't have huge amounts of data. For me, getting a subscription for 15,000 a year for a system already in production might be a bit hard. I think MinIO supports a minimum of one petabyte or 100 terabytes of data. Since we don't have such huge amounts of data, buying a subscription for the solution is a bit difficult. Hence, we're only using the open-source version for now. If MinIO becomes really crucial for our business, we could ask the management to get a subscription.

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.

"MinIO is easy to install and use, especially for standalone installations."
"I use the solution's basic object storage functionalities, like AWS S3 compatible APIs and creating buckets."
"I like that if you have a problem, you can buy the home server. It is stable and robust."

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 main issue we face with MinIO is performance."
"MinIO should provide an easier subscription model for companies that don't have a huge amount of data."
"The solution should have high availability. Also, support should be quick."

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.

Reviews from Real Users

MinIO stands out among its competitors for a number of reasons. Several major ones are its flexibility, integration options, and performance.

Süleyman Fazıl Y., a senior software engineer at a tech services company, writes, “The most valuable features are that MinIO is open, it works on-premise, and is compatible with the Amazon industry which is great for finding compatible libraries in many languages which is very good for developers.”

Rebecca S., CTO at NIASE, says, “MinIO is much improved over the prior solution, updates are simple to apply, and we anticipate that future capacity requirements will be easier to meet. Our customers are using this solution to retrieve tens of thousands of objects (documents and files) per hour, and MinIO seems to be able to keep up with it.”
