I really like using this product and how it functions. > > **改善点**: I don't have any issues that I can consider a con, except that you need to be tech-savvy to deploy on the platform. > > My overall experience using Amazon S3 was great, an awesome way to host numerous websites in one place. ----- ### "Smashed Potato" — 4.0/5 > **Damian** | *2026年2月28日* | 情報技術、情報サービス | おすすめ評価：6.0/10 > > **良いポイント**: Very vercitile and easy to use storage system, which become small standard in the industry. With very easy way to implement it inside applications. > > **改善点**: I think overall pricing, comparing to other providers which implemented same "s3 compatible" storage system ----- ### "Highly reliable and scalable storage though it has a bit of a learning curve." — 5.0/5 > **Sanskar** | *2026年6月2日* | 高等教育 | おすすめ評価：9.0/10 > > **良いポイント**: The best part about Amazon S3 is its reliability and how easily it scales. Whether you are uploading small text files or massive data backups it just works without any lag. The file management and bucket system make it very easy to organize data once you get used to it. Plus the uptime is incredible I have never faced an issue where my files were unavailable when needed. > > **改善点**: The user interface can feel a bit overwhelming and technical if you are a beginner. It's not as simple as Google Drive or Dropbox right out of the box. Also understanding the pricing structure(like data transfer out fees and different storage classes)can be quite confusing at first, so you really have to monitor your usage to avoid surprise costs. > > My overall experience has been highly positive. I use it primarily for data storage and document management and it serves as a highly secure, rock-solid backend for backups. While the initial setup and AWS console have a bit of a learning curve. the value for money and the absolute peace of mind regarding data safety make it completely worth it. ----- ### "Amazon S3 review" — 3.0/5 > **Tonia** | *2023年6月23日* | 非営利団体運営 | おすすめ評価：7.0/10 > > **良いポイント**: With Amazon being such a large company, we can use multiple technologies with only one bill. Amazon is well known and does a good job at storing and retaining my data. Amazon has many more features than their competitors which is great if you know how to set them up and run them. Amazon S3 does offer free training for their products which is helpful. > > **改善点**: Amazon S3 platform is hard to navigate, I feel it is ment for an advanced user rather than someone who is trying out new technology. Amazon is a bit higher priced than many competitors. > > Amazon S3 did exactly what I wanted it to do once I got past the setup obstacles. It is a bit difficult to navagate. Amazon does offer free training for their products which is a plus. ----- ### "Powerful and versatile, perhaps not so "Simple" Storage Solution" — 4.0/5 > **Connor** | *2026年4月9日* | メディア制作 | おすすめ評価：8.0/10 > > **良いポイント**: A powerful file sharing solution included in the AWS suite of services and tools. It provides a platform that, using extended functionality (APIs, SSH, web console, etc) provides a plethora of various mediums for interfacing with files (or, 'objects') in this respect. Being part of the AWS platform means that there is almost infinite redundancy, functionality for global regional accessibility, and many more other admin settings/configs that can expand on the baseline service. > > **改善点**: As with all AWS services; nothing is as straight forward as they would have you believe from the name ("Simple" storage solution is perhaps an exaggeration). Dependencies can/do include additional configurations such as region locking (Unless you want to get fancy with advanced settings and integrating other services); IAM permissions and access keys for access (How you configure this really is use case dependent); etc - Also worth mentioning that unless you are already familiar with AWS and their suite, expect to spend a good few hours going through and navigating the platform to understand the interconnectivity between functions and services. A final note to mention that trying to specifically find an easy readable guide on best practices is a bit like finding a needle in a haystack - difficult and likely to be difficult to extrapolate for your use case (especially when integrating it with more AWS solutions). > > As with all AWS; the learning curve is more of a wall than a gentle gradient. And, following suit on the above statement - spending 100 hours on the platform configuring and setting up absolutely doesn't guarantee that you'll be setting things up best practice first thing moving forward - there are always new updates; subtle changes and new ways of working that will have you frustrated and realising you "should've/could've/woud've" ; but now it's live and in production you can't\! For all of it's miseries and hair pulling from a configuration standpoint however, the platform absolutely works seemlessly once it's set up properly and never seems to have issues with downtime, latency, or general availability. This extends from our personal experience where we have all manner of different interfaces accessing and managing the objects within S3; from end users using file connect clients to access and download/upload objects; to third party solutions accessing via API and interpreting objects in all manner of formats for automations and project managers to interface with. ----- ページ：1 / 46\ 次へ: [次ページ](https://www.capterra.jp/software/174285/amazon-s3?page=2) ## リンク - [Capterraで表示する](https://www.capterra.jp/software/174285/amazon-s3) ## このページは以下の言語で利用できます | ロケール | URL | | de | | | de-AT | | | de-CH | | | en | | | en-AE | | | en-AU | | | en-CA | | | en-GB | | | en-IE | | | en-IL | | | en-IN | | | en-NZ | | | en-SG | | | en-ZA | | | es | | | es-AR | | | es-CL | | | es-CO | | | es-CR | | | es-DO | | | es-EC | | | es-MX | | | es-PA | | | es-PE | | | fr | | | fr-BE | | | fr-CA | | | fr-LU | | | it | | | ja | | | nl | | | nl-BE | | | pt | | | pt-PT | | | sv | | ----- ## 構造化データ
