Versatile data storage improves security and supports increasing data volumes
Amazon S3 Glacier offers robust security features and practically infinite storage, where we can store all kinds of media swiftly. It supports various data types, including semi-structured and raw formats. These features facilitate log management and data dumping since the service is versatile enough to handle large volumes of data and provide necessary security.
Ajai Jayakumar - PeerSpot reviewer
Solution Architect at a computer software company with 501-1,000 employees
Has supported secure file sharing and data automation with minimal setup effort
The encryption feature in Microsoft Azure Block Storage is very good, and the security is excellent. It is easy to map the storage to the virtual servers and user desktops, which is also very beneficial. I can perform automations on the data, such as moving hot data and cold data, and I can select storage based on performance. The security provided by Microsoft around Microsoft Azure Block Storage is a very good function. The replication feature in Microsoft Azure Block Storage is a very good function. The analytic capabilities of Microsoft Azure Block Storage can help optimize resources. I usually work with a third-party tool; our data analytics team uses some custom-made tools for analytics data and dashboards, so we do not use the Microsoft dashboard; we are using a third-party dashboard. It is very easy to manage Microsoft Azure Block Storage. If you have good knowledge of it, it is very easy to manage. Microsoft Azure Block Storage service is a very good, 100% reliable service. It is highly scalable, and performance-wise and reliability-wise, it does not go down. It provides 99.9% uptime without downtime, so it is a very good feature. The backup and restoration efficiency of Microsoft Azure Block Storage is good.
