Block Storage

Why choose block storage?

Scale Volumes Instantly on Demand

Tailor the performance precisely to your workloads – with the Essential, Balanced and Performance classes with up to 24 volumes per virtual machine and up to 4 TB per volume (more on request).

High Performance in Small Instances

Use exactly the storage configuration you need. Combine different performance classes and benefit from high performance – even in small setups.

Multi-AZ Deployment (Three Zones)

Provision all performance classes across zones. This enables continuous availability and disaster recovery.

Double Redundancy & High Availability

Maximum reliability through dual redundancy: Your data is not only stored on a local RAID, but is also synchronously mirrored to physically separate storage servers. The result is maximum reliability for your business-critical applications and therefore high availability of your data.

Transparent prices

Regardless of your chosen storage configuration, you only ever pay for the booked capacity and the respective period that you actually use.

Snapshots and Cloud Backups

Shorten your backup windows and access snapshots on demand, which you can create for any volume type and use across platforms. Tip: With the IONOS CLOUD Backup-as-a-Service solution, you can also store your data in US data centers

Block Storage: Performance Classes at a Glance

IONOS CLOUD Block Storage offers maximum performance, minimal latency, and superior security. Flexibly combine storage technologies (hybrid storage) on enterprise hardware. Your data is always located on physically distributed systems for maximum business continuity.

Your benefits:

  • Cost-effective storage for defined use cases
  • Double redundancy: Each instance also runs on separate storage servers
  • Performance included: Independence from IOPS and compute configurations
  • Optional: Data backup with Backup as a Service, including  backup agent
  • On request: Automated storage monitoring in our Monitoring-as-a-Service solution

Uses cases for IONOS CLOUD block storage

Use case

Transactional Databases

Achieve top performance for business-critical applications and transactional databases thanks to high IOPS – at transparent prices. Dual redundancy ensures reliable operation, while hybrid storage technologies allow you to flexibly adapt your setup. Scale flexibly as needed and optimize your setup precisely for your use case by intelligently combining individual storage technologies.

Use case

Virtualized RAID Data Backup

Combine multiple volumes into a single instance and virtualize your data backup. Benefit from double redundancy and significantly higher I/O performance.

Use case

Scalable Mail Servers & Exchange

Operate high-performance, data protection-compliant email servers. Block storage adapts to your requirements and, thanks to the absence of I/O limitations (high IOPS), ensures significantly faster data access than network-based systems.

The benefits of the IONOS CLOUD

No vendor lock-in

IONOS CLOUD solutions and products won’t make you dependent on any vendors. The IONOS CLOUD offers open-source solutions that are not vendor-controlled.

Usage-based billing

Cloud computing resources and services usage are billed according to usage, down to the minute.

Sustainability

The IONOS CLOUD is a climate-neutral cloud platform that relies on a combination of renewable energy sources and energy-efficient hardware and software.

Exceptional quality

IONOS CLOUD offers unbeatable price/performance benefits

IONOS CLOUD is regularly put to the test in independent market analyses such as the ISG Provider Lens™. IONOS CLOUD is consistently on track to maintain its top position in the top-4 leading companies in the industry.

In 2020, IONOS CLOUD also impressed the independent US consulting firm Cloud Spectator, beating the competitors AWS, Azure and Google in the areas of compute and storage performance as well as in price/performance ratio.

IONOS CLOUD was announced as the winner of the Cloud Service Provider Platinum Award at the Service Provider Summit 2021.

IONOS CLOUD also won the Gold Award in the Infrastructure as a Service category at the Cloud Computing Insider Awards in 2021.
