Cloud Vs Bare Metal Storage Solutions: A Comparison

Cloud Vs Bare Metal Storage Solutions: A Comparison


As the amount of data produced by businesses (and consumers) continues to grow, so does the need for reliable, economical storage. With that in mind, here is a straightforward guide to cloud storage vs bare metal storage.

Cloud storage

Cloud storage is a service model where data is stored on remote servers accessed via the internet and managed by a cloud provider. These services allow users to store, retrieve, and manage their data without needing physical infrastructure.

Key characteristics of cloud storage include high accessibility, scalability, redundancy, and cost-efficiency. Users can access their data from any location with internet connectivity, and storage capacity can be easily scaled up or down based on demand.

Cloud providers typically ensure high availability and data redundancy by replicating data across multiple geographic locations.

Use cases for cloud storage

Common use cases for cloud storage include data backup and recovery, where its redundancy and accessibility ensure data safety and easy restoration. It is also popular for hosting web applications and content distribution, providing scalable storage for dynamic content and large datasets.

Additionally, cloud storage is used for collaborative work environments, enabling multiple users to access and edit documents simultaneously from different locations.

Bare metal storage

Bare metal storage refers to data storage directly on dedicated physical servers without any virtualization layer. This type of storage provides direct access to the hardware, resulting in high performance and low latency.

Key characteristics of bare metal storage include full control over the hardware, enhanced performance, and dedicated resources. Users have the ability to optimize the storage setup to meet specific performance requirements, and there is no virtualization overhead, which can enhance data processing speeds.

Use cases for bare metal storage

Typical use cases for bare metal storage involve applications that require high performance and low latency, such as high-frequency trading platforms, real-time analytics, and large-scale database management. It is also used in environments where security and compliance are critical, providing complete control over the hardware and data.

Factors to consider

Here are the five key factors to consider when evaluating cloud storage vs bare metal storage.

Performance

Cloud storage performance can vary based on factors such as network latency, bandwidth, and the shared nature of cloud resources. While cloud providers offer different performance tiers, the inherent latency of accessing data over the internet can be a limitation for latency-sensitive applications.

By contrast, bare metal storage offers superior performance due to direct access to physical hardware, eliminating the virtualization overhead. This makes bare metal ideal for applications requiring high throughput and low latency.

Scalability

Cloud storage excels in scalability, allowing users to quickly and easily scale storage capacity up or down according to demand. This flexibility is particularly beneficial for businesses with fluctuating storage needs or rapid growth.

Cloud providers handle the underlying infrastructure, making it seamless to expand storage without significant upfront investment. Bare metal storage, on the other hand, is relatively challenging to scale.

Scaling up bare metal storage typically requires purchasing additional hardware. Scaling down requires finding an alternative use for that hardware (or disposing of it). In either case, the process of scaling may lead to downtime.

Cost

Cloud storage has minimal to no up-front costs. Ongoing costs may be charged on a subscription or pay-as-you-go model. In either case, however, they will be based on usage and will reflect data transfer fees, retrieval costs, and performance tiers.

Bare metal storage typically involves significant initial costs for hardware acquisition. Ongoing costs are generally fixed for the duration of the agreement. They reflect the resources needed to keep the servers running (e.g. maintenance, power, and cooling) rather than workload.

This difference means that cloud storage tends to be more economical for short-term usage and/or variable workloads. Bare metal storage tends to be more economical for long-term usage, especially for consistent, predictable workloads.

Suitability for different data types

Cloud storage is well-suited for unstructured data, such as documents, images, and videos, due to its high scalability and redundancy. It is also ideal for backup and disaster recovery, providing offsite storage and quick data restoration.

Bare metal storage, on the other hand, is more suitable for structured data requiring high performance, such as transactional databases and applications with demanding read/write operations. It offers the control and optimization needed for specialized workloads, particularly in industries with stringent performance and security requirements.

Suitability for different workloads

Cloud storage is advantageous for workloads that benefit from distributed access, collaboration, and dynamic scaling. Examples include web applications, content delivery networks, and big data analytics, where the elasticity and global reach of cloud infrastructure can be leveraged.

Bare metal storage is better suited for workloads that require dedicated resources and high performance, such as real-time processing, high-frequency trading, and large-scale scientific simulations. The ability to fine-tune hardware configurations makes bare metal storage a preferred choice for performance-critical applications.
