Block Storage Use Case: Database Storage

Leave your reply

Introduction

Learn how 1&1 IONOS Block Storage can be integrated with a database solution to extend an application, increase performance, and provide a fail-safe in case of server issues. Block Storage is an easy way to add fast, efficient storage space to a Cloud Server. Block Storage is managed like a hard drive. You can easily resize a Block Storage volume, remove it, or assign it to a different Cloud Server.

Use Case: Database Storage

The user in the following examples has a high-traffic, database-driven website. The database stores and manages user-generated content, and is quite large. In addition to increasing the throughput and availability of the database, the user would like a solution which can easily grow to accommodate the database as it increases in size.

To set the stage for the following scenarios, the user creates a Block Storage device, and attaches it to their web server. Then the user configures their database so that its data is stored on the Block Storage device.

By off-loading the database to the Block Storage device, the user frees up server capacity on the web server. This provides a significant increase to the website's performance.

Scenario 1: High Availability

A 1&1 IONOS Block Storage device is a device which is separate from the Cloud Server to which it is attached. Much like an additional hard drive, the Block Storage device can be attached, detached, and reattached to a different server as needed.

If the user's web server experiences problems, or the user needs to perform maintenance on the server, the Block Storage device can simply be detached from the original server and attached to a new server.

Scenario 2: Migration

In this scenario, the user has decided to migrate their site to a new server with a different operating system. The Block Storage device can be easily detached from the original server and attached to a new server. This provides a quick, secure way to painlessly migrate the entire database to a new server.

Scenario 3: Expansion

As the user's website gains popularity and traffic, the database continues to grow, and the demands on the website increase. Eventually, the user decides that a single web server is not sufficient to handle the demands of their traffic.

There are several possible configurations which can greatly increase the user's performance. One popular solution is to use a Load Balancer to provide load balancing between multiple web servers.

In this configuration, each web server is attached to its own Block Storage device. The user leverages the database's built-in replication methods to keep the database information on the Block Storage devices in sync.

This configuration, which consists of pairs of web servers and Block Storage devices, can easily be built out as necessary in the future.
