Database hosting

Database hosting demands fast storage and ample memory, since databases are I/O- and memory-intensive, plus the reliability and durability that data everything depends on requires. It needs backups, replication for availability, and dedicated resources free of noisy neighbours. Self-hosting on dedicated, EU-hosted hardware gives control, performance, and European sovereignty over the data.

Key points

  • Databases are I/O- and memory-intensive, so fast storage and ample RAM matter most.
  • Applications depend on the database, so its reliability and availability are critical.
  • Data must be durable — protected by backups and often replication against loss.
  • Dedicated resources avoid the noisy-neighbour effect that degrades shared database performance.
  • Self-hosting on EU hardware gives control and European sovereignty over the data itself.

What does database hosting need?

A database is where an application's data lives, and hosting one well means providing for performance, reliability, and durability together, because so much depends on the database. Databases are demanding in specific ways: they are heavy on storage input/output and on memory, they must be reliable because the applications above them depend on them, and their data must be durable because losing it is often catastrophic. Database hosting therefore has to provide fast storage and ample memory for performance, a reliable foundation for availability, and the protection that keeps data safe — a combination shaped by what databases specifically stress.

Getting this right matters because the database is frequently the foundation an application stands on, and its performance and reliability set limits on the whole system. A slow database makes the application slow; an unavailable database makes it unavailable; lost database data can be irrecoverable. So the infrastructure beneath a database is consequential, and specifying it means attending to the storage, memory, reliability, and data protection that databases need. This page looks at database hosting in general; the specifics of particular database systems are covered on their own pages.

Performance: storage, memory, and CPU for databases

Database performance is dominated by storage and memory, because databases read and write data constantly and benefit greatly from holding data in memory. Fast storage matters because databases perform many input/output operations, and slow storage bottlenecks them — which is why fast NVMe storage, with its high throughput and many input/output operations per second, suits databases far better than slower storage. Ample memory matters because databases cache data in memory to avoid slower storage access, so more memory lets more data be served quickly from memory, often improving performance markedly. For databases, storage speed and memory capacity are usually the first performance levers.

Processor performance also plays a part, since databases do computational work in processing queries, but for many workloads the storage and memory are the binding constraints. The balance depends on the workload: read-heavy workloads benefit greatly from memory for caching; write-heavy workloads stress storage; complex queries use more processor. Sizing database infrastructure means matching fast storage, sufficient memory, and adequate processing to the workload, with particular attention to storage and memory because they most often determine database performance. We size these to the actual database workload, since a database starved of fast storage or memory underperforms regardless of other resources.

Reliability and availability

Because applications depend on their database, the database's reliability and availability are critical — when the database is unavailable, the applications relying on it typically cannot function. The database is often a central dependency, so its downtime cascades into the downtime of everything above it, making database availability important to the whole system's availability. This means database hosting has to be reliable, built so the database stays available, because its failure has consequences well beyond the database itself.

Achieving database availability involves reliable hosting and often replication for failover. Reliable hardware in a dependable datacenter provides a sound foundation; and replication — maintaining copies of the database that can take over if the primary fails — lets the database survive a failure by failing over to a replica, keeping it available. The appropriate arrangement depends on how critical the database is and how much downtime is tolerable. When we host databases, providing for this reliability and, where needed, replication for availability is part of serving the workload, because the database's availability underpins the availability of everything that depends on it.

Data durability: backups and replication

Database data must be durable, because losing it is often catastrophic — the data an application depends on, accumulated over time, can be irreplaceable, so protecting it against loss is a central requirement of database hosting. Data can be lost to hardware failure, error, or disaster, and guarding against this requires deliberate protection: backups that let data be restored, and often replication that keeps additional copies. Durability is not automatic; it comes from arrangements made to protect the data, which are essential for a database holding anything important.

Backups and replication serve related but distinct roles in protecting data. Backups are copies taken so that data can be restored after loss, error, or corruption, providing a way back to a known good state; replication maintains live copies of the database, which supports both availability, by allowing failover, and durability, by holding the data in more than one place. A sound approach usually combines both — replication for availability and rapid recovery, and backups for restoration after errors or corruption that replication would propagate. When we host databases, providing for this data protection is essential, because the durability of the data is often the most important thing about a database, and it must be deliberately safeguarded.

Dedicated resources and the noisy-neighbour problem

Databases are sensitive to the noisy-neighbour problem — where other workloads sharing the same hardware consume resources and degrade a database's performance — which is why dedicated resources suit databases well. On shared infrastructure, other tenants' activity can contend for the storage input/output, memory, and processor a database needs, causing its performance to vary unpredictably as neighbours come and go. For a database, whose performance the whole application depends on, this variability and contention are real problems, since consistent database performance matters.

Dedicated resources — a database on hardware it does not share with other tenants — avoid this by giving the database the full, uncontended use of its storage, memory, and processor. This provides consistent, predictable performance, free of the interference shared infrastructure can bring, which is valuable for databases whose performance must be dependable. Bare-metal or dedicated hosting for databases is favoured for exactly this reason: the database gets its resources to itself. We host databases on dedicated resources so that their performance is consistent and uncontended, which suits the sensitivity of databases to the resource contention that shared infrastructure can impose.

Self-hosted versus managed database services

A common choice is between self-hosting a database on infrastructure you control and using a managed database service run by a provider. A managed service is convenient — the provider runs the database, handling much of the operational work — which is valuable, but carries trade-offs: your data sits on the provider's platform, you depend on their pricing and terms, and you have less control over the configuration and the environment. Self-hosting a database on infrastructure you control requires doing more of the operational work but keeps the database, its data, its configuration, and its jurisdiction in your hands.

The honest basis for choosing is what you value. If minimising operational effort matters most and placing your data on the provider's platform is acceptable, a managed service may suit you, and we will not pretend otherwise. If control over the database and its configuration, predictable cost, and keeping the data on infrastructure you control — including under a chosen jurisdiction — matter more, self-hosting delivers them, which is what we host. Organisations often self-host databases when the data is sensitive enough that its jurisdiction and control matter, or when the cost or configuration control of self-hosting is preferable. We provide the dedicated infrastructure for self-hosting, while acknowledging that for some, a managed service's convenience is the right trade.

Security and data sovereignty

A database often holds an application's most sensitive data, so securing it and controlling where it resides are important. The data in a database — personal data, business data, whatever the application handles — is frequently sensitive and regulated, making the database's security and the jurisdiction of its data real concerns. Securing the database, controlling access to it, and knowing where its data resides are therefore part of hosting databases responsibly, especially where the data is sensitive or subject to data-protection requirements.

This is where self-hosting on EU infrastructure serves sovereignty and control. VV Internet Hosting is incorporated in the Netherlands, within the EU, so a database self-hosted with us keeps its data under European jurisdiction and outside the direct reach of the US CLOUD Act, on infrastructure you control. For databases holding personal, sensitive, or regulated data — as many do — keeping the data in the EU on controlled infrastructure keeps it under European law and in your hands, rather than on a provider's platform under another jurisdiction. For organisations to whom the sovereignty and control of their database data matter, self-hosting on EU infrastructure addresses both, which is a substantive reason to host databases this way.

Where VV Internet Hosting fits — and where it does not

We host dedicated infrastructure for self-hosting databases: fast NVMe storage and ample memory sized to the workload, dedicated resources free of noisy neighbours, reliable hosting with replication and backups for availability and durability, in EU datacenters under European jurisdiction. This suits organisations self-hosting databases that want performance, control, and European data sovereignty on a foundation they command. For that, we are a strong fit, and we will size the storage, memory, and reliability arrangements to the database workload and its importance.

We are clear about our limits. We provide the dedicated infrastructure you run your database on; we are not a fully managed database service that operates the database for you, handling its administration, tuning, and updates as a service. If you want a managed database where the provider runs everything, that is a different kind of offering. We are the dedicated, sovereign infrastructure on which you self-host and operate your database — suited to those who want control, performance, and European sovereignty, and not a replacement for a fully managed database service. If self-hosting on infrastructure you control fits your needs, we can host it well; if you want a fully managed database, we will be clear that is a different service.

Questions

Database hosting, answered plainly

Common questions about hosting for Database hosting.

What matters most for database performance?

Usually storage speed and memory. Databases perform many input/output operations, so fast NVMe storage avoids bottlenecking them; and they cache data in memory to avoid slower storage, so ample RAM lets more be served quickly from memory. Processor matters for query processing, but storage and memory are most often the binding constraints — size them to the workload.

Why do databases suit dedicated resources?

Databases are sensitive to the noisy-neighbour problem — other workloads sharing the hardware contend for the storage, memory, and processor a database needs, degrading its performance unpredictably. Dedicated resources give the database uncontended use of its resources, providing consistent, predictable performance, which matters because the whole application depends on the database performing dependably.

Should I self-host a database or use a managed service?

It depends on what you value. A managed service is convenient but places your data on the provider's platform, with less control. Self-hosting keeps the database, data, configuration, and jurisdiction in your hands, at the cost of more operational work. Organisations often self-host when the data's sensitivity, sovereignty, or the control and cost of self-hosting matter more.
