Differences Between Business and Personal Hosting

There are clear differences between business hosting and personal hosting. If you choose a personal hosting plan by looking only at price, you may regret it later.

Support Structure

Business hosting services offer a much more substantial support structure.

In most cases, they provide phone support in addition to email and chat support. Depending on the hosting company, support is available every day of the year. Personal hosting services rarely provide support at that level.

When something goes wrong, website operation and email operation directly affect a company's credibility. That is exactly why extensive support is one of the defining features of business hosting.

Backup Systems and Security Features

Business hosting services generally have stronger backup systems and stronger security features than personal hosting services.

In general, they retain more backup generations than personal hosting services do.

They also naturally include up-to-date security measures such as WAF and IPS. In addition, email security is comprehensive as well, with measures such as virus scanning and encrypted communication.

Uptime

Unlike personal hosting services, business hosting services usually come with published uptime results or an uptime guarantee. Most of them either report or guarantee uptime of 99.99% or 100%. With personal hosting, uptime is often not disclosed at all.

A high uptime figure shows the true capabilities of a hosting company. It cannot be achieved unless every part of its operation, including infrastructure, security measures, and backup systems, is maintained at a very high level.

Email Features

Business hosting services offer more comprehensive email features than personal hosting services. It is not just email security. They also provide many useful functions, such as unlimited account creation, generous mailing list limits, and safeguards against accidental sending mistakes.

How to Choose Hosting for Small Businesses and Corporations

Because there are so many hosting services for small businesses and corporations, it is natural to wonder which one to choose. In reality, however, you can choose the right server by focusing on just three key points.

Set Your Budget

First, decide on your budget. Even if you want a high-quality server with excellent support, you cannot use it if it is outside your budget.

Because price and quality are related to a certain extent, here is a rough guide to monthly hosting price ranges.

• Low-priced: 1,000 yen or more per month, with an uptime guarantee
• Mid-range: 2,400 yen or more per month, with a well-developed support structure
• High-priced: 3,600 yen or more per month, offering top-level functionality, performance, and support across the board

Choose the monthly hosting cost your company can comfortably allocate from the ranges above. On top of that, annual domain costs and other option fees may also apply.

Hikaru Ono

If the monthly price is under 1,000 yen, the service often does not reach a business-grade level of quality, so I do not recommend it very strongly.

Whether You Also Plan to Run Email in Addition to Your Website

If you plan to run email in addition to your website, choose a hosting company that lets you manage your domain in one place.

When your domain can be managed together with the server, you can avoid unnecessary management complexity and reduce wasted costs.

Some hosting companies make the domain free when you sign up for the server, so add those to your shortlist if you want to keep costs down.

Choose by the Support Structure

Look carefully at the support structure. Do they support you every day, or only on weekdays? If no one in your company is familiar with servers, choose a provider with a stronger support system.

Some services, such as CPI, can provide 24/7 support if you pay an additional fee.

Frequently Asked Questions About Hosting for Small Businesses and Corporations

Here are the most common questions about hosting for corporations and small businesses.

How Much Do Server and Domain Costs Usually Run?

Hosting costs are generally around 20,000 to 60,000 yen, and domain costs are roughly 5,000 yen.

What Is the Difference Between Hosting and an Internet Provider?

Hosting stores data, while an internet provider offers the internet connection service that transfers that data.

What Expense Category Should Hosting Be Booked Under?

For accounting purposes, hosting fees are generally booked under communication expenses or advertising expenses. However, because this depends on how the server is used, the best approach is to ask your tax accountant.

Summary

We compared 11 recommended hosting services for small businesses and corporations in detail and explained how to choose among them.

Because business hosting is more expensive than personal hosting, it is worth taking the time to choose carefully. Even so, if you are still undecided in the end, I recommend choosing from the following three providers.
