The availability of a website is measured by the percentage of a year in which the website is publicly accessible and reachable via the Internet. This is different from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it as in the event of a network outage.[citation needed] A hosting provider's Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the systems. This scheduled downtime is often excluded from the SLA timeframe, and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a system drops below that in the signed SLA, a hosting provider often will provide a partial refund for time lost. How downtime is determined changes from provider to provider, therefore reading the SLA is imperative.[11] Not all providers release uptime statistics.[12] Most hosting providers will guarantee at least 99.9% uptime which will allow for 43m of downtime per month, or 8h 45m of downtime per year.
Managed web hosting brings a white-glove or concierge service to the hosting experience. The term “managed” means the hosting company takes care of the hands-on IT work required to keep the server running optimally. They handle the hardware while you maintain the software and your site databases, files, and media content. This type of web hosting carries the highest price tag, but many find the peace of mind and server administration assistance worthwhile.

Getting your website off the ground requires a great web hosting service. In our evaluation of web hosting providers, we looked at key features that make for a positive web hosting experience and compared the leading providers in the industry. The factors we considered included uptime, website builders, and eCommerce integration. Read on to learn more about the features you should look at when determining which provider and plan is best for you.
Usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some ISPs actively attempt to block home servers by disallowing incoming requests to TCP port 80 of the user's connection and by refusing to provide static IP addresses. A common way to attain a reliable DNS host name is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.[10]

On the plus side, SiteGround offers free automatic daily backups, access to the Cloudflare CDN, high-performance SSDs for all plans, unlimited email accounts and integration of the free LetsEncrypt SSL certificate into sites. The company does limit bandwidth and storage, but even those who claim to offer so-called unlimited bandwidth and storage really have some limits in its terms of service. 

Having multiple servers hosting the same content for better resource utilization. Clustered servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Usually web hosts use clustered hosting for their shared hosting plans, as there are multiple benefits to the mass managing of clients).[9] 

You can also find that some WordPress-centric hosting companies, like WPEngine offer expensive managed hosting services. It’s built specifically for running WordPress websites on it, and it’s optimized for speed, security, and scalability.

Source: Hosting Tribunal (2019)Getting reliable hosting is the most important decision you will make: without it, even the best-crafted site won’t make any sense. Adjusted to your scope of operations, hosting will eliminate the risk you’re taking by adhering to free-to-use networks and services, and put you in absolute control over how your data is accessed and managed. Better yet, paid-for hosting unties your hands to brand a website as you want it, and use all the tools and plugins that can help your business. Meantime, hosting pulls the strings of all key performance metrics such as the site’s promotion on search engines and its loading speed.The king of all benefits will nonetheless remain security—unless you’re ready to bounce off attacks and intrusions all by yourself.Which are the best web hosting companies? There is no standardized answer to this question, as each site owner has a unique list of requirements a service must respond to. At the beginning of this demanding process, however, we should shortlist the systems that cater to our needs, which we can afford.1.

I want to ask I’m a student and we will have an assignment in our school for next half year it’s my last year and this is project will decide my mark (grade). I want to make a blog and I don’t need any top-noch hosting for this. The site is potential going to be shut down after this project. So my question is do you recommend any of the hostings above.
HostGator gained points for uptime monitoring and regular backups, along with free cPanel or Plesk. We liked that SSH is available for the more technically inclined site operators and that dedicated IP addresses could be purchased. We did take points off because it's sometimes difficult to tell what the price is once promotional plans run their course. That said, with a generous 45-day money back guarantee, there's a hosting solution for almost everyone at HostGator.
