A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.
WordPress is one of the most popular content management systems (CMS) in the world, and as such, many web hosting providers offer options that cater to this rather large niche. You can certainly host your WordPress site on a standard shared hosting plan, but by choosing a WordPress-specific option, you'll spend less time configuring and managing your WordPress installation.
Anycast DNS - When typing in a domain name, traditional DNS works by translating that domain name into the IP address where that website can be found. The computer is connected with the web host and the web site can be viewed once this IP address is located. Thie DNS record is located on a DNS server found in one location. For example, if you're located in the United Kingdom, but your visitor is located in the United States, it can take some time for that DNS server and your visitor's computer to communicate with each other. This can slow down how fast a web page loads. A2 Hosting uses Anycast DNS because that resolves this issue. Instead of just one DNS location, Anycast DNS copies your DNS record on our network of global servers. This means that your DNS record is much closer to your visitors and Anycast can direct visitors to a DNS server located more closely to them. In short, Anycast DNS is another A2 Hosting solution that can help your site load even faster for your visitors.
Shared hosting is web hosting in which the provider houses multiple sites on a single server. For example, Site A shares the same server with Site B, Site C, Site D, and Site E. The upside is that the multiple sites share the server cost, so shared web hosting is generally very inexpensive. In fact, you can find an option for less than $10 per month.
