A handful of domains will have restrictions on them, which means you can only purchase them if you meet or exceed certain criteria or have authorization (some examples are .gov, .edu and .mil). But most extensions are available to everyone. In fact, most country code Top Level Domains (ccTLDs) are available for anyone to purchase, even if you don't reside in the country code in question.
Don't get discouraged in your domain name search if what you're looking for is already taken. We have a couple of ways for dealing with such a situation. You can try our Domain Broker Service, where we negotiate acquiring the domain from its current owner. We also offer a Domain Backorder service, where you purchase a backorder credit to give you a chance to get the domain when it goes into auction.
You can build a profile on 500px, and photographers can sell usage of their photos through the site. However, you can’t directly link to photos on other websites. If you’re looking for a platform to upload photos to share on social media or other sites 500px probably isn’t the best option for you. The primary benefit of 500px is the opportunity to display your work and network with other photographers.
One option not mentioned in the article is Amazon Photos. Even though I’m an Amazon “prime” customer, I had never really given their photo storage much thought because I already had several sites I use for photo sharing and storage. However, I recently learned that they will store your photos in their original size AND your RAW (CR2, NEF, ARW….) photos too! This is a HUGE advantage for me.
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).
The host may also provide an interface or control panel for managing the Web server and installing scripts, as well as other modules and service applications like e-mail. A web server that does not use a control panel for managing the hosting account, is often referred to as a "headless" server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.).
