Do you recommend any of those for “testing purposes”? I am looking for a free hosting with a CPanel and easy WordPress installation and management; I fully understand that a testing website is not the same as a productive one but since it would up to the customer to find the best hosting to migrate (though I am helping a little bit on that project) and for my testing purposes paying is not precisely an option since none of those sites is where they would host their site at the end; I am looking for something free but that is good enough for me to work and test and to give a final demo to my customer

I was running a small private weather website in AWS and the satellite images got "picked up" by a news website and they regularly use them during major weather evenings. AWS' 12c per GB of outbound network traffic made things expensive and VPSServer makes this a lot more manageable and has excellent data volumes included with the price of the VPS. I also get many more CPUs for the price compared to AWS, so I am a happy customer.
This is unfortunate because, these days, owning a website is becoming a crucial part of running a successful business, and more and more folks are establishing a web presence for their personal brand as well. You can use hosting to sell online, store and share your portfolio, or even publish your freelance writing samples and resumé. Yet, even the basics — What is web hosting? — can be lost on the average web user.
