Amazon Lightsail by Amazon Web Services is targeted towards new webmasters, server admins, DIY enthusiasts among others. It provides much more predictable pricing than EC2 based servers where the pricing is calculated as a cumulative cost of individual components (server, disk, bandwidth, etc).
Right after creating my first WordPress plugin, Auto Maintenance Mode, I came across a situation on a high-traffic blog where the visitors just rush to the website immediately after a blog post is published and shared (automatically) via social media. It created chaos in the server and the initial visitors didn’t get the cached version of the blog post, because it wasn’t even ready.
It isn’t uncommon to see freemium plugins in the official WordPress repo. The basic functionality of the plugin would be free. Some fancy features would come with a premium price. There is nothing wrong with such business model. What’s bad (business model) is switching the free features into paid features without notification. How does it feel if WordPress Foundation started charging a small fee to use the theme customizer?
