What are the scalability options for blogs hosted on Blogspot versus WordPress?

WordPress, especially WordPress.org, is highly scalable. As your blog grows, you can easily upgrade your hosting plan, install performance-enhancing plugins, and even migrate to more powerful servers without changing your platform. Blogspot's scalability is more limited, as it's a managed platform. While Google handles the infrastructure, you have less control over scaling resources and might encounter limitations as your traffic or content volume increases significantly.
