After using wordpress and drupal for the last 10 years, I have migrated my blog to a platform similar to jekyll a static site generator. I have made this decision after my drupal accounts have been compromised thrice this year. Despite my knowledge for both systems [wordpress and drupal], recovery and clean up takes its tolls specially for their volumes and also for the other sites i'm hosting.
Nothing beats copy and paste in terms doing backup. Restoring a site generated site only involves copying your sqlite database and re-running the site builder / generator. If your site isn't really that large it might take less than a minute to an hour to get it done.
Third party services are everywhere from facebook api, disqus, mashape, tinypng, paypal and other notable cloud platforms. Although interfaces are not as ready as wordpress and drupal, integrating these api are not really that difficult.
Speed, memory and bandwidth, hosting aint cheap and site hitters are a pain. Optimized plain static html files are still the best for rendering the web, it can be easily cached and doesn't consume much of a badwidth.
Use platforms like bootstrap, jquery, primeui, angularjs and other various tools. These platforms are used by most website and their resources have defined cdn links, which makes it more efficient and reliable.
