Nowadays, developers everywhere are introduced to an application development trend called serverless computing. The trend isn’t new but rather an evolution culminating from a number of development methodologies, including service-oriented architecture (SOA), distributed cloud computing, Platform-as-a-service (PaaS) and Containers/Microservices. A key defining element of serverless computing is the serverless application’s logic that combines custom-developed code and 3rd-party service functionality.
Last week, 15 of us here at Cloudinary headed back to Las Vegas for the annual AWS re:Invent conference. We returned as exhibitors again this year since we had such a successful experience in 2015, when we introduced Cloudinary to many new companies that could benefit from our image and video management tools.
And so the song goes, well, more or less.
There really are an abundance of content delivery networks (CDNs) out there; and a time and a place in which each of those CDN services could win the race for fastest, most reliable, or best fit for for your resources. But somehow, you have to choose one, right?
JPEGs, PNGs, and GIFs — oh my! Most web developers only learn which format to use through trial, error, and long experience, and not necessarily by fully understanding how these formats actually work.
Update:
In this post, we clarify that not all browsers natively support HLS or MPEG-DASH, and thus in order to deliver adaptive streaming video to all devices, you should deliver it using a video player that supports your chosen format. In December of 2017, Cloudinary released its own Video Player, which enables you to easily embed a player in your web page that can stream any HLS or MPEG-DASH video. For details, see the Video Player announcement blog post and the Video Player documentation.
“Responsive.” Where did that term come from, anyways?
In his sea-changing essay, Responsive Web Design, Ethan Marcotte explained:
Recently, an emergent discipline called “responsive architecture” has begun asking how physical spaces can respond to the presence of people passing through them. Through a combination of embedded robotics and tensile materials, architects are experimenting with art installations and wall structures that bend, flex, and expand as crowds approach them. … rather than creating immutable, unchanging spaces … inhabitant and structure can—and should—mutually influence each other.
One of the main optimization challenges for website and mobile developers is how to display sufficiently high quality images to their visitors while minimizing the image file size. A smaller image file size can lead to faster load times, reduced bandwidth costs and an improved user experience. The problem is that reducing the file size too much may lead to a lower image quality and could harm visitor satisfaction. Delivering an optimized image with just the right balance between size and quality can be quite tricky.

Four years ago, Jason Grigsby asked a surprisingly difficult question: How do you pick responsive images breakpoints? A year later, he had an answer: ideally, we’d set responsive image performance budgets to achieve “sensible jumps in file size”. Cloudinary built a tool that implemented this idea, and the response from the community was universal: “Great! Now – what else can it do?” Today, we have an answer: art direction!
In economics, there is a concept referred to as “The Laffer Curve,” which illustrates how increases in government tax rates beyond a certain level will ultimately decrease tax revenue. It is often visualized with the following graph:
Video is an increasingly important component for websites and apps, as consumer demand for and consumption of video content is growing. It’s not only for wired devices, though. More and more, consumers are accessing video where they want it, when they want it, on whatever device that happens to be nearby.
