How green is the cloud?

As a society we’ve come to depend so much on cloud computing that we think of it as a “set and forget” resource (if we think of it at all). We are reassured by its ubiquity and the ease with which we can easily spin up new cloud instances to meet our immediate capacity or performance needs. The cloud has essentially created a false sense of security, as many businesses have learned during the Covid crisis. As they went to expand their capacity in the face of unseen demand, they found that the cloud is also finite. When things settled down after the initial rush as Covid lockdowns took effect, cloud providers returned to normal. But the new extremes of use showed how taking the cloud for granted isn’t difficult. If you’re not the one taking care of hardware or infrastructure yourself, it’s invisible.

Nowadays containers are ubiquitous, so we can skip the basics, and thanks to the dockerhub images, we don't even need to write our own Dockerfile like we used to. Ain't that nice?

Our base will look a lot like the previous setup, but for this specific blog post, we are going to focus almost exclusively on how to integrate Hitch with Varnish. As you will see it is very straightforward thanks to upstream work, but it will be an opportunity to explore a few interesting notions along the way.

The OTT opportunity in APAC

In the diverse Asia-Pacific (APAC) region, over-the-top (OTT) video streaming has exceeded growth expectations and become a compelling entertainment source for consumers across the entire region. According to recent research, OTT has hit critical mass. To strike while there’s still opportunity to make inroads in one or many of these markets, it’s time to tap into both regional content preferences and the technology that will enable future-proof OTT streaming.
