The AdStage Migration from Heroku to AWS
This is a guest repost by G Gordon Worley III, Head of Site Reliability Engineering at AdStage.
When I joined AdStage in the Fall of 2013 we were already running on Heroku. It was the obvious choice: super easy to get started with, less expensive than full-sized virtual servers, and flexible enough to grow with our business. And grow we did. Heroku let us focus exclusively on building a compelling product without the distraction of managing infrastructure, so by late 2015 we were running thousands of dynos (containers) simultaneously to keep up with our customers.
We needed all those dynos because, on the backend, we look a lot like Segment, and like them many of our costs scale linearly with the number of users. At $25/dyno/month, our growth projections put us breaking $1 million in annual infrastructure expenses by mid-2016 when factored in with other technical costs, and that made up such a large proportion of COGS that it would take years to reach profitability. The situation was, to be frank, unsustainable. The engineering team met to discuss our options, and some quick calculations showed us we were paying more than $10,000 a month for the convenience of Continue reading
Introducing TLS with Client Authentication
In a traditional TLS handshake, the client authenticates the server, and the server doesn’t know too much about the client. However, starting now, Cloudflare is offering enterprise customers TLS with client authentication, meaning that the server additionally authenticates that the client connecting to it is authorized to connect.
TLS Client Authentication is useful in cases where a server is keeping track of hundreds of thousands or millions of clients, as in IoT, or in a mobile app with millions of installs exchanging secure information. For example, an IoT company can issue a unique client certificate per device, and then limit connections to their IoT infrastructure to only their devices by blocking connections where the client doesn’t present a certificate signed by the company’s certificate authority.
Or in the case of a mobile banking app, where the bank wants to ensure customers’ secure financial data doesn’t get stolen by bots spoofing their mobile app, they can issue a unique certificate to every app install and in the TLS handshake validate requests are coming from their mobile app. Client authentication is also useful for VPNs, enterprise networks or staging sites, where corporations and developers need to lock down connections to only laptops Continue reading
