Started in 2016 the open source serverless platform is designed to run any code, on any cloud, at any scale.<\/p>\n<p>During his session, Alex Ellis, VMWare, took us from 0 to serverless in 60 seconds (12 seconds to be exact!) and introduced us to the three core values of OpenFaaS \u2013 developer-first, operator friendly and community centric:<\/p>\n<ul>\n<li>Developer-first \u2013 to be simple, OpenFaaS gets out of your way<\/li>\n<li>Operator friendly \u2013 it\u2019s cloud native, light weight, and simple to deploy and operate<\/li>\n<li>Community centric \u2013 we know that one size doesn\u2019t always fit all so OpenFaaS is an open project, being built by a growing community of contributors<\/li>\n<\/ul>\n<p><img loading=\"lazy\" class=\"aligncenter wp-image-54402 size-medium\" src=\"http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/OpenFaaS-300x300.jpg\" alt=\"OpenFaaS\" width=\"300\" height=\"300\" srcset=\"http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/OpenFaaS-300x300.jpg 300w, http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/OpenFaaS-150x150.jpg 150w, http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/OpenFaaS.jpg 384w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>\u00a0<\/p>\n<h2>Serverless security \u2013 the good, the bad, the neutral<\/h2>\n<p>Now I\u2019m not one to play favourites but this really was a fantastic session from Guy Podjarny, Snyk. The general belief is that serverless = security, right? Not necessarily! While serverless brings with it a host of additional security measures, there are also numerous security risks which, if unaddressed, opens the door to attackers.<\/p>\n<p>Guy created a great slide which I\u2019ve inserted below on where security in serverless is better, neutral and worse. Well worth taking a look at to make sure your serverless platforms aren\u2019t left vulnerable.<\/p>\n<p>\u00a0<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter wp-image-54403\" src=\"http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/IMG_20181112_132045-1024x652.jpg\" alt=\"\" width=\"450\" height=\"287\" srcset=\"http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/IMG_20181112_132045-1024x652.jpg 1024w, http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/IMG_20181112_132045-300x191.jpg 300w, http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/IMG_20181112_132045-768x489.jpg 768w, http:\/\/content.n4stack.io\/wp-content\/uploads\/2018\/11\/IMG_20181112_132045-1080x688.jpg 1080w\" sizes=\"(max-width: 450px) 100vw, 450px\" \/><\/p>\n<p>\u00a0<\/p>\n<h2>Migrating an existing service to serverless &#8211; a 10-step process<\/h2>\n<p>As Chad said in his keynote, serverless will power the next 1B developers.
