  Analysis Recently we implementedsome tags on our Azure Resources that enabled the company to create a dashboard detailing the Total Cost of Hosting for each of our applications.

  Resource Cost The typicalcost for a web app involving an App Service & an Azure SQL Server over 4 environments was: The cost of TradeBot was: £3000 per year £65 per year Or not enough to take my team out for lunch!

  Serverless Serverless is asub-category of PaaS services For a service to be described as ‘Serverless’ it must: 1. Cost nothing when you’re not using it (except storage) 2. Scale quickly and reactively to usage 3. Have zero maintenance and minimal configuration This leads to the key benefits: ‘Pay for what you use’, and ‘NoOps’.

  Why Serverless letsyou save cash • Most applications run at a fraction of their provisioned capacity, because we have to pre- provision enough capacity to deal with spikes without going offline • This leads to massive amount of waste, with many apps running at abysmal lifetime compute utilization in the single digit percentages. Serverless services instead scale their resources reactively, resulting in close to 100% utilization and only paying for what you use • Many apps also require more and more operational staff and tasks as you make them more complex. Serverless services will still require some, but the ratio of complexity to increase in staffing costs is much lower. All of this results in a significant TCO saving

  Sounds too goodto be true? • Your Serverless bill will increase with usage, which impacts predictability. Equally if your traffic is already very high, with high utilization, it’s entirely possible you won’t save in your raw hosting cost (but probably will in maintenance) • Tooling is not as good as ‘normal’ architectures currently • Cold starts can still be an issue for latency-sensitive apps, but possible to battle with ‘KeepAlive’ functions

  What is ServerlessMinimalism? A Serverless Minimalist creates applications using exactly what they need to complete the task at hand, and nothing more.

  Serverless Minimalist They donot: • Waste money by running resources permanently unused • Damage the planet by emitting greenhouse gases for these unused resources • Write more code than they need to do a job • Utilize ‘fat’ services like VM’s that have millions of lines of other peoples code sitting there doing nothing more than increasing our security surface area and emitting CO2 They do: • Use only the resources they need • Utilize managed services, which perform one job on a global scale • Write as little code as possible – When you first write code it is the least tested code in the world with the fewest customers & your company has to maintain it for the rest of its lifetime • Minimize all maintenance tasks
