This 1992 lecture at MIT from Steve Jobs will teach you more about product and sales than most 2 year MBA programs Crazy just how ahead of his time this man truly was
𝗦𝘁𝗮𝗰𝗸 𝗢𝘃𝗲𝗿𝗳𝗹𝗼𝘄 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 𝗜𝘀 𝗡𝗼𝘁 𝗪𝗵𝗮𝘁 𝗬𝗼𝘂 𝗠𝗲𝗮𝗻 𝗜𝘁 𝗜𝘀 In the recent interview with Scott Hanselman, 𝗥𝗼𝗯𝗲𝗿𝘁𝗮 𝗔𝗿𝗰𝗼𝘃𝗲𝗿𝗱𝗲, 𝗛𝗲𝗮𝗱 𝗢𝗳 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗮𝘁 𝗦𝘁𝗮𝗰𝗸 𝗢𝘃𝗲𝗿𝗳𝗹𝗼𝘄, revealed the story about the architecture of Stack Overflow. They handle more than 6000 requests per second, 2 billion page views per month, and they manage to render a page in about 12 milliseconds. If we think about it a bit, we could imagine they use some kind of 𝗺𝗶𝗰𝗿𝗼𝘀𝗲𝗿𝘃𝗶𝗰𝗲 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 𝘁𝗵𝗮𝘁 𝗿𝘂𝗻𝘀 𝗶𝗻 𝘁𝗵𝗲 𝗖𝗹𝗼𝘂𝗱 𝘄𝗶𝘁𝗵 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀. But the story is a bit different. Their solution is 15 years old, and it is a 𝗯𝗶𝗴 𝗺𝗼𝗻𝗼𝗹𝗶𝘁𝗵𝗶𝗰 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻 𝗿𝘂𝗻𝗻𝗶𝗻𝗴 𝗼𝗻-𝗽𝗿𝗲𝗺𝗶𝘀𝗲𝘀. It is actually 𝗮 𝘀𝗶𝗻𝗴𝗹𝗲 𝗮𝗽𝗽 on IIS, which runs 200 sites. This single app is running on nine web servers and a single SQL Server (with the addition of one hot standby). They also use 𝘁𝘄𝗼 𝗹𝗲𝘃𝗲𝗹𝘀 𝗼𝗳 𝗰𝗮𝗰𝗵𝗲, one on SQL Server with large RAM (1.5TB), where they have 30% of DB access in RAM and also they use two Redis servers (master and replica). Besides this, they have 3 tag engine servers and 3 Elastic search servers, which are used for 34 million daily searches. All this is handled by a 𝘁𝗲𝗮𝗺 𝗼𝗳 𝟱𝟬 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝘀, who manage to 𝗱𝗲𝗽𝗹𝗼𝘆 𝘁𝗼 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗶𝗻 𝟰 𝗺𝗶𝗻𝘀 several times daily. Their 𝗳𝘂𝗹𝗹 𝘁𝗲𝗰𝗵 𝘀𝘁𝗮𝗰𝗸 is: 🔹 C# + ASP. NET MVC 🔹 Dapper ORM 🔹 StaeckExchange Redis 🔹 MiniProfiler 🔹 Jil JSON Deseliazier 🔹 Exceptional logger for SQL 🔹 Sigil, a .Net CIL generation helper (for when C# isn’t fast enough) 🔹 NetGain, a high-performance web socket server 🔹 Opserver, monitoring dashboard polling most systems and feeding from Orion, Bosun, or WMI. 🔹 Bosun, backend monitoring system, written in Go Check more links in the comments. #technology #softwareengineering #programming #techworldwithmilan #softwarearchitecture
Microservices are the most scalable way to build software, but if you don't need to scale, they are often a less efficient way to organise your work. This video explains my thinking a bit further... 14/14 youtu.be/bWZVx6TgVvc
Continuous improvement is better than delayed perfection
Dear people who don't let people refactor or test their code...
@shashban hi, is someone maintaining this plugin? github.com/microsoft/azur… Would be great to have progress with YAML Pipelines there.

To make error is human. To propagate error to all server in automatic way is #devops.
Facebook employees can’t enter the headquarters because their badges don’t work, and those already inside can’t enter various rooms because access is linked through the IoT (Internet of Things) and so goes through the same DNS routes that no longer exist: #FacebookDown
