SRE Classroom: Practical Large Scale Design
Grand Ballroom C
Truly large-scale systems are still rare, and in a world of out-sourcing, and cloud-computing, it's harder for System Administrators to get the opportunity to design large systems. It's even harder to get the design right. Most organizations don't have the in-house expertise to build a large system, so outsource the detailed design to external contractors. If your organization doesn't have the expertise to design a large system, it's unlikely that it has the expertise to confirm a proposal is fit for your purposes and is cost effective.
While anyone can wave their hands convincingly, and come up with a rough outline of a large distributed system, those who can also fill in the detail are highly-prized. This class will teach you how to design software systems like Imgur and Twitter, then estimate the hardware needed to ensure you can deliver to a hard SLA. You will learn how requirements like queries-per-second, multi-site reliability, and data security impact the cost of implementation.
This will *not* cover concurrent programming and the software-engineering side of distributed systems.
System Admins who want to understand large systems, System Engineers who want to build large systems and business people who expect to procure large systems.
An ability to assess whether a design will work before it's built. The ability to communicate large system design with systems architects and business people. An ability to assess requirements, communicate constraints and predict performance of large systems before money is spent.
