Let’s hope it is another fifteen years before we suffer another hardware crash.
Werner Vogel, the CTO of Amazon Web Services (AWS) has made AWS the World's leader in data center as a service precisely because of what happened to GCA.com, and happens eventually to every other company at some point: stuff breaks. Instead of trying to engineer services that break less often, instead they started from the perspective that:
Everything Breaks, All The Time!
From this beginning, AWS has built an empire by architecting infrastructure that is designed to be accommodate stuff breaking. Hard drive breaks? No problem, data is redundantly stored. Data center catches fire? No problem, data is redundantly stored in multiple data centers. Server mother board craps out? No problem, server images are stored as data, and can be reinstantiated on some other server in seconds.
Netflix, famously, runs their streaming service out of Amazon. They had some high profile outages, and to correct against them, created a program called the "Chaos Monkey". This program randomly disables parts of their infrastructure, servers, storage, networks, etc., to ensure that the Netflix service can withstand failures. It works. And architecting systems to withstand failure works, too.
On peak times (think Christmas eve), when Americans sit around the TV to share a movie, 1/2 of US Internet traffic emanates from AWS. To handle that scale, in the past, service providers (Netflix, and GCA.com), would have to make huge investments in infrastructure. Now, AWS provides easily used tools that enable service providers to dynamically scale their servers and networks up and down in response to demand. US Open spike in course profiles? Setup the servers in an auto-scaling group at AWS, and as the servers get busy, peers will be created and brought on line. Demand wanes? Servers are decommissioned. Best part? Charges for new servers are by the hour (starting at about $0.10/hr).
Ran, as you look to the future, consider the new delivery models for Internet services. It really is an amazing new world out there. With a little planning, there is no need to have a hardware failure impact services.
