You can set up the machine to run a particular way, and even have parts of the machine independent of other parts.&lt;p&gt;Eventually parts get old and break down, or a flaw is found. This part needs to either be replaced or upgraded. With slotted services (CoreOS), you can replace an individual part and only affect that part of the machine, as long as it&amp;#x27;s not integral to the entire machine.&lt;p&gt;But the machine is complex. Sometimes you have to change how fast output shaft spins, or the gearing on a transmission. Or perhaps some other part of the machine&amp;#x27;s operation has to change, and that impacts this part because they connect to each other through more gears and pulleys. (comparison: API&amp;#x2F;ABI changes, database changes, network or protocol changes)&lt;p&gt;All slotted services do is provide momentary independence. They do not reduce overall support, and they only ease maintenance for that particular service. All other complex facets of server and service maintenance remain the same. The features of CoreOS - service discovery, systemd, a minimal OS, integrated deployment, etc - can all be provided with traditional linux distributions. CoreOS doesn&amp;#x27;t do anything new or difficult.&lt;p&gt;On top of that, by using such a specialized system to run your apps, you lose all the flexibility of having a full linux OS to troubleshoot and debug from. You now have to rely on them building on all the components that already exist in regular Linux world, like debuggers, tracers, sniffers, profilers, etc. You&amp;#x27;ll have to slip all that into your application deploy to troubleshoot a weird one-off bug. And forget about ever having a service contract that requires a supported OS like RHEL or Ubuntu.&lt;p&gt;This is a product designed to make them money via service and support contracts. In that sense, they may be successful. But as a sysadmin I know there&amp;#x27;s nothing this provides that I can&amp;#x27;t get from existing open source tools. Rebuilding the internet? More like repackaging.</text><parent_chain></parent_chain></comment><story><title>Linux Hackers Rebuild Internet From Silicon Valley Garage</title><url>http://www.wired.com/wiredenterprise/2013/08/coreos-the-new-linux/</url></story>
