How do dedicated servers, virtual machines, containers & functions differ? 🤖

An overview of the different compute models ↓

𝗗𝗲𝗱𝗶𝗰𝗮𝘁𝗲𝗱 𝗦𝗲𝗿𝘃𝗲𝗿𝘀 (1/2) 🛠

A physical server, only utilized by you
• you have to know or guess the CPU & memory capacities you need
• high risk of overpaying (underutilized server) or under-provisioning (too much load)

𝗗𝗲𝗱𝗶𝗰𝗮𝘁𝗲𝗱 𝗦𝗲𝗿𝘃𝗲𝗿𝘀 (2/2) 🛠

• you're able to run multiple apps, but need to make sure that you're not causing conflicts by resource sharing
• you're solely responsible for the security
• up- or downscaling is tedious & not quickly possible

𝗩𝗶𝗿𝘁𝘂𝗮𝗹 𝗠𝗮𝗰𝗵𝗶𝗻𝗲𝘀 🤖

Running a machine in a machine
• sharing a physical server with multiple customers
• only paying for your provisioned capacities → a fraction of the whole server
• still having risks regarding provisioning & resource sharing

𝗖𝗼𝗻𝘁𝗮𝗶𝗻𝗲𝗿𝘀 🐳

Another abstraction & encapsulation which will run on a virtual machine
• multiple containers can run on the same virtual machine
• containers are sharing the underlying OS, but are not limited by them
• greatly reduced operational management

𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝘀 ƛ

Highest abstraction, as you're only bringing your code
• your code is running on a managed VM within managed containers
• still provisioning capacities like memory
• low responsibility: only your code & data
• only pay for the time your code is executed
